Abstract

Purpose: No randomized trials have been conducted to directly compare radiotherapy (RT) with concomitant cisplatin (CDDP) versus concomitant cetuximab (CTX) as first-line treatment of locally advanced squamous cell carcinoma of the head and neck. In this randomized trial, we compared these two treatment regimens in terms of compliance, toxicity, and efficacy. Patients and Methods: Eligible patients were randomly assigned in a 1:1 ratio to receive either CDDP 40 mg/m2 once per week or CTX 400 mg/m2 as loading dose followed by CTX 250 mg/m2 once per week concomitant to radical RT. For primary end points, compliance to treatment was defined as number of days of treatment discontinuation and drug dosage reduction. The acute toxicity rate was defined according to the National Cancer Institute Common Toxicity Criteria. Efficacy end points were local recurrencefree survival, metastasis-free survival, cancer-specific survival, and overall survival. Results: The study was discontinued early because of slow accrual after the enrollment of 70 patients. RT discontinuation formore than 10 days occurred in 13%of patients given CTX and 0%given CDDP (P = .05). Drug dosage reduction occurred in 34% given CTX and 53% given CDDP (difference not significant). Toxicity profiles differed between the two arms, with hematologic, renal, and GI toxicities more frequent in the CDDP arm, and cutaneous toxicity and the need for nutritional support more frequent in the CTX arm. Serious adverse events related to treatment, including four versus one toxic deaths,were higher in the CTX arm(19%v 3%, P = .044). Locoregional control, patterns of failure, and survivals were similar between the treatment arms. Conclusion: CTX concomitant to RT lowered compliance and increased acute toxicity rates. Efficacy outcomes were similar in both arms. These results raise the issue of appropriately selecting patients with head and neck cancer who can benefit from CTX in combination with RT.
