BACKGROUND: Biliary tract cancer is uncommon, but has a high rate of early recurrence and a poor prognosis. There is only limited information on patients surviving more than 5 years after resection.
METHODS: We report a patient who developed recurrence 8 years after resection of cholangiocarcinoma. Descriptions of late recurrence after excision of cholangiocarcinoma are reviewed.
RESULTS: Few long-term survivors with biliary tract cancer have been reported. The survivors tend to have well differentiated or papillary tumors. The present case had no recurrence for 8 years despite poor prognostic factors including poor differentiation, invasion through the muscle wall and perineural invasion. It has been suggested that tumor cells left after the first operation grow and present as late recurrence. There is a need to differentiate a new primary and field change from recurrence of the previous tumor.
CONCLUSIONS: Long-term follow-up after resection of cholangiocarcinoma is needed because late recurrence after 5 years occurs. The mortality rate between 5 and 10 years after resection of cholangiocarcinoma ranges from 6% to 43% in different series. Early detection of local recurrence may give an opportunity for further surgical resection.
