Background: To ensure safe delivery of oncologic care during the COVID-19 pandemic, telemedicine has been rapidly adopted. However, little data exist on the impact of telemedicine on quality and accessibility of oncologic care. This study assessed whether conducting an office visit for thoracic oncology patients via telemedicine affected time to treatment initiation and accessibility.Methods: This was a retrospective cohort study of patients with thoracic malignancies seen by a multidisciplinary team during the first surge of COVID-19 cases in Philadelphia (March 1 to June 30, 2020). Patients with an index visit for a new phase of care, defined as a new diagnosis, local recurrence, or newly discovered metastatic disease, were included.Results: 240 distinct patients with thoracic malignancies were seen: 132 patients (55.0%) were seen initially in-person vs 108 (45.0%) via telemedicine. The majority of visits were for a diagnosis of a new thoracic cancer (87.5%). Among newly diagnosed patients referred to the thoracic oncology team, the median time from referral to initial visit was significantly shorter amongst the patients seen via telemedicine vs. in-person (median 5.0 vs. 6.5 days, p < 0.001). Patients received surgery (32.5%), radiation (24.2%), or systemic therapy (30.4%). Time from initial visit to treatment initiation by modality did not differ by telemedicine vs in-person: surgery (22 vs 16 days, p = 0.47), radiation (27.5 vs 27.5 days, p = 0.86, systemic therapy (15 vs 13 days, p = 0.45).Conclusions: Rapid adoption of telemedicine allowed timely delivery of oncologic care during the initial surge of the COVID19 pandemic by a thoracic oncology multi-disciplinary clinic.

Purpose: Acute hospital encounters in patients undergoing curative-intent radiation therapy (RT) have not previously been well characterized. Understanding acute visit patterns among RT patients yields insights for risk assessments and cancer urgent care clinics that could decrease hospitalization rates and reduce health care costs. This study aims to identify patient, disease-site, and treatment characteristics associated with emergency department visits and inpatient admissions in cancer patients treated with definitive RT.Methods and Materials: A retrospective cohort study was conducted using data from a quaternary-care cancer center. The cohort was defined as all consecutive patients aged ≥ 18 years who began RT between July 1, 2011, and December 31, 2013; were without metastases; and were treated with curative intent. An acute encounter was defined as an emergency department visit or inpatient admission during RT or within 30 days after the conclusion of RT.Results: Among 1852 unique RT courses, 666 RT courses (36.0%) involved at least 1 acute encounter, and a total of 1418 acute encounters were identified. RT courses with at least 1 acute encounter corresponded to patients more likely to be on their second (odds ratio [OR], 1.96; P < .001) or third (OR, 3.82; P < .05) RT course and undergoing concurrent chemotherapy (OR, 6.38; P < .001). Among the RT courses with at least 1 acute encounter, the most common disease site was thoracic (22.8%), followed by head and/or neck (22.2%) and gastrointestinal (18.3%). Central nervous system tumors had the greatest proportion of RT courses with acute encounters (77.1%).Conclusions: In this retrospective analysis, more than one-third of curative-intent RT courses were associated with at least 1 acute hospital encounter during or shortly after irradiation. Given that acute encounters varied by patient, disease-site, and treatment characteristics, these findings can inform targeted preventive measures to reduce cancer-related acute hospital encounters and guide improved management protocols.

Objectives Efficient use of nivolumab in non-small-cell lung cancer (NSCLC) has been limited by the lack of a definitive predictive biomarker. In patients with metastatic melanoma treated with ipilimumab, a pretreatment neutrophil-to-lymphocyte ratio (NLR) < 5 has been associated with improved survival. This retrospective cohort study aimed to determine whether the pretreatment NLR was associated with outcomes in NSCLC patients treated with nivolumab. Methods We reviewed the medical records of all patients with previously treated advanced NSCLC who received nivolumab between March 2015 and March 2016 outside of a clinical trial at the University of Pennsylvania. Patients were dichotomized according to pretreatment NLR < 5 vs. ≥5. Multivariable logistic regression and Cox proportional hazards models were used to assess the impact of pretreatment NLR on overall survival (OS), progression-free survival (PFS), and overall response rate (ORR). Results 175 patients were treated. Median age was 68 (range, 33–88); 54% were female. Twenty-five percent of patients had an Eastern Cooperative Oncology Group Performance Status (ECOG PS) ≥2; 46% had received ≥2 prior systemic therapies. In multivariate analyses, pretreatment neutrophil-to-lymphocyte ratio (NLR) ≥5 was independently associated with inferior OS (median 5.5 vs. 8.4 months; HR 2.07, 95% CI 1.3–3.3; p = 0.002) and inferior PFS (median 1.9 vs. 2.8 months; HR 1.43, 95% CI 1.02–2.0; p = 0.04). Conclusions In a cohort of patients with NSCLC treated with nivolumab in routine practice, pretreatment NLR ≥ 5 was associated with inferior outcomes. It is unclear whether this marker is predictive or prognostic. Prospective studies are warranted to determine the utility of NLR in the context of other biomarkers of programmed death-1 (PD-1) therapy. [ABSTRACT FROM AUTHOR]
