Background Hepatolithiasis‐associated intrahepatic cholangiocarcinoma (IHHCC) has a poor prognosis, because of lower curative resection rate when diagnosed in the advanced stage. There has been insufficient data regarding prognostic factors and the impact of palliative resection on its outcome. Methods A retrospective analysis of 78 eligible patients with stage IV IHHCC was performed. The potential prognostic factors were assessed by univariate and multivariate analyses. Patients were divided into groups A (margin positive) and B (nonresection) based on surgical methods. Demographic and operative data were compared. Results Of 78 surgeries, R1 was achieved in 11, R2 in 21 and nonresection in 46 patients. Median overall survival (OS) of the entire cohort was 10.5 months. Surgery ( P  < 0.01), tumor differentiation ( P  = 0.03), AJCC stage ( P  < 0.01), and serum CEA levels ( P  < 0.01) were independent prognostic factors. Significant differences were achieved in OS ( P  < 0.01), operation time ( P  < 0.01), estimated blood loss ( P  < 0.01), and postoperative complications ( P  = 0.02) between groups A and B. Conclusions For patients with stage IV IHHCC, palliative resection is a rational and effective treatment. Normal serum CEA levels, higher tumor differentiation, and stage IVa predict good prognosis in stage IV IHHCC. J. Surg. Oncol. 2014 109:494–499 . © 2013 Wiley Periodicals, Inc.
