Introduction : This study evaluated discriminatory value of newly proposed AJCC 8th staging system compared to the AJCC 7th staging system for distal bile duct cancer
Methods : We retrospectively reviewed database of 223 patients who underwent surgery for distal bile duct cancer at a single institute from January 2002 through december 2012. Clinicopathologic characteristics and survival rates were analyzed based on 7th and 8th edition of AJCC staging system, respectively.
Results : Among pathologically-stage patients, P values for pairwise comparisons among different 8th AJCC stage were significant(P< 0.05) for stage IIa vs IIb only(P=0.012). C-index for adenocarcinoma was: 0.717 according to the 7th edition of AJCC and 0.720 according to the clinical 8th edition of AJCC.
Conclusions : There was no prognostic improvement following new 8th edition of AJCC compared to 7th edition of AJCC.
