Radiotherapy-induced emesis is poorly controlled with existing antiemetics. 5-Hydroxytryptamine (5HT3) receptor antagonists are a new class of antiemetics which have been demonstrated to be effective in controlling cytotoxic-induced emesis. We have prospectively studied the antiemetic efficacy of the 5HT3 receptor antagonist granisetron in an open non-randomized efficacy and toxicity study, at two dose levels, in patients receiving lower hemibody radiotherapy for multiple bone metastases. Of the 22 patients studied, 13 patients received 20 micrograms/kg and nine patients 40 micrograms/kg of granisetron, administered as an intravenous infusion 1 h before radiotherapy. Radiotherapy was administered as a single exposure to the lower half body to a midline dose of 8 Gy. A complete response (no nausea or vomiting) was observed in 9/13 patients at the lower dose level and 6/9 patients at the higher level. No major adverse events were recorded. We conclude that granisetron is a well-tolerated and effective antiemetic agent in radiotherapy-induced emesis. Formal comparison with conventional antiemetic agents in this situation is required.
