Abstract

Purpose

Lack of evidence on the benefit of stereotactic body radiotherapy (SBRT) in combination with lenvatinib for advanced hepatocellular carcinoma (HCC). Our research compared the efficacy and safety of SBRT plus lenvatinib versus SBRT alone in clinical practice for the treatment of advanced HCC.

Methods

Propensity score matching (PSM) analysis was used to reduce selection bias. Overall survival (OS), progression-free survival (PFS), intrahepatic PFS (IHPFS), and objective response rate (ORR) were compared between the two groups. Additionally, safety profiles were also evaluated in the two groups.

Results

After PSM, 35 patients from each group were selected and the date was compared. Compared with the SBRT alone group, the median OS, PFS, and IHPFS were significantly prolonged in SBRT plus lenvatinib group (median OS 16.8 vs. 11.0 months, pOS = 0.043; median PFS 9.1 vs. 3.7 months, pPFS < 0.001; median IHPFS 9.5 vs. 4.2 months, pIHPFS = 0.004). The 6- and 12-month OS rates were 91.4% and 68.6% in the combined therapy group and 82.9% and 48.6% in the monotherapy group, respectively. The 6- and 12-month PFS rates were 68.6% and 34.3% in the combined therapy group and 31.4% and 8.6% in the monotherapy group, respectively. Furthermore, a higher ORR was observed in SBRT plus lenvatinib group (54.29% vs. 22.86%, p = 0.007). Subgroup analysis of patients with macroscopic vascular invasion (MVI) also had similar results. Moreover, most adverse events (AEs) were mild-to-moderate and manageable in the SBRT plus lenvatinib group.

Conclusion

SBRT plus lenvatinib is expected to significantly improve OS, PFS, IHPFS, and ORR for patients with advanced HCC when compared to SBRT alone, with manageable adverse effects.
