Non-Surgical Locoregional Therapies Alone or in Combination with Systemic Therapy in Patients with Hepatocellular Carcinoma.

ABSTRACT: Hepatocellular carcinoma (HCC) is the most common primary liver cancer, representing the third-leading cause of cancer-related deaths worldwide. Curative intent treatment options for patients with HCC include liver transplantation, resection and ablation of small lesions. Other potentially curative therapies include cryoablation, microwave ablation and percutaneous alcohol injection. For locally advanced disease, different arterially directed therapies including transarterial chemoembolization and selective internal radiation therapy, plus external beam radiation including three-dimensional conformal radiation therapy, intensity-modulated radiation therapy, stereotactic body radiation therapy and proton beam therapy, are available or studied. Systemic therapies based on checkpoint inhibitors and tyrosine kinase inhibitors are available for the management of metastatic HCC and sometimes for locally advanced disease. Combinations of locoregional therapies with systemic drugs are currently the subject of several clinical trials.

Project description:Atezolizumab plus bevacizumab (A+B) is used to treat unresectable hepatocellular carcinoma (HCC), but the optimal rescue therapy after A+B remains unclear. Combining locoregional therapy (LRT) with systemic treatment has been shown to improve tumor control, but the role in patients who fail A+B is unknown. We retrospectively enrolled patients who experienced radiological progression after A+B. Objective response rate (ORR), disease control rate (DCR), post progression survival (PPS), and secondary progression-free survival (PFS) were evaluated by modified RECIST. Inverse probability weighting (IPW) was used to balance baseline clinical features. A total of 61 patients were enrolled with a median age of 60.7 years, 83.6% male, 88.5% viral hepatitis-related, and 60.7% without prior systemic treatment before A+B. Patients receiving sequential therapies had significantly longer PPS than supportive care (10.5 vs. 2.3 months, P<0.0001). Among 37 patients received sequential systemic treatment, 18 received combined LRT. The median follow-up after post A+B failure was 6.6 months. The combined LRT group had higher ORR (27.8 vs. 0%, P=0.0197) and DCR (72.2 vs. 26.3%, P=0.0052) than systemic alone group. The median PPS and secondary PFS were significantly longer in combined LRT group (PPS: 12.2 vs. 5.8 months, P=0.0070; PFS: 5.0 vs. 2.6 months, P=0.0134) than systemic alone group. After IPW analysis, patients with combined LRT had superior PPS and secondary PFS. The incidence rates of AEs were higher in LRT combination compared to systemic alone (any grade AEs: 94.4 vs. 63.2%, P=0.0422; severe AEs: 33.3 vs. 5.3%, P=0.0422). No significant albumin-bilirubin index changed in the first 3 months in combined LRT group (0.966 [0.647-1.443], P=0.867) though a trend of deterioration in systemic alone group. In conclusion, sequential systemic therapy provides survival benefits after A+B failure. Furthermore, combining LRT with systemic treatment could provide better tumor responses and survival benefits with acceptable toxicity than systemic therapy alone.
