Objective: To comprehensively examine the prognostic significance of extranodal extension (ENE) in human papillomavirus-positive oropharyngeal squamous cell carcinoma (HPV-positive OPSCC)., Methods: Retrospective cohort of cases diagnosed with HPV-positive OPSCC from 2010 to 2015 in the National Cancer Database. Inclusion of all OPSCC HPV-positive cases with appropriate International Classification of Diseases-0-3 codes that received surgery with a neck dissection. Univariate and multivariable analyses were conducted. Hazard ratios (HR) for the independent effects of ENE and N stage on overall survival were estimated by Cox proportional hazards regression., Results: Cases that were ENE-negative had the highest 5-year survival (92.6%; 95% confidence interval [CI]: 90.5%-94.7%). ENE-positive cases had the lowest 5-year survival (84.0%; 95% CI: 80.7%-87.4%). After adjusting for confounding variables, ENE-positivity was associated with almost twice the hazard of death (HR = 1.90; 95% CI: 1.35-2.67) compared to ENE-negative cases. Nodal (N) category 1, ENE-positive status was associated with an increased risk of death (HR = 1.88; 95% CI: 1.26-2.80) compared with N1, ENE-negative status. Compared to N1/ENE-negative cases, N2/ENE-positive cases had the poorest survival (HR: 2.93; 95% CI: 1.94-4.43). Both microscopic and macroscopic ENE were associated with worse outcomes compared to node-positive/ENE-negative status., Conclusion: The implementation of the American Joint Committee on Cancer 8th edition staging system provides a much-improved framework to develop and discuss treatment plans for HPV-positive OPSCC. We feel that careful consideration should be given to the importance of ENE in patients with HPV-positive OPSCC., Level of Evidence: 4 Laryngoscope, 130:939-945, 2020., (© 2019 The American Laryngological, Rhinological and Otological Society, Inc.)

Background: To determine practice patterns and outcomes of laryngeal small cell cancer (LSCC) across the United States., Methods: Patients with LSCC were identified in the National Cancer Database. Overall survival (OS) was compared with Kaplan-Meier analysis and Cox regression., Results: From 2004 to 2014, the 5-year OS for early stage (n = 47), locally advanced stage (n = 133), and metastatic disease (n = 53) was 34%, 26%, and 9%, respectively. Chemoradiation was given in 66% of cases. Chemotherapy was less likely given in early stage disease (P = .001), and definitive radiation was less likely given in metastatic disease (P < .001). Definitive radiation improved median OS in locally advanced LSCC (20 vs. 7 months, log-rank P = .04). In multivariable modeling, radiation dose ≥40 Gy was associated with better OS (P < .001)., Conclusion: Chemoradiation was the most common practice for treating locally advanced LSCC, and radiation dose ≥40 Gy was associated with improved OS., (© 2018 Wiley Periodicals, Inc.)

Purpose: Elderly patients with muscle invasive bladder cancer can pose a therapeutic dilemma, given multiple comorbidities which may preclude surgery. In this registry based analysis we investigated treatment patterns and survival outcomes in this group of patients., Materials and Methods: We queried the National Cancer Database for muscle invasive (cT2-T4aN0M0) bladder cancer in patients 80 years old or older who were diagnosed from 2004 to 2013. Patients included in study underwent transurethral resection of bladder tumor followed by radical cystectomy, radical cystectomy plus chemotherapy, radiation therapy alone, chemotherapy alone, chemoradiation or no treatment. We performed Kaplan-Meier, log rank and multivariate Cox proportional hazards regression and propensity score matching., Results: A total of 9,270 patients were identified with a median followup of 12.8 months. Median overall survival in patients treated with radical cystectomy alone was 23.2 months (95% CI 19.8-26.6), which was superior to that of chemotherapy alone or radiation therapy alone (p <0.0001). Those treated with chemoradiation had a median overall survival of 27.3 months (95% CI 25.0-29.7), which did not statistically differ from that of radical cystectomy alone (p = 0.39). Surgery plus chemotherapy showed the longest median overall survival of 34.5 months (95% CI 22.2-46.7, vs chemoradiation and radical cystectomy alone p <0.0001). On multivariate analysis and propensity score matching the best overall survival was seen in patients treated with surgery plus chemotherapy and there was no difference in overall survival between chemoradiation and radical cystectomy alone., Conclusions: In elderly patients with muscle invasive bladder cancer chemoradiation is an alternative definitive treatment strategy with survival equal to that of surgery alone and superior to that of chemotherapy alone or radiation therapy alone. If a patient was able to receive neoadjuvant or adjuvant chemotherapy with surgery, additional survival was observed in this nonrandomized study., (Copyright © 2018 American Urological Association Education and Research, Inc.
