Prognostic Impact of Anatomic Resection for Hepatocellular Carcinoma

To evaluate the prognostic impact of anatomic versus nonanatomic resection on the patients' survival after resection of a single hepatocellular carcinoma (HCC). SUMMARY OF BACKGROUND DATA: Anatomic resection is a reasonable treatment option for HCC; however, its clinical significance remains to be confirmed.

Curative hepatic resection was performed for a single HCC in 210 patients; the patients were classified into the anatomic resection (n = 156) and nonanatomic resection (n = 54) groups. In 84 patients assigned to the anatomic resection group, segmentectomy or subsegmentectomy was performed. We evaluated the outcome of anatomic resection, including segmentectomy and subsegmentectomy, in comparison with that of nonanatomic resection, by the multivariate analysis taking into consideration 14 other clinical factors.
