Background:
Triweekly high-dose cisplatin (100 mg/m2 ) with concurrent radiation therapy is the current standard of care in the definitive or appropriate postoperative setting in head and neck squamous cell carcinoma (HNSCC). We compared triweekly 100 mg/m2 with alternative weekly 40 mg/m2 and weekly <40 mg/m2 cisplatin regimens.
Methods:
From 2011 to 2016, 163 patients received concurrent cisplatin and intensity-modulated radiotherapy for locally advanced HNSCC. Primary endpoints were overall survival (OS) and progression-free survival.
Results:
Cisplatin weekly <40 mg/m2 showed inferior OS outcomes when compared to weekly 40 mg/m2 (P = 0.084) and triweekly 100 mg/m2 (P = 0.04) regimens.
Conclusion:
Our study displayed inferior outcomes with weekly cisplatin doses under 40 mg/m2 , suggesting the inferiority of low-dose weekly chemotherapy and the need for ongoing randomized trials to further explore 40 vs 100 mg/m2 chemotherapy regimens.
