Importance: Mitotane (Lysodren, o,p'-DDD [1-(o-chlorophenyl)-1-(p-chlorophenyl)-2,2-dichloroethane)] is currently the only United States Food and Drug Administration and European Medicines Agency-approved product for the treatment of adrenocortical carcinoma., Observations: Mitotane is challenging to administer; however, its toxicities (specifically adrenal insufficiency) are well known, and the management of adverse consequences has established approaches. While often viewed through the prism of a cytotoxic agent, it can also interfere with hormone production making it a valuable asset in managing functional ACC. A recently completed prospective trial has shed some light on its use in the adjuvant setting, but further clarity is needed. Many think mitotane has a role in the advanced or metastatic setting, although prospective data are lacking and retrospective analyses are often difficult to interpret., Conclusions and Relevance: When used carefully and thoughtfully, especially in patients with hormonal excess, mitotane is an important component of the treatment armamentarium for ACC., (Published by Oxford University Press 2024.

Importance: Because unprofessional behaviors are associated with patient complications, malpractice claims, and well-being concerns, monitoring concerns requiring investigation and individuals identified in multiple reports may provide important opportunities for health care leaders to support all team members., Objective: To examine the distribution of physicians by specialty who demonstrate unprofessional behaviors measured through safety reports submitted by coworkers., Design, Setting, and Participants: This retrospective cohort study was conducted among physicians who practiced at the 193 hospitals in the Coworker Concern Observation Reporting System (CORS), administered by the Vanderbilt Center for Patient and Professional Advocacy. Data were collected from January 2018 to December 2022., Exposure: Submitted reports concerning communication, professional responsibility, medical care, and professional integrity., Main Outcomes and Measures: Physicians' total number and categories of CORS reports. The proportion of physicians in each specialty (nonsurgeon nonproceduralists, emergency medicine physicians, nonsurgeon proceduralists, and surgeons) who received at least 1 report and who qualified for intervention were calculated; logistic regression was used to calculate the odds of any CORS report., Results: The cohort included 35 120 physicians: 18 288 (52.1%) nonsurgeon nonproceduralists, 1876 (5.3%) emergency medicine physicians, 6743 (19.2%) nonsurgeon proceduralists, and 8213 (23.4%) surgeons. There were 3179 physicians (9.1%) with at least 1 CORS report. Nonsurgeon nonproceduralists had the lowest percentage of physicians with at least 1 report (1032 [5.6%]), followed by emergency medicine (204 [10.9%]), nonsurgeon proceduralists (809 [12.0%]), and surgeons (1134 [13.8%]). Nonsurgeon nonproceduralists were less likely to be named in a CORS report than other specialties (5.6% vs 12.8% for other specialties combined; difference in percentages, -7.1 percentage points; 95% CI, -7.7 to -6.5 percentage points; P < .001). Pediatric-focused nonsurgeon nonproceduralists (2897 physicians) were significantly less likely to be associated with a CORS report than nonpediatric nonsurgeon nonproceduralists (15 391 physicians) (105 [3.6%] vs 927 [6.0%]; difference in percentages, -2.4 percentage points, 95% CI, -3.2 to -1.6 percentage points; P < .001). Pediatric-focused emergency medicine physicians, nonsurgeon proceduralists, and surgeons had no significant differences in reporting compared with nonpediatric-focused physicians., Conclusions and Relevance: In this cohort study, less than 10% of physicians ever received a coworker report with a concern about unprofessional behavior. Monitoring reports of unprofessional behaviors provides important opportunities for health care organizations to identify and intervene as needed to support team members.

Introduction: Small bowel adenocarcinomas (SBAs) are rare and frequently treated like large intestinal adenocarcinomas. However, SBAs have a very different microenvironment and could respond differently to the same therapies. Our previous data suggested that SBAs might benefit from targeting the PD-1/PD-L1 axis based on PD-L1 staining in almost 50% of SBA tissue samples tested. Thus, we designed a phase 2 study to explore safety and efficacy of avelumab in SBA., Patients and Methods: Patients with advanced or metastatic disease were enrolled; ampullary tumors were considered part of the duodenum and allowed. Prior PD-1/PD-L1 inhibition was not allowed. Avelumab (10 mg/kg) was given every 2 weeks, and imaging was performed every 8 weeks. Primary endpoint was response rate., Results: Eight patients (n = 5, small intestine; n = 3, ampullary) were enrolled, with a majority (88%) being male and a median age of 61 years. Of 7 efficacy-evaluable patients, 2 (29%) experienced partial responses; stable disease occurred in 3 additional patients (71%). Median progression-free survival was 3.35 months. Most frequent, related toxicities were anemia, fatigue, and infusion-related reaction (25% each), mostly grade ≤2; grade 3 hypokalemia and hyponatremia occurred in one patient, and another reported grade 4 diabetic ketoacidosis., Conclusions: Despite the observed benefit, accrual was slower than expected and the study was closed early due to feasibility. A general clinic observation was that patients were receiving immunotherapy off-label as the availability of these agents increased. Off-label availability and disease rarity were likely drivers of insufficient accrual., Competing Interests: Disclosure JB is an advisory board member of Insmed, Bayer, Mirati, Ipsen, QED, Oxford Biotherapeutics DSMB: Novocure, Pancreatic Cancer Action Network, Karyopharm, and his institution has received research funding from I-Mab, Dragonfly, Astellas, Atreca, AbbVie, Pfizer, Karyopharm, Boston biomedical, PsiOxus, EMD Serono, BMS.

Background: Larotrectinib is a first-in-class, highly selective, and central nervous system-active tropomyosin receptor kinase (TRK) inhibitor approved for the treatment of adult and pediatric patients with TRK fusion cancer. We report the efficacy and safety of larotrectinib in patients with TRK fusion-positive salivary gland cancers., Patients and Methods: Patients with TRK fusion-positive salivary gland cancer treated with larotrectinib were identified from two clinical trials (NCT02122913 and NCT02576431). Patients received larotrectinib 100 mg twice daily (BID) except for one patient who received 150 mg BID in the phase I trial. The primary endpoint was objective response rate (ORR) as assessed by the investigator using Response Evaluation Criteria in Solid Tumors version 1.1., Results: At the data cut-off (July 20, 2020), 24 patients with TRK fusion-positive salivary gland cancer had been treated. The most common histologies were secretory carcinoma (54%), adenocarcinoma (25%), and mucoepidermoid carcinoma (13%). All 24 patients had an ETV6-NTRK3 gene fusion. The ORR was 92% (95% confidence interval, 73-99). Best overall response was complete response in three (13%) patients, partial response in 19 (79%), and progressive disease in two (8%). The rate of progression-free survival at 24 months was 78% (median follow-up 30.9 months). Most treatment-related adverse events (AEs) were grade 1-2, and no patients discontinued treatment due to AEs., Conclusion: Larotrectinib demonstrated robust and durable efficacy in patients with TRK fusion-positive salivary gland tumors of various histologies, and a favorable safety profile. These findings support NTRK gene fusion testing in patients with advanced salivary gland cancers., Clinicaltrials.gov Numbers: NCT02122913 and NCT02576431., (© The Author(s) 2022.

Purpose: COVID-19 challenged medical practice and graduate medical education. Building on previous initiatives, we describe and reflect on the formative process and goals of the Hematology-Oncology Collaborative Videoconferencing Learning Initiative, a trainee-led multi-institutional virtual COVID-19 learning model., Methods: Clinical fellows and faculty from 13 US training institutions developed consensus needs, goals, and objectives, recruited presenters, and generated a multidisciplinary COVID-19 curriculum. Weekly Zoom conferences consisted of two trainee-led instructional segments and a trainee-moderated faculty Q&A panel. Hematology-oncology training program faculty and trainees were the targeted audience. Leadership evaluations consisted of anonymized baseline and concluding mixed methods surveys. Presenter evaluations consisted of session debriefs and two structured focus groups. Conference evaluations consisted of attendance, demographics, and pre- or postmultiple-choice questions on topic learning objectives., Results: In 6 weeks, the initiative produced five conferences: antivirals, anticoagulation, pulmonology, provider resilience, and resource scarcity ethics. The average attendance was 100 (range 57-185). Among attendees providing both pre- and postconference data, group-level knowledge appeared to increase: antiviral (n = 46) pre-/postcorrect 82.6%/97.8% and incorrect 10.9%/2.2%, anticoagulation (n = 60) pre-/postcorrect 75%/93.3% and incorrect 15%/6.7%, and pulmonary (n = 21) pre-/postcorrect 66.7%/95.2% and incorrect 33.3%/4.8%. Although pulmonary management comfort appeared to increase, comfort managing of antivirals and anticoagulation was unchanged. At the conclusion of the pilot, leadership trainees reported improved self-confidence organizing multi-institutional collaborations, median (interquartile range) 58.5 (50-64) compared with baseline 34 (26-39), but did not report improved confidence in other educational or leadership skills., Conclusion: During crisis, trainees built a multi-institutional virtual education platform for the purposes of sharing pandemic experiences and knowledge. Accomplishment of initiative goals was mixed.

Background: Radiation for patients with head and neck cancer (HNC) is associated with painful mucositis that impacts the delivery of treatment and contributes to high symptom burden., Methods: This was a prospective, randomized pilot trial. Eligible patients received primary or adjuvant chemoradiation. Patients were randomized to usual care vs usual care plus gabapentin titrated to drug tolerance during radiation. Patients completed a symptom survey at baseline and weekly during therapy., Results: Seventy-nine patients were enrolled in the study (38 control, 41 treatment). At interim analysis, gabapentin use resulted in a decrease in pain (P = .004), with the biggest decreases being in the latter weeks of therapy. By week 7, the median pain score in the treatment group was below the 0.25 quantile of the control group., Conclusion: Prophylactic use of gabapentin during chemoradiation for HNC patients resulted in a decrease in pain, neurosensory symptoms, and general systemic symptoms., (© 2020 Wiley Periodicals LLC.)

Background: Programmed death-ligand 1 (PD-L1) protein is expressed in various cancers, including small-cell lung cancer (SCLC). Atezolizumab inhibits PD-L1 signaling, thus restoring tumor-specific T-cell immunity. Here, we report results from the first-in-human phase 1 PCD4989g study (NCT01375842) of atezolizumab, in a cohort of patients with relapsed/refractory SCLC., Patients and Methods: Eligible patients with incurable or metastatic SCLC, which was advanced or recurrent since the last antitumor therapy, received atezolizumab 15 mg/kg or 1200 mg intravenously every 3 weeks for 16 cycles or until loss of clinical benefit. The primary endpoint was safety. Efficacy and biomarkers of antitumor activity were also assessed., Results: Seventeen patients were enrolled. Any-grade and grade ≥3 treatment-related adverse events (TRAEs) occurred in 11 (64.7%) and 5 (29.4%) patients, respectively. The most common any-grade TRAE was fatigue (4 patients [23.5%]). Partial response to atezolizumab was achieved in 1 patient (5.9%) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1), and 3 (17.6%) per immune-related response criteria (irRC). Durations of response were 2.8 to > 45.7 months. Median investigator-assessed progression-free survival (PFS) per RECIST v1.1 and irRC was 1.5 (95% confidence interval [CI], 1.2-2.7) and 2.9 (95% CI, 1.2-6.1) months, respectively. Median overall survival (OS) was 5.9 months (95% CI, 4.3-12.6). Patients with high (≥ median expression) T-effector gene signature and PD-L1 mRNA expression appeared to show a trend toward improved PFS (per irRC) and OS., Conclusion: Atezolizumab was generally well tolerated and exhibited antitumor activity in a small cohort of patients with relapsed/refractory SCLC., (Copyright © 2020 The Authors.

Purpose: We evaluated the addition of bevacizumab, a humanized monoclonal antibody that targets vascular endothelial growth factor, to platinum-based chemotherapy in recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN)., Patients and Methods: Patients with chemotherapy-naïve (or with prior platinum as part of multimodal therapy completed ≥ 4 months earlier) recurrent or metastatic SCCHN were randomly assigned to receive a platinum-based chemotherapy doublet with or without bevacizumab 15 mg/kg given intravenously every 3 weeks until disease progression. Chemotherapy could be discontinued after six cycles if a maximum response was achieved., Results: The study randomly assigned 403 patients. Median overall survival (OS) was 12.6 months with bevacizumab plus chemotherapy (BC) and 11.0 months with chemotherapy alone (hazard ratio, 0.87; 95% CI, 0.70 to 1.09; P = .22). At 2, 3, and 4 years, the OS rates were 25.2% v 18.1%, 16.4% v 10.0%, and 11.8% v 6.4% for BC versus chemotherapy, respectively. In an analysis of 365 eligible patients who started treatment, the hazard ratio was 0.82 (95% CI, 0.65 to 1.04; P = .10), with a median OS of 14.2 months on BC v 11.1 months on chemotherapy. Median progression-free survival with BC was 6.0 months v 4.3 months with chemotherapy ( P = .0014). Overall response rates were 35.5% with BC and 24.5% with chemotherapy ( P = .016). There was increased toxicity, including a higher rate of treatment-related grade 3 to 5 bleeding events (6.7% v 0.5%; P < .001) and treatment-related deaths (9.3% v 3.5%; P = .022) with BC versus chemotherapy., Conclusion: The addition of bevacizumab to chemotherapy did not improve OS but improved the response rate and progression-free survival with increased toxicities. These results encourage biomarker-driven studies of angiogenesis inhibitors with better toxicity profiles in select patients with SCCHN.

Proliferating tricholemmal tumors (PTTs) are rare benign neoplasms that arise from the outer sheath of a hair follicle. Occasionally, these PTTs undergo malignant transformation to become malignant proliferating tricholemmal tumors (MPTTs). Little is known about the molecular alterations, malignant progression, and management of MPTTs. Here, we describe the case of a 58-year-old female that had a widely metastatic MPTT that harbored an activating PIK3CA mutation and was sensitive to the PI3K inhibitor, alpelisib (BYL719). We review the available literature on metastatic MPTT, detail the patient's course, and present a whole genome analysis of this rare tumor., Competing Interests: KBD has received consulting fees from Kadmon and was an invited speaker for Illumina.

Importance: Dual blockade of programmed death ligand 1 (PD-L1) and cytotoxic T-lymphocyte associated protein 4 (CTLA-4) may overcome immune checkpoint inhibition. It is unknown whether dual blockade can potentiate antitumor activity without compromising safety in patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) and low or no PD-L1 tumor cell expression., Objective: To assess safety and objective response rate of durvalumab combined with tremelimumab., Design, Setting, and Participants: The CONDOR study was a phase 2, randomized, open-label study of Durvalumab, Tremelimumab, and Durvalumab in Combination With Tremelimumab in Patients With R/M HNSCC. Eligibility criteria included PD-L1-low/negative disease that had progressed after 1 platinum-containing regimen in the R/M setting. Patients were randomized (N = 267) from April 15, 2015, to March 16, 2016, at 127 sites in North America, Europe, and Asia Pacific., Interventions: Durvalumab (20 mg/kg every 4 weeks) + tremelimumab (1 mg/kg every 4 weeks) for 4 cycles, followed by durvalumab (10 mg/kg every 2 weeks), or durvalumab (10 mg/kg every 2 weeks) monotherapy, or tremelimumab (10 mg/kg every 4 weeks for 7 doses then every 12 weeks for 2 doses) monotherapy., Main Outcomes and Measures: Safety and tolerability and efficacy measured by objective response rate., Results: Among the 267 patients (220 men [82.4%]), median age (range) of patients was 61.0 (23-82) years. Grade 3/4 treatment-related adverse events occurred in 21 patients (15.8%) treated with durvalumab + tremelimumab, 8 (12.3%) treated with durvalumab, and 11 (16.9%) treated with tremelimumab. Grade 3/4 immune-mediated adverse events occurred in 8 patients (6.0%) in the combination arm only. Objective response rate (95% CI) was 7.8% (3.78%-13.79%) in the combination arm (n = 129), 9.2% (3.46%-19.02%) for durvalumab monotherapy (n = 65), and 1.6% (0.04%-8.53%) for tremelimumab monotherapy (n = 63); median overall survival (95% CI) for all patients treated was 7.6 (4.9-10.6), 6.0 (4.0-11.3), and 5.5 (3.9-7.0) months, respectively., Conclusions and Relevance: In patients with R/M HNSCC and low or no PD-L1 tumor cell expression, all 3 regimens exhibited a manageable toxicity profile. Durvalumab and durvalumab + tremelimumab resulted in clinical benefit, with minimal observed difference between the two. A phase 3 study is under way., Trial Registration: clinicaltrials.gov Identifier: NCT02319044.

Objectives: Treatment options for patients with unresectable or metastatic salivary gland carcinoma (SGC) are limited. Safety and efficacy of pembrolizumab for SGC expressing programmed death ligand 1 (PD-L1) were explored., Materials and Methods: A cohort of patients with advanced, PD-L1-positive SGC was enrolled in the nonrandomized, multicohort, phase Ib trial of pembrolizumab in patients with PD-L1-positive advanced solid tumors (KEYNOTE-028; NCT02054806). Key inclusion criteria included recurrent or metastatic disease, failure of prior systemic therapy, and PD-L1 expression on ≥1% of tumor or stroma cells (per a prototype immunohistochemistry assay). Patients received pembrolizumab 10 mg/kg every 2 weeks for ≥2 years or until confirmed disease progression or unacceptable toxicity. Primary end point was objective response rate per Response Evaluation Criteria in Solid Tumors version 1.1 by investigator review., Results: Twenty-six patients with PD-L1-positive SGC were enrolled and treated; median age was 57 years, 88% were men, and 74% had received prior therapy for recurrent/metastatic disease. Confirmed objective response rate after median follow-up of 20 months was 12% (95% confidence interval, 2%-30%), with 3 patients achieving partial response; there were no complete responses. Median duration of response was 4 months (range, 4 to 21 mo). Treatment-related adverse events occurred in 22 patients (85%), resulting in discontinuation in 2 patients and death in 1 (interstitial lung disease); those occurring in ≥15% of patients were diarrhea, decreased appetite, pruritus, and fatigue., Conclusions: Pembrolizumab demonstrated promising antitumor activity and a manageable safety profile in patients with advanced, PD-L1-positive SGC.

Objective: This study was designed to assess the feasibility of using the Jaw Dynasplint System as an adjunct to conventional stretching exercises as a preventative measure against trismus in patients undergoing radiotherapy., Methods: Study participants (n = 40) were randomized using a permuted block design to conventional stretching or stretching plus use of the Jaw Dynasplint 3 times per day for 30 minutes. Patients were instructed to record maximum interincisal opening each day as well as logging use of the Jaw Dynasplint., Results: At 6 months after initiation of the preventative regimen, 50% of patients in the Dynasplint arm and 75% in the conventional stretching arm remained on their assigned therapy. Trismus was diagnosed in 2 patients in the control arm and in 4 patients in the Dynasplint arm. Only 25% (95% confidence interval = 11.1, 46.9) of patients in the Dynasplint arm used the device as prescribed., Conclusions: The addition of the Jaw Dynasplint decreased compliance compared with conventional stretching. It is unlikely that the prescribed regimen will prove efficacious as a preventative measure due to low compliance.

Adrenocortical carcinoma (ACC) is rare within the adult population. Ectopic ACC proves even rarer. This variant is formed by cortical fragments arrested during embryologic migration. ACC is also known to be associated with several genetic syndromes and has recently been linked to Lynch syndrome in 3% of cases. We present the case of a 68-year-old male with a confirmed diagnosis of Lynch syndrome secondary to a germline MSH2 mismatch-repair gene-mutation who presented with 2 months history of non-specific abdominal pain. After imaging work-up, the patient was found to have a right upper quadrant, retroperitoneal mass. Biochemical tests were without any evidence of a hormonally active process. Fine needle aspiration of the mass revealed a poorly differentiated carcinoma of unknown etiology. The lesion was resected and found to be consistent with ectopic ACC with an associated MSH2 mutation.

Progress in the treatment of advanced medullary thyroid cancer (MTC) has resulted from the approval of 2 drugs within the past 5 years, vandetanib and cabozantinib. These multikinase inhibitors (MKIs) possess overlapping specificities for multiple kinase targets implicated in the progression of MTC. Both drugs are associated with toxicities, including hypertension, hemorrhage/perforation, diarrhea and other gastrointestinal events, several dermatologic events, and hypothyroidism. In addition, vandetanib is uniquely associated with QTc prolongation through interaction with myocardial potassium channels, and cabozantinib is uniquely associated with hand-foot skin reaction. Treatment-related toxicities occur frequently and can be severe or life-threatening, and patients undergoing long-term treatment will likely experience adverse events (AEs). Here we offer specific practical recommendations for managing AEs commonly occurring with vandetanib and cabozantinib. The recommended approach relies on early recognition and palliation of symptoms, dose interruption, and dose reduction as necessary in order for the patient to maintain the highest tolerable dose for as long as possible and optimal quality of life. Treatment guidelines do not specify a recommended sequence for treating with vandetanib and cabozantinib; however, most patients will receive both drugs during their lifetime. The choice for first-line therapy is individualized after a risk-benefit assessment and depends on physician preference and patient-related factors, such as comorbid conditions. Because most generalist practices may not be familiar with the intricacies of agents such as vandetanib and cabozantinib, we commend that patients with advanced MTC be managed and treated by a thyroid cancer specialist with coordination of care within a multidisciplinary team., (Copyright © 2018.

PET/CT imaging is frequently used for cancer diagnosis and restaging as metabolically active cells, including cancer, utilize glucose for proliferation. F-FDG is the most commonly utilized radiopharmaceutical in PET/CT imaging. Limitations of F-FDG imaging include intense physiologic uptake in benign tissues such as the brain and myocardium. We present a case of non-small cell lung cancer with myocardial and pericardial metastases obscured by physiologic F-FDG cardiac uptake but detected with the investigational PET radiotracer (4S)-4-(3-F-fluoropropyl)-L-glutamate (F-FSPG), which targets a pathway associated with glutathione biosynthesis. This case demonstrates the added value of F-FSPG PET/CT imaging.

Recurrent and/or metastatic head and neck cancer portends a poor prognosis with traditional treatments, but current immunotherapy with immune checkpoint inhibitors has the potential to improve these clinical outcomes. This review focuses on the major breakthroughs that have led to the current understanding of immunotherapy in head and neck cancer as well as the future direction of the field. Ultimately, this understanding will guide clinicians on the selection of patients with head and neck cancer and practical considerations before starting immunotherapy., (Copyright © 2017 Elsevier Inc.

Purpose There are no approved treatments for recurrent/metastatic head and neck squamous cell carcinoma refractory to platinum and cetuximab. In the single-arm, phase II KEYNOTE-055 study, we evaluated pembrolizumab, an anti-programmed death 1 receptor antibody, in this platinum- and cetuximab-pretreated population with poor prognosis. Methods Eligibility stipulated disease progression within 6 months of platinum and cetuximab treatment. Patients received pembrolizumab 200 mg every 3 weeks. Imaging was performed every 6 to 9 weeks. Primary end points: overall response rate (Response Evaluation Criteria in Solid Tumors v1.1, central review) and safety. Efficacy was assessed in all dosed patients and in subgroups on the basis of programmed death ligand 1 (PD-L1) expression and human papillomavirus (HPV) status. Results Among 171 patients treated, 75% received two or more prior lines of therapy for metastatic disease, 82% were PD-L1 positive, and 22% were HPV positive. At the time of analysis, 109 patients (64%) experienced a treatment-related adverse event; 26 patients (15%) experienced a grade ≥ 3 event. Seven patients (4%) discontinued treatment, and one died of treatment-related adverse events. Overall response rate was 16% (95% CI, 11% to 23%), with a median duration of response of 8 months (range, 2+ to 12+ months); 75% of responses were ongoing at the time of analysis. Response rates were similar in all HPV and PD-L1 subgroups. Median progression-free survival was 2.1 months, and median overall survival was 8 months. Conclusion Pembrolizumab exhibited clinically meaningful antitumor activity and an acceptable safety profile in recurrent/metastatic head and neck squamous cell carcinoma previously treated with platinum and cetuximab.

Advanced biliary tract cancers (ABTC) are among the deadliest malignancies with limited treatment options after progression on standard-of-care chemotherapy, which includes gemcitabine (GEM) and oxaliplatin (OX). The epidermal growth factor receptor inhibitor erlotinib has been explored in ABTC with modest efficacy. Erlotinib given continuously may antagonize the action of chemotherapy against cycling tumor cells, but pulsatile dosing of erlotinib with chemotherapy may improve efficacy. The purpose of this study was to assess the safety of pulsatile erlotinib with GEMOX. This was a single-institution phase Ib study that enrolled adult patients with unresectable or metastatic biliary tract, pancreas, duodenal, or ampullary carcinomas that have not received any prior treatment for their disease. Dose escalation followed a standard 3 + 3 design, and dose-limiting toxicities (DLTs) were any treatment-related, first course non-hematologic grade ≥ 3 toxicity, except nausea/vomiting, or grade 4 hematologic toxicity. A dose expansion cohort in ABTC was treated at the MTD. Twenty-eight patients were enrolled and 4 dose levels were explored. The MTD was erlotinib 150 mg + GEM 800 mg/m 2  + OX 85 mg/m 2 . DLTs were diarrhea and anemia. Most frequent toxicities were nausea (78 %), fatigue (71 %), neuropathy (68 %), and diarrhea (61 %), predominantly grade 1-2. In the ABTC patients, the objective response and disease control rates were 29 % and 94 %, respectively, and median overall survival was 18 months. Erlotinib plus GEMOX was well tolerated. Encouraging anti-tumor activity was seen as evidenced by a high disease control rate and longer median OS than standard chemotherapy in the patients with ABTC., Competing Interests: Compliance with ethical standards Conflicts of interest LWG has served as a consultant for Celgene and has institutional research funding from Astellas Pharma, Pfizer, Onxy, SunPharma, Lilly, and Bristol-Myers Squibb.

Purpose: Cancer and cancer therapy-related neurocognitive changes negatively affect quality of life, yet few studies have examined neurocognitive changes in patients with head and neck cancer. The purpose of this study was to evaluate neurocognitive performance in patients with head and neck cancer at baseline before starting treatment and 3 months after treatment completion to assess treatment-associated changes in performance., Methods: Patients with head and neck cancer who were to receive primary or adjuvant chemoradiation (N = 55) underwent neuropsychological testing before and 3 months posttreatment. Changes in neurocognitive performance were assessed using a practice effect adjusted Reliable Change Index., Results: At baseline, 38 % of patients exhibited global neurocognitive impairment. Posttreatment, 21.8 % demonstrated declines in neurocognitive performance in at least one domain. Declines in domain-specific performance ranged from 1.8 to 12.7 % with the greatest decline in language, specifically verb retrieval. Domain-specific improvements ranged from 0 to 7.3 %., Conclusions: Patients had a high prevalence of baseline neurocognitive impairment. While neurocognitive performance posttreatment remained unchanged in the majority, almost 13 % suffered declines in language. Small percentages of patients exhibited improvements in their performance. Long-term effects and risk factors for neurocognitive decline in this population should be studied on a larger scale.

The European Society for Medical Oncology (ESMO) and the American Society of Clinical Oncology (ASCO) are publishing a new edition of the ESMO/ASCO Global Curriculum (GC) thanks to contribution of 64 ESMO-appointed and 32 ASCO-appointed authors. First published in 2004 and updated in 2010, the GC edition 2016 answers to the need for updated recommendations for the training of physicians in medical oncology by defining the standard to be fulfilled to qualify as medical oncologists. At times of internationalisation of healthcare and increased mobility of patients and physicians, the GC aims to provide state-of-the-art cancer care to all patients wherever they live. Recent progress in the field of cancer research has indeed resulted in diagnostic and therapeutic innovations such as targeted therapies as a standard therapeutic approach or personalised cancer medicine apart from the revival of immunotherapy, requiring specialised training for medical oncology trainees. Thus, several new chapters on technical contents such as molecular pathology, translational research or molecular imaging and on conceptual attitudes towards human principles like genetic counselling or survivorship have been integrated in the GC. The GC edition 2016 consists of 12 sections with 17 subsections, 44 chapters and 35 subchapters, respectively. Besides renewal in its contents, the GC underwent a principal formal change taking into consideration modern didactic principles. It is presented in a template-based format that subcategorises the detailed outcome requirements into learning objectives, awareness, knowledge and skills. Consecutive steps will be those of harmonising and implementing teaching and assessment strategies., Competing Interests: JBe received research support to Karolinska Institutet and University Hospital from Amgen, AstraZeneca, Bayer, Merck, Roche and Sanofi-Aventis.

These NCCN Guidelines Insights focus on recent updates to the 2015 NCCN Guidelines for Head and Neck (H&N) Cancers. These Insights describe the different types of particle therapy that may be used to treat H&N cancers, in contrast to traditional radiation therapy (RT) with photons (x-ray). Research is ongoing regarding the different types of particle therapy, including protons and carbon ions, with the goals of reducing the long-term side effects from RT and improving the therapeutic index. For the 2015 update, the NCCN H&N Cancers Panel agreed to delete recommendations for neutron therapy for salivary gland cancers, because of its limited availability, which has decreased over the past 2 decades; the small number of patients in the United States who currently receive this treatment; and concerns that the toxicity of neutron therapy may offset potential disease control advantages., (Copyright © 2015 by the National Comprehensive Cancer Network.)

Introduction: A combination of cetuximab and sorafenib in patients with recurrent and/or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) were assessed for potential benefit., Material and Methods: In a randomized phase II study, R/M HNSCC patients were treated with cetuximab 400mg/m(2) IV on day 1 followed by 250mg/m(2) IV weekly (Arm A), or cetuximab at the same dose/schedule plus sorafenib 400mg PO twice-a-day (Arm B). Each cycle was 21days. Tumor p16 and HPV status, and plasma immunomodulatory cytokine levels were assessed., Results: Of 55 patients enrolled (Arm A-27, Arm B-28), 52 patients received assigned treatments and 43 were evaluable for response. Overall response rate was 8% for both arms. Median overall survival (OS) and progression-free survival (PFS) were 9.0 and 3.0months in Arm A, and 5.7 and 3.2months in Arm B, respectively. Forty-four patients had tumors available for p16 staining (35-negative, 9-positive). Three of nine p16-positive tumors were also HPV positive. The p16-negative patients had significantly better PFS compared to the p16-positive patients (3.7 vs. 1.6months; p-value: 0.03), regardless of study arms. Twenty-four plasma samples were tested for 12 cytokine levels and patients with higher TGFβ1 levels had inferior PFS compared to lower levels (1.9 vs. 4.7months; adjusted p-value: 0.015), regardless of study arms., Conclusions: A subset of R/M patients with p16-negative tumors or lower plasma TGFβ1 levels had longer PFS given the cetuximab-based therapy. However, both arms showed only modest response and sorafenib given with cetuximab did not demonstrate clinical benefit., (Copyright © 2014 Elsevier Ltd. All rights reserved.)

This selection from the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Head and Neck Cancers focuses on glottic laryngeal cancer, which is the most common type of laryngeal cancer and has an excellent cure rate. The lymphatic drainage of the glottis is sparse, and early stage primaries rarely spread to regional nodes. Because hoarseness is an early symptom, most glottic laryngeal cancer is early stage at diagnosis. Updates to these guidelines for 2014 include revisions to "Principles of Radiation Therapy" for each site and "Principles of Surgery," and the addition of a new section on "Principles of Dental Evaluation and Management.", (Copyright © 2014 by the National Comprehensive Cancer Network.)

Sixty-six attending physicians at academic medical centers completed a 43-question self-assessment evaluating communication skills, comfort with clinical trial enrollment, and knowledge of patient-related barriers to enrollment on clinical trials. Responses and demographic information were analyzed for trends and for association with estimated trial enrollment. Physician-described enrollment of patients onto trials varied widely, with estimated enrollment varying from less than 5 patients to well over 125 enrolled during the previous year. Participants perceived themselves to have excellent communication skills and were comfortable with the trial enrollment process, though did not consistently identify patient-related barriers to enrollment. Physician knowledge of clinical trials currently enrolling within their field was associated with increased patient enrollment on study (p = 0.03). Academic physicians expressed confidence in their skills related to clinical trial enrollment despite less than ideal reported enrollment. Knowledge of clinical trials currently enrolling within a physician's specialty was associated with estimated patient enrollment, and may represent a correctable barrier to trial enrollment.

Background: Lymphedema may disrupt local function and affect quality of life (QOL) in patients with head and neck cancer. The purpose of this study was to examine the associations among severity of internal and external lymphedema, symptoms, functional status, and QOL in patients with head and neck cancer., Methods: The sample included 103 patients who were ≥ 3 months after head and neck cancer treatment. Variables assessed included severity of internal and external lymphedema, physical/psychological symptoms, functional status, and QOL., Results: Severity of internal and external lymphedema was associated with physical symptoms and psychological symptoms. Patients with more severe external lymphedema were more likely to have a decrease in neck left/right rotation. The combined effects of external and internal lymphedema severity were associated with hearing impairment and decreased QOL., Conclusions: Lymphedema severity correlates with symptom burden, functional status, and QOL in patients after head and neck cancer treatment., (Copyright © 2012 Wiley Periodicals, Inc.)

Background: Constitutive activation of nuclear factor κB (NF-κB) is associated with poor prognosis. Irinotecan demonstrates single-agent activity in head and neck cancer but activates NF-κB, promoting cell survival and resistance. Bortezomib is a proteasome inhibitor that inactivates NF-κB., Patients and Methods: We performed a randomized phase II trial of bortezomib on days 1, 4, 8, and 11 and irinotecan on days 1 and 8 of each 21-day cycle or single-agent bortezomib on days 1, 4, 8, and 11 on a 21-day cycle. The addition of irinotecan to bortezomib was allowed in patients who progressed on bortezomib alone., Results: The response rate of bortezomib and irinotecan was 13%. One patient had a partial response to bortezomib alone (response rate 3%). No responses were seen in patients with addition of irinotecan at time of progression on bortezomib., Conclusions: The bortezomib-based regimens evaluated in this study have minimal activity in recurrent or metastatic head and neck cancer., (Published 2012 Wiley Periodicals, Inc.)

Background: The prevalence, severity, and functional implications of adverse oral health outcomes attributed to head and neck cancer therapy are largely undefined. We report development of an oral health outcome subscale for the Vanderbilt Head and Neck Symptom Survey (VHNSS)., Methods: Oral health outcome questions were formulated through literature review and consultation with an expert panel. Questions were incorporated into the VHNSS resulting in a 50-item survey, scored 0 (none) to 10 (severe). The tool was administered to 70 subjects who completed radiation to assess for feasibility., Results: Patient acceptance was high with a completion time <10 minutes. A full range of scores was noted for 46 of 50 questions. Oral health symptom burden was high early and late posttreatment., Conclusions: The VHNSS version 2.0 was feasible and could be completed in a timely manner. Validation studies are ongoing. The high prevalence of adverse oral health outcomes warrants further study., (Copyright © 2011 Wiley Periodicals, Inc.)

Background: Polymorphism of the serotonin transporter gene, 5-HTTLPR (short allele) has been associated with depression. The purpose of this study was to show the evaluated depression in patients with head and neck cancer and a possible association with the 5-HTTLPR., Methods: The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (SCID for DSM-IV) was administered to 94 patients with head and neck cancer, of which 33 patients were genotyped for 5-HTTLPR. We also evaluated the prevalence of 5-HTTLPR polymorphism in 121 patients with head and neck cancer and 97 controls., Results: Forty-three percent of the patients met the criteria for a depressive diagnosis, 19% of which was new onset. In depressed patients, 85.7% (n = 12 of 14) had at least 1 short allele versus 68.4% (n = 13 of 19) of the patients without depressive diagnosis (p < .04). No difference was noted in the prevalence of the short allele in head and neck cancer cases versus controls (odds ratio = 0.8; p = .490)., Conclusion: Despite the high rate of depressive diagnosis, patients with head and neck cancer did not demonstrate a higher prevalence of this short allele of the 5-HTTLPR compared with a control population., (Copyright © 2011 Wiley Periodicals, Inc.)

Background: This phase 2 trial evaluated the tolerability and clinical efficacy of the combination of oxaliplatin and pemetrexed as an induction chemotherapy regimen in locally advanced head and neck squamous cell carcinoma (HNSCC)., Methods: Forty-two patients were enrolled in the study. Patients received pemetrexed 300 mg/m(2) intravenously (IV) and oxaliplatin 85 mg/m(2) IV every 14 days for a total of 4 cycles. A subset of patients consented to correlative studies including tumor tissue for human papillomavirus (HPV) detection and expression of DNA repair genes that may be predictive of response or resistance to oxaliplatin or pemetrexed., Results: Response data were available for 40 patients. Eighteen had a partial response, and 1 had a complete response, for a response rate of 47.5%. Patients with HPV(+) disease demonstrated superior response rates, progression-free survival, and overall survival. The regimen was well tolerated, with predominantly grade 1 or 2 alanine aminotransferase/aspartate aminotransferase elevation. One patient had grade 5 toxicity with neutropenia and sepsis. The authors did not identify genes predictive of response or toxicity, although HPV(+) tumors demonstrated a unique gene expression signature., Conclusions: Although the response rate of oxaliplatin and pemetrexed proved less than anticipated, the combination remains an active induction regimen in HNSCC. This regimen should be evaluated further in combination with targeted agents, such as cetuximab, especially in the HPV(+) patient population., (Copyright © 2011 American Cancer Society.)

Background: We describe the development and validation of the Vanderbilt Head and Neck Symptom Survey (VHNSS), which was designed to screen for tumor- and treatment-specific symptoms in patients with head and neck cancer undergoing concurrent chemoradiation (CCR)., Methods: Using a 2-step card sort method, we identified high-impact and high-frequency toxicities in patients with head and neck cancer treated with CCR. This resulted in a 28-item questionnaire which scores symptoms on a 0 to 10 scale (none to severe). The tool was validated using data collected from 5 supportive care studies comprising a total sample of 332 patients with head and neck cancer., Results: Responses to the VHNSS items demonstrated a very consistent pattern (Cronbach's alpha = 0.943) with each item contributing substantially to the global index. Five symptom subscales were identified including "Nutrition," "Pain," "Voice," "Swallow," and "Mucous/Dry Mouth." Each of the cluster scores demonstrated good internal consistency. The pattern of associations between the VHNSS and established tools indicated appropriate convergence and divergence. Comparison of global and subscale scores and objective measure were also in the expected direction providing further evidence of validity., Conclusions: The findings provide support that the VHNSS is a valid and reliable tool to assess head and neck-specific symptom burden and function loss. Further research to evaluate this screening tool as a part of a systems approach to supportive care is warranted.

Dysphagia is commonly seen in patients undergoing radiation-based therapy for locally advanced squamous carcinoma of the head and neck. Within 4 to 5 weeks of starting therapy, patients develop mucositis, radiation dermatitis, and edema of the soft tissues. Resulting pain, copious mucous production, xerostomia, and tissue swelling contribute to acute dysphagia. As the acute effects resolve, late effects including fibrosis, lymphedema, and damage to neural structures become manifest. Both acute and late effects result in adverse sequelae including aspiration, feeding tube dependence, and nutritional deficiencies. Early referral for evaluation by speech-language pathologists is critical to (1) ensure adequate assessment of swallow function, (2) determine whether further testing is needed to diagnose or treat the swallowing disorder, (3) generate a treatment plan that includes patient education and swallow therapy, (4) work with dieticians to ensure adequate and safe nutrition, and (5) identify patients with clinically significant aspiration.

Background: Patients with recurrent or metastatic HNC have a poor response and survival with currently available chemotherapy agents. Thus, new agents are needed. The authors report the results of a phase II trial of irinotecan and cisplatin in patients with metastatic or recurrent HNC., Methods: Patients were treated with irinotecan 65 mg/m2 IV over 90 minutes and cisplatin 30 mg/m2 were administered intravenously weekly for four weeks, followed by a two week rest. However, after 17 patients were treated with weekly irinotecan at a dose of 65 mg/m2, toxicity analysis demonstrated the poor tolerance of that dose in this patient population. Thus, the protocol was amended, and irinotecan was dose reduced to a starting dose of 50 mg/m2. Twenty-three additional patients were treated with this dose., Results: Forty patients were enrolled on study between February 2002 and April 2006, 17 patients at the first dose level and 23 patients at the amended dose level. Overall, 12 of 17 patients (71%) treated with irinotecan 65 mg/m2 experienced clinically significant grade 3 or 4 toxicity. Twelve patients required dose reductions. Toxicity was reduced but 17% of patients still experienced grade 3 or 4 toxicity on the lower irinotecan dose. The response rate was 35% for patients treated at irinotecan 65 mg/m2 and 22% for patients treated at 50 mg/m2. No complete responses were noted., Conclusions: The combination of irinotecan and cisplatin is efficacious in a poor prognosis group of patients but toxicity is substantial., ((Copyright) 2008 American Cancer Society.)

Combined-modality treatment of head and neck cancers, though linked to improved outcomes over earlier treatment methods, can be associated with acute and late adverse effects. These toxicities may lead to significant morbidity, increased mortality, and decreased quality of life. It is necessary to provide patients with adequate supportive-care measures in order to lessen suffering while maintaining the ability to deliver necessary doses of anticancer agents. The current review describes the pathology, assessment, and treatment options for cases of mucositis, impaired swallowing, nutritional and metabolic changes, xerostomia, radiation dermatitis, lymphedema, taste alterations, and pain, all of which may be associated with treatment of patients with head and neck cancers. Additionally, the pretreatment and during-treatment evaluation of dental health, as well as posttreatment dental care, are described.

The increased use of aggressive, combined modality therapy for the treatment of head and neck cancer has resulted in a marked increase in acute and late adverse effects. The acute effects of therapy have long been appreciated; however, it is now being recognized that the late effects of therapy result in a significant symptom burden, diminished functional capacity and decreased quality of survivorship. Furthermore, head and neck cancer has historically been considered a locoregional disease that is treated predominantly with locoregional therapy. It is now recognized that there are systemic effects of therapy that need to be considered. Potential systemic effects of therapy include: fatigue, weight loss, nutritional deficiencies, altered physical functioning and mood disorders. It is important for clinicians to be aware of these late effects in order to provide patients with appropriate support services and referrals. This paper examines the global and systemic effects of therapy.

The development of nucleoside analogues has had a major impact on cancer therapy. CS-682 is a novel, orally administered nucleoside analogue with a unique mechanism of action. CS-682 undergoes conversion to the active metabolite, CNDAC, which then leads to the inhibition of DNA polymerase and a novel "DNA self-strand breaking mechanism." We conducted a Phase I study of CS-682, administered orally five days per week in patients with refractory solid tumor malignancies. Forty-eight patients were enrolled on study. The recommended phase II dose of 30 mg/m(2) given orally once daily for 5 days a week for 4 weeks followed by 2 weeks off drug, was well tolerated. The most common dose limiting toxicity was neutropenia, which occurred at the highest dose levels of CS-682. This was correlated with higher CNDAC Cmax and AUC values. No tumor responses were noted in this heavily pretreated population. However, given the ease of administration and tolerability, further investigation of this agent is warranted.

In recent years, several therapeutic advances have been made in squamous cell carcinoma of the head and neck (SCCHN). However, despite multimodality therapy, patients with locally advanced SCCHN continue to demonstrate suboptimal 5-year survival rates. The addition of novel, targeted agents to traditional therapies holds promise for clinical benefit. This review will focus on new agents that are promising and their potential role in the treatment of SCCHN.

Background: Malignant tumors of the salivary glands make up approximately 5% of head and neck cancers. The Eastern Cooperative Oncology Group (ECOG) initiated a phase II evaluation of paclitaxel in patients with locally recurrent or metastatic salivary gland malignancies., Methods: Chemo-naive patients with histologically confirmed recurrent or metastatic carcinoma of salivary gland origin (mucoepidermoid, adenocarcinoma, or adenoid cystic) were eligible. Patients were treated with paclitaxel, 200 mg/m(2) IV, every 21 days for a minimum of four cycles., Results: Forty-five patients were treated. Eight partial responses were seen among the 31 patients with mucoepidermoid or adenocarcinoma histologic findings for a response rate of 26%. No responses were seen in the adenoid cystic carcinoma group. No significant difference in overall survival was found among these three histologic subgroups., Conclusion: Paclitaxel demonstrates moderate activity in salivary gland tumors of mucoepidermoid and adenocarcinoma histology. The poor response rate in adenoid cystic carcinoma is consistent with prior reports in this chemoresistant histologic subtype., ((c) 2005 Wiley Periodicals, Inc.)

Myeloid suppressor cells (MSCs) producing high levels of arginase I block T cell function by depleting l-arginine in cancer, chronic infections, and trauma patients. In cancer, MSCs infiltrating tumors and in circulation are an important mechanism for tumor evasion and impair the therapeutic potential of cancer immunotherapies. However, the mechanisms that induce arginase I in MSCs in cancer are unknown. Using the 3LL mouse lung carcinoma, we aimed to characterize these mechanisms. Arginase I expression was independent of T cell-produced cytokines. Instead, tumor-derived soluble factors resistant to proteases induced and maintained arginase I expression in MSCs. 3LL tumor cells constitutively express cyclooxygenase (COX)-1 and COX-2 and produce high levels of PGE2. Genetic and pharmacological inhibition of COX-2, but not COX-1, blocked arginase I induction in vitro and in vivo. Signaling through the PGE2 receptor E-prostanoid 4 expressed in MSCs induced arginase I. Furthermore, blocking arginase I expression using COX-2 inhibitors elicited a lymphocyte-mediated antitumor response. These results demonstrate a new pathway of prostaglandin-induced immune dysfunction and provide a novel mechanism that can help explain the cancer prevention effects of COX-2 inhibitors. Furthermore, an addition of arginase I represents a clinical approach to enhance the therapeutic potential of cancer immunotherapies.

Purpose: To characterize the pharmacokinetic behavior of 5-azacitidine (5-AC), a cytidine nucleoside analog, when given with phenylbutyrate, a histone deaceytlase inhibitor., Patients and Methods: Pharmacokinetic data were obtained from two trials involving patients with solid tumor and hematologic malignancies. 5-AC at doses ranging from 10 to 75 mg/m2/d was administered once daily as a subcutaneous injection for 5 to 21 days in combination with phenylbutyrate administered as a continuous intravenous infusion for varying dose and duration every 28 or 35 days. Serial plasma samples were collected up to 24 hours after 5-AC administration. 5-AC was quantitated using a validated liquid chromatograph/tandem mass spectrometry method., Results: 5-AC was rapidly absorbed with the mean T(max) occurring at 0.47 hour. Average maximum concentration (C(max)) and area under the curve (AUC(0-infinity)) values increased in a dose-proportionate manner with increasing dose from 10 to 75 mg/m2/d; the mean +/- SD C(max) and AUC(0-infinity) at 10 mg/m2/d were 776 +/- 459 nM and 1,355 +/- 1,125 h*nM, respectively, and at 75 mg/m2/d were 4,871 +/- 1,398 nM and 6,582 +/- 2,560 h*nM, respectively. Despite a short terminal half-life of 1.5 +/- 2.3 hours, inhibition of DNA methyl transferase activity in tumors of patients receiving 5-AC has been documented., Conclusion: 5-AC is rapidly absorbed and eliminated when administered subcutaneously. Sufficient 5-AC exposure is achieved to produce pharmacodynamic effects in tumors.

The optimal regimen for organ preservation for laryngeal cancer remains an area of active investigation. Multiple organ-preservation strategies have been explored, including radiation therapy alone, induction chemotherapy followed by radiation therapy, and concomitant chemoradiotherapy. Until recently, induction chemotherapy followed by radiation therapy was the standard of care for organ preservation in the United States. However, recent data from the Intergroup Trial, R 91-11 has placed concomitant chemoradiotherapy in the forefront as the standard of care for organ preservation. Newer strategies are being investigated and include the use of induction chemotherapy before concomitant chemoradiotherapy and the integration of novel biological agents. It remains to be seen whether such interventions can improve on the excellent locoregional control shown in the landmark Intergroup trial.

Essential thrombocytosis is one of the chronic myeloproliferative disorders that includes polycythemia vera, chronic myelogenous leukemia, and agnogenic myeloid metaplasia. Despite established diagnostic criteria and greater than a quarter century of study, there are still several diagnostic and management dilemmas that plague researchers and clinicians alike. We present a case of essential thrombocytosis in a patient with multiple sequelae.

Organ-preservation strategies include definitive radiation therapy alone, induction chemotherapy followed by radiotherapy, and concurrent chemoradiotherapy. Over the past decade, induction chemotherapy followed by radiotherapy has been the standard for the nonsurgical management of advanced laryngeal cancer. Over this same period, however, other nonsurgical strategies have been under evaluation. These approaches include radiotherapy with concurrent chemotherapy to take advantage of the radiosensitizing properties of most cytotoxic drugs with activity against squamous cell cancer, altered fractionation radiotherapy, and the incorporation of molecularly targeted therapeutics into multimodality treatment.
