title: Phase II study of gemcitabine and cisplatin in advanced biliary tract cancer.
abstract: BACKGROUND
  The aim of this phase II study was to determine the efficacy of gemcitabine plus cisplatin chemotherapy in patients with advanced biliary tract cancer.
  
  
  METHODS
  Eligibility criteria included histologically confirmed adenocarcinoma with measurable tumor in the biliary tract that was unresectable and either locally advanced or metastatic. Patients received a combination of gemcitabine (1000 mg/m(2) intravenously [IV] on days 1, 8, and 15) and cisplatin (75 mg/m(2) IV on day 1). Cycles were repeated every 28 days. Objective tumor response rates and toxicities were evaluated according to World Health Organization criteria.
  
  
  RESULTS
  Twenty-seven patients were enrolled in the study and a total of 120 cycles of chemotherapy were administrated. Objective partial response was observed in nine (33.3%) patients, while stable disease was found in seven (25.9%) patients. The median survival time was 10.0 months and the 1-year survival rate was 36%. Median time to disease progression was 5.6 months. The most common grade 3-4 toxicities were leukopenia (25.9%), anemia (29.6%), thrombocytopenia (22.2%), and vomiting (18.5%). Only one patient was hospitalized for chemotherapy-related complications.
  
  
  CONCLUSIONS
  Gemcitabine and cisplatin combination chemotherapy is an effective, safe, and well-tolerated regimen for the treatment of advanced biliary tract cancer.
