Background and aims:
Hepatic resection is one of the best curative treatments in well-selected patients with hepatocellular carcinoma (HCC) and cirrhosis. The risk of decompensation after resection has major impact over the outcome of these patients. Portal hypertension is the main risk factor for decompensation and it is still a matter of debate which is the best method to identify patients at risk.
The aim of the study was to compare different methods for risk assessment in patients with HCC submitted to hepatic resection.
Patients and methods:
Since January 2016 94 consecutive patients were diagnosed with HCC and were prospectively registered. Thirty-three patients were submitted to hepatic resection and among them: 22 were screened for esophageal varices (EV), 13 patients were evaluated by hepatic venous pressure gradient (HVPG) and 18 by transient elastography.
Results:
Among the 33 included patients,8/22 (35%) had EV, 6/13 (46%) had clinical significant portal hypertension (HVPG>10mmHg) and 9 (30%) had platelet count 100.000/mmc. During follow-up 12 (36%)patiens presented decompensation (3 variceal bleeding, 7 ascites, 6 renal dysfunction and 1 jaundice). In univariate analysis HVPG, liver stiffness, platelet count, ALT and AST were associated with decompensation. Neither presence of EV(40% correctly classified, p=0.13) or platelet count 100.000/mmc (64% correctly classified, p=0.08)were accurate enough to predict decompensation. Presence of CSPH assessed by HVPG correctly classified 92% of patients (p=0.002). There was no difference between HVPG and transient elastography regarding the performances (AUROC) for predicting decompensation, 0.91 (95%CI: 0.74-1, p=0.012) and 0.93 (95%CI: 0.80-1, p=0.007), respectively.
Conclusion:
HVPG is the best prognostic factor for the risk of decompensation after hepatic resection in patient with HCC and cirrhosis, while surrogate markers, as presence of EV of low platelet count, is not accurate enough. Liver stiffness measurement with transient elastography is a promising prognostic tool.
