P. Cubertafond et al., Radical surgery for gallbladder cancer. Results of the French Surgical Association survey, HEP-GASTRO, 46(27), 1999, pp. 1567-1571
BACKGROUND/AIMS: Gallbladder carcinoma is a highly lethal disease. The adva
ntages of radical surgery remain controversial. The authors' objective was
to evaluate the effectiveness of an aggressive approach to gallbladder carc
inoma on long-term survival.
METHODOLOGY: 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, sympto
ms and signs, diagnostic tests, operative management, pathology reports and
survival. Seventy-eight percent of the patients were women, and 22% were m
en. Gallstones were present in 86% of the cases. Four percent of the patien
ts had Tis lesions, 11% had T1 to T2 lesions, and 85% had T3 to T4 lesions.
RESULTS: Twenty-three percent of the patients underwent curative operations
, and 77% had a palliative treatment (25% of the patients underwent explora
tory laparotomy). Exploratory laparotomy was followed by the highest mortal
ity rate (66%), and older patients (>70 years) had a higher operative risk.
The overall median survival was 3 months, and long-term survival correlate
d 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 gallblad
der 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 dif
ferent surgical procedures adopted - hepatic resection, trans-tumoral stent
ing or biliary-enteric anastomosis.
CONCLUSIONS: In conclusion, a simple cholecystectomy is effective only for
Tis cancer. An extended cholecystectomy for invasive cancer should be perfo
rmed, 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.
