Unique Identifier : AIDSLINE ICA10/94369795 AB OBJECTIVES: Patients (pts) receiving antineoplastic chemotherapy (CT) usually experience nausea (N) and vomiting (V) among its most distressing side effects. There are no data published in the literature regarding the evaluation of both granisetron and ondansetron in pts with HIV infection and under CT for malignant tumors. METHODS: From June to October 1993 we enrolled 16 consecutive pts (15 males and 1 female) with HIV infection and malignant tumors (14 non-Hodgkin's Lymphoma, 1 Kaposi's Sarcoma, 1 lung cancer) in a prospective randomized study comparing granisetron (3 mg/day) and ondansetron (8 mg prior to CT, 4 and 8 hours post CT): pts received one of the antiemetogenic drugs at the odd cycles and the alternative drug at the even cycles. RESULTS: The vast majority of these pts were intravenous drug abusers (13/16), but at the time of CT they were not reporting the use of illicit drugs. All pts were treated with moderately emetogenic CT regimens including cyclophosphamide, doxorubicin, vincristine, bleomycin, etoposide, cisplatin, mitoxantrone and prednimustine. The median age of our pts was 36 years (range 28-79 years) and the total number of administered cycles was 50 (25 with ondansetron and 25 with granisetron). During CT no significant difference between the two groups were observed: 5 episodes of N-V with ondansetron (4 G1 and 1 G2 according WHO) and 10 episodes of N-V with granisetron (6 G1, 3 G2 and 1 G4). The overall incidence and nature of adverse events was similar between the groups with headache and constipation occurring more frequently in both groups. DISCUSSION AND CONCLUSIONS: Our data show that both ondansetron and granisetron are highly effective agents for prophylaxis of emesis in patients with HIV infection and tumors receiving moderately emetogenic CT regimens. Granisetron may be preferred both for the single dose administration and the less expense, especially in pts with HIV infection with related socio-economic problems.
