title: Phase I study of gemcitabine in combination with cisplatin, 5-fluorouracil and folinic acid in patients with advanced esophageal cancer.
abstract: The prognosis for advanced esophageal carcinoma is poor with a median survival of 9-12 months and 5-year-survival rate of 10-20%. Combination chemotherapy with cisplatin and 5-fluorouracil (5-FU) is considered to be the standard therapy, but has a high potential of side effects and is usually not given on an ambulatory basis. This phase I study was designed to find the maximum tolerated dose (MTD) of weekly cisplatin in combination with standard doses of gemcitabine (1,000 mg/m(2), 30 min) and 5-FU (750 mg/m(2), 24 h)/folinic acid (200 mg/m(2), 30 min). All drugs were to be given on a day 1, 8, 15 and 22 of a 6-weekly cycle in an outpatient setting. Nineteen chemonaive patients with inoperable stage IIa, III and IV squamous cell carcinoma and adenocarcinoma of the esophagus were enrolled into the study. Eight, six and five patients were enrolled at cisplatin dose levels 0 (20 mg/m(2) ), I (25 mg/m(2) ) and II (30 mg/m(2)), respectively. One hundred and eighty-one out of 187 treatments (55 cycles) were given on an outpatient basis. The dose-limiting toxicities of this schedule were leukopenia and thrombocytopenia. Other side effects were mild. Dose level II (30 mg/m(2)) was defined as the MTD for cisplatin when used in this combination and schedule. Partial responses were observed in 10 of the 19 enrolled patients. The side effect profile seen in this study in combination with the preliminary evidence of efficacy justifies further testing in a phase II setting with a cisplatin dose of 25 mg/m(2) and offers a treatment option for patients in an outpatient setting.
