In a retrospective study we sought to determine prognostic factors related to survival in these patients. In 28 patients who underwent hepatic resection for intrahepatic cholangiocarcinoma, we investigated the relations of several histologic factors to patient survival by univariate and multivariate analyses. No deaths occurred during the first 30\u00a0days. Median and mean survival times following hepatectomy were 409 and 935\u00a0days, respectively. The respective survival rates at 1, 3, and 5 years were 57%, 27%, and 27%. Resection margin status, intrahepatic metastasis, lymph node involvement, and lymphatic invasion were significant predictors of outcome. In a multivariate analysis using the Cox proportional hazards model, only lymphatic invasion independently predicted survival. Curative resection with clear margins was found to prolong survival after surgery. Hepatectomy for intrahepatic cholangiocarcinoma without lymphatic invasion offers hope for long\u2010term survival.<\/jats:p>","DOI":"10.1007\/s00268-001-0042-3","type":"journal-article","created":{"date-parts":[[2003,10,27]],"date-time":"2003-10-27T18:08:51Z","timestamp":1067278131000},"page":"865-869","source":"Crossref","is-referenced-by-count":34,"title":["Histologic
