Chemotherapy with gemcitabine plus cisplatin in patients with advanced biliary tract carcinoma at Chang Gung Memorial Hospital: a retrospective analysis.

Background: A gemcitabine-cisplatin combination is a standard treatment option for patients with advanced biliary tract carcinoma (BTC). We assessed the efficacy and safety of this regimen at Chang Gung Memorial Hospital.

Methods: Between April 2009 and December 2010, 30 chemotherapy-naïve patients (13 men and 17 women; median age: 61.5 years) with advanced BTC were retrospectively analyzed. Treatment consisted of gemcitabine (Gemmis(®); TTY, Taipei, Taiwan) 1000 mg/m(2), followed by cisplatin 30 mg/m(2) on days 1 and 8 every 3 weeks. Tumor response was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) criteria every 2-3 cycles. The toxicity was assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events, Version 3.

Results: At the end of July, 2011, 27 patients were evaluated using the RECIST criteria. According to the intent to treat analysis of response, 5 patients (16.7%) had a partial response, 10 patients (33.3%) had stable disease and 12 patients (40.0%) had progressive disease. The median time to progression (TTP) and median overall survival (OS) of the 30 patients were 4.8 months and 13.4 months, respectively. The patients with biliary obstruction requiring drainage before treatment had a significantly shorter OS than those without biliary obstruction (p = 0.02) even though the TTP showed no statistically significant difference (p = 0.69) between groups. The major grade III/IV adverse events in the 30 patients included infection (n = 8, 26.7%), anemia (n = 5, 16.7%), neutropenia (n = 4, 13.3%), and elevated alanine aminotransferase (n = 2, 6.7%). There were no treatment-related deaths.

Conclusions: Gemcitabine plus cisplatin is a feasible chemotherapy regimen with manageable toxicity in patients with advanced BTC. Maintaining good biliary drainage is essential for these patients.
