RANDOMIZED TRIAL OF NEOADJUVANT CISPLATIN AND FLUOROURACIL VERSUS CARBOPLATIN AND FLUOROURACIL IN PATIENTS WITH STAGE IV-M0 HEAD AND NECK-CANCER

Purpose: A randomized trial was designed to compare cisplatin (CDDP) a nd fluorouracil (FU) versus carboplatin (CBDCA) and FU as neoadjuvant treatment in stage IV-MO head and neck cancer to assess whether CBDCA- FU is better than CDDP-FU with regard to response and toxicity, Patien ts cmd Methods: Patients were randomized to receive CDDP 100 mg/m(2) i ntravenously on day 1 and FU 5,000 mg/m(2) over a 120-hour continuous infusion, or CBDCA 400 mg/m(2) over a 24-hour continuous infusion on d ay 1 and FU with the same schedule, Both regimens were repeated every 21 days, The patients received three courses of chemotherapy, excludin g those who foiled to achieve a partial response (PR) after the second course, Complete responders were treated with radiotherapy, The remai ning patients underwent surgery if the tumor was resectable. Results: Interim analysis was performed when 95 patients were included, The tri al was stopped due to significantly better results in the control arm, Differences in response (P = .04) were favorable to CDDP-FU. Hematolo gic toxicity predominated in the CBDCA-FU arm (P < .001). Mucositis an d vomiting predominated in the CDDP-FU arm (P = .03, P < .001, respect ively), Favorable outcomes (complete response [CR] plus any grade of t oxicity and PR plus grade 0 to 3 toxicity) predominated in the CDDP-FU arm (P = .02). Only the treatment assigned was associated with respon se (P = .02) and favorable outcomes (P = .009) in the logistic regress ion analysis. In the CDDP-FU arm, disease-free and overall survival we re significantly better, Cox regression analysis showed that only trea tment association with disease-free survival remains significant, Conc lusion: Our results indicate that CDDP-FU is more effective than CBDCA -FU as neoadjuvant treatment in stage IV-MO head and neck cancer.
