The role of clinically significant portal hypertension in hepatic resection for hepatocellular carcinoma patients: A propensity score matching analysis

Abstract

Background: Whether portal hypertension (PHT) is an appropriate contraindication for hepatic resection (HR) in hepatocellular carcinoma (HCC) patient is still under debate. Methods: Two hundred and nine HCC patients who underwent HR as the initial treatment were divided into two groups according to the presence (n = 102) or absence (n = 107) of clinically significant PHT. Propensity score matching (PSM) analysis was used to compare postoperative outcomes and survival. Results: Before PSM, PHT patients had higher rates of postoperative complication (43.1% vs. 23.4%; P = 0.002) and liver decompensation (37.3% vs. 17.8%; P = 0.002) with similar rates of recurrence-free survival (RFS; P = 0.369) and overall survival (OS; P = 0.205) compared with that of non-PHT patients. However, repeat analysis following PSM revealed similar rates of postoperative complication (32.2% vs. 39.0%; P = 0.442), liver decompensation (25.4% vs. 32.2%; P = 0.416), RFS (P = 0.481) and OS (P = 0.417; 59 patients in each group). Presence of PHT was not associated with complication by logistic regression analysis, or with overall survival by Cox regression analysis. Conclusions: The presence of clinically significant PHT had no impact on postoperative complication and prognosis, and should not be regarded as a contraindication for HR in HCC patients.
