BACKGROUNDS/AIMS: Although the survival rate after surgical resection of peripheral cholangiocarcinoma is low, surgical resection is only potentially curative therapy. The aim of this study is to evaluate clinicopathological factors affecting survival after surgical resection of peripheral cholangiocarcinoma. METHODS: Between February 1990 and December 2005, surgical intervention with curative intent was performed on 318 patients and 292 patients underwent resection. We retrospectively analyzed survival data of 318 patients and clinicopathological factors affecting survival by reviewing the medical record. RESULTS: Among the 292 cases of resection, curative resection with tumor-free margin (R0) has been resulted in 221 cases. The 1-, 3-, 5- and 10-year survival rate of R0 resection were 74.9, 46.9, 36.9 and 15.2%, respectively. The survival rate of patient undergoing R0 resection was significantly better than that of R1, R2 or nonresection. Multivariate analysis showed that curative resectability, macroscopic type of tumor and lymph node metastasis were statically significant independent prognostic factors. CONCLUSIONS: The survival after surgical resection of peripheral cholangiocarcinoma depends on curability of surgical resection, macroscopic type of tumor and status of lymph node. Particullary in R0 resection for intraductal growth type without lymph node metastasis, there is great chance for long-term survival. Surgical resection attaining tumor free margin should be attempted if liver function and general condition of patient are acceptable for hepatectomy.

BACKGROUND/AIMS: Combined hepatocellular and cholangiocarcinoma (HCC-CC) is a rare form of primary liver carcinoma which contains characteristics of both hepatocellular carcinoma and cholangiocarcinoma. The aim of this study was to evaluate the prognostic factors of combined HCC-CC after curative resection. METHODS: Between January 1987 and December 2005, pathologically confirmed combined HCC-CC patients who underwent curative resection at Seoul National University Hospital were evaluated. We reviewed the medical records and evaluated the time-to-recurrence (TTR), overall survival (OS) and prognostic factors of combined HCC-CC. RESULTS: A total of 31 patients were evaluated (M:F=27:4; median age, 61 years). According to the American Joint Committee on Cancer system, patients with stage I, II, III(A), III(B) and III(C) at the time of resection were 4, 16, 7, 2 and 2, respectively. Twenty six patients (83.9%) had tumor recurrence during the follow-up period and their median TTR was 5.7 months. Twenty one patients received additional treatment while 5 patients did not. As a result, median OS was 21.6 months and 3 year survival rate was 15.4%. In multivariate analysis, stage III than stage I or II at resection was an independent prognostic factor associated with shortened TTR (p<0.01). Older age (p=0.03), stage III(C) rather than stage I, II, III(A) at time of resection (p=0.02), and Child-Pugh B rather than A (p<0.01) were independent prognostic factors associated with shortened OS. CONCLUSIONS: Even after curative resections, patients with combined HCC-CC show poor prognosis with early recurrence and poor survival. However, surgical treatment should be warranted for relatively young patients in early stage with well preserved liver function.
