Chemotherapy in the treatment of advanced gallbladder cancer

Abstract

Objective: To clarify the role of chemotherapy for advanced gallbladder cancer (GBC).

Methods: We reviewed 89 GBC patients: 21 admitted before 1997 were treated with a combination of cisplatin, epirubicin, and 5-fluorouracil (CEF); 25, admitted subsequently, received a combination of 5-fluorouracil, doxorubicin and mitomycin (FAM), and the remaining 43, ineligible for these trials, received supportive care. We investigated the relation between pretreatment clinical variables and long-term survival in these 89 subjects, and analyzed whether chemotherapy could favor longer survival.

Results: There were no significant differences in survival time between the chemotherapy groups, whereas the response rate to the CEF regimen was 4-fold higher than to the FAM regimen (32 vs. 8%). Subgroup analysis suggested that chemotherapy favored longer survival in patients with a performance status (PS) of 0 or 1, but not in patients with a PS of 2. Cox regression analysis suggested a significant hazard reduction by chemotherapy in patients with a PS of 0 or 1, but not in patients with a PS of 2.

Conclusions: GBC patients with poor PS should not be treated with chemotherapy at present. It is essential to design good clinical trials and develop more effective chemotherapy regimens.
