Background/Aims: The definition of early extrahepatic bile duct cancer might be different from that of other gastrointestinal cancer because of the differences of histologic features including the lack of muscularis mucosa and submucosal layer in bile duct. The purpose of this study was to evaluate the concept of early extrahepatic bile duct cancer in Korea. Methods: We evaluated seventynine cases of extrahepatic bile duct cancer who had received curative resection in Severence Hospital, Yonsei University from March 1986 to October 2005. We retrosptectively reviewed the medical records and analyzed variable prognostic factors to define early extrahepatic bile duct cancer. Results: Invasion limited to the mucosa was noted in 5 cases (6.3%), fibromuscular layer in 12 cases (15.2%), adventitia of fibromuscular layer and serosa in 26 cases (32.9%), and invasion of adjacent organs in 36 cases (45.6%). Disease free 5-year survival according to the depth of invasion were 80.7% in tumor confined within mucosa, 80.0% within fibromuscular layer, 57.2% within adventitia of fibromuscular layer and serosa, and 51.5% in tumor with invasion of adjacent organ. There was no significant difference in the survival rate between patients with tumor confined to mucosa and patients with tumor invasion limited to the fibromuscular layer. However, the survival rate of patients with tumor limited to the mucosa or fibromuscular layer was significantly higher than that of patients with tumor invaded beyond fibromusular layer. In early cancer, there were more papillary polypoid type in gross finding and papillary adenocarcinoma in pathologic finding when compared to advanced cancer. Conclusions: Early extrahepatic bile duct cancer can be defined as the tumor invasion limited to the mucosa and fibromuscular layer.
