BACKGROUND: The antiemetic effects of serotonin receptor antagonists during chemoradiotherapy for solid tumors have never been reported. We have developed hyperthermo-chemo-radiotherapy (HCR) for esophageal cancer. However, with this treatment, the more potent the chemotherapy was, the more frequently emesis was experienced. MATERIALS AND METHODS: Fifteen patients with esophageal cancer underwent HCR (6 courses of hyperthermia, cisplatin 20 mg/m2 x 6, 5-FU 300 mg/m2 x 15 and radiation 1.5 Gy x 30). Ramosetron was administered intravenously (0.3 mg x 15). The emesis inhibition rate was defined as the rate of patients having neither vomiting nor severe nausea. RESULTS: The incidence of patients without nausea gradually decreased to 60% at the end of chemotherapy. However, vomiting was completely avoided except in one patient for two days. The emesis inhibition rates of weeks 1, 2, 3 and 4 were 100.0, 93.3, 89.5 and 95.2%, respectively. The overall inhibition rate was 94.5% and the rate of "well inhibited" was 79.0%. There were no ramosetron-related adverse reactions. CONCLUSIONS: These findings suggest that ramosetron is a useful antiemetic agent for nausea and vomiting induced by chemoradiotherapy for solid tumors.
