Phase I trial of gemcitabine (Gemzar), 24 h infusion 5-fluorouracil and folinic acid in patients with inoperable pancreatic cancer.
Gemcitabine (Gemzar) has a significant impact upon survival and quality of life for patients with pancreatic cancer, compared with 5-fluorouracil (5-FU). This phase I study was initiated to define the recommended dose of 5-FU delivered as a 24 h infusion in combination with gemcitabine (1000 mg/m2) and folinic acid (200 mg/m2) in patients with inoperable pancreatic cancer, treated on an outpatient basis. Drugs were administered weekly for 4 weeks out of 6 weeks. Sixteen chemonaive patients (median age 59 years, range 51-66) were enrolled, 15 had stage IV and one stage III disease. The median Karnofsky performance score (KPS) was 70 (range 60-80). Six patients received 5-FU 750 mg/m2, eight received 5-FU 1000 mg/m2 and two received 5-FU 1250 mg/m2. The maximum tolerated dose of 5-FU was 1000 mg/m2. Hepatotoxicity was dose limiting. One patient who received 5-FU 1250 mg/m2 died as a result of hepatorenal failure. There was one partial response, nine patients had stable disease for more than 3 months and 13 patients had improved KPS. The median time to progressive disease was 31 weeks (range 5-50 weeks). A phase 11 trial is underway to further assess the activity of this combination at the recommended dose of 750 mg/m2 5-FU.
