Predictors for early recurrence beyond up-to-7 or distant metastasis after hepatocellular carcinoma resection:...

The recurrence rate after curative resection for hepatocellular carcinoma (HCC) reaches over 70% after 5 years and early recurrence (within 1 year) is now recognized as having a poor prognosis and has limited treatment options.

We retrospectively reviewed 184 consecutive patients who underwent curative hepatic resection for HCC. Severe early recurrence was defined as multiple (beyond up-to-7) liver recurrence or distant metastasis after hepatic resection within 1 year. We divided the participants into two groups according to severe early recurrence and analyzed clinicopathological and long-term outcomes.

Among the patients with multiple or distant metastasis (n = 59), 49 patients (83%) had recurrence within 1 year. Overall survival (OS) and recurrence-free survival (RFS) were significantly worse in the severe early recurrence group than in the others group. Logistic regression analysis revealed that severe early recurrence was significantly associated with macroscopic vascular invasion (MVI), tumor burden score (TBS) > 4.70, and ALBI grade 2. In patients with scores of 2 and 3 (the sum of the three factors), OS and RFS rates were significantly poorer than those of patients with scores of 0 or 1. Positive predictive value and negative predictive value for severe early recurrence was 68.4% and 84.2%, respectively. Furthermore, a validation study demonstrated that cases with these factors were at high risk of severe early recurrence and had poor prognosis.

In this retrospective analysis, MVI, TBS, and ALBI could predict severe early recurrence after hepatic resection for HCC, and patients with these risk factors had a poor prognosis.
