Abstract
Forty patients receiving a total of 102 courses of cisplatin (CDDP)-based treatment were observed in the present study. The patients received an antiemetic prophylaxis with metoclopramide (6 mg/kg), dexamethasone (12 mg/m2), lorazepam (2.5 mg), promethazine (50 mg), and diazepam (10 mg). Complete protection from acute vomiting was obtained in 77.5% of patients during the first course, and partial protection (1 to 3 episodes of vomiting) was observed in 10.1% additional cases. Complete protection was achieved in 84.6% of males vs 57.1% of females. Patients at their first course of chemotherapy had 80% complete protection compared to 66.7% In those who received prior chemotherapy. No differences in the response rate between patients treated with high versus patients receiving low doses of CDDP were noted. The same pattern of response was observed in subsequent courses of therapy. Side effects were minimal (mild sedation in almost all the cases and hiccups in a few cases). No major extrapyramidal reaction was observed. The regimen used in the study showed good efficacy in preventing acute CDDP-induced nausea and vomiting. Moreover, the very low incidence of major side effects makes this protocol safe and recommendable in patients undergoing CDDP chemotherapy.
