Newly designed battery-free wireless dosimeters can passively, continuously, and accurately measure electromagnetic radiation in numerous environments, according to three studies of the millimeter-scale near-field communication (mm-NFC) devices.

S.Y. Heo et.al. Science Translational Medicine, 2018
The solar radiation sensors are flexible and can detect multiple forms of ultraviolet radiation.

“These studies highlight the differences between mm-NFC dosimeters and commercial devices in real-world, practical scenarios,” wrote lead author Seung Yun Heo of the department of biomedical engineering at the Center for Bio-Integrated Electronics at Northwestern University, Chicago, and her coauthors. “The former operate in continuous, uninterrupted modes, whereas the latter capture instantaneous values of intensity at preprogrammed intervals,”they noted. The study was published in Science Translational Medicine.

Separate studies to assess the performance of these “flexible” dosimeters took place in Rio de Janeiro, Brazil, and St. Petersburg, Fla. The Florida study included 13 healthy participants who wore skin-mounted mm-NFC ultraviolet A (UVA) dosimeters on the right back hand, left back hand, left inner arm, and left outer arm, plus a commercial dosimeter on the right wrist. The volunteers walked a 6.44-km path three times: a morning and subsequent afternoon stroll, plus an evening walk 4 days later. Four devices failed during the afternoon exercise, but otherwise, participants received data on their smartphones via the dosimeters at 30-minute intervals.

The Brazilian study was made up of nine healthy participants who wore mm-NFC UVA dosimeters on the thumbnail or the middle fingernail; commercial dosimeters were worn on the wrist of the ipsilateral side. These volunteers engaged in rooftop recreational activities that corresponded to solar zenith angles, along with showering and swimming with the use of soap and skin creams. All sensors remained functional over the 4 days of testing, and 14 of 20 devices remained adhered to the fingernail. Accumulated doses ranged widely, “as expected on the basis of the differences in behaviors,” the authors wrote. These observations imply highly variable UV-associated risks between participants, due not only to differences in Fitzpatrick skin types but also to individual behavior patterns,” they added.

The third study of mm-NFC blue light dosimeters comprised three newborns in an Urbana, Ill., neonatal ICU undergoing blue light phototherapy treatments. Nurses mounted dosimeters on the patients’ chests before phototherapy; an antenna underneath the incubator mattress transmitted continuous wireless measurements of blue intensity and dosage at 20-minute intervals for 20 hours.

The authors acknowledged that these devices and their designs have limitations, including a small detection area as compared to the surface area of a human body. The study’s results “represent localized measurements of exposure, whereas the sun irradiance profile across the body surface is not uniform and varies by position of the sun in the sky over the course of a day.” They recommended that future research could “create anatomic specific risk assessment of UV exposure” via multinodal sensing with UVA/UVB dosimeters on several parts of the body.

The Brazilian UV study was sponsored by La Roche Posay and L’Oreal California Research Center. Research was supported by the National Cancer Institute. Five of the authors reported commercial interests in the technology. Another author reported paid consultation for Aclaris Therapeutics.

Patients receiving oral anticoagulant treatment had the lowest risk of gastrointestinal bleeding when taking apixaban, compared with rivaroxaban, dabigatran, and warfarin, according to a recent study.

Further, patients who received proton pump inhibitor (PPI) cotherapy had a lower overall risk of gastrointestinal bleeding, according to Wayne A. Ray, PhD, from the department of health policy at Vanderbilt University, Nashville, Tenn., and his colleagues.

“These findings indicate the potential benefits of a gastrointestinal bleeding risk assessment before initiating anticoagulant treatment,” Dr. Ray and his colleagues wrote in their study, which was published in JAMA.

Dr. Ray and his colleagues performed a retrospective, population-based study of 1,643,123 Medicare beneficiaries (mean age, 76.4 years) who received 1,713,183 new episodes of oral anticoagulant treatment between January 2011 and September 2015. They analyzed how patients reacted to apixaban, dabigatran, rivaroxaban, or warfarin both with and without PPI cotherapy.

Overall, the risk of gastrointestinal bleeding across 754,389 person-years without PPI therapy was 115 per 10,000 person-years (95% confidence interval, 112-118) in 7,119 patients. The researchers found the risk of gastrointestinal bleeding was highest in patients taking rivaroxaban (1,278 patients; 144 per 10,000 person-years; 95% CI, 136-152) and lowest when taking apixaban (279 patients; 120 per 10,000 person-years; incidence rate ratio, 1,97; 95% CI, 1.73-2.25), compared with dabigatran (629 patients; 120 per 10,000 person-years; IRR, 1.19; 95% CI, 1.08-1.32) and warfarin (4,933 patients; 113 per 10,000 person-years; IRR, 1.27; 95% CI, 1.19-1.35). There was a significantly lower incidence of gastrointestinal bleeding for apixaban, compared with warfarin (IRR, 0.64; 95% CI, 0.57-0.73) and dabigatran (IRR, 0.61; 95% CI, 0.52-0.70).

There was a lower overall incidence of gastrointestinal bleeding when receiving PPI cotherapy (264,447 person-years; 76 per 10,000 person-years), compared with patients who received anticoagulant treatment without PPI cotherapy (IRR, 0.66; 95% CI, 0.62-0.69). This reduced incidence of gastrointestinal bleeding was also seen in patients receiving PPI cotherapy and taking apixaban (IRR, 0.66; 95% CI, 0.52-0.85), dabigatran (IRR, 0.49; 95% CI, 0.41-0.59), rivaroxaban (IRR, 0.75; 95% CI, 0.68-0.84), and warfarin (IRR, 0.65; 95% CI, 0.62-0.69).

The researchers noted that limitations in this study included potential misclassification of anticoagulant treatment, PPI cotherapy, and NSAIDs because of a reliance on filled prescription data; confounding by unmeasured factors such as aspirin exposure or Helicobacter pylori infection; and gastrointestinal bleeding being measured using a disease risk score.

This study was supported by a grant from the National Heart, Lung, and Blood Institute. The authors reported no relevant conflicts of interest.

ONC releases draft strategy on reducing EHR burden

Article Type
Changed
Wed, 04/03/2019 - 10:19

 

A new federal proposal aims to move you away from the keyboard and back face-to-face with your patients.

Dr. Kate Goodrich

The draft strategy from the Office of the National Coordinator for Health IT has three aims: to reduce the time and effort to record information in EHRs; to reduce the time and effort required to meet regulatory requirements; and to improve the functionality and ease of use of EHRs.

“This draft strategy includes recommendations that will allow physicians and other clinicians to provide effective care to their patients with a renewed sense of satisfaction for them and their patients,” Andrew Gettinger, MD, chief clinical officer at ONC, and Kate Goodrich, MD, chief medical officer at the Centers for Medicare & Medicaid Services, wrote in a recent blog post. “We are taking one more step toward improving the interoperability and usability of health information by establishing a goal, strategy, and recommendations to reduce regulatory and administrative burdens relating to the use of EHRs.”

To ease documentation burdens, the proposal seeks to “mitigate the EHR-related burden associated with a variety of administrative processes,” the draft strategy notes. “We are considering how reforming certain administrative requirements or optimizing out-of-date requirements for health IT–enabled health care provider work flows can reduce the burden of clinical documentation.”

Specifically, ONC proposes to reduce the overall regulatory burden, leverage data present in the electronic record to reduce the redocumentation, waive certain documentation requirements for participants in advanced alternative payment models (APMs), and promote standardized documentation for ordering and prior authorization.

To improve health IT usability, the draft strategy aims to “address how improvements in the design and use of health IT systems” can reduce burden and calls on clinicians, software developers, and other vendors to collaborate.

To do so, ONC recommends better alignment between EHR design and clinical work flow and making improvements to clinical decision support, as well as improving the presentation of clinical data within EHRs and clinical documentation functionality.

ONC also recommends standardizing basic clinical operations across all EHRs, designing EHR interfaces that are standard to health care delivery, and better integration of the EHR with the exam room.

The draft strategy also includes recommendations to help doctors better understand the financial requirements for successful implementation and optimize the log-in procedures to help reduce burden.

EHR reporting strategies “are designed to address many of the programmatic, technical, and operational challenges raised by stakeholders to reduce EHR-related burden associated with program reporting.”

ONC wants to simplify scoring for the “promoting interoperability” performance category in the Merit-based Incentive Payment System (MIPS) track of the Quality Payment Program and improving other measures of health IT usage; applying additional data standards to make data access, extraction, and integration across multiple systems easier and less costly; and exploring alternate, less burdensome approaches to electronic quality measurement through pilot programs and reporting program incentives.

Finally, public health reporting strategies “look at a set of topics linked to federal, state, local, territorial, and tribal government policies and public health programs, with a specific focus on EPCS [electronic prescribing for controlled substances] and PDMPs [prescription drug monitoring programs]. Where EHR-related burden remains a key barrier to progress in these areas, there are several recommendations for how stakeholders can advance these burden reduction goals related to public health.”

In this area, ONC is recommending increasing adoption of e-prescribing of controlled substances with access to medication history to better inform prescribing of controlled substances, harmonizing reporting requirements across federally funded programs to streamline reporting requirements, and providing better guidance about HIPPA and federal confidentially requirements governing substance abuse disorder to better facilitate the electronic exchange of health information for patient care.

Comments on the report may be submitted electronically through Jan. 28, 2019.

ONC wants to simplify scoring for the “promoting interoperability” performance category in the Merit-based Incentive Payment System (MIPS) track of the Quality Payment Program and improving other measures of health IT usage; applying additional data standards to make data access, extraction, and integration across multiple systems easier and less costly; and exploring alternate, less burdensome approaches to electronic quality measurement through pilot programs and reporting program incentives.

Finally, public health reporting strategies “look at a set of topics linked to federal, state, local, territorial, and tribal government policies and public health programs, with a specific focus on EPCS [electronic prescribing for controlled substances] and PDMPs [prescription drug monitoring programs]. Where EHR-related burden remains a key barrier to progress in these areas, there are several recommendations for how stakeholders can advance these burden reduction goals related to public health.”

In this area, ONC is recommending increasing adoption of e-prescribing of controlled substances with access to medication history to better inform prescribing of controlled substances, harmonizing reporting requirements across federally funded programs to streamline reporting requirements, and providing better guidance about HIPPA and federal confidentially requirements governing substance abuse disorder to better facilitate the electronic exchange of health information for patient care.

2018: A banner year for hematology drug approvals

Article Type
Changed
Thu, 01/12/2023 - 10:45

– It was banner year for new hematology drug approvals, according to R. Angelo de Claro, MD, of the Food and Drug Administration.

So far in 2018 there have been 32 new malignant hematology and nonmalignant hematology drug approvals by the FDA, including 12 first-time approvals, 5 new biosimilars, and 15 new indications for previously approved drugs, Dr. de Claro, clinical team leader in the FDA’s division of hematology products in Silver Spring, Md., said during an overview of the approvals at the annual meeting of the American Society of Hematology.

These include six new approvals for first-line treatment, and eight for pediatric indications, he said.

Highlights were discussed at two ASH-FDA joint symposia at the meeting, including one focused on the malignant hematology approvals, and another on the nonmalignant hematology approvals. In a video interview, Dr. de Claro provides some additional insight into their importance and about what might lie ahead.

“I think what’s exciting is that you have drug development occurring in more common conditions such as chronic lymphocytic leukemia, as well as in rare conditions, including hairy cell leukemia – and the first-ever approval in hemophagocytic lymphohistiocytosis,” he said. “It’s been very busy at the FDA; stay tuned ... the year’s not done yet. There could be more coming and we certainly anticipate more applications in the future.”

Dr. de Claro is an FDA employee. He reported having no other relevant disclosures.

Patient treatment expectations can outweigh equivocal effectiveness data

Article Type

Thu, 03/28/2019 - 14:31

 

I’m getting old and starting to fall apart. Recently, I suffered a lumbar radiculopathy when I injured myself sneezing. (No, really, I did.)

lolostock/Thinkstock

So, as time went by and I didn’t get better, I began looking stuff up. When patients come to me for this, I go through the standard conservative regimen of NSAIDs, physical therapy, steroid tapers ... the standard stuff.

But, when I began looking these things up, I was surprised to find out how much of what we do (at least for lumbar radiculopathy) is taken on faith.

I went through UpToDate, the modern Bible of medicine.

NSAIDs and acetaminophen, to my surprise, have only marginal proof of efficacy for acute lumbosacral radiculopathy pain. Several pooled analyses showed a nonsignificant trend to support their use, and the quality of the data was considered to be low.

Likewise, physical therapy also had “no convincing evidence that such treatments are effective for this indication.” Admittedly, some of the data may be affected by the difficulty in doing sham therapy as part of a placebo controlled-trial.

An oral steroid taper? Again, similar, equivocal data. Marginal improvement in functional capabilities, no improvement in pain, and no improvement in the rate of surgery at 1 year out.

But these are the things that I, and likely most family doctors, physiatrists, and other neurologists recommend on a daily basis. And, in all likelihood, will continue to do so.

Why?

Overall, they are benign when used correctly and in the right patients. That isn’t to say everyone should get them. All drugs have issues, and patients have to be carefully matched to specific treatments.

But, in the grand scheme of “do no harm,” physical therapy, NSAIDs, acetaminophen, or a few days of steroids are reasonably harmless. There certainly are some patients who will benefit, and none of these approaches have clearly been shown to be dangerous.

There’s also patient expectations. They didn’t come to us, or shell out a copay, to be told that “nothing helps, give it time.” We’re the doctors, and they want us to DO SOMETHING. So even if these treatments may be placebos, they still help if for no other reason than (as Voltaire said) to amuse the patient while nature cures the disease.

And getting them better is, after all, a big part of our job.

Dermoscopy in family medicine: A primer

Dermoscopy in family medicine: A primer

Dermoscopy, the use of a handheld instrument to magnify the skin 10-fold while providing a light source, is a quick, useful, cost-effective tool for detecting melanoma in family medicine.1-4 The device, which allows the physician to visualize structures below the stratum corneum that are not routinely discernible with the naked eye, can be attached to a smartphone so that photos can be taken and reviewed with the patient. The photo can also be reviewed after a biopsy result is obtained.

Its use among non-dermatologist US physicians appears to be relatively low, but rising. One small study of physicians working in family medicine, internal medicine, and plastic surgery found that only 15% had ever used a dermatoscope and 6% were currently using one.5

As a family physician, you can expand your diagnostic abilities in dermatology with the acquisition of a dermatoscope (FIGURE 1) and some time invested in learning to interpret visible patterns. With that in mind, this review focuses on the diagnosis of skin cancers and benign growths using dermoscopy. We begin with a brief look at the research on dermoscopy and how it is performed. From there, we’ll detail an algorithm to guide dermoscopic analysis. And to round things out, we provide guidance that will help you to get started. (See “Choosing a dermatoscope—and making the most of it,” and “To learn more about dermoscopy …”.)

A sampling of dermatoscopes

SIDEBAR
Choosing a dermatoscope—and making the most of it

1. Consider acquiring a hybrid dermatoscope.

Nonpolarized dermatoscopes (NPDs) and polarized dermatoscopes (PDs) provide different but complementary information. PDs enable users to identify features such as vessels and shiny white structures that are highly indicative of skin cancer. Because PDs are highly sensitive for detecting skin cancer and do not require a liquid interface or direct skin contact, they are the ideal dermatoscopes to use for skin cancer screening.

However, maintaining the highest specificity requires the complementary use of NPDs, which are better at identifying surface structures seen in seborrheic keratoses and other benign lesions. Thus, if the aim is to maintain the highest diagnostic accuracy for all types of lesions, then the preferred dermatoscope is a hybrid that permits the user to toggle between polarized and nonpolarized features in one device.

2. Choose a dermatoscope that attaches to your smartphone and/or camera.

This helps you capture digital dermoscopic images that can be analyzed on a larger screen, which permits:

  • enlarging certain areas for in-depth analysis of structures and patterns
  • sharing the image with the patient to explain why a biopsy is, or isn’t, needed
  • sharing the image with a colleague for the purpose of a consult or a referral, or using the images for teaching purposes
  • saving the images in order to follow lesions over time when monitoring is indicated
  • ongoing learning. After each biopsy result comes back, we recommend correlating the dermoscopic images with the biopsy report. If your suspected diagnosis was correct, this reinforces your knowledge. If the pathology diagnosis is unexpected, you can learn by revisiting the original images to look for structures or patterns you may have missed upon first examination. You may even question the pathology report based on the dermoscopy, prompting a call to the pathologist.
  • keeping a safe distance from the patient when looking for scabies mites.

What the research says

Dermoscopy improves sensitivity for detecting melanoma over the naked eye alone; it also allows for the detection of melanoma at earlier stages, which improves prognosis.6

A meta-analysis of dermoscopy use in clinical settings showed that, following training, dermoscopy increases the average sensitivity of melanoma diagnosis from 71% to more than 90% without a significant decrease in specificity.7 In a study of 74 primary care physicians, there was an improvement in both clinical and dermoscopic diagnosis of melanoma among those who received training in dermoscopy, compared with a control group.8 Another study found that primary care physicians can reduce their baseline benign-to-melanoma ratio (the number of suspicious benign lesions biopsied to find 1 melanoma) from 9.5:1 with naked eye examination to 3.5:1 with dermoscopy.9

The exam begins by choosing 1 of 3 modes of dermoscopy

Dermatoscopes can have a polarized or nonpolarized light source. Some dermatoscopes combine both types of light (hybrid dermatoscopes; see “Choosing a dermatoscope—and making the most of it.”)

There are 3 modes of dermoscopy:

  1. nonpolarized contact dermoscopy
  2. polarized contact dermoscopy
  3. polarized non-contact dermoscopy.

Dermatoscopes with nonpolarized light require direct skin contact and a liquid interface (eg, alcohol, gel, mineral oil) between the scope’s glass plate and the skin for the visualization of subsurface structures. In contrast, dermatoscopes with polarized light do not require direct skin contact or a liquid interface; however, contacting the skin and using a liquid interface will provide a sharper image.

Two major algorithms guide dermoscopic analysis

The first of 2 major algorithms that can be used to guide dermoscopic analysis is a modified pattern analysis put forth by Kittler.10 This descriptive system based on geometric elements, patterns, colors, and clues guides the observer to a specific diagnosis without categorizing lesions as being either melanocytic or nonmelanocytic. Because this is not the preferred method of the authors, we will move on to Method 2.

The second method, a 2-step algorithm, is a qualitative system that guides the observer through differentiating melanocytic from nonmelanocytic lesions in order to differentiate nevi from melanoma (FIGURE 2). At the same time, it serves as an aid to correctly diagnose non-melanocytic lesions. The 2-step algorithm forms the foundation for the dermoscopic evaluation of skin lesions in this article.

A 2-step algorithm for dermatoscopic diagnosis of skin lesions

Not all expert dermoscopists employ structured analytical systems or methods to reach a diagnosis. Because of their vast experience, many rely purely on pattern recognition. But algorithms can facilitate non-experts in dermoscopy in the differentiation of nevi from melanoma or, simply, in differentiating the benign from the malignant.

Although each algorithm has its unique criteria, all of them require training and practice and familiarity with the terms used to describe morphologic structures. The International Dermoscopy Society recently published a consensus paper designating some terms as preferred over others.11

Continue to: Step 1...

 

 

Step 1: Melanocytic vs non-melanocytic

Step 1 of the 2-step algorithm requires the observer to determine whether the lesion is melanocytic (ie, originates from melanocytes and, therefore, could be a melanoma) or nonmelanocytic in origin.

A melanocytic lesion usually will display at least 1 of the following structures:

  • pigment network (FIGURE 3A) (This can include angulated lines.)
  • negative network (FIGURE 3B) (hypopigmented lines connecting pigmented structures in a serpiginous fashion)
  • streaks (FIGURE 3C)
  • homogeneous blue pigmentation (FIGURE 3D)
  • globules (aggregated or as a peripheral rim) (FIGURE 3E)
  • pseudonetwork (facial skin) (FIGURE 3F)
  • parallel pigment pattern (acral lesions) (FIGURE 3G).

Features of melanocytic lesions

Exceptions. Sometimes, nonmelanocytic lesions will present with pigment network. Dermatofibromas, for example, are one exception in which the pattern trumps the network. Two other exceptions are solar lentigo and supernumerary or accessory nipple.

If the lesion does not display any structure, it is considered structureless. In these cases, proceed to the second step to rule out a melanoma.

Doesn’t meet criteria for a melanocytic lesion?

If the lesion does not reveal any of the criteria for a melanocytic lesion, then look for structures seen in nonmelanocytic lesions: dermatofibromas; seborrheic keratosis; angiomas and angiokeratomas; sebaceous hyperplasia; clear-cell acanthomas; basal cell carcinomas (BCCs); and squamous cell carcinomas (SCCs).

Continue to: Benign nonmelanocytic lesions

 

 

Benign nonmelanocytic lesions

Dermatofibromas are benign symmetric lesions that feel firm and may dimple upon application of lateral pressure. They are fibrotic scar-like lesions that present with 1 or more of the following dermoscopic features (FIGURE 4):

  • peripheral pigment network, due to increased melanin in keratinocytes
  • homogeneous brown pigmented areas
  • central scar-like area
  • shiny white lines
  • vascular structures (ie, dotted, polymorphous vessels), usually seen within the scar-like area
  • ring-like globules, usually seen in the zone between the scar-like depigmentation and the peripheral network. They correspond to widened hyperpigmented rete ridges.

A dermatofibroma

Seborrheic keratosis (SK) is a benign skin growth that often has a stuck-on appearance (FIGURE 5). Features often include:

  • multiple (>2) milia-like cysts
  • comedo-like openings
  • a network-like structure that corresponds to gyri and sulci and which in some cases can create a cerebriform pattern
  • fingerprint-like structures
  • moth-eaten borders
  • jelly sign. This consists of semicircular u-shaped structures that have a smudged appearance and are aligned in the same direction. The appearance resembles jelly as it is spread on a piece of bread.
  • hairpin (looped or twisted-looped) vessels surrounded by a white halo.

Seborrheic keratosis

Other clues include a sharp demarcation and a negative wobble sign (which we’ll describe in a moment). The presence or absence of a wobble sign is determined by using a dermatoscope that touches the skin. Mild vertical pressure is applied to the lesion while moving the scope back and forth horizontally. If the lesion slides across the skin surface, the diagnosis of an epidermal keratinocytic tumor (ie, SK) is favored. If, on the other hand, the lesion wobbles (rolls back and forth), then the diagnosis of a neoplasm with a dermal component (ie, intradermal or compound nevus) is more likely.

Angiomas and angiokeratomas. Angiomas demonstrate lacunae that are often separated by septae (FIGURE 6). Lacunae can vary in size and color. They can be red, red-white, red-blue, maroon, blue, blue-black, or even black (when thrombosis is present).

Angioma

Angiokeratomas (FIGURE 7) can reveal lacunae of varying colors including black, red, purple, and maroon. In addition, a blue-whitish veil, erythema, and hemorrhagic crusts can be present.

Angiokeratoma

Continue to: Sebaceous hyperplasia...

 

 

Sebaceous hyperplasia is the overgrowth of sebaceous glands. It can mimic BCC on the face. Sebaceous hyperplasia presents with multiple vessels in a crown-like arrangement that do not cross the center of the lesion. The sebaceous glands resemble popcorn (FIGURE 8).

Sebaceous hyperplasia

Clear-cell acanthoma is a benign erythematous epidermal tumor usually found on the leg with a string-of-pearls pattern. This pattern is vascular so the pearls are red in color (FIGURE 9).

Clear-cell acanthoma with string-of-pearls vessels

Malignant nonmelanocytic lesions

BCC is the most common type of skin cancer. Features often include:

  • spoke-wheel-like structures or concentric structures (FIGURE 10A)
  • leaf-like areas (FIGURE 10B)
  • arborizing vessels (FIGURE 10b and 10C)large blue-gray ovoid nest (FIGURE 10A)
  • multiple blue-gray non-aggregated globules
  • ulceration or multiple small erosions
  • shiny white structures and strands (FIGURE 10C).

Basal cell carcinomas

Additional dermoscopic clues include short, fine, superficial telangiectasias and multiple in-focus dots in a buck-shot scatter distribution.

Squamous cell carcinomas (SCCs) of the skin are keratinizing malignant tumors. Each SCC generally has some of the following features (FIGURE 11):

  • dotted and/or glomerular vessels, commonly distributed focally at the periphery. They can also be diffuse or aligned linearly within the lesion.
  • scale (yellow or white)
  • rosettes (seen with polarized light)
  • white circles or keratin pearls
  • brown circles
  • ulcerations
  • brown dots or globules arranged in a linear configuration.

Squamous cell carcinoma in situ with dotted vessels

Continue to: Step 2...

 

 

Step 2: It’s melanocytic, but is it a nevus or a melanoma?

If, by following Step 1 of the algorithm, the lesion is determined to be of melanocytic origin, then one proceeds to Step 2 to decide whether the growth is a nevus, a suspicious lesion, or a melanoma. For this purpose, several additional algorithms are available.12-17

Benign nevi patterns

Benign nevi tend to manifest with 1 of the following 10 patterns: (FIGURE 12)

  1. diffuse reticular
  2. patchy reticular
  3. peripheral reticular with central hypopigmentation
  4. peripheral reticular with central hyperpigmentation
  5. homogeneous
  6. peripheral globules/starburst. It has been suggested that lesions that show starburst morphology on dermoscopy require complete excision and follow-up since 13% of Spitzoid-looking symmetric lesions in patients older than 12 years were found to be melanoma in one study.18
  7. peripheral reticular with central globules
  8. globular
  9. 2-component
  10. symmetric multicomponent (this pattern should be interpreted with caution, and a biopsy is probably warranted for dermoscopic novices).

Melanoma-specific structures

Melanomas tend to deviate from the benign patterns described earlier. Structures in melanomas are often distributed in an asymmetric fashion (which is the basis for diagnosis in many of the other algorithms), and most of them will reveal 1 or more of the melanoma-specific structures (FIGURE 13). The melanomas in FIGURES 14 A-H each show at least 2 melanoma-specific structures. On the face or sun-damaged skin, melanoma may present with grey color, a circle-in-circle pattern, and/or polygonal lines (FIGURE 15). Note that melanoma on the soles or palms may present with a parallel ridge pattern (FIGURE 16).

Melanomas with melanoma-specific structures

How to proceed after the evaluation of melanocytic lesions

After evaluating the lesion for benign patterns and melanoma-specific structures, there are 3 possible pathways:

1. The lesion adheres to one of the nevi patterns and does not display a melanoma-specific structure. You can reassure the patient that the lesion is benign.

2. The lesion:

A. Adheres to one nevus pattern, but also displays a melanoma-specific structure.

B. Does not adhere to any of the benign patterns and does not have any melanoma-specific structures.

Lentigo maligna melanoma

This is considered a suspicious lesion, and the choices of action include performing a biopsy or short-term monitoring by comparing dermoscopic images over a 3-month interval. (Caveat: Never monitor raised lesions because nodular melanomas can grow quickly and develop a worsened prognosis in a short time. Instead you’ll want to biopsy the lesion that day or very soon thereafter.)

3. The lesion deviates from the benign patterns and has at least 1 melanoma-specific structure. Biopsy the lesion to rule out melanoma.

A bonus: Diagnosing scabies

Increasingly, dermoscopy is being used in the diagnosis of many other skin, nail, and hair problems. In fact, one great bonus to owning a dermatoscope is the accurate diagnosis of scabies. Dermoscopy can be helpful in detecting the scabies mite without having to scrape and use the microscope. Moreover, the sensitivity and specificity of a dermoscopic diagnosis is higher than for scraping and microscopy.19

What you’ll see

The anterior legs and mouth parts of the mite resemble a triangle (arrowhead, delta-wing jet) (FIGURE 17). Look for a burrow, and the mite can be seen at the end of the burrow as a faint circle with a leading darker triangle. The burrow itself has a distinctive pattern that has more morphology than an excoriation and has been described as the contrail of a jet plane. Using a dermatoscope attached to your smartphone allows you to magnify the image even further while maintaining a safe distance from the mite.

Dermoscopy, the use of a handheld instrument to magnify the skin 10-fold while providing a light source, is a quick, useful, cost-effective tool for detecting melanoma in family medicine.1-4 The device, which allows the physician to visualize structures below the stratum corneum that are not routinely discernible with the naked eye, can be attached to a smartphone so that photos can be taken and reviewed with the patient. The photo can also be reviewed after a biopsy result is obtained.

Its use among non-dermatologist US physicians appears to be relatively low, but rising. One small study of physicians working in family medicine, internal medicine, and plastic surgery found that only 15% had ever used a dermatoscope and 6% were currently using one.5

As a family physician, you can expand your diagnostic abilities in dermatology with the acquisition of a dermatoscope (FIGURE 1) and some time invested in learning to interpret visible patterns. With that in mind, this review focuses on the diagnosis of skin cancers and benign growths using dermoscopy. We begin with a brief look at the research on dermoscopy and how it is performed. From there, we’ll detail an algorithm to guide dermoscopic analysis. And to round things out, we provide guidance that will help you to get started. (See “Choosing a dermatoscope—and making the most of it,” and “To learn more about dermoscopy …”.)

Choosing a dermatoscope—and making the most of it

1. Consider acquiring a hybrid dermatoscope.

Nonpolarized dermatoscopes (NPDs) and polarized dermatoscopes (PDs) provide different but complementary information. PDs enable users to identify features such as vessels and shiny white structures that are highly indicative of skin cancer. Because PDs are highly sensitive for detecting skin cancer and do not require a liquid interface or direct skin contact, they are the ideal dermatoscopes to use for skin cancer screening.

However, maintaining the highest specificity requires the complementary use of NPDs, which are better at identifying surface structures seen in seborrheic keratoses and other benign lesions. Thus, if the aim is to maintain the highest diagnostic accuracy for all types of lesions, then the preferred dermatoscope is a hybrid that permits the user to toggle between polarized and nonpolarized features in one device.

2. Choose a dermatoscope that attaches to your smartphone and/or camera.

This helps you capture digital dermoscopic images that can be analyzed on a larger screen, which permits:

  • enlarging certain areas for in-depth analysis of structures and patterns
  • sharing the image with the patient to explain why a biopsy is, or isn’t, needed
  • sharing the image with a colleague for the purpose of a consult or a referral, or using the images for teaching purposes
  • saving the images in order to follow lesions over time when monitoring is indicated
  • ongoing learning. After each biopsy result comes back, we recommend correlating the dermoscopic images with the biopsy report. If your suspected diagnosis was correct, this reinforces your knowledge. If the pathology diagnosis is unexpected, you can learn by revisiting the original images to look for structures or patterns you may have missed upon first examination. You may even question the pathology report based on the dermoscopy, prompting a call to the pathologist.
  • keeping a safe distance from the patient when looking for scabies mites.

What the research says

Dermoscopy improves sensitivity for detecting melanoma over the naked eye alone; it also allows for the detection of melanoma at earlier stages, which improves prognosis.6

A meta-analysis of dermoscopy use in clinical settings showed that, following training, dermoscopy increases the average sensitivity of melanoma diagnosis from 71% to more than 90% without a significant decrease in specificity.7 In a study of 74 primary care physicians, there was an improvement in both clinical and dermoscopic diagnosis of melanoma among those who received training in dermoscopy, compared with a control group.8 Another study found that primary care physicians can reduce their baseline benign-to-melanoma ratio (the number of suspicious benign lesions biopsied to find 1 melanoma) from 9.5:1 with naked eye examination to 3.5:1 with dermoscopy.9

The exam begins by choosing 1 of 3 modes of dermoscopy

Dermatoscopes can have a polarized or nonpolarized light source. Some dermatoscopes combine both types of light (hybrid dermatoscopes; see “Choosing a dermatoscope—and making the most of it.”)

There are 3 modes of dermoscopy:

  1. nonpolarized contact dermoscopy
  2. polarized contact dermoscopy
  3. polarized non-contact dermoscopy.

Dermatoscopes with nonpolarized light require direct skin contact and a liquid interface (eg, alcohol, gel, mineral oil) between the scope’s glass plate and the skin for the visualization of subsurface structures. In contrast, dermatoscopes with polarized light do not require direct skin contact or a liquid interface; however, contacting the skin and using a liquid interface will provide a sharper image.

Two major algorithms guide dermoscopic analysis

The first of 2 major algorithms that can be used to guide dermoscopic analysis is a modified pattern analysis put forth by Kittler.10 This descriptive system based on geometric elements, patterns, colors, and clues guides the observer to a specific diagnosis without categorizing lesions as being either melanocytic or nonmelanocytic. Because this is not the preferred method of the authors, we will move on to Method 2.

The second method, a 2-step algorithm, is a qualitative system that guides the observer through differentiating melanocytic from nonmelanocytic lesions in order to differentiate nevi from melanoma (FIGURE 2). At the same time, it serves as an aid to correctly diagnose non-melanocytic lesions. The 2-step algorithm forms the foundation for the dermoscopic evaluation of skin lesions in this article.

A 2-step algorithm for dermatoscopic diagnosis of skin lesions

Not all expert dermoscopists employ structured analytical systems or methods to reach a diagnosis. Because of their vast experience, many rely purely on pattern recognition. But algorithms can facilitate non-experts in dermoscopy in the differentiation of nevi from melanoma or, simply, in differentiating the benign from the malignant.

Although each algorithm has its unique criteria, all of them require training and practice and familiarity with the terms used to describe morphologic structures. The International Dermoscopy Society recently published a consensus paper designating some terms as preferred over others.11

Continue to: Step 1...

 

 

Step 1: Melanocytic vs non-melanocytic

Step 1 of the 2-step algorithm requires the observer to determine whether the lesion is melanocytic (ie, originates from melanocytes and, therefore, could be a melanoma) or nonmelanocytic in origin.

A melanocytic lesion usually will display at least 1 of the following structures:

  • pigment network (FIGURE 3A) (This can include angulated lines.)
  • negative network (FIGURE 3B) (hypopigmented lines connecting pigmented structures in a serpiginous fashion)
  • streaks (FIGURE 3C)
  • homogeneous blue pigmentation (FIGURE 3D)
  • globules (aggregated or as a peripheral rim) (FIGURE 3E)
  • pseudonetwork (facial skin) (FIGURE 3F)
  • parallel pigment pattern (acral lesions) (FIGURE 3G).

Features of melanocytic lesions

Exceptions. Sometimes, nonmelanocytic lesions will present with pigment network. Dermatofibromas, for example, are one exception in which the pattern trumps the network. Two other exceptions are solar lentigo and supernumerary or accessory nipple.

If the lesion does not display any structure, it is considered structureless. In these cases, proceed to the second step to rule out a melanoma.

Doesn’t meet criteria for a melanocytic lesion?

If the lesion does not reveal any of the criteria for a melanocytic lesion, then look for structures seen in nonmelanocytic lesions: dermatofibromas; seborrheic keratosis; angiomas and angiokeratomas; sebaceous hyperplasia; clear-cell acanthomas; basal cell carcinomas (BCCs); and squamous cell carcinomas (SCCs).

Continue to: Benign nonmelanocytic lesions

 

 

Benign nonmelanocytic lesions

Dermatofibromas are benign symmetric lesions that feel firm and may dimple upon application of lateral pressure. They are fibrotic scar-like lesions that present with 1 or more of the following dermoscopic features (FIGURE 4):

  • peripheral pigment network, due to increased melanin in keratinocytes
  • homogeneous brown pigmented areas
  • central scar-like area
  • shiny white lines
  • vascular structures (ie, dotted, polymorphous vessels), usually seen within the scar-like area
  • ring-like globules, usually seen in the zone between the scar-like depigmentation and the peripheral network. They correspond to widened hyperpigmented rete ridges.

A dermatofibroma

Seborrheic keratosis (SK) is a benign skin growth that often has a stuck-on appearance (FIGURE 5). Features often include:

  • multiple (>2) milia-like cysts
  • comedo-like openings
  • a network-like structure that corresponds to gyri and sulci and which in some cases can create a cerebriform pattern
  • fingerprint-like structures
  • moth-eaten borders
  • jelly sign. This consists of semicircular u-shaped structures that have a smudged appearance and are aligned in the same direction. The appearance resembles jelly as it is spread on a piece of bread.
  • hairpin (looped or twisted-looped) vessels surrounded by a white halo.

Seborrheic keratosis

Other clues include a sharp demarcation and a negative wobble sign (which we’ll describe in a moment). The presence or absence of a wobble sign is determined by using a dermatoscope that touches the skin. Mild vertical pressure is applied to the lesion while moving the scope back and forth horizontally. If the lesion slides across the skin surface, the diagnosis of an epidermal keratinocytic tumor (ie, SK) is favored. If, on the other hand, the lesion wobbles (rolls back and forth), then the diagnosis of a neoplasm with a dermal component (ie, intradermal or compound nevus) is more likely.

Angiomas and angiokeratomas. Angiomas demonstrate lacunae that are often separated by septae (FIGURE 6). Lacunae can vary in size and color. They can be red, red-white, red-blue, maroon, blue, blue-black, or even black (when thrombosis is present).

Angioma

Angiokeratomas (FIGURE 7) can reveal lacunae of varying colors including black, red, purple, and maroon. In addition, a blue-whitish veil, erythema, and hemorrhagic crusts can be present.

Angiokeratoma

Continue to: Sebaceous hyperplasia...

 

 

Sebaceous hyperplasia is the overgrowth of sebaceous glands. It can mimic BCC on the face. Sebaceous hyperplasia presents with multiple vessels in a crown-like arrangement that do not cross the center of the lesion. The sebaceous glands resemble popcorn (FIGURE 8).

Sebaceous hyperplasia

Clear-cell acanthoma is a benign erythematous epidermal tumor usually found on the leg with a string-of-pearls pattern. This pattern is vascular so the pearls are red in color (FIGURE 9).

Clear-cell acanthoma with string-of-pearls vessels

Malignant nonmelanocytic lesions

BCC is the most common type of skin cancer. Features often include:

  • spoke-wheel-like structures or concentric structures (FIGURE 10A)
  • leaf-like areas (FIGURE 10B)
  • arborizing vessels (FIGURE 10b and 10C)large blue-gray ovoid nest (FIGURE 10A)
  • multiple blue-gray non-aggregated globules
  • ulceration or multiple small erosions
  • shiny white structures and strands (FIGURE 10C).

Basal cell carcinomas

Additional dermoscopic clues include short, fine, superficial telangiectasias and multiple in-focus dots in a buck-shot scatter distribution.

Squamous cell carcinomas (SCCs) of the skin are keratinizing malignant tumors. Each SCC generally has some of the following features (FIGURE 11):

  • dotted and/or glomerular vessels, commonly distributed focally at the periphery. They can also be diffuse or aligned linearly within the lesion.
  • scale (yellow or white)
  • rosettes (seen with polarized light)
  • white circles or keratin pearls
  • brown circles
  • ulcerations
  • brown dots or globules arranged in a linear configuration.

Squamous cell carcinoma in situ with dotted vessels

Continue to: Step 2...

 

 

Step 2: It’s melanocytic, but is it a nevus or a melanoma?

If, by following Step 1 of the algorithm, the lesion is determined to be of melanocytic origin, then one proceeds to Step 2 to decide whether the growth is a nevus, a suspicious lesion, or a melanoma. For this purpose, several additional algorithms are available.12-17

Benign nevi patterns

Benign nevi tend to manifest with 1 of the following 10 patterns: (FIGURE 12)

  1. diffuse reticular
  2. patchy reticular
  3. peripheral reticular with central hypopigmentation
  4. peripheral reticular with central hyperpigmentation
  5. homogeneous
  6. peripheral globules/starburst. It has been suggested that lesions that show starburst morphology on dermoscopy require complete excision and follow-up since 13% of Spitzoid-looking symmetric lesions in patients older than 12 years were found to be melanoma in one study.18
  7. peripheral reticular with central globules
  8. globular
  9. 2-component
  10. symmetric multicomponent (this pattern should be interpreted with caution, and a biopsy is probably warranted for dermoscopic novices).

Melanoma-specific structures

Melanomas tend to deviate from the benign patterns described earlier. Structures in melanomas are often distributed in an asymmetric fashion (which is the basis for diagnosis in many of the other algorithms), and most of them will reveal 1 or more of the melanoma-specific structures (FIGURE 13). The melanomas in FIGURES 14 A-H each show at least 2 melanoma-specific structures. On the face or sun-damaged skin, melanoma may present with grey color, a circle-in-circle pattern, and/or polygonal lines (FIGURE 15). Note that melanoma on the soles or palms may present with a parallel ridge pattern (FIGURE 16).

Melanomas with melanoma-specific structures

How to proceed after the evaluation of melanocytic lesions

After evaluating the lesion for benign patterns and melanoma-specific structures, there are 3 possible pathways:

1. The lesion adheres to one of the nevi patterns and does not display a melanoma-specific structure. You can reassure the patient that the lesion is benign.

2. The lesion:

A. Adheres to one nevus pattern, but also displays a melanoma-specific structure.

B. Does not adhere to any of the benign patterns and does not have any melanoma-specific structures.

Lentigo maligna melanoma

This is considered a suspicious lesion, and the choices of action include performing a biopsy or short-term monitoring by comparing dermoscopic images over a 3-month interval. (Caveat: Never monitor raised lesions because nodular melanomas can grow quickly and develop a worsened prognosis in a short time. Instead you’ll want to biopsy the lesion that day or very soon thereafter.)

3. The lesion deviates from the benign patterns and has at least 1 melanoma-specific structure. Biopsy the lesion to rule out melanoma.

A bonus: Diagnosing scabies

Increasingly, dermoscopy is being used in the diagnosis of many other skin, nail, and hair problems. In fact, one great bonus to owning a dermatoscope is the accurate diagnosis of scabies. Dermoscopy can be helpful in detecting the scabies mite without having to scrape and use the microscope. Moreover, the sensitivity and specificity of a dermoscopic diagnosis is higher than for scraping and microscopy.19

What you’ll see

The anterior legs and mouth parts of the mite resemble a triangle (arrowhead, delta-wing jet) (FIGURE 17). Look for a burrow, and the mite can be seen at the end of the burrow as a faint circle with a leading darker triangle. The burrow itself has a distinctive pattern that has more morphology than an excoriation and has been described as the contrail of a jet plane. Using a dermatoscope attached to your smartphone allows you to magnify the image even further while maintaining a safe distance from the mite.

If the lesion slides across the skin surface, the diagnosis of an epidermal keratinocytic tumor (ie, SK) is favored. If, on the other hand, the lesion wobbles (rolls back and forth), then the diagnosis of a neoplasm with a dermal component (ie, intradermal or compound nevus) is more likely.

Angiomas and angiokeratomas. Angiomas demonstrate lacunae that are often separated by septae (FIGURE 6). Lacunae can vary in size and color. They can be red, red-white, red-blue, maroon, blue, blue-black, or even black (when thrombosis is present).

Angioma

Angiokeratomas (FIGURE 7) can reveal lacunae of varying colors including black, red, purple, and maroon. In addition, a blue-whitish veil, erythema, and hemorrhagic crusts can be present.

Angiokeratoma

Continue to: Sebaceous hyperplasia...

 

 

Sebaceous hyperplasia is the overgrowth of sebaceous glands. It can mimic BCC on the face. Sebaceous hyperplasia presents with multiple vessels in a crown-like arrangement that do not cross the center of the lesion. The sebaceous glands resemble popcorn (FIGURE 8).

Sebaceous hyperplasia

Clear-cell acanthoma is a benign erythematous epidermal tumor usually found on the leg with a string-of-pearls pattern. This pattern is vascular so the pearls are red in color (FIGURE 9).

Malignant nonmelanocytic lesions

BCC is the most common type of skin cancer. Features often include:

  • spoke-wheel-like structures or concentric structures (FIGURE 10A)
  • leaf-like areas (FIGURE 10B)
  • arborizing vessels (FIGURE 10b and 10C)large blue-gray ovoid nest (FIGURE 10A)
  • multiple blue-gray non-aggregated globules
  • ulceration or multiple small erosions
  • shiny white structures and strands (FIGURE 10C).

Basal cell carcinomas

Additional dermoscopic clues include short, fine, superficial telangiectasias and multiple in-focus dots in a buck-shot scatter distribution.

Squamous cell carcinomas (SCCs) of the skin are keratinizing malignant tumors. Each SCC generally has some of the following features (FIGURE 11):

  • dotted and/or glomerular vessels, commonly distributed focally at the periphery. They can also be diffuse or aligned linearly within the lesion.
  • scale (yellow or white)
  • rosettes (seen with polarized light)
  • white circles or keratin pearls
  • brown circles
  • ulcerations
  • brown dots or globules arranged in a linear configuration.

Continue to: Step 2...

 

 

Step 2: It’s melanocytic, but is it a nevus or a melanoma?

If, by following Step 1 of the algorithm, the lesion is determined to be of melanocytic origin, then one proceeds to Step 2 to decide whether the growth is a nevus, a suspicious lesion, or a melanoma. For this purpose, several additional algorithms are available.12-17

Benign nevi patterns

Benign nevi tend to manifest with 1 of the following 10 patterns: (FIGURE 12)

  1. diffuse reticular
  2. patchy reticular
  3. peripheral reticular with central hypopigmentation
  4. peripheral reticular with central hyperpigmentation
  5. homogeneous
  6. peripheral globules/starburst. It has been suggested that lesions that show starburst morphology on dermoscopy require complete excision and follow-up since 13% of Spitzoid-looking symmetric lesions in patients older than 12 years were found to be melanoma in one study.18
  7. peripheral reticular with central globules
  8. globular
  9. 2-component
  10. symmetric multicomponent (this pattern should be interpreted with caution, and a biopsy is probably warranted for dermoscopic novices).

Melanoma-specific structures

Melanomas tend to deviate from the benign patterns described earlier. Structures in melanomas are often distributed in an asymmetric fashion (which is the basis for diagnosis in many of the other algorithms), and most of them will reveal 1 or more of the melanoma-specific structures (FIGURE 13). The melanomas in FIGURES 14 A-H each show at least 2 melanoma-specific structures. On the face or sun-damaged skin, melanoma may present with grey color, a circle-in-circle pattern, and/or polygonal lines (FIGURE 15). Note that melanoma on the soles or palms may present with a parallel ridge pattern (FIGURE 16).

Melanomas with melanoma-specific structures

How to proceed after the evaluation of melanocytic lesions

After evaluating the lesion for benign patterns and melanoma-specific structures, there are 3 possible pathways:

1. The lesion adheres to one of the nevi patterns and does not display a melanoma-specific structure. You can reassure the patient that the lesion is benign.

2. The lesion:

A. Adheres to one nevus pattern, but also displays a melanoma-specific structure.

B. Does not adhere to any of the benign patterns and does not have any melanoma-specific structures.

Lentigo maligna melanoma

This is considered a suspicious lesion, and the choices of action include performing a biopsy or short-term monitoring by comparing dermoscopic images over a 3-month interval. (Caveat: Never monitor raised lesions because nodular melanomas can grow quickly and develop a worsened prognosis in a short time. Instead you’ll want to biopsy the lesion that day or very soon thereafter.)

3. The lesion deviates from the benign patterns and has at least 1 melanoma-specific structure. Biopsy the lesion to rule out melanoma.

A bonus: Diagnosing scabies

Increasingly, dermoscopy is being used in the diagnosis of many other skin, nail, and hair problems. In fact, one great bonus to owning a dermatoscope is the accurate diagnosis of scabies. Dermoscopy can be helpful in detecting the scabies mite without having to scrape and use the microscope. Moreover, the sensitivity and specificity of a dermoscopic diagnosis is higher than for scraping and microscopy.19

What you’ll see

The anterior legs and mouth parts of the mite resemble a triangle (arrowhead, delta-wing jet) (FIGURE 17). Look for a burrow, and the mite can be seen at the end of the burrow as a faint circle with a leading darker triangle. The burrow itself has a distinctive pattern that has more morphology than an excoriation and has been described as the contrail of a jet plane. Using a dermatoscope attached to your smartphone allows you to magnify the image even further while maintaining a safe distance from the mite.

Phase 3 study confirms biosimilarity of PF-05280586 with rituximab

Article Type

Tue, 01/17/2023 - 11:16

– The potential rituximab biosimilar drug PF-05280586 showed efficacy, safety, immunogenicity, pharmacokinetics, and pharmacodynamics similar to those of rituximab at up to 26 weeks in a randomized phase 3 study of treatment-naive patients with CD20-positive low tumor burden follicular lymphoma (LTB-FL).

Sharon Worcester/MDedge News
Dr. Jeff Sharman

The primary endpoint of overall response rate at 26 weeks was 75.5% in 196 patients randomized to receive PF-05280586, and 70.7% in 198 patients who received a rituximab reference product sourced from the European Union (MabThera; rituximab‑EU), Jeff Sharman, MD, reported at the annual meeting of the American Society of Hematology.

“This resulted in a difference between the two arms of 4.66%,” said Dr. Sharman of Willamette Valley Cancer Institute and Research Center, Springfield, Ore.

The 95% confidence interval for this difference ... was entirely contained within the prespecified equivalence margin, he said.

“Depth of response was a key secondary endpoint, and rates of complete response were 29.3% and 30.4%, respectively,” he said, noting that rates of partial response, stable response, and progressive disease were also similar between the two study arms.

Estimated 1-year progression-free survival (PFS) rates were also highly similar at 76.4% and 81.2% in the PF-05280586 and rituximab-EU arms.


Rapid depletion in CD19-positive B-cell counts was observed in both groups after initial dosing, with recovery by week 39 and a sustained increase until the end of week 52.

Treatment-emergent adverse events (TEAEs) occurred in 78.6% vs. 72.1% of patients in the PF‑05280586 vs. rituximab‑EU arms, respectively, and the rates of serious adverse events and grade 3 events were similar in the groups, as were rates of infusion interruptions or infusion-related reactions (IRRs), Dr. Sharman said.

IRRs occurred in about 25% of patients in each arm, and most were grade 1 or 2. Grade 3 IRRs occurred in 2.6% vs. 0.5% of patients in the groups, respectively, and no grade 4 IRRs occurred.

Rates of anti-drug antibodies were also similar in the two groups, as were serum drug concentrations – regardless of anti-drug antibody status, he noted.

Study subjects were adults with a mean age of 60 years and histologically confirmed CD20-positive grade 1-3a follicular lymphoma with no prior rituximab or system therapy for B-cell non-Hodgkin lymphoma (NHL). They had Ann Arbor disease stages II (26.9%), III (44.2%) or IV (28.9%), ECOG performance status of 0-1, and at least 1 measurable disease lesion identifiable on imaging.

Risk level as assessed by the Follicular Lymphoma International Prognostic Index–2 was low in 28.4%, medium in 66%, and high in 5.6% of patients.

Treatment with each agent was given at intravenous doses of 375 mg/m2 weekly for 4 weeks at days 1, 8, 15, and 22.

PF-05280586 is being developed by Pfizer, and in this 52-week double-blind study – the largest study to date of the early use of the potential rituximab biosimilar in patients with previously untreated CD20-positive LTB-FL – the primary endpoint was met, demonstrating its therapeutic equivalence with rituximab-EU for overall response rate at week 26, Dr. Sharman said.

“These results therefore confirm the biosimilarity of PF-05280586 with rituximab-EU,” he concluded.

Of note, the reporting of these findings comes on the heels of the first Food and Drug Administration approval of a biosimilar rituximab product for the treatment of NHL; Celltrion’s product Truxima (formerly CT-P10), a biosimilar of Genentech’s Rituxan (rituximab), was approved Nov. 28 to treat adults with CD20-positive, B-cell NHL, either as a single agent or in combination with chemotherapy.

The PF-0528056 study was sponsored by Pfizer. Dr. Sharman has been a consultant for, and/or received research funding and honoraria from Acerta, Pharmacyclics (an AbbVie Company), Pfizer, TG Therapeutics, Abbvie, and Genentech.

Factor IX expression stable at up to 8 years with gene therapy

Article Type

Therapeutic expression of factor IX remains stable with no late toxicities occurring at up to 8.6 years after a single infusion of a novel gene therapy in patients with severe hemophilia B, according to interim follow-up data from a phase 1/2 dose-escalation study.

The therapy – a self-complementary adeno-associated virus vector containing a codon-optimized factor IX gene, under control of a synthetic liver specific promoter and pseudotyped with serotype 8 capsid (scAAV2/8-LP1-hFIXco) – was previously shown to result in a dose-dependent increase in plasma factor IX levels in all 10 patients enrolled in the study, and an earlier update showed stable factor IX activity for at least 3 years, Ulrike M. Reiss, MD, reported at the annual meeting of the American Society of Hematology.

However, declining factor IX expression over time remains a concern, because AAV-mediated transgene expression is mediated mainly by episomally retained viral genomes, which may be lost with natural turnover of hepatocytes, noted Dr. Reiss, director of the clinical hematology division and the Hemophilia Treatment Center at St. Jude Children’s Research Hospital in Memphis.

At the “halfway mark,” with a median follow-up of 6.7 years in 10 patients aged 18-64 years who were treated with doses of either 2 x 1011, 6 x 1011, or 2 x 1012 vector genomes per kg (in 2, 2, and 6 patients, respectively), “factor IX expression has been persistent and stable in all participants after vector infusion,” she said.

“Factor IX expression was vector-dose dependent, achieving average levels of 1.9%-2.3% at the lower doses, and 5.1% at the high vector dose. All patients converted from having severe hemophilia to mild-moderate hemophilia,” she added.

The single significant adverse event observed during annual follow-up evaluations in the patients was a vector-related, immune-mediated liver inflammation occurring within 2-3 months of infusion in four of the six high-dose participants.

“There was complete resolution in all cases after a short course of corticosteroids over 8-12 weeks, including the taper. There were no late sequelae or any recurrence of transaminitis over time,” Dr. Reiss said. “We did not observe any new factor IX inhibitor or any late toxicity in any of these participants.”



Additionally, a comparison of average data across 3 years prior to gene therapy with the average data at 6.7 years after gene therapy showed that the annualized bleed rate decreased by 82% in the 10 participants and factor IX use decreased by 66%. In the high-dose group, the bleed rate decreased from 21 bleeds to 2 bleeds per year, and vector consumption was markedly reduced to a mean of 500 IU/kg per year from a mean of more than 2800 IU/kg per year. “Only one of the six patients in the high-dose group currently continues on prophylaxis treatment, whereas three in the low- and mid-dose groups are currently on prophylaxis,” she said. “In all [patients], the interval between prophylactic infusions has lengthened.”

Of note, Dr. Reiss and her colleagues explored the ability of using a modified, empty capsid-reduced vector preparation of the gene therapy to prevent the transaminitis seen in the 2-3 months after infusion. A new clinical preparation of scAAV2/8-LP1-hFIXco was manufactured with most of the empty particles removed by cesium chloride density centrifugation, but this approach provided no benefit in that regard.

“This further supports the observation that the anticapsid immune response is vector-dose dependent,” she said.

Additionally, the pattern of humoral response to AAV8 capsid was consistent with the primary immune response in participants.

“High IgG antibody titers have persisted for over 6 years; this finding is important because it will preclude these patients from any retreatment with the same vector or even potentially alternative AAV vectors of other serotypes with cross-reactive antigenicity,” she said.

Therapeutic expression of factor IX remains stable with no late toxicities occurring at up to 8.6 years after a single infusion of a novel gene therapy in patients with severe hemophilia B, according to interim follow-up data from a phase 1/2 dose-escalation study.

Similarity of CT-P6 and trastuzumab remain with longer follow-up

After a 2-year follow-up, the efficacy and cardiac toxicity profile between CT-P6, a trastuzumab biosimilar candidate, and trastuzumab as neoadjuvant and then adjuvant therapy for patients with early HER2-positive breast cancer remains consistent with previous results.

Similarity in safety and efficacy at 1 year was previously demonstrated in the phase 3 trial, as well as similarity in cardiac toxicity at a median of 19 months. Updated disease-free survival, overall survival, and cardiac toxicity with a median follow-up of 2 years will be presented by Francisco J. Esteva, MD, PhD, of the Laura & Isaac Perlmutter Cancer Center at NYU Langone Health, New York, in a poster presentation at the San Antonio Breast Cancer Symposium.

For the trial, 549 patients with HER2-positive early breast cancer were randomized to receive CT-P6 (n = 271) or trastuzumab (n = 278) in combination with docetaxel (cycles 1-4) and 5-fluorouracil, epirubicin, and cyclophosphamide (cycles 5-8). CT-P6 or trastuzumab was administered at 8 mg/kg (cycle 1 only) followed by 6 mg/kg every 3 weeks. After surgery, patients received CT-P6 or trastuzumab monotherapy and then entered the follow-up period.

A total of 528 patients entered the follow-up period, with a median duration of 27 months. Disease-free and overall survival were similar in the two arms in both the per-protocol set and the intention-to-treat set. In the intention-to-treat set, the 2-year disease-free survival was 86% (95% confidence interval, 80%-90%) in the CT-P6 arm and 90% (95% CI, 85%-93%) in the trastuzumab arm. Two-year overall survival was 97% (95% CI, 93%-98%) in the CT-P6 arm and 98% (95% CI, 96%-99%) in the trastuzumab arm. Median disease-free and overall survival have not been reached, according to the abstract.

No new cases of heart failure were reported during the follow-up period. Left ventricular ejection fraction was similar in both arms. The efficacy and cardiac toxicity profile between CT-P6 and trastuzumab were consistent with published data.

“CT-P6 was consistently well tolerated with a similar cardiotoxicity profile to that of trastuzumab through a long duration of follow-up,” Dr. Esteva and authors said.

The study sponsor is Celltrion, maker of CT-P6. Dr. Esteva disclosed a consulting or advisory role with Celltrion, as well as relationships with various other pharmaceutical companies.

PAD guidelines: Consensus needed between U.S. and Europe

Article Type
Changed
Sat, 12/08/2018 - 15:32

 

Recent advances in the management of peripheral artery disease (PAD) have resulted in new guideline creation in both the United States and Europe.

Vizualis/Thinkstock

While there is considerable consensus between the guidelines, there are multiple differences in emphasis and a differing approach to the types and quality of evidence used to back recommendations, according to a comparative review published in the Journal of the American College of Cardiology. The American Heart Association and American College of Cardiology, together with other organizations, issued an update to their previous guidelines on the management and diagnosis of lower extremity PAD in 2016. In 2017, the European Society of Cardiology in conjunction with the European Society for Vascular Surgery updated their own comprehensive guidelines.

Both the U.S. and the European guidelines stress the importance of lowering risk factors for PAD. This includes stopping smoking, lipid and blood pressure management, and controlling glucose, according to Aaron P. Kithcart, MD, of Brigham and Women’s Hospital, Boston, and Joshua A. Beckman, MD, of Vanderbilt University, Nashville, Tenn.

However, the U.S. guidelines focus more on moderating lifestyle factors, including the pursuit of regular physical activity and the use of supervised exercise, whereas the European guidelines focus considerable attention on recommendations for revascularization in patients with limb-threatening ischemia.

Perhaps the major source of variation between the two sets of guidelines, according to the reviewers, are based upon the intended audiences: “The American document limits its focus to PAD but is applicable to practitioners of every background, whereas the European guideline extends the discussion to all PADs to include carotid and vertebral, upper extremities, mesenteric, and renal arteries in addition to lower-extremity artery disease; but is designed to be a source for cardiologists.”

Accordingly, the ESC/ESVS guidelines approach medical therapy with a more holistic flavor, whereas the ACC/AHA guidelines are specific to the lower-extremity complications of atherosclerosis, according to the reviewers.

Both sets of guidelines come to the conclusion that there is a need for more evidence to identify patients who are at the greatest risk of tissue loss, but overall they differ in their approach to available data. The ACC/AHA is more inclusive of smaller, well-done nonrandomized studies, whereas the ESC/ESVS relegates small studies to Level of Evidence: C. “We believe this difference drives the variation of therapeutic recommendations more than any other factor,” the authors note.

More randomized studies would align recommendations across both organizations, according to Dr. Kithcart and Dr. Beckman (JACC 2018;72:2789-801).

“The management of PAD has progressed a great deal over the last decade. ... Several clinical trials over the coming years should help clarify how revascularization should be approached, and which patients are most likely to benefit. Until then, maintaining good cardiovascular health, including regular physical activity, smoking cessation, lipid-lowering therapy, blood pressure management, and glucose control have the most benefit in patients with PAD,” the researchers concluded.

Dr. Beckman served as a consultant for several pharmaceutical companies, and on the data and safety monitoring board for Bayer and Novartis. Dr. Kithcart reported that he has no relevant conflicts.
