- W2267885473 abstract "6076 Background: Impressive outcomes have been achieved using multiagent neoadjuvant and concomitant chemotherapy combined with radiation in definitive treatment of head and neck cancer; these are associated with significant toxicities. The purpose of this study was to determine the efficacy and toxicities of single-agent weekly (CDDP) during curative-intent radiation therapy. Methods: 36 patients with AJCC Stage II (3%), Stage III (14%), Stage IV (83%) squamous cell carcinoma of the larynx, hypopharynx, oropharynx and oral cavity treated from 6/2000 to 11/2003 were retrospectively reviewed. Subjects received 72 Gy irradiation given either by hyperfractionation or IMRT technique with CDDP 30 mg/m 2 /wk throughout the radiation course. Cisplatin was held for Grade III/IV toxicities. The endpoints were best response, percentage of Grade III/IV toxicities, disease-free survival (DFS), overall survival (OS). Results: The median number of cycles of CDDP administered was 6. Grade III/IV toxicities: 11% of patients had anemia, 6% thrombocytopenia, 33% leukopenia, 0% renal failure, and 25% developed Grade III/IV mucositis; 1 patient (3%) died due to complications directly related to therapy. Responses to therapy included 72% CR, 17% PR, and 5% SD. Median follow-up for all patients was 19 months (34.5 months for living patients), DFS at 3 years (yrs.) was 59%, and OS at 3 yrs, was 40%. Nine patients died of disease up to 2.6 (median, 0.7) yrs. after treatment, while 11 died of intercurrent diseases up to 5.1 (median, 1.8) yrs. later. Fifteen are alive (2 with recurrence) at median 2.7 yrs. after treatment. Conclusion: Concomitant weekly CDDP with full-course radiation is feasible, tolerable, highly active, and comparable to more complex, costly and toxic regimens. Intercurrent disease was a significant contributor to mortality in our population. Our regimen is an attractive alternative to sequential chemoradiotherapy programs.
