Using Quantitative EEG Spectrograms to Detect Seizure Subtypes
Seizure; 2018 Feb; Goenka et al.

Using quantitative EEG (QEEG) can help differentiate among several types of seizures suggests an analysis of 562 seizures among 58 patitents.

  • Investigators from Montefiore Medical Center and Albert Einstein College of Medicine in New York evaluated the sensitivity of the Persyst 12 QEEG spectrograms for detecting focal, focal with secondary generalized, and generalized onset seizures.
  • Patients included in the analysis had 2 or more seizures successfully recorded during continuous EEG monitoring in the ICU or epilepsy monitoring unit from July 2016 to January 2017.
  • QEEG spectrograms detected seizures with a sensitivity of 43% to 72%.
  • Asymmetry spectrograms generated the highest sensitivity for detecting local seizures (94%).
  • FFT spectrograms were most sensitive for diagnosing secondarily generalized seizures (84%).
  • Seizure detection trend was most sensitive for generalized onset seizures (79%).

Cognitive Impairment Linked to Depression in Epilepsy
Epilepsy Behav; 2018 April; Feldman et al.

Cognitive impairment affects 40% of adult patients with epilepsy and is associated with mental depression, seizure frequency, and the number of adverse effects of antiepileptic drugs, according to an analysis of a Cleveland Clinic database.

  • Adults with epilepsy enrolled in the Cleveland Clinic Knowledge Program Data Registry from January to May 2015 were included in the analysis.
  • The patients had completed several assessment scales, including the Aldenkamp–Baker Neuropsychological Assessment Schedule (ABNAS), the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder scale (GAD-7), and the Quality of Life in Epilepsy questionnaire.
  • Since topiramate poses a high risk of cognitive impairment, it was used as the basis for the evaluation.
  • 270 of 670 patients (40%) reported cognitive impairment, with PHQ-9 scores, the number of adverse drug effects and the frequency of seizures most closely associated with such impairment., suggesting that these three variables could be used as predictors.

Time to rethink MCL treatment, trial design

Article Type
Changed
Fri, 12/16/2022 - 12:37

Classic mantle cell lymphoma (cMCL) has long been treated as a uniformly aggressive disease in need of similarly aggressive treatment, but that approach may be leading to overtreatment, according to one expert.

“The cMCL encompasses a broad category of lymphomas with highly variable clinical behaviors. A contemporary categorization of cMCL as a predominantly aggressive entity is misleading, as only an estimated 20% to 25% of patients with cMCL present with a symptomatic or aggressively behaving disease,” Leonid L. Yavorkovsky, MD, PhD, of the Kaiser Permanente San Jose Medical Center (Calif.), wrote in a commentary in JAMA Oncology.

While groups like the National Comprehensive Cancer Network and the European Society for Medical Oncology recommend that only older patients and those with significant comorbidities should be exempted from intensive therapy, Dr. Yavorkovsky said cMCL should be evaluated on an individual basis, looking closely at the prognostic markers Ki-67, SOX-11, and TP53 to identify asymptomatic patients who might be able to safely delay aggressive treatment. He also called for more risk-adapted patient assignment to cMCL clinical trials.

“The failure to recognize the erratic nature of cMCL in clinical studies may confound the outcome gains and, ultimately, undermine the ensuing treatment recommendations,” Dr. Yavorkovsky wrote.

CPT and relative value changes that may affect reimbursement to your ObGyn practice

Another year brings changes to Current Procedural Terminology (CPT) codes (which are developed and copyrighted by the American Medical Association) in the form of additions and revisions, and payments related to resource-based relative value scale (RBRVS) revisions for selected services. As of January 1, 2018, 2 new Category I codes pertain to laparoscopic treatments for gynecologic cancer, and the 4 existing codes for colporrhaphy have been revised to include cystourethroscopy. New Category III codes include 4 for fetal magnetocardiography and 1 for transvaginal tactile imaging. Medicare also has reevaluated certain relative value units (RVUs) in outpatient and facility settings.

New and revised Category I codes

Laparoscopic treatments for gynecologic cancer. Technologic advances in performing laparoscopic procedures have allowed for more extensive laparoscopic surgery for various gynecologic cancers and, to this end, 2 new codes have been added.

First, a new code was added to capture comprehensive laparoscopic surgical staging for gynecologic cancer. This new code, 38573, Laparoscopy, surgical; with bilateral total pelvic lymphadenectomy and peri-aortic lymph node sampling, peritoneal washings, peritoneal biopsy(ies), omentectomy, and diaphragmatic washings, including diaphragmatic and other serosal biopsy(ies), when performed, may not be reported with any other code that includes lymphadenectomy, omentectomy, or hysterectomy. It is intended primarily for a stand-alone staging procedure after an initial biopsy shows a gynecologic malignancy such as ovarian cancer. This new code has been valued at 33.59 RVUs.

Second, a new code was added to capture laparoscopic debulking in conjunction with hysterectomy. The new code, 58575, Laparoscopy, surgical, total hysterectomy for resection of malignancy (tumor debulking), with omentectomy including salpingo-oophorectomy, unilateral or bilateral, when performed, has been valued at 53.62 RVUs. The open equivalent to this new code is 58953, Bilateral salpingo-oophorectomy with omentectomy, total abdominal hysterectomy and radical dissection for debulking.

Cystourethroscopy. The revisions involve no longer permitting separate reporting of 52000, Cystourethroscopy (separate procedure), with the colporrhaphy codes 57240−57265. The rationale behind this change was that surgeons were routinely performing cystoscopy at the time of these procedures and therefore it should become part of the surgical procedure. Currently the Medicare National Correct Coding Initiative (NCCI) bundles 52000 with these 4 codes, but only code 57250 allows for the use of a modifier -59 to bypass the edit if the purpose of the cystoscopy was evaluation of a distinct complaint or problem (such as evaluating patient-expressed urinary symptoms prior to the surgery that were investigated at the time of the prolapse surgery). When codes 57240, 57260, or 57265 are billed along with 52000, the cystoscopy will be denied and a modifier -59 cannot be reported to bypass this edit.

New Category III codes

The new Category III codes represent emerging technology, and it is important to report them, rather than an unlisted code, if the procedures described are performed so that data can be collected for later consideration to make these Category I CPT codes. Since these codes are not assigned relative values, the provider will need to let the payer know which existing CPT Category I code most closely represents the work involved.

Fetal magnetocardiography. The new Category III codes for fetal magnetocardiography describe essentially a fetal electrocardiogram (ECG) that would be performed to assess fetal arrhythmias by placing up to 3 leads on the mother’s abdomen. Possible comparison codes for physician work might include 59050, fetal monitoring by consultant during labor; 93000−93010, 12-lead ECG, or 93040−93042, rhythm strip up to 3 leads. However, because the equipment is very expensive, these codes would not capture practice expense and the physician would have to negotiate a reasonable reimbursement level with the payer, if the magnetocardiography was a covered service. The new codes are as follows:

  • 0475T, Recording of fetal magnetic cardiac signal using at least 3 channels; patient recording and storage, data scanning with signal extraction, technical analysis and result, as well as supervision, review, and interpretation of report by a physician or other qualified health care professional
  • 0476T, Recording of fetal magnetic cardiac signal using at least 3 channels; patient recording, data scanning, with raw electronic signal transfer of data and storage
  • 0477T, Recording of fetal magnetic cardiac signal using at least 3 channels; signal extraction, technical analysis, and result.

Transvaginal tactile imaging. The new Category III code, 0487T, Biomechanical mapping, transvaginal, with report, describes the use of a pressure sensor probe inserted into the vaginal canal to measure and collect data on pelvic muscle strength, elasticity, tissue integrity, and tone. These data produce images in real time that are mapped to produce a report for physician review, interpretation, and report. The data allow quantification of pelvic floor dysfunction and may be useful in determining the most appropriate treatment (whether surgical or medical) for this gynecologic condition. The procedure uses a transvaginal probe like an ultrasound, so using 76830, transvaginal ultrasound, would not be unreasonable as a comparison code as a start.

Medicare relative value changes

Every year, Medicare reevaluates potentially misvalued CPT codes and this year was no exception. The TABLE represents the winners and losers for codes in the outpatient and facility settings that have increased or decreased RVUs by more than 10%.

Alcohol dependence may accelerate aging, frontal cortical deficits

Study’s evidence ‘compelling’
Article Type
Changed
Fri, 01/18/2019 - 17:28

Alcoholism compounds age-associated volume deficits in the frontal cortex, independent of the additional effects of drug dependence or hepatitis C infection, suggests new research published March 14 in JAMA Psychiatry.

Edith V. Sullivan, PhD, and her coauthors reported the results of a 14-year longitudinal study that used magnetic resonance imaging to examine the brains of 116 participants with alcohol dependence and 96 age-matched controls.

They found that participants with alcohol dependence as defined by the DSM-IV had significantly greater gray matter volume deficits in their frontal, temporal, parietal, cingulate and insular cortices, compared with controls – most prominently in the frontal subregions – with the only exception being the occipital lobe. When age was taken into account, age-related volume deficits were seen in the control group in five of the six cortical regions, but the alcoholism group showed a significantly greater deficit in the precentral and superior frontal cortex.

Epifantsev/Thinkstock
There was also a correlation trend between total lifetime alcohol consumption and smaller age-adjusted frontal cortical volumes, while participants with later-onset alcoholism also had smaller age-adjusted frontal cortical volumes compared with earlier-onset.

Dr. Sullivan, of the department of psychiatry and behavioral sciences at Stanford (Calif.) University, and her coauthors said the presence of age-alcoholism interactions puts older alcohol-dependent individuals at greater risk of age-associated functional compromise, even if their excessive drinking starts later in life.

More than half of individuals in the alcoholism group (54.5%) also reported drug dependence. The imaging showed that participants with alcohol use disorder who also reported opiate or cocaine use had smaller frontal cortex volumes compared with those who were not drug users. However, the non–drug-dependent participants in the group still showed deficits in precentral, supplementary motor and medial cortices volumes, compared with controls.

“These findings in alcohol-dependent and control participants, examined 1 to 8 times or more during intervals of 1 week to 12.5 years, representing, to our knowledge, the largest and longest-studied group to date, support our study hypotheses regarding alcoholism-associated accelerated aging and cortical volume deficits independent of drug dependence or HCV infection comorbidity,” the authors wrote.

“We observed a selectivity of frontal cortex to age-alcoholism interaction beyond normal aging effects and independent of deficits related to drug dependence.”

The study also showed a correlation between hepatitis C infection, alcoholism, and smaller frontal cortex volumes in those with both, compared with those with alcoholism alone and compared with controls. “Thus, HCV infection, while having focal effects on frontal brain systems, targeted frontally based systems also vulnerable to chronic and extensive alcohol consumption,” the authors wrote. “Whether the compounded untoward effects of alcoholism and HCV infection on brain structure can be ameliorated with successful treatment of the infection remains to be determined.”

Dr. Sullivan and her coauthors cited several limitations. For example, non–alcohol-dependent or HCV-infected comparison groups were not available for analysis.

The study was supported by the National Institute on Alcohol Abuse and Alcoholism, and the Moldow Women’s Hope and Heal Fund. No conflicts of interest were declared.

With an aging population that is also showing significant increases in alcohol use and misuse, studies of the interaction between alcohol and aging and the brain are highly significant. The most compelling finding of this study is the impact of that interaction on the frontal cortex volume, because of the key role this region of the brain plays in executive function.

Deficits in frontal cortical volume associated with aging are hypothesized to also result in impulsivity and compulsivity, which opens up the possibility of greater vulnerability to alcohol use disorder later in life. So as excessive alcohol consumption contributes to this aging process, this aging process also might contribute to excessive drinking in the elderly as a form of self-medication of the negative emotional states associated with aging.

“The study ... provides compelling evidence that alcohol misuse during later adulthood could confer a greater risk of deficits in frontal lobe function beyond the deficits that typically occur with aging,” wrote George F. Koob, PhD.

Given this, it is critical that strategies be explored and implemented aimed at addressing the misuse of alcohol by older drinkers. “As Yoda might say, ‘Protect their brains, we must.’ ”

Study’s evidence ‘compelling’

Alcoholism compounds age-associated volume deficits in the frontal cortex, independent of the additional effects of drug dependence or hepatitis C infection, suggests new research published March 14 in JAMA Psychiatry.

Edith V. Sullivan, PhD, and her coauthors reported the results of a 14-year longitudinal study that used magnetic resonance imaging to examine the brains of 116 participants with alcohol dependence and 96 age-matched controls.

They found that participants with alcohol dependence as defined by the DSM-IV had significantly greater gray matter volume deficits in their frontal, temporal, parietal, cingulate and insular cortices, compared with controls – most prominently in the frontal subregions – with the only exception being the occipital lobe. When age was taken into account, age-related volume deficits were seen in the control group in five of the six cortical regions, but the alcoholism group showed a significantly greater deficit in the precentral and superior frontal cortex.

There was also a correlation trend between total lifetime alcohol consumption and smaller age-adjusted frontal cortical volumes, while participants with later-onset alcoholism also had smaller age-adjusted frontal cortical volumes compared with earlier-onset.

Dr. Sullivan, of the department of psychiatry and behavioral sciences at Stanford (Calif.) University, and her coauthors said the presence of age-alcoholism interactions puts older alcohol-dependent individuals at greater risk of age-associated functional compromise, even if their excessive drinking starts later in life.

More than half of individuals in the alcoholism group (54.5%) also reported drug dependence. The imaging showed that participants with alcohol use disorder who also reported opiate or cocaine use had smaller frontal cortex volumes compared with those who were not drug users. However, the non–drug-dependent participants in the group still showed deficits in precentral, supplementary motor and medial cortices volumes, compared with controls.

FDA approves continuous glucose monitor with AI assistant

The Food and Drug Administration approved Medtronic’s Guardian Connect continuous glucose monitoring (CGM) system for use in people with diabetes between the ages of 14 and 75 years old.

The first CGM to use artificial intelligence for this purpose, the Guardian Connect system is intended to help people with diabetes who use multiple daily injections of insulin to manage their diabetes by helping them prevent hyperglycemia and hypoglycemia, according to a statement from Medtronic.

Guardian Connect utilizes a predictive algorithm that alerts patients of significant swings in blood glucose levels up to 60 minutes prior to the event. When combined with the Guardian Sensor 3, which is placed on the abdomen to monitor blood glucose levels, the Guardian Connect system was accurate and was able to alert patients about 98.5% of hypoglycemic events, according to the results of a clinical trial. This information can also be shared and monitored with care takers and family member in real time or via text message.

Perhaps the most intriguing aspect of using the Guardian Connect system is exclusive access to the Sugar.IQ smart diabetes assistant. Utilizing artificial intelligence technology from IBM Watson Health, the Sugar.IQ assistant continually analyzes how patient’s blood glucose levels respond to factors like food intake, insulin dosages, and daily routines. The combination of continuous monitoring and real-time analysis may be able to identify patterns and lead to personalized insights that will help patients with diabetes keep their blood glucose levels under control.

 

 

“Despite proven benefits and advances in technology, only a minority of insulin-using people with diabetes currently use continuous glucose monitors,” Timothy Bailey, MD, the director of the AMCR Institute and a clinical associate professor at University of California, San Diego, said in a statement. “Newer sensors paired with intelligent algorithms that help to both predict and understand glucose excursions, particularly hypoglycemia, will make diabetes safer and more comprehensible for people who inject insulin. Greater utilization of smarter CGM systems promises to allow our patients to achieve more glycemic time-in-range and to further reduce the risk of hypoglycemia,” he said.

Similar products have been approved in the last 6 months, but they have not utilized artificial intelligence and continuous analysis.

No serious adverse events were reported in the clinical trial of Guardian Connect, but less serious adverse events were observed, including gastroenteritis, upper respiratory infection, worsening of benign prostatic hyperplasia, rash, and blisters.

Guardian Connect should be available commercially sometime this summer.

CAR T before transplant yields durable remission in B-cell malignancies

Article Type
Changed
Fri, 01/04/2019 - 10:20

– Chimeric antigen receptor (CAR) T-cell therapy may be an effective bridge to hematopoietic cell transplant (HCT) for high-risk B-cell malignancies, according to a systematic analysis of patient data from the National Cancer Institute.

Additionally, patients who have received CAR T-cell therapy are likely to enter HCT with a minimal residual disease (MRD)–negative complete response, which raises the possibility of a significantly less intense conditioning regimen that could omit total body irradiation (TBI), Haneen Shalabi, DO, said at the combined annual meetings of the Center for International Blood & Marrow Transplant Research and the American Society for Blood and Marrow Transplantation.

“Patients who underwent HCT post–CAR T therapy did not have increased transplant-related morbidity or mortality,” said Dr. Shalabi, a pediatric oncologist in the hematologic diseases division of the National Cancer Institute’s pediatric oncology branch.

The combined approach also overcomes the frequent relapses seen after CAR T-cell therapy in this population. Of the 45 patients who received CAR T-cell therapy and achieved MRD-negative complete response as measured by flow cytometry, 20 did not go on to receive HCT. Of the 20 who didn’t receive HCT, 16 (80%) relapsed; 19 of the 20 (95%) had received prior HCT, said Dr. Shalabi.

 

 

However, of the 25 patients who proceeded on to receive HCT, 15 (60%) were in ongoing remission, with a median duration of 35 months (range, 11-55 months). Six patients (24%) experienced transplant-related mortality; four of these patients had no prior HCT. Ten patients (40%) experienced acute graft-versus-host disease (GVHD); two of these patients experienced grade 4 GVHD, and one experienced grade 3 GVHD.

Of the 25 patients who went on to HCT, 19 were receiving their first transplant, with a median time to transplant after CAR T-cell therapy of 57 days. Five patients (20%) had primary refractory disease. Most patients (n = 18; 72%) had TBI-based conditioning prior to their post–CAR T-cell therapy HCT. The median patient age was 15 (range, 5-30) years.

The systematic review included patients from two phase 1 studies; one was of CD19-28z CAR T-cell therapy for children and young adults with B-cell leukemia or lymphoma, and the other was of CD22-41BB CAR T-cell therapy for children and young adults with recurrent or refractory B-cell malignancies expressing CD22.

To weigh the benefit of the combined CAR T-cell therapy/HCT approach, Dr. Shalabi and her colleagues used a competing risk analysis to determine the risk of relapse post-HCT versus the risk of transplant-related mortality. Among patients undergoing their first HCT, the researchers found a 12-month cumulative incidence of relapse of 5.3% with the combined CAR T-cell therapy/HCT approach (95% confidence interval, 0.3%-22.1%). The 24-month cumulative incidence of relapse was 11.3% (95% CI, 1.7%-31.1%).

 

 

The analysis also showed the value of next-generation sequencing (NGS). “As we think about utilizing CAR T therapy as a bridge to transplant, we wanted to study the depth of CAR T–induced remission by next-gen sequencing,” Dr. Shalabi said.

Eight patients on the CD22 CAR trial had MRD analyses based on both flow cytometry and NGS. According to flow cytometry, all eight were MRD negative by 1 month; however, according to NGS, two did have detectable disease, which decreased with time. “Next-gen sequencing can identify earlier time points for relapse or ongoing remission” than flow cytometry can, she said.

An additional finding was that two-thirds of the patients who received the CD19/CD28z CAR T cells had no detectable CAR T cells when the pre-HCT conditioning regimen was initiated, said Dr. Shalabi. “CAR persistence – or lack thereof – didn’t impact post-HCT outcomes,” she said, adding that shorter-acting CAR T cells may actually be preferable when HCT is readily available as an option.

“The impact of CAR persistence peritransplant requires further analysis,” Dr. Shalabi said. It’s possible, though, that “consolidative HCT following CAR may synergistically improve event-free and overall survival for this high-risk population.”
 

 

Looking forward, Dr. Shalabi and her team are asking bigger questions: “For future directions – and this is a very big question that those in the room would probably like to know – by inducing NGS-negativity, can CAR T therapy allow for HCT conditioning deintensification, potentially reducing the risk of TRM [transplant-related mortality] and long term comorbidities?”

A future trial will explore outcomes for a conditioning regimen that omits TBI for patients who are MRD-negative by NGS, said Dr. Shalabi.

Another direction for her team’s research is to see whether introducing CAR T-cell therapy earlier in a very-high-risk population may improve outcomes; the current study population was heavily pretreated, Dr. Shalabi said.

Dr. Shalabi is employed by the National Cancer Institute. She reported no conflicts of interest.

The analysis also showed the value of next-generation sequencing (NGS). “As we think about utilizing CAR T therapy as a bridge to transplant, we wanted to study the depth of CAR T–induced remission by next-gen sequencing,” Dr. Shalabi said.

Eight patients on the CD22 CAR trial had MRD analyses based on both flow cytometry and NGS. According to flow cytometry, all eight were MRD negative by 1 month; however, according to NGS, two did have detectable disease, which decreased with time. “Next-gen sequencing can identify earlier time points for relapse or ongoing remission” than flow cytometry can, she said.

An additional finding was that two-thirds of the patients who received the CD19/CD28z CAR T cells had no detectable CAR T cells when the pre-HCT conditioning regimen was initiated, said Dr. Shalabi. “CAR persistence – or lack thereof – didn’t impact post-HCT outcomes,” she said, adding that shorter-acting CAR T cells may actually be preferable when HCT is readily available as an option.

“The impact of CAR persistence peritransplant requires further analysis,” Dr. Shalabi said. It’s possible, though, that “consolidative HCT following CAR may synergistically improve event-free and overall survival for this high-risk population.”
 

 

Looking forward, Dr. Shalabi and her team are asking bigger questions: “For future directions – and this is a very big question that those in the room would probably like to know – by inducing NGS-negativity, can CAR T therapy allow for HCT conditioning deintensification, potentially reducing the risk of TRM [transplant-related mortality] and long term comorbidities?”

A future trial will explore outcomes for a conditioning regimen that omits TBI for patients who are MRD-negative by NGS, said Dr. Shalabi.

Another direction for her team’s research is to see whether introducing CAR T-cell therapy earlier in a very-high-risk population may improve outcomes; the current study population was heavily pretreated, Dr. Shalabi said.

Dr. Shalabi is employed by the National Cancer Institute. She reported no conflicts of interest.

– Emerging data from phase 3 clinical trials are better clarifying the efficacy and safety of immunotherapy in advanced urothelial cancer and helping identify patients most likely to benefit.

An updated analysis of the KEYNOTE-045 trial showed that, compared with chemotherapy, pembrolizumab (Keytruda), an antibody to programmed death-1 (PD-1), almost doubled the 2-year survival rate in patients with recurrent or advanced urothelial cancer. No cumulative toxicity was seen.

Biomarker analyses from the IMvigor 211 trial showed that, compared with chemotherapy, atezolizumab (Tecentriq), an antibody to programmed cell death ligand 1 (PD-L1), prolonged survival by more than 7 months in patients with platinum-treated locally advanced or metastatic disease whose tumors were positive for this ligand and had a high mutational burden. The difference translated to a halving of the risk of death.

Results of both trials were reported at the 2018 Genitourinary Cancers Symposium sponsored by the American Society of Clinical Oncology, ASTRO, and the Society of Urologic Oncology.

 

 


“It is clear that PD-1 and PD-L1 targeted immunotherapy now has a role in most patients with advanced urothelial cancer,” Robert J. Jones, MBChB, PhD, professor of clinical cancer research, University of Glasgow, Beatson West of Scotland Cancer Centre, commented in an invited discussion. “It is also true that cytotoxic chemotherapy maintains a role for many, and that both modalities are often ineffective and may be toxic.”

KEYNOTE-045 trial update

Initial results of KEYNOTE-045, at a median follow-up of 14.1 months, provided level I evidence for the safety and efficacy of pembrolizumab over chemotherapy as second-line therapy for recurrent, advanced urothelial cancer (N Engl J Med. 2017;376:1015-26), leading to approval for that indication. (Pembrolizumab is also approved as first-line therapy for cisplatin-ineligible patients).

Lead investigator Joaquim Bellmunt, MD, PhD, an associate professor of medicine at Harvard Medical School and director of the Bladder Cancer Center, Dana-Farber Cancer Institute, both in Boston, reported a trial update, now at a median follow-up of 27.7 months.

Results among 542 patients showed that the initial overall survival benefit of pembrolizumab over chemotherapy (vinflunine, paclitaxel, or docetaxel) (hazard ratio, 0.73; P = .0022) was sustained and in fact now somewhat greater with longer follow-up (HR, 0.70; P = .00017).

 

 


Median overall survival was 10.3 months and 7.3 months, respectively. Corresponding 1-year survival rates were 44.4% and 29.8%, and corresponding 2-year survival rates, 27.0% and 14.3%.

At 24 months, 60.6% of patients in the chemotherapy arm had received an immunotherapy agent, including some who had received pembrolizumab as part of crossover, Dr. Bellmunt noted.

Overall survival benefit was generally similar across subgroups, including patients with PD-L1–positive tumors (defined as a combined positive score of 10% or higher) (HR, 0.56; P = .00153) and patients with PD-L1–negative tumors (HR, 0.75; P = .00859).

The lack of a progression-free survival benefit of pembrolizumab over chemotherapy in the initial analysis (HR, 0.98; P = .420) persisted in the updated analysis (HR, 0.96; P = .317).
 

 


The overall response rate now was 21.1% with pembrolizumab and 11.0% with chemotherapy. In the former group, the rate of complete response had increased from 7.0% to 9.3% with the longer follow-up. Median time to response was identical, at 2.1 months, but duration of response was longer with pembrolizumab (not reached vs. 4.4 months).

“We haven’t seen any signals of cumulative toxicity with subsequent follow-up,” Dr. Bellmunt reported. Similar to findings of the initial analysis, the most common grade 3-5 treatment-related adverse events were pruritus, fatigue, and diarrhea with pembrolizumab, and neutropenia, anemia, and fatigue with chemotherapy. As expected, the pembrolizumab group had higher rates of hypothyroidism, pneumonitis, hyperthyroidism, and colitis.

“The overall survival benefit and superior safety of pembrolizumab versus chemotherapy in this second-line patient population is maintained after 2 years of follow-up. At 24 months, 27% of patients are alive, and this is similar to what we are seeing with other immune-sensitive diseases like melanoma,” he concluded. “Results in patients with PD-L1–positive or –negative tumors were consistent with the intent-to-treat population. We have seen some hints with this biomarker, but they are not very striking.”
 

 

IMvigor 211 trial biomarker analyses

The IMvigor 211 trial enrolled 931 patients with locally advanced or metastatic urothelial carcinoma who had experienced progression during or after platinum-based chemotherapy and had received at most two prior lines of therapy.

At a median follow-up of 17.3 months, the trial did not meet its primary endpoint of significantly better overall survival with atezolizumab versus chemotherapy (vinflunine, docetaxel, or paclitaxel) in patients having PD-L1–positive tumors, defined as immunohistochemical staining of 2 or 3 (HR, 0.87; 95% confidence interval, 0.63-1.21; P = .41) (Lancet. 2018;391:748-57).

Findings were similar in the entire intention-to-treat population (HR, 0.85; 95% CI, 0.73-0.99) and in the subset with tumors having PD-L1–negative tumors, defined as immunohistochemical staining of 0 or 1 (HR, 0.84; 0.71-1.00). In an unexpected finding, PD-L1 positivity was associated with better outcome in both treatment arms.

“So PD-L1 is a classic prognostic, not predictive, biomarker,” commented lead investigator Thomas Powles, MBBS, MRCP, MD, a clinical professor of genitourinary oncology with Barts Health NHS Trust, St. Bartholomew’s Hospital, London. The investigators therefore conducted a series of analyses in the intent-to-treat population to identify predictive biomarkers.

Results were essentially the same with the tumor gene expression 3 (tGE3) signature, an RNA signature that captures expression of the genes encoding interferon gamma, a chemokine ligand, and PD-L1, and that is a marker for preexisting T-cell immunity. And they were also similar with the DNA damage response (DDR) biomarker.

 

 


However, a different pattern was seen with tumor mutational burden (TMB), a FoundationOne panel. Patients with TMB-high tumors had a substantial gain in overall survival from atezolizumab versus chemotherapy (HR, 0.68; 95% CI, 0.51-0.90), whereas those with TMB-low tumors did not (HR, 1.00; 95% CI, 0.75-1.32).

“TMB appears to be a predictive but not a prognostic biomarker,” Dr. Powles said. “It’s not perfect. Complete and partial responses and long overall survival were seen in both arms. Nevertheless, it seems like a step in the right direction.”

Finally, with insight on the nature and relationships of the various biomarkers, the investigators assessed the combination of TMB with PD-L1, finding that atezolizumab had a marked overall survival benefit in patients with TMB-high and PD-L1–positive tumors (17.8 vs. 10.6 months; HR, 0.50; 95% CI, 0.29-0.86).

“I think by using combinations of biomarkers, first-generation and second-generation, we may actually be able to better select patients for treatment in the future,” Dr. Powles concluded.
 

 

New data, new insights

“We already know the KEYNOTE-045 trial is positive,” commented the invited discussant, Dr. Jones. “This longer follow-up data is important because we need to better describe the magnitude of benefit.”

The updated survival findings are exciting because they resemble those seen with ipilimumab in melanoma, with about a fifth of patients still alive several years out, he said. Longer follow-up is needed, but “the data we see today are in keeping with the possibility that we might be seeing a similar long-term tail – the so-called immuno-oncology tail – of survival for patients with urothelial cancer as well.”

Although not statistically significant, the difference in progression-free survival is clinically important, according to Dr. Jones. This benefit is driven by both higher response rate and longer duration of response with pembrolizumab.

Long-term toxicity, especially immune-related toxicity, is also a consideration. “There is a small increment in the number of some of these toxicities, but essentially it hasn’t changed. So it would appear that there is certainly not an unexpected peak of latent immunotoxicity with this treatment,” he noted.

“Our confidence in the data for second-line pembrolizumab, if it needed to be further increased, is increased. This does help our patients make an informed decision about whether or not to accept this treatment,” he summarized.

Turning to the IMvigor 211 biomarker study, Dr. Jones said, “I would argue that the choice of second-line therapy in advanced urothelial cancer is not a clinically important decision. The reason for saying that is the case for second-line chemotherapy is poor. We’ve all used it, but we’ve never had high level evidence of benefit. … But it’s important because when we consider moving into the first-line setting, where there are active alternatives, or maybe even more into the perioperative setting, it actually could be vitally important.”

Studies of immunotherapies and targeted therapies in other cancers suggest that a clinically useful predictive biomarker will identify patients who will derive at least a doubling of favorable outcome or a halving of unfavorable outcome when given the drug as compared with a control. “So it appears that the bar has been set quite high,” Dr. Jones said.

“These IMvigor 211 data are exploratory, and they would need further independent validation, in my view,” he said. Nevertheless, “this may provide us the opportunity to use combinations of biomarkers where now we are seeing a hazard ratio of 0.50 [for risk of death] combining PD-L1 with high tumor mutational burden (TMB). That hazard ratio is bringing it into the area where it may be of a magnitude big enough to use in clinical practice, if this could be validated.”

“I would say that none of these data support a role for second-line cytotoxics after failure of platinum, at least not in preference to a checkpoint inhibitor,” Dr. Jones concluded. “There is still no biomarker to inform a choice in second-line treatment. However, TMB, either alone or in combination with other markers, shows promise, which we need to validate in future randomized trials.”

Finally, with insight on the nature and relationships of the various biomarkers, the investigators assessed the combination of TMB with PD-L1, finding that atezolizumab had a marked overall survival benefit in patients with TMB-high and PD-L1–positive tumors (17.8 vs. 10.6 months; HR, 0.50; 95% CI, 0.29-0.86).

“I think by using combinations of biomarkers, first-generation and second-generation, we may actually be able to better select patients for treatment in the future,” Dr. Powles concluded.
 

 

New data, new insights

“We already know the KEYNOTE-045 trial is positive,” commented the invited discussant, Dr. Jones. “This longer follow-up data is important because we need to better describe the magnitude of benefit.”

The updated survival findings are exciting because they resemble those seen with ipilimumab in melanoma, with about a fifth of patients still alive several years out, he said. Longer follow-up is needed, but “the data we see today are in keeping with the possibility that we might be seeing a similar long-term tail – the so-called immuno-oncology tail – of survival for patients with urothelial cancer as well.”

Although not statistically significant, the difference in progression-free survival is clinically important, according to Dr. Jones. This benefit is driven by both higher response rate and longer duration of response with pembrolizumab.

Long-term toxicity, especially immune-related toxicity, is also a consideration. “There is a small increment in the number of some of these toxicities, but essentially it hasn’t changed. So it would appear that there is certainly not an unexpected peak of latent immunotoxicity with this treatment,” he noted.

“Our confidence in the data for second-line pembrolizumab, if it needed to be further increased, is increased. This does help our patients make an informed decision about whether or not to accept this treatment,” he summarized.

Turning to the IMvigor 211 biomarker study, Dr. Jones said, “I would argue that the choice of second-line therapy in advanced urothelial cancer is not a clinically important decision. The reason for saying that is the case for second-line chemotherapy is poor. We’ve all used it, but we’ve never had high level evidence of benefit. … But it’s important because when we consider moving into the first-line setting, where there are active alternatives, or maybe even more into the perioperative setting, it actually could be vitally important.”

Studies of immunotherapies and targeted therapies in other cancers suggest that a clinically useful predictive biomarker will identify patients who will derive at least a doubling of favorable outcome or a halving of unfavorable outcome when given the drug as compared with a control. “So it appears that the bar has been set quite high,” Dr. Jones said.

“These IMvigor 211 data are exploratory, and they would need further independent validation, in my view,” he said. Nevertheless, “this may provide us the opportunity to use combinations of biomarkers where now we are seeing a hazard ratio of 0.50 [for risk of death] combining PD-L1 with high tumor mutational burden (TMB). That hazard ratio is bringing it into the area where it may be of a magnitude big enough to use in clinical practice, if this could be validated.”

“I would say that none of these data support a role for second-line cytotoxics after failure of platinum, at least not in preference to a checkpoint inhibitor,” Dr. Jones concluded. “There is still no biomarker to inform a choice in second-line treatment. However, TMB, either alone or in combination with other markers, shows promise, which we need to validate in future randomized trials.”

Easing into laparoscopic colectomy

Article Type

Wed, 01/02/2019 - 10:07

Minimally invasive techniques have clear benefits for colectomy, including reduced hospital length of stay, less pain, faster return to work, and reduced incidence of adhesive small bowel obstructions. But the methods are underutilized, in part because they can be challenging to learn.

But he believes that the hand-assist technique gets a bad rap because of selection bias. More difficult cases are done with the hand-assist approach, and tend to have worse outcomes. “[Hand assist] is awfully useful for some of these tougher cases,” said Dr. Paquette. In challenging cases, surgeons can convert a laparoscopic surgery to a hand-assist procedure rather than an open procedure, though this requires some practice in keeping your free hand away from the dissection.

One high-volume surgeon showed what happened over time when his practice employed hand-assisted laparoscopy for diverticulitis cases (Dis Colon Rectum. 2014;57[9]1090-7). Initially, most cases were done with the hand-assist technique. Over time, that percentage dropped precipitously and the number that were performed laparoscopically rose sharply. Throughout the study period, the percentage of open procedures remained very low, dropping to almost zero near the conclusion. “They were able to keep their experience of open surgery quite low by using hand-assisted techniques to help with the tough cases of diverticular disease and get over that learning curve,” said Dr. Paquette.

In colon cancer, the study found that laparoscopic procedures hovered around 50%, while open and hand-assisted techniques tended to be around 20%. The higher incidence of open procedures was probably due to the desire of surgeons to be certain that the entire tumor has been excised. “If you’re in doubt, you don’t compromise on oncology. You do an open procedure if you need to,” said Dr. Paquette.

Another tool available to surgeons is single-incision laparoscopic colectomy, as opposed to conventional multiport laparoscopic colectomy. The method results in a very small incision, but can be challenging because the instruments are closer together and it is tricky when the surgeon has to cross the instrument, he said.

Dr. Paquette’s own group also looked at extraction in hand-assisted sigmoid colectomy, in which the surgeon went in laparoscopically, mobilized the colon laterally as would be done in an open procedure, and then performed the colectomy through a small extraction incision. The length of stay was about 15% shorter, there was a lower readmission rate, and gastrointestinal function returned more quickly (Surg Endosc. 2016 Aug;30[8]:3567-72).

Can patients who previously underwent a midline laparotomy be treated laparoscopically? “The answer is possibly yes,” said Dr. Paquette. He noted one study that showed higher rates of minor morbidity, ileotomy, and longer length of stay with laparoscopic treatment (Surg Endosc. 2015;29[3]537-42). “It’s a worth a try if you carefully plan where you’re going to go in through your ports, get in off the midline somewhere if you have to, and just take a look. If you have some adhesions of the omentum to the abdominal wall, it’s really no problem and you can proceed. If you have a frozen abdomen, just do the right thing and open the patient,” said Dr. Paquette.

When it comes to extraction options, Pfannenstiel incisions have the lowest rates of incisional hernias, at 1.9%, according to a survey of 2,148 cases at the Cleveland Clinic. The periumbilical midline incision had the highest frequency at 16.2% (Dis Colon Rectum. 2016 Aug;59[8]:743-50).

“If I’m doing a laparoscopic sigmoid or a laparoscopic low anterior, I do prefer to do a Pfannenstiel incision if I can. If you think that you may need to convert that patient for some reason, don’t do the Pfannenstiel first – nobody wants that big T-shaped incision,” said Dr. Paquette.

Olopatadine/mometasone combo is safe and effective

Article Type
Changed
Fri, 01/18/2019 - 17:28

 

– Twice-daily treatment with a combination of olopatadine and mometasone showed significant clinical benefit and demonstrated safety for patients with seasonal allergic rhinitis, according to the results of a phase 3 trial.

The combination, known as GSP301, is a fixed-dose nasal spray containing olopatadine, a Food and Drug Adminstration–approved antihistamine, and mometasone, an FDA-approved corticosteroid.

Dr. Frank Hampel
In a double-blind, parallel-group study, Frank Hampel, MD, of Central Texas Health Research in New Braunfels, Tex., and his colleagues randomized 1,180 patients who had seasonal allergic rhinitis and were aged 12 years or older to receive GSP301 (olopatadine 665 mcg/mometasone 25 mcg), olopatadine (665 mcg) alone, mometasone (25 mcg) alone, or placebo twice daily. They examined change from baseline in reflective total nasal symptom scores and compared the changes across treatment groups. The mean change in baseline scores was the primary endpoint.

The combination therapy demonstrated statistically significant improvement in scores, compared with those associated with placebo (P less than .001) and olopatadine alone (P = .003). It also showed benefit when compared with mometasone alone (P = .059), Dr. Hampel reported at the joint congress of the American Academy of Allergy, Asthma, and Immunology and the World Allergy Organization.
