Abstract
BACKGROUND

Systemic therapies have improved management of hepatocellular carcinoma (HCC); however, further improvements in overall survival for first-line treatment of primary unresectable HCC remain necessary.

AIM

To evaluate the safety and efficacy of hepatic arterial infusion chemotherapy combined with lenvatinib and pembrolizumab for treating primary unresectable HCC.

METHODS

This retrospective study analyzed data from 38 patients who received this triplet therapy at Sun Yat-sen Memorial Hospital between December 2019 and March 2022.

RESULTS

The overall response rate was 50.0% (Response Evaluation Criteria in Solid Tumors criteria) and 52.6% (modified Response Evaluation Criteria in Solid Tumors criteria), with a disease control rate of 97.4%. The successful conversion rate, defined as meeting all prespecified criteria for surgical resectability was 50.0%. Consequently, the surgical conversion rate, reflecting the proportion of patients who underwent subsequent radical resection, was 44.7%. The pathological complete response rate was 7.9%. Grade III/IV treatment-related adverse events occurred in 10.53% of patients, with no perioperative deaths or major complications. The successful conversion group demonstrated significantly higher 1-year, 2-year, and 3-year survival rates compared to the unsuccessful conversion group.

CONCLUSION

Combination of hepatic arterial infusion chemotherapy, lenvatinib, and pembrolizumab is a promising and well-tolerated treatment strategy for primary unresectable HCC.

Core Tip: This retrospective study of 38 patients with initially unresectable hepatocellular carcinoma treated with hepatic arterial infusion chemotherapy, lenvatinib and pembrolizumab showed promising results. The overall response rate was 50.0%-52.6% with a disease control rate of 97.4%. The conversion to surgery rate was 44.7%, with a pathological complete response rate of 7.9%. Treatment was well-tolerated, with only 10.5% experiencing grade III/IV adverse events. Patients achieving successful conversion had significantly better long-term survival.
