Title: Concurrent Cisplatin and Radiation Versus Cetuximab and Radiation for Locally Advanced Head-and-Neck Cancer

Purpose: To compare concurrent cisplatin (CDDP) and radiation (RT) with cetuximab (C225) and RT for locally advanced head-and-neck cancer (LAHNC). Methods and Materials: This study retrospectively compared 174 consecutive, newly diagnosed LAHNC patients definitively treated from March 1, 2006, to April 1, 2008, with single-agent CDDP/RT (n = 125) or C225/RT (n = 49). We excluded patients who received additional concurrent, induction, or adjuvant systemic therapy; weekly cisplatin; prior head-and-neck radiotherapy; or primary surgical resection. Outcomes were analyzed by the Kaplan-Meier method, Cox model, and competing-risks analysis tools. Results: The C225/RT patients were older and had decreased creatinine clearance. At a median follow-up of 22.5 months for living patients, the 2-year locoregional failure rate was 5.7% for CDDP/RT and 39.9% for C225/RT (p < 0.0001). The 2-year failure-free survival (FFS) and overall survival (OS) rates were 87.4% vs. 44.5% (p < 0.0001) and 92.8% vs. 66.6% (p = 0.0003), respectively, in favor of CDDP/RT. When the Cox proportional hazards model was used for multivariate analysis, treatment with CDDP/RT predicted for improved locoregional control (p < 0.0001), FFS (p < 0.0001), and OS (p = 0.01). Late Grade 3 or 4 toxicity or feeding tube dependence 9 months after completion ofmore » RT was observed in 21% of patients in the CDDP/RT cohort and 24% in the C225/RT cohort (p = 0.66). Conclusions: In this study of LAHNC patients, CDDP/RT achieved better locoregional control, FFS, and OS than C225/RT. Although the results were upheld on multivariate analysis, they must be interpreted cautiously because of the retrospective nature of the study and significant differences in patient selection. There was no statistically significant difference in late Grade 3 or 4 effects or feeding tube dependence.« less
