AIMS AND BACKGROUND: [corrected] The purpose of the study was to analyze the long-term follow-up of a single institution's experience with a regimen of concomitant carboplatin + 5-fluorouracil (CBDCA + 5-FU) infusion and radiotherapy. STUDY DESIGN: Fifty-eight patients with locally advanced squamous cell head and neck cancer treated with combined chemoradiotherapy between March 1990 and October 1998 were reviewed retrospectively. According to the TNM tumor staging, 6 patients had stage II, 21 stage III and 31 stage IV tumors. The chemotherapy regimen consisted of the combination of 5-FU and CBDCA, for a total of 3 cycles. Both drugs were given as 4-day continuous intravenous infusions during the first and fourth week of radiation therapy: 5-FU at 1000 mg/m2 per day and CBDCA at 75 mg/m2 per day. Radiation was given in single daily fractions of 1.8 to 2 Gy, to a total dose of 66 to 70 Gy. RESULTS: After the completion of chemotherapy and radiotherapy, 34 patients (58.6%) achieved clinical and radiological (computerized tomography and/or magnetic resonance imaging) complete remission, 15 patients (25.9%) partial remission >50%, 5 patients (8.6%) partial remission <50%, and 4 patients (6.8%) had no response. Toxicity was intensive but tolerable. After a median follow-up of 25 months, overall survival and recurrence-free survival estimated for the whole patient population was 52% at 3 years, and the median length of recurrence-free survival was 23 months. CONCLUSIONS: Our regimen combining standard single daily fraction radiation with the conventional dose of CBDCA and 5-FU was given without dose modification regardless of the severity of the adverse effects. It gave a clinical complete response at the primary site in 58.6% of patients. With a 52% projected 3-year overall survival, our series compares favorably with similar studies in the literature. Therefore, our results with concomitant CBDCA/5-FU infusion and radiotherapy are encouraging and suggest that CBDCA can be substituted for cisplatin with a good therapeutic index.
