AbstractForty chemotherapy-naive patients receiving high-dose cisplatin were included in a pilot study of a combination of ondansetron plus metoclopramide as antiemetic therapy. Patients received ondansetron 16 mg plus metoclopramide 0.5 mg/kg in 250 cm3 of normal saline i.v. 15 min before cisplatin administration on day 1; then ondansetron 8 mg was given orally b.i.d. and metoclopramide 0.5 mg/kg was given intramuscularly t.i.d. for 4 days. This combination was given to all patients receiving the first cycle of chemotherapy. At the second cycle of chemotherapy all patients received the same antiemetic treatment as above plus methylprednisolone 125 mg i.v. on day 1 and the intramuscularly once a day for 4 days. There were 20 females and 20 males with a mean performance status of 1 (range 0-2) and a mean age of 58 years (range 36-68). Ten patients had ovarian carcinoma, eight patients had uterine adenocarcinoma and 22 and non-small cell lung carcinoma. The mean cisplatin dose was 96 mg/m2. All patients denied significant alcohol consumption. At cycle 1, complete protection against acute emesis was achieved in 22 patients (55%), major protection in 12 cases (30%), minor protection in four patients (10%) and failure in two cases (5%). On the other hand, the efficacy of this combination on delayed vomiting was not striking. For delayed vomiting, complete protection was observed in nine patients (23%), major protection in 13 cases (33%), minor protection in 10 patients (25%) and failure in eight cases (20%). At cycle 2, patients also received methylprednisolone showing complete protection from vomiting in 19 cases (47%) and major protection on 12 cases (30%). Results achieved with ondansetron plus metoclopramide are in the range reported for ondansetron alone in the medical literature. Although this study was not prospectively carried out in a randomized fashion, the results are not suggestive of a possible positive effect of metoclopramide addition to ondansetron. On the other hand, these results stress the role that corticosteroids may play in the control of delayed emesis. Toxicity was predictable and the frequency of side-effects was in the range reported in other studies with ondansetron.
