Abstract
Background and Objectives Gallbladder cancer is a relatively uncommon gastrointestinal malgnancy. Indications for adjuvant chemoradiation therapy after surgical resection have not yet been determined. We aimed this study to elucidate the effectiveness of adjuvant chemoradiation therapy according to TNM stage for gallbladder cancer. Methods Between March 2001 and March 2009, 100 patients with gallbladder cancer underwent surgical resection. We divided the patients according to TNM stage, and subdivided further according to whether adjuvant chemoradiation therapy was added or not. The clinicopathologic factors, recurrence and survival were retrospectively analyzed. Results Patients with gallbladder cancer at T2N0M0, T2N1M0, T3N0M0, and T3N1M0 stages were enrolled in this study. Among the four stages, the two lymph node‐negative stages (T2N0M0 and T3N0M0) did not show any gain in survival by adding adjuvant chemoradiation therapy. Conversely, the remaining lymph node‐positive stages (T2N1M0 and T3N1M0) showed gain in disease‐free survival, and the lymph node‐positive T2 stage (T2N1M0) showed gain in disease‐specific survival. In patients with lymph node‐positive T2/T3 GB cancers, adjuvant chemoradiation therapy was an independent prognostic factor for survival. Conclusions Adjuvant chemoradiation therapy is recommended for lymph node‐positive T2/T3 gallbladder cancer following surgical resection. J. Surg. Oncol. J. Surg. Oncol. 2010;102:87–93.Keywords
