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, ⅢA, ⅢB and ⅢC 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 ⅢC rather than stage Ⅰ, Ⅱ, ⅢA 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.
Conclusion: 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. (Korean J Gastroenterol 2007;49:158-165)
