Phase II Trial of Gemcitabine, UFT-E, Leucovorin Combination Chemotherapy in Advanced Pancreatic Adenocarcinoma.
2002
Purpose: To evaluate the efficacy and toxicity of a Gemcitabine, UFT-E, Leucovorin combination chemotherapy in the treatment of advanced pancreatic adenocarcinoma Patients and Methods: Patients 70 years, with no prior chemotherapy and with bidimensionally measurable advanced pancreatic adenocarcinoma, ECOG performance status 2, and adequate bone marrow, kidney, and liver function were eligible for this trial. Eligibility criteria for clinical benefit assessment were pain with at least a daily analgesic consumption of two nonsteroidal anti-inflammatory drugs or a Karnofsky performance status between 50 and 70. Treatment consisted of 1,000mg/ of Gemcitabine on days 1, 8 and 15, repeated every 4 weeks, with UFT-E administered orally 500mg-700mg by body surface area (BSA). Leucovorin was administered 45mg/day orally. Dosages of UFT-E and Leucovorin were divided and administered three times per day from day 1 to day 21. After 7 days of rest, UFT-E and Leucovorin were administered repeatedly. Results: Twenty-three patients were enrolled between April 1999 to April 2000. Eighty two cycles (median, four cycles) were delivered to all patients. The objective response rate was 15.8% in 19 assessable patients and 13.0% in the intent-to-treat population. Twelve patients (57.9%) displayed stable disease. Grade 3 or 4 neutropenia occurred in 30.4% of patients, nausea/vomiting in 8.3%, diarrhea in 4.3%, and mucositis in 4.3%. The median time to progression was 8 months. The median survival was 8 months in the assessable population and 6 months in the intent-to-treat population Clinical benefit was achieved in 11 (57.9%) of 19 assessable patients. Conclusion: Gemcitabine, UFT-E, Leucovorin combination chemotherapy is a well-tolerated and safe regimen in cases of advanced pancreatic adenocarcinoma. Although the response rate is low, it shows a survival benefit and clinical benefit and deserves further evaluation in a phase III trial.
