Patterns of neurological adverse events among a retrospective cohort of patients receiving immune checkpoint inhibitors.

Aim: Neurological adverse events (NAEs) are infrequent immune checkpoint inhibitor (ICI) outcomes poorly characterized in extant research, complicating their clinical management. Methods: This study characterized the frequency, severity, patterning and timing of NAEs using a large retrospective registry, including all patients who received at least one dose of an ICI from 2/1/2011-4/7/2022 within our health network. Results: Among 3137 patients, there were 54 NAEs (1.72% any grade; 0.8% grade 3-4). Most NAEs were peripheral (57.4%) versus central (42.6%). Melanoma and renal cell carcinoma were significantly associated with NAEs. Conclusion: The incidence of NAEs was rare though higher than many prior case estimates; the timing was consistent with other AEs. NAEs frequently occurred in tumor types known to favor brain metastases.

Immune checkpoint inhibitors are new drugs for cancer. They boost your body's defenses to fight cancer cells. These drugs can be used alone or with other cancer treatments. Most people are okay with these medicines, but some might have problems in different parts of the body. This can be tricky to figure out. Rarely, there can be issues in the brain or nerves. These side effects are rare, happening in about 2 in every 100 people who use the drugs. They are more common in certain cancers like melanoma and kidney cancer. As doctors learn more about these side effects, they can better predict, treat, and prevent them.

Study protocol: phase II study to evaluate the effect of cetuximab monotherapy after immunotherapy with PD-1 inhibitors in patients with head and neck squamous cell cancer.

Background: Immunotherapy with programmed death receptor-1 (PD-1) inhibitors, as a single agent or in combination with chemotherapy, is the standard first-line treatment for recurrent or metastatic head and neck squamous cell cancer (R/M HNSCC). Unfortunately, there is no established second-line treatment for the many patients who fail immunotherapy. Cetuximab is the only targeted therapy approved in HNSCC but historically has a low response rate of 13%. Objectives: We hypothesize that cetuximab monotherapy following an immune checkpoint inhibitor (ICI) will lead to increased efficacy due to a potential synergistic effect on the antitumor immune response, as a result of activation effects of both treatments on innate and adaptative immune responses. To the authors' knowledge, this is the only ongoing prospective clinical study that evaluates the combination of cetuximab and ICIs administered sequentially. Methods and analysis: In this non-randomized, open-label, phase II trial, 30 patients with R/M HNSCC who have previously failed or could not tolerate a PD-1 inhibitor as a single agent or in combination with chemotherapy will subsequently be treated with cetuximab monotherapy. Outcomes of interest include overall response rate, duration of response, progression-free survival, overall survival, and treatment toxicity, as well as treatment outcome measured by a patient-reported outcome questionnaire. Saliva and blood will be collected for correlative studies to investigate the immune response status at the end of therapy with an ICI and the effect of cetuximab on the antitumor immune response. The results will be correlated with the response to cetuximab and the time window between the last administration of an ICI and the loading dose of cetuximab. The clinical study is actively recruiting. Ethics: This study was approved by the Wake Forest Comprehensive Cancer Center Institutional Review Board: IRB00065239. Clinical trial registration: This study is registered on ClinicalTrials.gov: NCT04375384.

The Association Between an Electronic Health Record (EHR)-Embedded Frailty Index and Patient-Reported Outcomes Among Patients with Metastatic Non-Small-Cell Lung Cancer on Immunotherapy: A Brief Report.

Background: While frailty is a well-established predictor of overall mortality among patients with metastatic non-small cell lung cancer (mNSCLC), its association with patient-reported outcomes is not well-characterized. The goal of this study was to examine the association between an electronic frailty index (eFI) score and patient-reported outcome measures along with prognostic awareness among patients with mNSCLC receiving immunotherapy. Methods: In a cross-sectional study, patients with mNSCLC who were on immunotherapy completed the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30) and the National Cancer Institute Patient Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). We utilized bivariate analyses to compare quality of life, symptoms, supportive services, and prognostic awareness among 3 groups defined by e-frailty status. Results: Sixty patients (mean age 62.5 years, 75% Caucasian, 60% women) participated. Most patients were pre-frail (68%), with 13% being frail and 18% non-frail. Pre-frail and frail patients had significantly lower physical function scores (mean 83.9 fit vs 74.8 pre-frail vs 60.0 frail, P = .04) and higher rates of self-reported pain (75% frail vs 41.5% pre-frail vs 18.2% fit; P = .04) compared to non-frail patients. We found no differences in palliative referral rates. Conclusion: Pre-frail and frail mNSCLC patients identified by the eFI have higher rates of pain and physical functional impairments than non-frail patients. These findings highlight the importance of emphasizing preventive interventions targeting social needs, functional limitations, and pain management, especially among pre-frail patients to reduce further decline.

Quad-shot-immunotherapy: quad-shot radiotherapy with pembrolizumab for advanced/recurrent head and neck cancer.

Effective treatments for advanced/recurrent head and neck squamous-cell carcinoma are limited. For cases not curable by conventional local therapies, the immune checkpoint inhibitor pembrolizumab shows modest response rates. Quad-shot, a hypofractionated palliative radiotherapy regimen (14.8 Gy in four twice-daily fractions), can provide symptomatic relief, contributes to local control and may potentiate the effects of immune checkpoint inhibitors. In this study, 15 patients with advanced/recurrent head and neck squamous-cell carcinoma will be treated with pembrolizumab combined with up to three administrations of quad-shot before cycles four, eight and 13. Outcomes include disease response, survival and treatment toxicity. Correlative multiomics analysis of blood and saliva will identify molecular biomarkers of response to immune checkpoint inhibitor and the immune-related impact of quad-shot. Clinical trial registration: This study (WFBCCC 60320) is registered on NCT04454489 (ClinicalTrials.gov).

Advanced and recurrent head and neck cancers are difficult to treat. Most patients receive systemic therapies, such as chemotherapy or immunotherapy, with modest rates of cancer control. We aim to test the effectiveness of an immunotherapy drug called pembrolizumab in combination with a type of low-dose radiation therapy called quad-shot. Patients will receive pembrolizumab every 3 weeks and will be treated with one to three low-dose radiation therapy courses targeted at their cancer in the head and neck approximately every 12 weeks. We plan to measure how well the cancer responds to treatment, how long this response lasts, how long patients survive and treatment side effects.

Prognostic Awareness, Palliative Care Use, and Barriers to Palliative Care in Patients Undergoing Immunotherapy or Chemo-Immunotherapy for Metastatic Lung Cancer.

Background and Objectives: This study describes patients' prognostic awareness and palliative care use in the setting of immunotherapy for metastatic non-small cell lung cancer (mNSCLC). Design: We surveyed 60 mNSCLC patients receiving immunotherapy at a large academic medical center; conducted follow-up interviews with 12 survey participants; and abstracted palliative care use, advance directive completion, and death within a year of survey completion from the medical record. Results: Forty seven percent of patients surveyed thought they would be cured; 83% were not interested in palliative care. Interviews suggested oncologists emphasized therapeutic options when discussing prognosis and that commonly used descriptions of palliative care may exacerbate misperceptions. Only 7% had received outpatient palliative care and 8% had an advance directive a year after the survey; only 16% of the 19 patients who died had received outpatient palliative care. Conclusions: Interventions are needed to facilitate prognostic discussions and outpatient palliative care during immunotherapy. Clinical Trial Registration Number NCT03741868.

Team-Based Hospice Referrals: A Potential Quality Metric for Lung Cancer in the Immunotherapy Era.

BACKGROUND: Immune checkpoint inhibitors (ICIs) can lead to durable responses in patients with lung cancer but may delay transitions to hospice at the end of life (EOL). We aimed to test the association of continuity of care with EOL outcomes in the ICI era. METHODS: We collected retrospective data on all patients with lung cancer who started ICI treatment at a single comprehensive cancer center in the United States (1/1/14-5/1/18) and subsequently died. We defined a hospice referral as having continuity of care if placed by a provider from the patient's multidisciplinary cancer team (e.g., a medical oncologist, palliative care specialist, intensivist, and hospitalist). RESULTS: In this cohort of 143 patients, 58% had a team-based hospice referral which was associated with a lower risk of death in the hospital. The most common reason patients declined hospice at EOL was an unwillingness to discontinue cancer-directed therapy. As compared to a similar historical cohort of patients treated with chemotherapy alone (2008-2010), there was a similar rate of hospice referral (68% vs 74%) but higher rates of new systemic therapy initiated within 30 days of death (17% vs 6%, p .001) and last dose within 14 days of death (13% vs 5%, p .005). CONCLUSIONS: Future studies should test the continuity of care at EOL as a new quality metric for advanced NSCLC.

A Case Report of Immune Checkpoint Inhibitor-Induced Aortitis Treated with Tocilizumab.

Vasculitic immune checkpoint inhibitor-related adverse events (irAEs) are rare, with limited data to guide their management. Here, we present a case of a 67-year-old female with stage IV cutaneous melanoma who received first-line pembrolizumab. She had completed 21 cycles of pembrolizumab dosed at 200 mg every 21 days over 15 months when she developed fatigue, chills, decreased appetite, night sweats, nausea, diarrhea, dry cough, and chest pain. A routine, staging positron emission tomography (PET) scan revealed aortitis of the transverse aortic arch. An extensive workup was unremarkable for other causes, so her condition was labeled a grade III immune-related vasculitis. Based on this diagnosis, we started high-dose prednisone and discontinued pembrolizumab. After two months of high-dose prednisone, she developed bothersome weight gain and insomnia, leading to a switch from prednisone to tocilizumab as a steroid-sparing agent. The selection of tocilizumab was based on its routine use for giant cell arteritis which can have extracranial symptoms including thoracic aortitis. Her symptoms resolved, and subsequent PET scans showed resolution of the aortitis and no evidence of metastatic melanoma. As the indications for immunotherapy expand, rare complications are becoming more prevalent, and more data will be needed to guide their management. While there is evidence for tocilizumab use as a steroid-sparing treatment for large-vessel vasculitides due to other conditions, this is the first case of its use to treat an aortitis irAE to our knowledge. In this case, it was an effective means of treating the patient while sparing them from prolonged corticosteroids.

Early [18]FDG PET/CT scan predicts tumor response in head and neck squamous cell cancer patients treated with erlotinib adjusted per smoking status.

Translational Relevance: Evaluation of targeted therapies is urgently needed for the majority of patients with metastatic/recurrent head and neck squamous cell carcinoma (HNSCC) who progress after immunochemotherapy. Erlotinib, a targeted inhibitor of epidermal growth factor receptor pathway, lacks FDA approval in HNSCC due to inadequate tumor response. This study identifies two potential avenues to improve tumor response to erlotinib among patients with HNSCC. For the first time, this study shows that an increased erlotinib dose of 300 mg in smokers is well-tolerated and produces similar plasma drug concentration as the regular dose of 150 mg in non-smokers, with increased study-specific defined tumor response. The study also highlights the opportunity for improved patient selection for erlotinib treatment by demonstrating that early in-treatment [18]FDG PET/CT is a potential predictor of tumor response, with robust statistical correlations between metabolic changes on early in-treatment PET (4-7 days through treatment) and anatomic response measured by end-of-treatment CT. Purpose: Patients with advanced HNSCC failing immunochemotherapy have no standard treatment options. Accelerating the investigation of targeted drug therapies is imperative. Treatment with erlotinib produced low response rates in HNSCC. This study investigates the possibility of improved treatment response through patient smoking status-based erlotinib dose optimization, and through early in-treatment [18]FDG PET evaluation to differentiate responders from non-responders. Experimental design: In this window-of-opportunity study, patients with operable HNSCC received neoadjuvant erlotinib with dose determined by smoking status: 150 mg (E150) for non-smokers and 300 mg (E300) for active smokers. Plasma erlotinib levels were measured using mass spectrometry. Patients underwent PET/CT before treatment, between days 4-7 of treatment, and before surgery (post-treatment). Response was measured by diagnostic CT and was defined as decrease in maximum tumor diameter by ≥ 20% (responders), 10-19% (minimum-responders), and < 10% (non-responders). Results: Nineteen patients completed treatment, ten of whom were smokers. There were eleven responders, five minimum-responders, and three non-responders. Tumor response and plasma erlotinib levels were similar between the E150 and E300 patient groups. The percentage change on early PET/CT and post-treatment PET/CT compared to pre-treatment PET/CT were significantly correlated with the radiologic response on post-treatment CTs: R=0.63, p=0.0041 and R=0.71, p=0.00094, respectively. Conclusion: This pilot study suggests that early in-treatment PET/CT can predict response to erlotinib, and treatment with erlotinib dose adjusted according to smoking status is well-tolerated and may improve treatment response in HNSCC. These findings could help optimize erlotinib treatment in HNSCC and should be further investigated.

Intensity-modulated radiotherapy with planned Gamma Knife radiosurgery boost for head and neck cancer with extensive disease in proximity to critical structures.

BACKGROUND: To describe intensity-modulated radiotherapy (IMRT) with Gamma Knife Radiosurgery (GKRS) boost for locally advanced head and neck cancer (HNC) with disease near dose-limiting structures. METHODS: Patients with HNC treated with IMRT/GKRS as part of a combined modality approach between 2011 and 2021 were reviewed. Local control, overall survival and disease-specific survival were estimated using the Kaplan Meier method. RESULTS: Twenty patients were included. Nineteen patients had T3-4 tumors. Median follow-up was 26.3 months. GKRS site control was 95%. Two patients progressed at the treated primary site, one patient failed at the edge of the GKRS treatment volume, with no perineural or intracranial failure. 2-year OS was 94.7% (95% CI: 85.2%-100%). Concurrent chemotherapy was given in nine patients (45%). One patient (5%) received induction/concurrent chemotherapy. Brain radionecrosis occurred in three patients, one of which was biopsy-proven. CONCLUSIONS: IMRT plus GKRS boost results in excellent disease control near critical structures with minimal toxicity.

Just-in-Time Teaching (JiTT) Screencasts: a Randomized Controlled Trial of Asynchronous Learning on an Inpatient Hematology-Oncology Teaching Service.

BACKGROUND: The efficacy of just-in-time teaching (JiTT) screencasts for graduate medical education on an inpatient adult hematology-oncology service (HOS) setting is not known. Our preceding pilot data identified six high-yield topics for this setting. The study objective was to evaluate screencast educational efficacy. METHODS: Internal medicine residents scheduled to start a rotation on the primary HOS of an academic medical center were eligible for this parallel, unblinded, randomized controlled trial with concealed allocation. Participants underwent block randomization to the usual educational curriculum either with or without access to a series of novel screencasts; all participants received an anonymous online end-of-rotation survey and a $20 gift certificate upon completion. The primary outcome was the change in attitude among learners, measured as their self-reported confidence for managing the clinical topics. RESULTS: From 12/9/2019 through 6/15/2020, accrual was completed with 67 of 78 eligible residents (86%) enrolled and randomized. Analysis was by intention-to-treat and participant response rate was 91%. Sixty-four percent of residents in the treatment arm rated their clinical management comfort level as "comfortable" or "very comfortable" versus 21% of residents in the usual education arm (p = 0.001), estimated difference = 43% (95% CI: 21-66%), using a prespecified cumulative cutoff score. Treatment arm participants reported that the screencasts improved medical oncology knowledge base (100%), would improve their care for cancer patients (92%), and had an enjoyable format (96%). CONCLUSION: Residents on a busy inpatient HOS found that a JiTT screencast increased clinical comfort level in the management of HOS-specific patient problems.

Chemoradiotherapy with high-dose cisplatin compared with weekly cisplatin for locally advanced head and neck squamous cell carcinoma.

INTRODUCTION: Concurrent chemoradiotherapy (CRT) using high-dose cisplatin (HDC) is standard for patients with locally advanced head and neck squamous cell carcinoma (HNSCC); weekly cisplatin (WC) is an alternative. We aim to compare retrospectively the survival and disease control outcomes between these regimens in our institutional experience. METHODS: Patients with stage III-IV HNSCC treated with definitive or postoperative CRT between 2012 and 2018 were identified. Patients were stratified by intent-to-treat CRT. Overall survival (OS) and disease-free survival (DFS) were generated and multivariable Cox models were performed. RESULTS: 193 patients were treated with concurrent HDC (n = 69), WC at 40 mg/m2 (WC40, n = 88) or WC at <40 mg/m2 (WC<40, n = 36). Treatment intent was definitive in 74% and adjuvant in 26%. Baseline differences included age, performance status and HPV status. Cumulative cisplatin dose ≥200 mg/m2 was achieved in 89% (HDC), 86% (WC40) and 25% (WC<40, P < 0.0001). For HDC, WC40 and WC<40, 2-year OS rates were 87%, 77%, 60% and 2-year DFS rates were 75%, 68% and 52%, respectively. Multivariable analysis revealed gender, performance status, primary site, T/N stage and chemotherapy as predictive of OS. Primary site, T/N stage and chemotherapy regimen were associated with DFS. Compared with HDC, no differences in locoregional control (LRC) or distant metastasis were observed between groups. CONCLUSION: Concurrent HDC is associated with increased total cisplatin intensity, OS and DFS compared with weekly cisplatin regimens. LRC was not associated with chemotherapy regimen. HDC remains the standard of care; WC40 is a reasonable alternative that does not appear to sacrifice LRC.

What Oncologists Want: Identifying Challenges and Preferences on Diagnosis Data Entry to Reduce EHR-Induced Burden and Improve Clinical Data Quality.

PURPOSE: Accurate recording of diagnosis (DX) data in electronic health records (EHRs) is important for clinical practice and learning health care. Previous studies show statistically stable patterns of data entry in EHRs that contribute to inaccurate DX, likely because of a lack of data entry support. We conducted qualitative research to characterize the preferences of oncological care providers on cancer DX data entry in EHRs during clinical practice. METHODS: We conducted semistructured interviews and focus groups to uncover common themes on DX data entry preferences and barriers to accurate DX recording. Then, we developed a survey questionnaire sent to a cohort of oncologists to verify the generalizability of our initial findings. We constrained our participants to a single specialty and institution to ensure similar clinical backgrounds and clinical experience with a single EHR system. RESULTS: A total of 12 neuro-oncologists and thoracic oncologists were involved in the interviews and focus groups. The survey developed from these two initial thrusts was distributed to 19 participants yielding a 94.7% survey response rate. Clinicians reported similar user interface experiences, barriers, and dissatisfaction with current DX entry systems including repetitive entry operations, difficulty in finding specific DX options, time-consuming interactions, and the need for workarounds to maintain efficiency. The survey revealed inefficient DX search interfaces and challenging entry processes as core barriers. CONCLUSION: Oncologists seem to be divided between specific DX data entry and time efficiency because of current interfaces and feel hindered by the burdensome and repetitive nature of EHR data entry. Oncologists' top concern for adopting data entry support interventions is ensuring that it provides significant time-saving benefits and increasing workflow efficiency. Future interventions should account for time efficiency, beyond ensuring data entry effectiveness.

Unmet Care Needs and Financial Hardship in Patients With Metastatic Non-Small-Cell Lung Cancer on Immunotherapy or Chemoimmunotherapy in Clinical Practice.

PURPOSE: Immunotherapy or chemoimmunotherapy is now standard treatment for most patients with metastatic non-small-cell lung cancer (mNSCLC), yet patient supportive care needs (SCNs) on immunotherapy are not well defined. This study characterized the SCNs and financial hardship of patients with mNSCLC treated with immunotherapy or chemoimmunotherapy and examined the relationship between patient and caregiver cancer-related employment reductions and patient financial hardship. METHODS: Patients with mNSCLC on immunotherapy or chemoimmunotherapy from a single academic medical center completed the SCNs Survey-34, items indexing material, psychological, and behavioral financial hardship, and the Comprehensive Score for Financial Toxicity. Univariate and bivariate analyses examined care needs, financial hardship, and impact of cancer-related employment reductions on patient financial hardship. RESULTS: Sixty patients (40% male; 75% White, mean age = 62.5 years, 57% on immunotherapy alone) participated. Fifty-five percent reported unmet needs in physical or daily living and psychological domains. Financial hardship was common (33% material, 63% psychological, and 57% behavioral). Fifty-two percent reported hardship in at least two domains. Forty percent reported a caregiver cancer-related employment reduction. Caregiver employment reduction was related to patient financial hardship (68% of those reporting caregiver employment reduction reported at least two domains of hardship v 40% of those without reduction, P = .03) and patient financial distress (mean Comprehensive Score for Financial Toxicity = 19.6 among those with caregiver employment reduction v 26.8 without, P = .01). CONCLUSION: Patients with mNSCLC treated with immunotherapy or chemoimmunotherapy report multiple unmet care needs and financial hardship. Psychological, functional, financial, and caregiver concerns merit assessment and intervention in this population.

SMARCA4 mutations in KRAS-mutant lung adenocarcinoma: a multi-cohort analysis.

KRAS is a key oncogenic driver in lung adenocarcinoma (LUAD). Chromatin-remodeling gene SMARCA4 is comutated with KRAS in LUAD; however, the impact of SMARCA4 mutations on clinical outcome has not been adequately established. This study sought to shed light on the clinical significance of SMARCA4 mutations in LUAD. The association of SMARCA4 mutations with survival outcomes was interrogated in four independent cohorts totaling 564 patients: KRAS-mutant patients with LUAD who received nonimmunotherapy treatment from (a) The Cancer Genome Atlas (TCGA) and (b) the MSK-IMPACT Clinical Sequencing (MSK-CT) cohorts; and KRAS-mutant patients with LUAD who received immune checkpoint inhibitor-based immunotherapy treatment from (c) the MSK-IMPACT (MSK-IO) and (d) the Wake Forest Baptist Comprehensive Cancer Center (WFBCCC) immunotherapy cohorts. Of the patients receiving nonimmunotherapy treatment, in the TCGA cohort (n = 155), KRAS-mutant patients harboring SMARCA4 mutations (KS) showed poorer clinical outcome [P = 6e-04 for disease-free survival (DFS) and 0.031 for overall survival (OS), respectively], compared to KRAS-TP53 comutant (KP) and KRAS-only mutant (K) patients; in the MSK-CT cohort (n = 314), KS patients also exhibited shorter OS than KP (P = 0.03) or K (P = 0.022) patients. Of patients receiving immunotherapy, KS patients consistently exhibited the shortest progression-free survival (PFS; P = 0.0091) in the MSK-IO (n = 77), and the shortest PFS (P = 0.0026) and OS (P = 0.0014) in the WFBCCC (n = 18) cohorts, respectively. Therefore, mutations of SMARCA4 represent a genetic factor leading to adverse clinical outcome in lung adenocarcinoma treated by either nonimmunotherapy or immunotherapy.

Nicotine promotes brain metastasis by polarizing microglia and suppressing innate immune function.

Up to 40% of lung cancer patients develop brain metastasis, and the median survival of these patients remains less than 6 months. Smoking is associated with lung cancer. However, how smoking impacts the development of brain metastasis remains elusive. We examined 281 lung cancer patients with distant metastasis and found that smokers exhibited a significantly high incidence of brain metastasis. We found that nicotine enhanced brain metastasis, while a depletion of microglia suppressed this effect in vivo. Nicotine skewed the polarity of microglia to the M2 phenotype, thereby increasing the secretion of IGF-1 and CCL20, which promoted tumor progression and stemness. Importantly, nicotine enhanced the expression of SIRPα in microglia and restricted their phagocytic ability. We also identified a compound, parthenolide, that suppressed brain metastasis by blocking M2 polarization. Our results indicate that nicotine promotes brain metastasis by skewing the polarity of M2 microglia, which enhances metastatic tumor growth. Our results also highlight a potential risk of using nicotine for tobacco cessation.

Workflow Differences Affect Data Accuracy in Oncologic EHRs: A First Step Toward Detangling the Diagnosis Data Babel.

PURPOSE: Diagnosis (DX) information is key to clinical data reuse, yet accessible structured DX data often lack accuracy. Previous research hints at workflow differences in cancer DX entry, but their link to clinical data quality is unclear. We hypothesized that there is a statistically significant relationship between workflow-describing variables and DX data quality. METHODS: We extracted DX data from encounter and order tables within our electronic health records (EHRs) for a cohort of patients with confirmed brain neoplasms. We built and optimized logistic regressions to predict the odds of fully accurate (ie, correct neoplasm type and anatomic site), inaccurate, and suboptimal (ie, vague) DX entry across clinical workflows. We selected our variables based on correlation strength of each outcome variable. RESULTS: Both workflow and personnel variables were predictive of DX data quality. For example, a DX entered in departments other than oncology had up to 2.89 times higher odds of being accurate (P < .0001) compared with an oncology department; an outpatient care location had up to 98% fewer odds of being inaccurate (P < .0001), but had 458 times higher odds of being suboptimal (P < .0001) compared with main campus, including the cancer center; and a DX recoded by a physician assistant had 85% fewer odds of being suboptimal (P = .005) compared with those entered by physicians. CONCLUSION: These results suggest that differences across clinical workflows and the clinical personnel producing EHR data affect clinical data quality. They also suggest that the need for specific structured DX data recording varies across clinical workflows and may be dependent on clinical information needs. Clinicians and researchers reusing oncologic data should consider such heterogeneity when conducting secondary analyses of EHR data.

Neuromuscular ultrasound for taxane peripheral neuropathy in breast cancer.

BACKGROUND: Our study aim was to evaluate neuromuscular ultrasound (NMUS) for the assessment of taxane chemotherapy-induced peripheral neuropathy (CIPN), the dose-limiting toxicity of this agent. METHODS: This cross-sectional study of breast cancer patients with taxane CIPN measured nerve cross-sectional area (CSA) by NMUS and compared with healthy historical controls. Correlations were determined between CSA and symptom scale, nerve conduction studies, and intraepidermal nerve fiber density (IENFD). RESULTS: A total of 20 participants reported moderate CIPN symptoms at a median of 3.8 months following the last taxane dose. Sural nerve CSA was 1.2 mm2 smaller than healthy controls (P ≤ .01). Older age and time since taxane were associated with smaller sural nerve CSA. For each 1 mm2 decrease in sural nerve CSA, distal IENFD decreased by 2.1 nerve/mm (R2 0.30; P = .04). CONCLUSIONS: These data support a sensory predominant taxane neuropathy or neuronopathy and warrant future research on longitudinal NMUS assessment of CIPN.

Patient-Reported Outcomes From Patients Receiving Immunotherapy or Chemoimmunotherapy for Metastatic Non-Small-Cell Lung Cancer in Clinical Practice.

INTRODUCTION: Immunotherapy and chemoimmunotherapy clinical trials for metastatic non-small-cell lung cancer (mNSCLC) have generally excluded patients with poor performance status (PS) and have utilized patient-reported measures that could miss some symptoms associated with immunotherapy. The goals of this study were to describe quality of life and symptom burden among mNSCLC patients receiving immunotherapy in clinical practice, and to examine burden by Eastern Cooperative Oncology Group performance status (ECOG PS) and age. PATIENTS AND METHODS: Between 2017 and 2018, mNSCLC patients receiving immuno/chemoimmunotherapy at an academic medical center completed the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30) and the National Cancer Institute Patient Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). Univariate and bivariate analyses described EORTC-QLQ-C30 subscales and the proportion reporting at least moderate PRO-CTCAE symptoms, and compared scores by ECOG PS (0/1 vs. 2/3) and age (< 70 vs. ≥ 70 years). RESULTS: Sixty patients (60% female; 75% < 70 years old; 68% ECOG PS 0/1; 57% receiving single-agent immunotherapy) participated. The mean EORTC-QLQ-C30 global health score was 62.6; EORTC symptoms were highest for fatigue, insomnia, dyspnea, and financial concerns (all > 30). Global health and pain were worse in ECOG PS 2/3 patients. For PRO-CTCAE, 20% to 40% reported at least moderate gastrointestinal, respiratory, dermatologic, arthralgia, or myalgia symptoms. The PRO-CTCAE pain score was higher among ECOG PS 2/3 patients. CONCLUSION: In clinical practice, global health was largely comparable to published clinical trials, but PRO-CTCAE items indicated a higher symptom prevalence. Closer monitoring of symptoms is warranted in ECOG PS 2/3 patients.

Human papillomavirus-associated squamous cell carcinoma of the larynx or hypopharynx: Clinical outcomes and implications for laryngeal preservation.

OBJECTIVES: Human papillomavirus (HPV) can be detected in approximately 25% of squamous cell carcinomas (SCC) of the larynx and hypopharynx. Though HPV is associated with improved survival and disease control in patients with oropharyngeal SCC, the role of HPV as a marker of favorable treatment outcomes in laryngeal and hypopharyngeal cancer is unclear. MATERIALS AND METHODS: Patients treated for laryngeal or hypopharyngeal SCC were reviewed. HPV status detected by p16 and/or HPV DNA PCR were abstracted from the medical record. A subset of samples (stage III-IV treated with primary radiotherapy) was retrospectively tested for p16 and HPV DNA. Overall survival (OS), disease-free survival (DFS), and locoregional control (LRC) were determined and compared between HPV-positive (p16+, PCR+ or both) and HPV-negative (p16- or PCR-) patients. RESULTS: In total, 279 patients were identified, 94 of which were tested for HPV. Eighty-two (87%) were negative and 12 (13%) were positive for HPV. At 3 years, there were no significant differences in OS (72% v. 83%), DFS (60% v. 71%) and LRC (80% v. 89%). Performance status, smoking history and stage predicted for OS, while performance status and stage predicted for DFS. Analysis of patients treated with primary radiotherapy revealed non-significantly higher rates of laryngeal preservation at 3 years (75% v. 100%). CONCLUSION: HPV was detected in 13% of tested laryngeal/hypopharyngeal cancers. HPV does not appear to significantly impact survival or disease control in patients with SCC of the larynx or hypopharynx. Non-significant improvements in laryngeal preservation were observed in HPV-positive patients.
