Abstract

BACKGROUND/PURPOSE:

The results from the Japanese Biliary Tract Cancer Statistics Registry from 1988 to 1998 were reported in 2002. In the present study, we report here selectively summarized data as an overview of the 2006 follow-up survey of the registered cases from 1998 to 2004 for information bearing on problems with the treatment of cancer of the biliary tract.

METHODS:

A total of 5,584 patients were registered from 1998 to 2004. The site of cancer was the bile duct in 2,732 patients, the gallbladder in 2,067, and the papilla of Vater in 785. Those cases were analyzed with regard to patient survival according to the extent of tumor invasion (pT), the extent of lymph node metastasis (pN) and the stage.

RESULTS:

The five-year survival rate after surgical resection was 33.1% for bile duct cancer, 41.6% for gallbladder cancer, and 52.8% for cancer of the papilla of Vater. For hilar or superior bile duct cancer, the 5-year survival rate was lower with an increase in the pT, pN and f stage, except pT3 vs. pT4, pN1 vs. pN2 and stage III vs. stage IVa. For middle or distal bile duct cancer, the 5-year survival rate was lower with increase in pT, pN and f stage, except pT2 vs. pT3, pN2 vs. pN3, stage II vs. stage III and stage III vs. stage IVa. For gallbladder cancer, the 5-year survival rate was lower with increase in pT, pN and f stage. For cancer of the papilla of Vater, the 5-year survival rate was lower with increase in pT, pN and f stage, except pT1 vs. pT2, pN1 vs. pN2, and stage III vs. stage IVa.

CONCLUSIONS:

In the present study, the outcomes of surgical treatment were better than that of the previous report from Japan and foreign countries. The pT, pN and stage of gallbladder cancer are well defined. However, there were no significant differences in some groups of those of bile duct cancer and cancer of the papilla of Vater.
