Abstract
340 Background: Gallbladder cancer (GBC) is one of the most common malignancies of the biliary tract. Because of the lack of specific presentations, this condition is frequently diagnosed only at an advanced stage. Obstructive jaundice is generally regarded as an indicator of far advanced disease, unresectability, and poor prognosis. The aim of this study was to evaluate clinicopathological factors, especially jaundice, influencing outcome after radical resection of gallbladder cancer, in order to identify the patients benefiting from radical surgery. Methods: Seventy-five patients with GBC underwent surgical resection between 1998 and 2008. A retrospective analysis was conducted on sixty-four patients with UICC T2 or more tumors. Clinicopathologic features, extents of resection, and survival rates were investigated retrospectively. Obstructive jaundice was defined that serum T-bil level was more than 2.0 mg/ml. Patients with jaundice underwent ENBD or PTBD and curative resection was performed when serum T-Bil level decreased below 2.0 mg/ml. Right after laparotomy, para-aortic lymphadenectomy and frozen section pathology were performed to convert a radical resection to a palliative procedure when a para-aortic lymph node was positive. Results: The three and five-year disease-specific survival rates were 47% and 41%, respectively. Nine patients survived for more than five years.Univariate analysis showed that blood loss during operation, hepatic invasion, portal vein invasion, N category, M category after postoperative pathological examination and residual tumor were significant prognostic factors (p<0.05), but multivariate analysis showed that M category only was independent prognostic factor (p<0.05). Five-year disease-specific survival rates for patients with (n=37) and without (n=27) obstructive jaundice were 47% and 35%, respectively (p=0.69). Conclusions: Obstructive jaundice had no impact on postoperative survival as long as metastatic disease was exclueded and adequate resection of the hepatic hilum was performed. Aggressive surgery might bring long-term survival in selected patients even with obstructive jaundice by advanced gallbladder cancer. No significant financial relationships to disclose.
