Patients' self-reported functional status after granisetron or ondansetron therapy to prevent chemotherapy-induced nausea and vomiting at six cancer centers

Patient functional status after administration of either granisetron or ondansetron to prevent acute chemotherapy-induced nausea and vomiting (CINV) was studied. Pharmacists and nurses from six cancer centers distributed Functional Living Index-Emesis (FLIE) questionnaires to 115 outpatients receiving either granisetron or ondansetron for prevention of CINV. The emetogenic potential of each patient's chemotherapy regimen was high, moderately high, or moderate. Immediately before and 72 hours after chemotherapy, each patient rated his or her reaction to each of 18 items on the questionnaire on a 7-point scale. Possible scores ranged from 18 to 126, with higher scores indicating higher levels of functioning. The occurrence of nausea in the granisetron group was 40.0% compared with 43.2% in the ondansetron group; the occurrence of vomiting was 18.8% in the granisetron group and 11.1% in the ondansetron group. Patients who received highly emetogenic chemotherapy had significantly lower scores on the FLIE after chemotherapy than before. Patients with both nausea and vomiting reported a much higher negative impact on functional status after chemotherapy than those with nausea only. The mean prechemotherapy and postchemotherapy FLIE scores were 124.2 and 110.4 for granisetron and 124.9 and 111.9 for ondansetron. Granisetron and ondansetron did not differ significantly in their effect on functional status reported by patients before and 72 hours after receiving cancer chemotherapy.
