AbstractIn loco-regionally advanced head and neck squamous cell cancer (HNSCC), concurrent 3-weekly cisplatin improves overall survival (OS) compared to radiotherapy alone, but is often associated with renal toxicity. The use of radiotherapy with accelerated fractionation schedules has been reported to improve survival but its optimal combination with chemotherapy is unclear. Retrospective analysis of treatment outcome and nephrotoxicity of radiotherapy given with an intensity-modulated approach (IMRT) concurrent with either 3-weekly or weekly cisplatin in 94 patients with stage III/IV HNSCC. Patients treated with weekly cisplatin were significantly older (p=0.0014) and received a significantly lower total cisplatin dose (p=0.0002). With a median follow-up of 2.8 years, at univariate analysis, 3-weekly cisplatin shows a longer OS (p=0.041) but progression-free survival (PFS) is similar for both schedules (p=0.47). Cisplatin doses >240 mg/m(2) were associated with better OS but not PFS. Chronic renal failure rate was significantly higher with 3-weekly cisplatin (p=0.04). Multivariate analysis (Cox regression controlling for age) confirmed the significant and independent impact of alcohol and smoking habits on both PFS (HR, 2.2) and OS (HR, 2.3), while the treatment schedule affected only OS (HR, 2.2). Weekly cisplatin is less nephrotoxic. Both schedules can be combined to curative IMRT. PFS was not significantly different even if patients treated with the weekly schedule were significantly older and received reduced cisplatin doses. The study suggests that the different cisplatin dose doesn't affect the PFS results if concomitant to IMRT. Controlled prospective studies are needed.Copyright © 2011 Elsevier Ltd.
