BACKGROUND: Patients with carcinoma of the gallbladder have advanced, unresectable tumor at the time of presentation and face a dismal prognosis in the absence of a standard palliative chemotherapy regimen. This study was undertaken to evaluate the efficacy and safety of combined chemotherapy of gemcitabine and carboplatin in 20 patients with advanced gallbladder carcinoma. METHODS: The criteria of eligibility included chemonaive patients with unresectable gallbladder cancer, bidimensionaIly measurable disease, Zubrod's performance status≤2, and adequate major organ function. The patients received gemcitabine (1000 mg/m^2) on days 1 and 8, and carboplatin (target AUC of 5.0 mg/ml) on day 1, in a 21-day cycle. CT was used for response assessment. RESULTS: In this group of 20 patients with advanced gallbladder carcinoma 6 were men and 14 women, with a median age of 55 years. The stage of the tumor at presentation was IVB in 14 patients (70%), IVA in 3 (15%) and Ⅲ in 3 (15%). Four patients (21%) achieved a complete response, and 3 (15.7%), a partial response; an overall response rate was 36.7%. The median time to progression of the tumor was 33.8 weeks, and 1-year survival rate of the patients was 43.3%. Anemia of WHO grade Ⅲ or Ⅳ was seen in 2 patients (10%) and 1 patient (5%), respectively. Grade Ⅲ neutropenia and thrombocytopenia were observed in 2 patients (10%) and 1 patient (5%), respectively. CONCLUSION: With mild toxicity, combined chemotherapy of gemcitabine and carhoplatin is effective in the treatment of advanced gallbladder carcinoma.
