UFT (uracil and tegafur in a 4:1 molar ratio) plus calcium folinate treatment has favorable activity and tolerable toxicity in patients with advanced gastric carcinoma. High response rates have been reported in patients with advanced gastric carcinoma receiving a schedule of epirubicin, cisplatin (Platinol), and protracted infusion of 5-fluorouracil (5-FU). Replacing the inconvenient infusion pump and intravenous catheter needed for protracted infusion of 5-FU, we administered oral UFT plus calcium folinate (Orzel) to 37 patients (median age, 55 years; median World Health Organization [WHO] performance status of 1) with locally advanced or metastatic gastric carcinoma. Epirubicin 50 mg/m2 and cisplatin 60 mg/m2 were administered by intravenous injection on day 1; UFT 360 mg/m2/day po was administered in conjunction with oral calcium folinate 25 mg/m2/day in divided daily doses for 21 days, followed by a 7-day rest period. Courses were repeated every 4 weeks. Among 37 evaluable patients who received a median of four courses of treatment (range, 2 to 10), two achieved a complete response and 18 a partial response, for an overall response rate of 54% (95% confidence interval, 39% to 70%). Stable disease was reported in 12 patients (32.4%) and disease progression in another five (13.5%). The median duration of survival was 10 months (range, 2 to 15+). The main toxicities were nausea/vomiting, leukopenia, diarrhea, and oral mucositis. WHO grade 3 or 4 toxicity included leukopenia in 14 patients (37.8%), nausea/vomiting in 11 (29.7%), oral mucositis in five (13.5%), and diarrhea in four (10.8%). Epirubicin, cisplatin, and oral UFT plus calcium folinate, a convenient outpatient regimen, has significant activity and tolerable toxicities in patients with gastric carcinoma.
