RESUMO
Twenty-three patients with gynecological cancer who were treated with 85 cycles of cytotoxic chemotherapy containing platinum received intravenous granisetron repeatedly. Granisetron (3 mg/body) was drip-infused twice for each cycle at a 24-hour interval. The antiemetic efficacy was evaluated and compared for each day and each cycle, and analysed using the chi-square and H tests. There were no significant differences between the first cycle and the subsequent second through fifth cycles in the severity of nausea and the frequency of vomiting. The latter tended to increase in the second day of each cycle. These results indicated that granisetron does not decrease in antiemetic efficacy by repeated administration during multiple cycles of anti-cancer chemotherapy.
