    BACKGROUND: Nausea and vomiting are important symptoms observed in cancer patients. In a previous study we showed that delayed chemotherapyinduced nausea and vomiting (CINV) control could be potentially improved by skipping the administration of a 5HT3-antagonist on day 2. We report here a trial confirming our previous findings. PATIENTS/METHODS: A phase-IIIrandomized- placebo-controlled trial was conducted in which patients received (IV) ondansetron 16mg, dexamethasone 20mg and ranitidine 50mg before highly/moderately emetogenic chemotherapy (day 1).Starting on day 2, all patients received metoclopramide 10mg PO q8 hours (days 2,3 and 4, Dexamethasone 8mg QD (days 2 and 3) and Ranitidine 150mg q12 hours (days 2 and 3). Patients were randomized to receive either Granisetron 0.5mg PO (days 2 and 3) (Group A) or Placebo instead for Granisetron on day 2 and Granisetron 0.5mg on day 3 and 4 (Group B) RESULTS: 73 patients were enrolled. Groups were similar regarding clinical characteristics, despite better control during the acute phase of CINV in group A (p=0.04). Complete delayed protection from nausea/vomiting (DCPNV) from day 2 to 5 was similar in both groups. (30% vs. 32%; p=0.5). Analyzing DCPNV by logistic regression multivariate analyses, acute complete protection from nausea/vomiting (ACPNV) (p=0.001) and study group (p=0.06) were independently associated with DCPNV. Selecting patients who achieved ACPNV, we observed that group B had a superior DCPNV (85% vs 50%, p=0.02). CONCLUSION: DCPNV can be improved just by skipping day 2 of 5HT3- antagonists. Future studies should compare this inexpensive strategy with NK1- antagonists or second generation 5HT3-antagonists. Key words: delayed chemotherapy-induced nausea and vomiting, tachyphylaxis, cost- saving regimen, antiemetics, Granisetron/administration and dosage.
