Abstract | BACKGROUND: METHODS: 8031 patients with T4 or N2b to N3 disease undergoing RT and chemotherapy were divided into induction chemotherapy and concurrent chemotherapy cohorts. Multivariate analysis was used to explore the association of treatment with survival and to identify predictors of radiation dose. RESULTS: On multivariate analysis incorporating sociodemographic and clinical variables, survival of the induction chemotherapy cohort was not significantly different from that of the concurrent cohort (hazard ratio [HR], 0.96; 95% confidence interval [CI], 0.88-1.05; p = .35), nor on subgroup analyses of advanced disease. Multivariate analysis demonstrated increased odds of receiving <66 Gy among the patients in the induction chemotherapy cohort (p < .01). CONCLUSION:
Induction chemotherapy subjects experienced no survival advantage over concurrent chemotherapy subjects but were more likely to receive lower RT doses. © 2017 Wiley Periodicals, Inc. Head Neck 39: 1113-1121, 2017.
