Evaluation of two modified ECF regimens in the treatment of advanced gallbladder cancer

Abstract

Gallbladder cancer is a rare disease and it is associated with a poor clinical outcome and survival. A standard therapy for it has not been established yet. The aim of this study is to evaluate efficacy and safety of two modified ECF regimens in advanced gallbladder cancer patients. Clinical data of 38 patients with advanced gallbladder cancer treated with modified ECF regimen were reviewed retrospectively. Of them, 21 patients received an epirubicin, cisplatin, and 5-FU/LV combination therapy. Seventeen patients received a chemotherapy of epirubicin, cisplatin, and capecitabine. Partial response was achieved in fourteen (36.84%) patients with a median duration of 5 months (range, 3-13 months), while stable disease was achieved in eight patients (21.05%). The median time to progression was 4.0 months (95% CI, 3.62-4.58 months). And the median overall survival was 9.8 months (95% CI, 7.26-12.34 months). Responders demonstrated better survival than non-responders (median survival time: 16 vs. 6.9 months, P = 0.008). The median survival time for epirubicin-, cisplatin- and capecitabine-treated patients was 9.2 versus 8.9 months for epirubicin-, cisplatin- and 5-FU/LV-treated patients. There was no statistical difference between both treatment groups in terms of survival time (P = 0.769). Regimen-related toxicity resulted in at least one treatment delay or dosage reduction in 63.2 and 34.2% patients, respectively. There were no chemotherapy-related deaths during the study. Modified ECF regimen with epirubicin, cisplatin and 5-FU/LV or substituting capecitabine for 5-FU/LV is still a potentially effective therapeutic chemotherapy for patients with advanced gallbladder cancer, and toxicity was manageable. There was no remarkable difference in efficacy between the two regimens.
