Radical surgery for gallbladder cancer. Results of the French Surgical Association Survey

Gallbladder carcinoma is a highly lethal disease. The advantages of radical surgery remain controversial. The authors' objective was to evaluate the effectiveness of an aggressive approach to gallbladder carcinoma on long-term survival.

A questionnaire was sent to 73 institutions in France, Europe, and overseas. Data, from 724 patients treated between 1980 and 1989, were analyzed for patient sex and age, associated hepatobiliary diseases, symptoms and signs, diagnostic tests, operative management, pathology reports and survival. Seventy-eight percent of the patients were women, and 22% were men. Gallstones were present in 86% of the cases. Four percent of the patients had Tis lesions, 11% had T1 to T2 lesions, and 85% had T3 to T4 lesions.

Twenty-three percent of the patients underwent curative operations, and 77% had a palliative treatment (25% of the patients underwent exploratory laparotomy). Exploratory laparotomy was followed by the highest mortality rate (66%), and older patients (>70 years) had a higher operative risk. The overall median survival was 3 months, and long-term survival correlated with cancer stage: Tis >60 months, T1 to T2 >22 months, and T3 to T4 2 to 8 months. Projected five-year survival for cancers limited to the gallbladder and treated by simple cholecystectomy was 93%, 18% and 10% for Tis, T1 and T2 respectively. For T3 to T4, no difference was observed among the different surgical procedures adopted--hepatic resection, trans-tumoral stenting or biliary-enteric anastomosis.

In conclusion, a simple cholecystectomy is effective only for Tis cancer. An extended cholecystectomy for invasive cancer should be performed, but only if there is limited involvement of the immediately adjacent hepatic parenchyma. There is now a need to evaluate more effective adjuvant therapy in the form of radiotherapy or newer chemotherapeutic agents.
