NEW YORK — New treatments for acne, including the recent FDA approval of a topical gel that combines an antibiotic, a retinoid, and an antimicrobial agent, and reports on the safe use of lasers in people with darker skin types, were presented at the annual Mount Sinai Winter Symposium – Advances in Medical and Surgical Dermatology.

Also highlighted were recommendations regarding antibiotic stewardship and consideration of a treatment’s beneficial effects beyond 12 weeks.

“Patients want clear skin and many don’t care how they get there. I see patients who have been on minocycline [a broad-spectrum antibiotic] for 2 years; this is really not the best way to treat our patients,” said Joshua Zeichner, MD, associate professor of dermatology at the Icahn School of Medicine at Mount Sinai Hospital, New York, who reviewed the current state of acne treatments at the meeting.

Patients often do not care about the risk of developing antibiotic resistance, he noted, citing a survey (funded by Almirall and presented at a previous conference), which found that less than 10% of adult patients or caregivers of patients being treated for acne were moderately or extremely worried about antibiotics compared with more than 65% of the clinicians. But despite their concerns, nearly 60% of clinicians surveyed reported prescribing broad-spectrum antibiotics “most” or “all of the time,” he said.

Dr. Zeichner said that patients’ short-term wishes overriding dermatologists’ own concerns can lead to antibiotic resistance, with a negative impact on patients’ microbiomes. He encouraged prescribers to incorporate sarecycline and other narrow spectrum antibiotics into their practice as part of antibiotic stewardship. These drugs have less of an impact on the gut microbiome than broad spectrum antibiotics, while targeting the patient’s acne.

Dr. Zeichner noted that “acne is more than a 12-week disease,” but manufacturers of acne treatments can only market information based on what is in the product labeling, which usually includes 12-week results. Yet, for many acne treatments, “as you continue treating over time, you’re seeing much better improvements,” he said.

As an example, he referred to data from an unpublished phase 4 Galderma study. Patients aged 17-35 years with acne and scarring who were treated with trifarotene cream demonstrated about a 52% rate of success in acne clearance as measured by the Investigator Global Assessment (IGA) at 24 weeks, up from 31.4% at 12 weeks, highlighting the need to consider long-term data, which is helpful for patients to know, he said.

Dr. Zeichner noted that many patients and their caregivers are enthusiastic about the idea of treatment that does not involve pharmaceuticals and that these options, while not “silver bullets,” are available and advancing.

These include light-based devices. He referred to a 7-week, open label efficacy and safety study of a photo-pneumatic device with broadband light (Strata Skin Sciences). This device uses thermal heat to target and destroy Cutibacterium acnes and reduce sebum production and has a vacuum feature that removes occlusive material from the pilosebaceous unit, which he said “leads directly to a reduction in acne lesions.”

Of note is the fact that the device’ filters out visible wavelength light, which minimizes absorption by melanin in the epidermis that can damage darker skin, making the treatment safe for most skin types. In the study of patients with mild to moderate facial acne, aged 12-40 years, treatment resulted in significant reductions in mean inflammatory and noninflammatory lesion counts, and mean IGA score at day 49 compared with baseline.

Similarly, Dr. Zeichner presented a 2022 study demonstrating the use of higher spectrum lasers (a 1726-nm [nanometer] laser) to shrink sebaceous glands and reduce sebum production to treat acne. In addition, lasers that operate at such a high frequency do not cause hyperpigmentation in individuals with darker skin types, he said.

Dr. Zeichner disclosed that he is an advisor, consultant, or speaker for AbbVie, Allergan, Arcutis, Beiersdorf, Dermavant, Galderma, Kenvue, L’Oreal, Ortho, Pfizer, Regeneron, UCB, and Sun.

TOPLINE: 

National survey data reveal an association between higher serum oleic acid levels and depression in adults, new research shows. 

METHODOLOGY:

Oleic acid is the most abundant fatty acid in plasma and has been associated with multiple neurologic diseases. However, the relationship between oleic acid and depression is unclear. 

This cross-sectional analyzed data on 4459 adults from the 2011-2014 National Health and Nutrition Examination Survey (NHANES).

Multivariable logistic regression models adjusting for demographics, health and lifestyle factors quantified the association between oleic acid levels and depression. Depression was assessed using the Patient Health Questionnaire-9 (PHQ-9) with depression defined as a score ≥ 10.

TAKEAWAY:

Serum oleic acid levels were positively associated with depression before and after multivariable adjustment.

After adjusting for all covariates, for every 1 mmol/L increase in serum oleic acid levels, the prevalence of depression increased by 40% (adjusted odds ratio [aOR], 1.40; 95% CI, 1.03-1.90). 

Adults in the top quartile of oleic acid (≥ 2.51 mmol/L) had a greater than twofold higher likelihood of depression (aOR, 2.22; 95% CI, 1.04-4.73) compared with peers in the lowest quartile (≤ 1.54 mmol/L). 

IN PRACTICE:

“A better understanding of the role of oleic acid in depression may lead to new preventive and therapeutic methods. Thus, carefully designed prospective studies are necessary to explore the positive effects of changing serum oleic acid levels through diet, medicine, or other measures on depression,” the authors write. 

SOURCE:

The study, with first author Jiahui Yin of Shandong University of Traditional Chinese Medicine in Jinan, China, was published online on November 16, 2023 in BMC Psychiatry .

LIMITATIONS: 

The cross-sectional study can’t prove causality. The findings may not apply to clinically diagnosed major depressive disorder. 

DISCLOSURES:

The study had no specific funding. The authors report no conflicts of interest.

Our psychiatric research, which found a high incidence of undiagnosed mental illness in mass shooters, was recently awarded the esteemed Psychodynamic Psychiatry Journal Prize for best paper published in the last 2 years (2022-2023). The editors noted our integrity in using quantitative data to argue against the common, careless assumption that mass shooters are not mentally ill.

Some of the mass shooters we studied were motivated by religious or political ideologies that were considered forms of terrorism. Given the current tragically violent landscape both at home and in Israel/Palestine, the “desire for destruction” is vital to understand.

Although there have been a limited number of psychiatric studies of perpetrators of mass shootings, our team took the first step to lay the groundwork by conducting a systematic, quantitative study. Our psychiatric research team’s research findings were published in the Journal of Clinical Psychopharmacology and then in greater detail in Psychodynamic Psychiatry,^1,2 which provided important context to the complicated backgrounds of these mass shooters who suffer from abuse, marginalization, and severe undiagnosed brain illness.³

Dr. Cerfolio

The Mother Jones database of 115 mass shootings from 1982 to 2019 was used to study retrospectively 55 shooters in the United States. We developed a uniform, comprehensive, 62-item questionnaire to compile the data collection from multiple sources and record our psychiatric assessments of the assailants, using DSM-5 criteria. After developing this detailed psychiatric assessment questionnaire, psychiatric researchers evaluated the weight and quality of clinical evidence by (1) interviewing forensic psychiatrists who had assessed the assailant following the crime, and/or (2) reviewing court records of psychiatric evaluations conducted during the postcrime judicial proceedings to determine the prevalence of psychiatric illness. Rather than accepting diagnoses from forensic psychiatrists and/or court records, our team independently reviewed the clinical data gathered from multiple sources to apply the DSM-5 criteria to diagnose mental illness.

In most incidents in the database, the perpetrator died either during or shortly after the crime. We examined every case (n=35) in which the assailant survived, and criminal proceedings were instituted.

Of the 35 cases in which the assailant survived and criminal proceedings were instituted, there was insufficient information to make a diagnosis in 3 cases. Of the remaining 32 cases in which we had sufficient information, we determined that 87.5% had the following psychiatric diagnosis: 18 assailants (56%) had schizophrenia, while 10 assailants (31%) had other psychiatric diagnoses: 3 had bipolar I disorder, 2 had delusional disorders (persecutory), 2 had personality disorders (1 paranoid, 1 borderline), 2 had substance-related disorders without other psychiatric diagnosis, and 1 had post-traumatic stress disorder (PTSD).

Out of the 32 surviving assailants for whom we have sufficient evidence, 87.5% of perpetrators of mass shootings were diagnosed with major psychiatric illness, and none were treated appropriately with medication at the time of the crime. Four assailants (12.5%) had no psychiatric diagnosis that we could discern. Of the 18 surviving assailants with schizophrenia, no assailant was on antipsychotic medication for the treatment of schizophrenia prior to the crime. Of the 10 surviving assailants with other psychiatric illnesses, no assailant was on antipsychotic and/or appropriate medication.

In addition, we found that the clinical misdiagnosis of early-onset schizophrenia was associated with the worsening of many of these assailants’ psychotic symptoms. Many of our adolescent shooters prior to the massacre had been misdiagnosed with attention-deficit disorder (ADD), major depression disorder (MDD), or autism spectrum disorder.

Though the vast majority of those suffering from psychiatric illnesses who are appropriately treated are not violent, there is a growing body of scientific research that indicates a strong association of untreated brain illness with those who commit mass shootings.^4,5,6 This research demonstrates that such untreated illness combined with access to firearms poses a lethal threat to society.

Stanford University

Most of the assailants also experienced profound estrangement, not only from families and friends, but most importantly from themselves. Being marginalized rendered them more vulnerable to their untreated psychiatric illness and to radicalization online, which fostered their violence. While there are complex reasons that a person is not diagnosed, there remains a vital need to decrease the stigma of mental illness to enable those with psychiatric illness to be more respected, less marginalized, and encouraged to receive effective psychiatric treatments.

Many of our adolescent shooters prior to the massacre had been misdiagnosed with attention-deficit disorder (ADD), major depression disorder (MDD), or autism spectrum disorder.

Though the vast majority of those suffering from psychiatric illnesses who are appropriately treated are not violent, there is a growing body of scientific research that indicates a strong association of untreated brain illness with those who commit mass shootings.^4,5,6 This research demonstrates that such untreated illness combined with access to firearms poses a lethal threat to society.

Most of the assailants also experienced profound estrangement, not only from families and friends, but most importantly from themselves. Being marginalized rendered them more vulnerable to their untreated psychiatric illness and to radicalization online, which fostered their violence. While there are complex reasons that a person is not diagnosed, there remains a vital need to decrease the stigma of mental illness to enable those with psychiatric illness to be more respected, less marginalized, and encouraged to receive effective psychiatric treatments.

TOPLINE:

A meta-analysis supports the use of mobile mental health apps, both as a standalone and added to conventional treatment, for adults with moderate to severe depression.

METHODOLOGY:

Mobile mental health apps have proliferated but data on their effectiveness in different patient populations is lacking.

To investigate, researchers conducted a systematic review and meta-analysis of 13 randomized clinical trials assessing treatment efficacy of mobile mental health apps in 1470 adults with moderate to severe depression.

The primary outcome was change in depression symptoms from pre- to post-treatment; secondary outcomes included patient-level factors associated with app efficacy.

TAKEAWAY: 

Mobile app interventions were associated with significantly reduced depressive symptoms vs both active and inactive control groups, with a medium effect size (standardized mean difference [SMD] 0.50).

App interventions delivered for < 8 weeks had a significantly greater effect size than those delivered for 8+ weeks (SMD 0.77 vs 0.43). Apps were more effective in patients not on medication or in therapy. Apps offering rewards or incentives also appeared to be more effective.

Interventions with in-app notifications were associated with significantly lower treatment outcomes (SMD 0.45) than interventions without (SMD 0.45 vs 0.71).

IN PRACTICE:

“The significant treatment efficacy of app-based interventions compared with active and inactive controls suggests the potential of mobile app interventions as an alternative to conventional psychotherapy, with further merits in accessibility, financial affordability, and safety from stigma,” the authors write.

The study, with first author Hayoung Bae, BA, with Korea University School of Psychology, Seoul, South Korea, was published online November 20 in JAMA Network Open .

LIMITATIONS:

The findings are based on a small number of trials, with significant heterogeneity among the included trials. The analysis included only English-language publications. Using summary data for the subgroup analyses might have prevented a detailed understanding of the moderating associations of individual participant characteristics.

DISCLOSURES:

The study was supported by a grant from the National Research Foundation funded by the Korean government. The authors report no relevant financial relationships.

TOPLINE:

Salivary microbiota changes caused by cigarette smoking may affect metabolic pathways and increase disease risk.

METHODOLOGY:

The researchers analyzed health information and data on the composition of salivary microbiota from 1601 adult participants in the Cooperative Health Research in South Tyrol (CHRIS) microbiome study (CHRISMB); CHRIS is an ongoing study in Italy.

The average age of the study population was 45 years; 53% were female, and 45% were current or former smokers.

The researchers hypothesized that changes in salivary microbial composition would be associated with smoking, with more nitrate-reducing bacteria present, and that nitrate reduction pathways would be reduced in smokers.

TAKEAWAY:

The researchers identified 44 genera that differed in the salivary microbiota of current smokers and nonsmokers. In smokers, seven genera in the phylum Proteobacteria were decreased and six in the phylum Actinobacteria were increased compared with nonsmokers; these phyla contain primarily aerobic and anaerobic taxa, respectively.

Some microbiota changes were significantly associated with daily smoking intensity; genera from the classes Betaproteobacteria (Lautropia or Neisseria), Gammaproteobacteria (Cardiobacterium), and Flavobacteriia (Capnocytophaga) decreased significantly with increased grams of tobacco smoked per day, measured in 5-g increments.

Smoking was associated with changes in the salivary microbiota; the nitrate reduction pathway was significantly lower in smokers compared with nonsmokers, and these decreases were consistent with previous studies of decreased cardiovascular events in former smokers.

However, the salivary microbiota of smokers who had quit for at least 5 years resembled that of individuals who had never smoked.

IN PRACTICE:

“Decreased microbial nitrate reduction pathway abundance in smokers may provide an additional explanation for the effect of smoking on cardiovascular and periodontal diseases risk, a hypothesis which should be tested in future studies,” the researchers wrote.

SOURCE:

The lead author of the study was Giacomo Antonello, MD, of Eurac Research, Affiliated Institute of the University of Lübeck, Bolzano, Italy. The study was published online in Scientific Reports (a Nature journal) on November 2, 2023.

LIMITATIONS:

The cross-sectional design and lack of professional assessment of tooth and gum health were limiting factors, as were potential confounding factors including medication use, diet, and alcohol intake.

DISCLOSURES:

The study was supported by the Department of Innovation, Research and University of the Autonomous Province of Bolzano-South Tyrol and by the European Regional Development Fund. The CHRISMB microbiota data generation was funded by the National Institute of Dental and Craniofacial Research. The researchers had no financial conflicts to disclose.

The 2024 updates to the Medicare Physician Fee Schedule (MPFS) and the Hospital Outpatient Prospective Payment System (OPPS) and Ambulatory Surgery Center (ASC) final rules represent a mixed bag for gastroenterologists.

Medicare Physician Fee Schedule (MPFS) Final Rule

Cuts to physician payments continue: The final calendar year (CY) 2024 MPFS conversion factor will be $32.7442, a cut of approximately 3.4% from CY 2023, unless Congress acts. The reduction is the result of several factors, including the statutory base payment update of 0 percent, the reduction in assistance provided by the Consolidated Appropriations Act, 2023 (from 2.5% for 2023 to 1.25% for 2024), and budget neutrality adjustments of –2.18 percent resulting from CMS’ finalized policies.

New add-on code for complex care: CMS is finalizing complexity add-on code, G2211 (Visit complexity inherent to evaluation and management associated with medical care services that serve as the continuing focal point for all needed health care services and/or with medical care services that are part of ongoing care related to a patient’s single, serious condition or a complex condition), that it originally proposed in 2018 rulemaking. CMS noted that G2211 cannot be used with an office and outpatient E/M procedure reported with modifier –25. CMS further clarified that the add-on code “is not intended for use by a professional whose relationship with the patient is of a discrete, routine, or time-limited nature ...” CMS further stated, “The inherent complexity that this code (G2211) captures is not in the clinical condition itself ... but rather the cognitive load of the continued responsibility of being the focal point for all needed services for this patient.” For gastroenterologists, it is reasonable to assume G2211 could be reported for care of patients with complex, chronic conditions such as inflammatory bowel disease (IBD), celiac disease, and/or chronic liver disease.

CMS to align split (or shared) visit policy with CPT rules: Originally, CMS proposed to again delay “through at least December 31, 2024” its planned implementation of defining the “substantive portion” of a split/shared visit as more than half of the total time. However, after the American Medical Association’s CPT Editorial Panel, the body responsible for maintaining the CPT code set, issued new guidelines for split (or shared) services CMS decided to finalize the following policy to align with those guidelines: “Substantive portion means more than half of the total time spent by the physician and nonphysician practitioner performing the split (or shared) visit, or a substantive part of the medical decision making except as otherwise provided in this paragraph. For critical care visits, substantive portion means more than half of the total time spent by the physician and nonphysician practitioner performing the split (or shared) visit.”

While the CPT guidance states, “If code selection is based on total time on the date of the encounter, the service is reported by the professional who spent the majority of the face-to-face or non-face-to-face time performing the service,” this direction does not appear in the finalized CMS language.

CMS has extended Telehealth flexibility provisions through Dec. 31, 2024:

• Reporting of Home Address — CMS will continue to permit distant site practitioners to use their currently enrolled practice location instead of their home address when providing telehealth services from their home through CY 2024.
• Place of Service (POS) for Medicare Telehealth Services — Beginning in CY 2024, claims billed with POS 10 (Telehealth Provided in Patient’s Home) will be paid at the non-facility rate, and claims billed with POS 02 (Telehealth Provided Other than in Patient’s Home) will be paid at the facility rate. CMS also clarified that modifier –95 should be used when the clinician is in the hospital and the patient is at home.
• Direct Supervision with Virtual Presence — CMS will continue to define direct supervision to permit the presence and “immediate availability” of the supervising practitioner through real-time audio and visual interactive telecommunications through CY 2024.
• Supervision of Residents in Teaching Settings — CMS will allow teaching physicians to have a virtual presence (to continue to include real-time audio and video observation by the teaching physician) in all teaching settings, but only in clinical instances when the service is furnished virtually, through CY 2024.
• Telephone E/M Services — CMS will continue to pay for CPT codes for telephone assessment and management services (99441-99443) through CY 2024.

Hospital Outpatient Prospective Payment System (OPPS) and Ambulatory Surgery Center (ASC) Final Rule

Hospital and ASC payments will increase: Conversion factors will increase 3.1% to $87.38 for hospitals and $53.51 for ASCs that meet applicable quality reporting requirements.

Hospital payments for Peroral Endoscopic Myotomy (POEM) increase: The GI societies successfully advocated for a 67% increase to the facility payment for POEM. To better align with the procedure’s cost, CMS will place CPT code 43497 for POEM into a higher-level Ambulatory Payment Classification (APC) (5331 — Complex GI procedures) with a facility payment of $5,435.83.

Cuts to hospital payments for some Level 3 upper GI procedures: CMS has finalized moving the following GI CPT codes that had previously been assigned to APC 5303 (Level 3 Upper GI Procedures — $3,260.69) to APC 5302 (Level 2 Upper GI Procedures — $1,814.88) without explanation and against advice from AGA and the GI societies. This will result in payment cuts of 44% to hospitals.

• 43252 (EGD, flexible transoral with optical microscopy)
• 43263 (ERCP with pressure measurement, sphincter of Oddi)
• 43275 (ERCP, remove foreign body/stent biliary/pancreatic duct)

GI Comprehensive APC complexity adjustments: Based on a cost and volume threshold, CMS sometimes makes payment adjustments for Comprehensive APCs when two procedures are performed together. In response to comments received, CMS is adding the following procedures to the list of code combinations eligible for an increased payment via the Complexity Adjustment.

• CPT 43270 (EGD, ablate tumor polyp/lesion with dilation and wire)
• CPT 43252 (EGD, flexible transoral with optical microscopy)

• Telephone E/M Services — CMS will continue to pay for CPT codes for telephone assessment and management services (99441-99443) through CY 2024.

Hospital Outpatient Prospective Payment System (OPPS) and Ambulatory Surgery Center (ASC) Final Rule

Hospital and ASC payments will increase: Conversion factors will increase 3.1% to $87.38 for hospitals and $53.51 for ASCs that meet applicable quality reporting requirements.

Hospital payments for Peroral Endoscopic Myotomy (POEM) increase: The GI societies successfully advocated for a 67% increase to the facility payment for POEM. To better align with the procedure’s cost, CMS will place CPT code 43497 for POEM into a higher-level Ambulatory Payment Classification (APC) (5331 — Complex GI procedures) with a facility payment of $5,435.83.

Cuts to hospital payments for some Level 3 upper GI procedures: CMS has finalized moving the following GI CPT codes that had previously been assigned to APC 5303 (Level 3 Upper GI Procedures — $3,260.69) to APC 5302 (Level 2 Upper GI Procedures — $1,814.88) without explanation and against advice from AGA and the GI societies. This will result in payment cuts of 44% to hospitals.

• 43252 (EGD, flexible transoral with optical microscopy)
• 43263 (ERCP with pressure measurement, sphincter of Oddi)
• 43275 (ERCP, remove foreign body/stent biliary/pancreatic duct)

GI Comprehensive APC complexity adjustments: Based on a cost and volume threshold, CMS sometimes makes payment adjustments for Comprehensive APCs when two procedures are performed together. In response to comments received, CMS is adding the following procedures to the list of code combinations eligible for an increased payment via the Complexity Adjustment.

• CPT 43270 (EGD, ablate tumor polyp/lesion with dilation and wire)
• CPT 43252 (EGD, flexible transoral with optical microscopy)

The Diagnosis: Merkel Cell Carcinoma

Multiple diagnoses should be considered for a small, round, blue cell neoplasm of the skin, including both primary and metastatic entities. In our patient, histopathology revealed sheets and nests of infiltrative neoplastic cells with dispersed chromatin, minimal cytoplasm, and multiple mitoses (quiz image 1).¹ The lesional cells were in the dermis and superficial subcutaneous tissue but did not appear to be arising from the epidermis. Lymphovascular invasion also was evident on additional sections. Metastatic disease was identified in 3 sentinel lymph nodes from the right inguinal and right iliac regions. These features were compatible with a diagnosis of Merkel cell carcinoma (MCC).

Merkel cell carcinoma is a rare malignant neuroendocrine cutaneous tumor with a worldwide incidence of 0.1 to 1.6 cases per 100,000 individuals annually.² The typical patient is older than 75 years with fair skin and a history of extensive sun exposure. Immunocompromised individuals are predisposed and more susceptible to infection with the Merkel cell polyomavirus, which promotes oncogenesis in the majority of MCCs. Our patient’s history of combined variable immunodeficiency likely explains her presentation at a younger age.

The prognosis in patients with MCC is poor, with 5-year survival rates of 51% for local disease, 35% for nodal disease, and 14% for systemic metastases. Survival also is reduced in cases with head/ neck primary tumors and polyomavirus-negative tumors, as well as in immunocompromised patients.² Treatment of resectable MCC consists of Mohs micrographic surgery or wide local excision depending on the patient’s cosmetic concerns. Radiation therapy is recommended for cases with increased risk for recurrence or positive surgical margins, as well as when additional resection is impossible. A study investigating immunotherapy with nivolumab demonstrated complete pathologic response and radiographic tumor regression in nearly half of patients when given 4 weeks prior to surgery.³

Immunohistochemistry is essential in discerning MCC from other small blue cell tumors. Most MCC cases show positive expression of neuroendocrine markers such as synaptophysin, chromogranin, and insulinomaassociated protein 1. Perinuclear dotlike staining with cytokeratin (CK) 20 (quiz image 2) commonly is seen, but up to 15% of cases may be CK20 negative. Many of these CK20-negative cases also express CK7. This tumor also may stain with paired box 5 (PAX-5), CD99, terminal deoxynucleotidyl transferase, Ber-EP4, and CD117^1,4; melanoma stains (ie, human melanoma black [HMB] 45, SRYrelated HMB-box 10 [SOX-10], S-100, melanoma antigen recognized by T-cells 1 [MART-1]) should be negative. However, PAX-5 expression may be a potential pitfall given that B-cell lymphomas also would express that marker and could mimic MCC histologically. Therefore, other universal lymphoid markers such as CD45 should be ordered to rule out this entity. Even with one or a few aberrant stains, a diagnosis of MCC still can be rendered using the histomorphology and the overall staining profile.⁴ Of prognostic significance, p63 expression is associated with more aggressive tumors, while Bcl-2 expression is favorable, as it offers an additional targeted treatment option.^5,6

Basal cell carcinoma (BCC) is linked to excessive sun exposure and is the most common skin cancer. Similar to MCC, it typically is mitotically active and hyperchromatic; however, lymphovascular invasion or metastasis almost never is observed in BCC, whereas approximately one-third of MCC cases have metastasized by the time of diagnosis. Additionally, BCC lacks the perinuclear dotlike staining seen with CK20.^2,7 Features present in BCC that are unusual for MCC include peripheral nuclear palisading, mucin, and retraction artifact on paraffin-embedded sections (Figure 1).⁷

Leukemia cutis (or cutaneous infiltrates of leukemia) commonly displays a perivascular and periadnexal pattern in the dermis and subcutis. These infiltrates of neoplastic leukocytes can congregate into sheets, sometimes with an overlying Grenz zone, or form single-file infiltrates (Figure 2).^1,4 The neoplastic cells can be monomorphic or atypical and commonly are susceptible to crush artifact.⁴ Although the immunohistochemical profile varies depending on the etiology of the underlying leukemia, broad hematologic markers such as CD43 and CD45 are helpful to discern these malignancies from MCC.⁴

Being neuroendocrine in origin, metastatic small cell carcinoma (Figure 3) strongly mimics MCC histologically and usually stains with synaptophysin, chromogranin, and insulinoma-associated protein 1. Both tumor cells typically exhibit nuclear molding and high mitotic rates. Although small cell carcinoma is more likely to stain with high-molecular-weight cytokeratins (ie, CK7), it is not uncommon for these tumors to express lowmolecular- weight cytokeratins such as CK20. Because most cases originate from the lungs, these lesions should be positive for thyroid transcription factor 1 and negative for PAX-5, whereas MCC would show the reverse for those stains.¹ Ultimately, however, clinical correlation with imaging results is the single best methodology for differentiation.

Small cell melanoma, a variant of nevoid melanoma, can strongly resemble an MCC or a lymphoma. Usually located on the scalp or arising from a congenital nevus, small cell melanomas are aggressive and confer an unfavorable prognosis. Histologically, they consist of nests to sheets of atypical cells within the epidermis and dermis. These cells typically exhibit hyperchromatic nuclei, minimal cytoplasm, and frequent mitoses (Figure 4). Furthermore, the cells do not display maturation based on depth.⁸ These tumors usually are positive for HMB45, S-100, MART-1, SOX-10, and tyrosinase, all of which are extremely unlikely to stain an MCC.¹

Persistent chemotherapy-related amenorrhea (CRA) after treatment for breast cancer was common and associated with worse long-term quality of life among premenopausal women in a large multicenter French cohort study.

The findings, which showed a particularly increased risk of persistent CRA in older women and those who received adjuvant tamoxifen, can help inform communication, personalized counseling, and supportive care, according to the investigators.

At 1 year after treatment, CRA occurred in 1242 of 1497 women (83.0%) from the prospective, longitudinal Cancers Toxicity Study (CANTO). The rates at years 2 and 4 after treatment were 72.5% and 66.1%, respectively, Rayan Kabirian, MD, of Gustave Roussy, Villejuif, France, and Sorbonne University, Paris, and colleagues reported.

In a quality-of-life analysis conducted among 729 women from the cohort, 416 (57.1%) had persistent CRA, although 11 of 21 women aged 18-34 years who had no menses at year 2 had late menses recovery between years 2 and 4. Those with persistent CRA at year 4, compared with those who had menses recovery at any time, had significantly worse insomnia (mean difference, 9.9 points), worse systemic therapy-related adverse effects (mean difference, 3.0 points), and worse sexual functioning (mean difference, -9.2 points).

Factors associated with greater risk of persistent CRA included receipt versus non-receipt of adjuvant tamoxifen (adjusted odds ratio, 1.97), and hot flashes at diagnosis (aOR, 1.83, and older age versus age 18-34 (aORs, 1.84 for those aged 35-39 years; 5.90 for those aged 40-44 years, and 21.29 for those 45 or older).

The findings were published online November 16 in JAMA Network Open.

The study cohort included 1636 women under age 50 years (mean age of 42.2 years) at the time of diagnosis of stage I to III breast cancer. Outcomes at up to 4 years after diagnosis and enrollment between 2012 and 2017 were reported. QOL was assessed using the European Organization for Research and Treatment of Cancer (EORTC) QOL questionnaires c30 and br23.

“Breast cancer is the most commonly diagnosed tumor in women, and approximately 20% of women with breast cancer are younger than 50 years at diagnosis,” the investigators note, explaining that younger survivors have higher risk of cancer-related symptoms and quality-of-life deterioration. “In particular, treatment-related symptoms linked to the menopausal transition (ie, vasomotor symptoms and sexual problems) represent an important source of distress during and after treatment, highlighting a need to monitor and address survivorship-related problems that are specific to this population.”

The current analysis “helps answer several clinical questions about long-term trajectories of CRA and menses recovery rates by age and about factors associated with higher likelihood of CRA,” they added, noting that the findings have several clinical implications.

For example, premenopausal women should be made aware of the risks associated with chemotherapy-related premature ovarian failure and persistent CRA, and should and receive systematic oncofertility counseling, they argue.

“In addition, in light of data showing possible late [menses] recoveries, contraceptive options should also be clearly discussed,” and “[d]edicated gynecological counseling may help patients who have an inaccurate perception of infertility due to previous exposure to chemotherapy and long-term absence of menses.”

Given that a late menses recovery pattern was also observed in older age groups in the cohort, the investigators noted that choosing the optimal adjuvant endocrine treatment can pose a challenge.

“The absence of menses after completion of chemotherapy should not be used as a proxy for permanent transition to menopause, because it does not represent a reliable surrogate of gonadotoxicity,” they warned. “Adjuvant endocrine treatment choices should be based on a more thorough and comprehensive evaluation, combining absence of menses, assessments of circulating hormone levels, and gynecological ultrasonographic imaging.”

These findings “can inform personalized care pathways targeting patients at higher risk of QOL deterioration associated with a permanent menopausal transition,” they noted, concluding that “[r]isk and duration of CRA, including potential late resumption of menses and its downstream implications for QOL, should be approached using a coordinated biopsychosocial model addressing multiple dimensions of physical, psychological, and social health.

“Proactive management of premenopausal women with early breast cancer undergoing chemotherapy should also include adapted strategies for risk communication, as well as personalized counseling and early supportive care referrals.”

“Breast cancer is the most commonly diagnosed tumor in women, and approximately 20% of women with breast cancer are younger than 50 years at diagnosis,” the investigators note, explaining that younger survivors have higher risk of cancer-related symptoms and quality-of-life deterioration. “In particular, treatment-related symptoms linked to the menopausal transition (ie, vasomotor symptoms and sexual problems) represent an important source of distress during and after treatment, highlighting a need to monitor and address survivorship-related problems that are specific to this population.”

The current analysis “helps answer several clinical questions about long-term trajectories of CRA and menses recovery rates by age and about factors associated with higher likelihood of CRA,” they added, noting that the findings have several clinical implications.

For example, premenopausal women should be made aware of the risks associated with chemotherapy-related premature ovarian failure and persistent CRA, and should and receive systematic oncofertility counseling, they argue.

“In addition, in light of data showing possible late [menses] recoveries, contraceptive options should also be clearly discussed,” and “[d]edicated gynecological counseling may help patients who have an inaccurate perception of infertility due to previous exposure to chemotherapy and long-term absence of menses.”

Given that a late menses recovery pattern was also observed in older age groups in the cohort, the investigators noted that choosing the optimal adjuvant endocrine treatment can pose a challenge.

“The absence of menses after completion of chemotherapy should not be used as a proxy for permanent transition to menopause, because it does not represent a reliable surrogate of gonadotoxicity,” they warned. “Adjuvant endocrine treatment choices should be based on a more thorough and comprehensive evaluation, combining absence of menses, assessments of circulating hormone levels, and gynecological ultrasonographic imaging.”

These findings “can inform personalized care pathways targeting patients at higher risk of QOL deterioration associated with a permanent menopausal transition,” they noted, concluding that “[r]isk and duration of CRA, including potential late resumption of menses and its downstream implications for QOL, should be approached using a coordinated biopsychosocial model addressing multiple dimensions of physical, psychological, and social health.

“Proactive management of premenopausal women with early breast cancer undergoing chemotherapy should also include adapted strategies for risk communication, as well as personalized counseling and early supportive care referrals.”
