Title: Concurrent chemoradiotherapy with cisplatin or cetuximab for locally advanced head and neck squamous cell carcinomas: Does human papilloma virus play a role? Author: Ou D, Levy A, Blanchard P, Nguyen F, Garberis I, Casiraghi O, Scoazec JY, Janot F, Temam S, Deutsch E, Tao Y. Journal: Oral Oncol; 2016 Aug; 59():50-57. PubMed ID: 27424182. Abstract: OBJECTIVES: The optimal concurrent regimen, chemoradiotherapy (CRT) or bioradiotherapy (BRT), in locally advanced head and neck squamous cell carcinoma (LAHNSCC) remains controversial, especially in human papilloma virus-associated patients. MATERIAL AND METHODS: Data of 265 patients with LAHNSCC treated with CRT (cisplatin, 100mg/m(2) every 3weeks, n=194) or BRT (weekly cetuximab, n=71), including 119 patients with known HPV/p16 status were analyzed. RESULTS: Median follow-up was 54.5months. The 5-year progression-free survival (PFS) and locoregional control (LRC) were 51.7% vs. 36.9% (p=0.01) and 74.2% vs. 51.2% (p=0.002), both in favor of CRT. Multivariate analysis adjusted for p16 status continued to show improved outcomes (PFS and LRC) for CRT. The 5-year LRC was significantly better with CRT vs. BRT both in the p16+ subgroup (p=0.01) and in p16- or unknown subgroup (p=0.02), and 5-year PFS was of non-significant trend of improvement with CRT vs. BRT in both subgroups (p=0.07 in p16+ and p=0.09 in p16- or unknown, respectively). In the subset of oropharyngeal cancer patients with HPV/p16 status available (n=88), MVA after adjusted for other clinical co-variates showed a non-significant trend of improvement of LRC with CRT compared with BRT (HR=0.4, 95%CI, 0.1-1.0; p=0.06). CONCLUSION: Our long-term results suggested better outcomes in LAHNSCC patients receiving concurrent cisplatin over cetuximab regardless of HPV/p16 status.[Abstract] [Full Text] [Related] [New Search]
