Prognostic Significance of the Number of Positive Lymph Nodes in Gallbladder Cancer

The aim of this study was to assess the prognostic impact of the number of lymph node metastases. The medical records of 33 patients with node-positive gallbladder cancer (GBC) treated at our institution from January 1985 through December 2002 were reviewed. There were 10 cases with a single node me...

Description
Summary:The aim of this study was to assess the prognostic impact of the number of lymph node metastases. The medical records of 33 patients with node-positive gallbladder cancer (GBC) treated at our institution from January 1985 through December 2002 were reviewed. There were 10 cases with a single node metastasis. The sites were as follows: the cystic duct node, the pericholedochal node, the retroportal node, the hilar node, the lymph node around the common hepatic artery, and the paraaortic node. According to the International Union Against Cancer (UICC) 5th edition, 5-year survival rates for the patients with pN1, pN2, and greater than pN2 were 19.2%, 10%, and 0%, respectively (not significant). Patients with a single node metastasis had a higher 5-year survival rate (33%) than patients with two or more lymph node metastases (0%; P < 0.05). There were no lymph node recurrences in patients with a single node metastasis. Number of positive nodes and liver metastasis were factors predictive of significantly worse survival. Rather than using the topographic classification, or even simply classifying whether nodal involvement is positive or negative, classification according to the number of positive nodes will contribute to establishing a more practically useful staging system.
