Abstract: OBJECTIVES/HYPOTHESIS: To examine associations between treatment and volume with survival and costs in elderly patients with laryngeal squamous cell cancer (SCCA). STUDY DESIGN: Retrospective cross-sectional analysis of Surveillance, Epidemiology, and End Results-Medicare data. METHODS: We evaluated 2,370 patients diagnosed with laryngeal SCCA from 2004 to 2007 using cross-tabulations, multivariate logistic and generalized linear regression modeling, and survival analysis. RESULTS: Chemoradiation was significantly associated with supraglottic tumors (relative risk ratio: 2.6, 95% confidence interval [CI]: 1.7-4.0), additional cancer-directed treatment (odds ratio [OR]: 1.8, 95% CI: 1.2-2.7), and a reduced likelihood of surgical salvage (OR: 0.3, 95% CI: 0.2-0.6). Surgery with postoperative radiation was associated with significantly improved survival (hazard ratio [HR]: 0.7, 95% CI: 0.6-0.9), after controlling for patient and tumor variables including salvage. High-volume care was not associated with survival for nonoperative treatment but was associated with improved survival (HR: 0.7, 95% CI: 0.5-0.8) among surgical patients. Initial treatment and 5-year overall costs for chemoradiation were higher than for all other treatment categories. High-volume care was associated with significantly lower costs of care for surgical patients but was not associated with differences in costs of care for nonoperative treatment. CONCLUSIONS: Chemoradiation in elderly patients with laryngeal cancer was associated with increased costs, additional cancer-directed treatment, and a reduced likelihood of surgical salvage. Surgery with postoperative radiation was associated with improved survival in this cohort, and high-volume hospital surgical care was associated with improved survival and lower costs. These findings have implications for improving the quality of laryngeal cancer treatment at a time of both rapid growth in the elderly population and diminishing healthcare resources.
