Yao and colleagues confirmed that there are well-known risk factors for recurrence of HCC after surgical resection. They retrospectively analyzed 1424 patients who underwent resection with curative intent for Barcelona Clinical Liver Cancer (BCLC) stage 0/A HCC in several centers in China. Of those patients, 679 (47.7%) developed recurrence at a median follow-up of 54.8 months, including 408 (60.1%) with an early recurrence (≤ 2 years after surgery) and 271 (39.9%) with a late recurrence (> 2 years). Cirrhosis (adjusted hazard ratio [aHR] 1.49; P < .001), preoperative alpha-fetoprotein (AFP) level > 400 µg/L (aHR 1.28; P = .004), tumor size > 5 cm (aHR 1.74; P < .001), the presence of satellite nodules (aHR 1.35; P = .040), multiple tumors (aHR 1.63; P = .015), microvascular invasion (aHR 1.51; P < .001), and intraoperative blood transfusion (aHR 1.50; P = .013) were identified as independent risk factors associated with postoperative HCC recurrence. The authors concluded that those patients with risk factors for recurrence would benefit from more intensive surveillance and potentially additional liver-directed therapy with curative intent.
Not all patients with hepatitis C virus (HCV) infection and HCC are offered antiviral therapy. Takaura and colleagues confirmed that active HCV infection worsens the prognosis of patients with very early-stage HCC who undergo treatment with radiofrequency ablation (RFA). In this single-center retrospective study, 302 patients with BCLC stage 0 HCC who underwent RFA were analyzed. Of those patients, 195 had evidence of HCV, and 132 had an active infection. The authors concluded that active HCV infection was a significant risk factor for shorter overall survival (aHR 2.17; P = .003) and early recurrence of HCC (aHR 1.47; P = .022). Patients with active HCV infection had a shorter median overall survival (66 months vs 145 months) and recurrence-free survival (20 months vs 31 months) (both P < .001). Therefore, treatment of active HCV should be offered to patients even after the development of HCC.
Kuroda and colleagues retrospectively analyzed a multicenter cohort of 247 patients with unresectable HCC treated with lenvatinib between 2018 and 2020. Out of those, 63 patients who received lenvatinib and transarterial chemoembolization (TACE) sequential therapy were propensity-score matched to those receiving lenvatinib monotherapy. The overall survival and progression-free survival in the sequential group were significantly higher than those in the lenvatinib monotherapy group, 31.2 (26.4-34.3) vs 15.7 (13.1-19.4) months and 12.2 (8.5-17.3) vs 6.7 (5.3-10.2) months ( P = .002 and P = .037), respectively. Multivariate analysis showed that the deep response was independently associated with the initial response to levatinib; the partial response showed an odds ratio of 13.75 (95% CI 0.41-1.32; P < .001). The authors concluded that sequential therapy might provide more clinical benefits than lenvatinib monotherapy in patients who responded to initial lenvatinib treatment, with objective response to initial lenvatinib being an independent factor predicting sequential therapy deep response.
