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.

Aims: Our aim was to assess the impact of clinically significant PHT on postoperative complication and prognosis in HCC patients who undergo HR.

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.
