ABSTRACT
OBJECTIVES:
This study aimed to compare the efficacy of chemoradiotherapy (CRT) with radiotherapy (RT) alone for elderly patients (≥ 65 years) with stage IV inoperable head and neck cancer (IV-HNC).METHODS:
Elderly patients diagnosed with inoperable IV-HNC from 2010 to 2015 were identified using the SEER database. Then, we performed a 11 propensity-score matched (PSM) analysis to reduce treatment selection bias, and the prognostic role of CRT was investigated using Kaplan-Meier analysis, log-rank test, and Cox proportional hazard models. The main outcome was overall survival (OS), and the secondary outcome was cancer-specific survival (CSS).RESULTS:
A total of 3318 patients were enrolled, of whom 601 received RT alone and 2717 received CRT. Through PSM, 526 patients were successfully matched, and balances between the two treatment groups were reached. In the matched dataset, multivariable Cox analysis revealed that CRT was associated with better OS (HR = 0.580, P < 0.001) and CSS (HR = 0.586, P < 0.001). Meanwhile, subgroups of patients with IV-HNC (younger age, male sex, being married, black race, grade I-II, oral cavity site, T3-T4 stage, N0-N1 stage, M1 stage) were inclined to benefit more from CRT treatment. Furthermore, the survival benefit of CRT was more pronounced in patients aged 65 to 80 years, but was absent in patients aged 80 years or older.CONCLUSIONS:
This study indicated that CRT resulted in better survival than RT alone in elderly patients with inoperable IV-HNC, especially for those subpopulations that benefit more from CRT treatment.
