Radical surgery for gallbladder cancer: a worthwhile operation?

Abstract

Aims: Extended operations are the only chance of a cure for patients with advanced gallbladder carcinoma, but there is no consensus about which subset of patients can benefit. The aim of this retrospective study is to evaluate the results of surgical resection with special reference to the prognostic factors and to long-term survival.

Methods: A retrospective review of 70 patients with a diagnosis of gallbladder cancer treated from 1985-1998 was performed: 33 patients had a curative resection and were included in this study. For stage I disease, simple cholecystectomy was considered curative; in most of the other cases, cholecystectomy was associated with lymph node dissection and liver resection.

Results: Hospital mortality and morbidity were 6% and 33%, respectively. Curative resection was associated with an actuarial 5-year survival of 27.4%. Survival of pT1-2 patients was significantly better than that of pT3 (P=0.04) or pT4 patients (P=0.002). Patients with lymph node spread had a poorer prognosis (P=0.06) but four were alive and disease-free with a median survival of 22 months.

Conclusions: Depth of the tumour and lymph node metastases are important prognostic factors. Patients with pT3-4 tumours or regional lymph node spread should be considered for curative resection because long-term survival is possible.
