ABSTRACT
BACKGROUND:
The aim of the study was to test the clinical efficacy and toxicity profile of gemcitabine (GEM) in combination with cisplatin (CDDP) in a series of patients affected by unresectable and/or metastatic biliary tree carcinoma (BTC) previously untreated with chemotherapy. PATIENTS ANDMETHODS:
Overall 38 consecutive patients who satisfied eligibility criteria (10 with gall-bladder carcinoma and 28 with bile duct carcinoma) were included in this phase II study. Median age was 61 years with median PS 1. Treatment included GEM 1000 mg/m(2)/week as 30 min i.v. on days 1 and 8, and CDDP 75-80 mg/m(2) on day 1 with adequate hydration protocol and forced diuresis. Treatment was repeated every 3 weeks for three cycles before first re-evaluation of disease status.RESULTS:
According to an intent-to-treat analysis a complete response (CR) was achieved in 1 patient (3%) with duration of 8 months. A partial response (PR) was recorded in 11 cases (29%; 95% CI 6% to 48%) with a median duration of 6.4 months (range 5-11 months) for an overall response rate (ORR) of 32%. Stable disease (SD) was seen in eight cases (21%), while the remaining 18 patients showed progressive disease (PD). Tumor growth control rate was 53%. Objective responses were recorded at loco-regional disease, liver and nodal metastases. Lung and peritoneal metastases did not respond. Time-to-progression was 4 months (range 2-11 months) and median overall survival was 8+ months (range 2-15 months). Side-effects were mild with few cases of grade 4 hematological toxicity. Transient and reversible liver toxicity was recorded in nearly one-quarter of patients. Infection without severe grade 4 neutropenia was observed in three cases. In no case was chemotherapy withdrawn for toxicity.CONCLUSION:
The GEM/CDDP regimen is active against advanced and/or metastatic BTC with a favourable toxicity profile. This regimen represents a reasonable therapeutic choice for palliation of advanced BTC. Inferences concerning overall survival are difficult to draw due to the phase II nature of the study.
