Is Adjuvant Cellular Immunotherapy Essential after TACE-Predominant Minimally-Invasive Treatment for Hepatocellular Carcinoma? A Systematic Meta-Analysis of Studies Including 1774 Patients.

ABSTRACT:

Purpose

Cellular immunotherapy has appeared to be a promising modality for the treatment of malignant tumor. The objective of this study was to evaluate the efficacy of cellular immunotherapy combined with minimally invasive therapy.

Methods

We searched PubMed, Web of Science and The Cochrane Library through March 2016 for relevant studies. Short-term efficacy (the disease control rate, the control rate of quality life and the AFP descent rate) and long-term efficacy (overall survival (OS) and progression-free survival (PFS) rate) were compared as the major outcome measures. The meta-analysis was performed using Review Manager 5.3.

Results

A total of 1174 references in 3 databases were found of which 19 individual studies with 1774 HCC patients enrolled in this meta-analysis. Meta-analysis results showed that cellular immunotherapy combined with minimally-invasive treatment significantly improved the measures of short-term response (the disease control rate (OR = 5.91, P = 0.007), the control rate of quality lift (OR = 3.38, P = 0.003) and the AFP descent rate (OR = 4.48, P = 0.02)). Also higher 6-month PFS (OR = 2.78, P = 0.05), ?12-month PFS (OR = 3.56, P<0.00001) rate and 6-month OS (OR = 2.81, P = 0.0009), 12-month OS (OR = 3.05, P<0.00001) and 24-month OS (OR = 3.52, P<0.0001) rate were observed in patients undergoing cellular immunotherapy.

Conclusions

This meta-analysis suggested that cellular immunotherapy is a feasible adjuvant treatment that could be beneficial for the improvement of the clinical outcomes for hepatocellular carcinoma (HCC) patients after minimally invasive treatment, including short-term response and long-term survival.

Project description:Background and aimStandardized approach to postoperative adjuvant therapy for hepatocellular carcinoma (HCC) remains elusive. This study endeavors to examine the effects of postoperative PD-1 adjuvant therapy on the short-term and long-term prognosis of patients at a heightened risk of post-surgical recurrence.MethodsThe data of HCC patients who underwent hepatectomy at our center from June 2018 to March 2023 were collected from the hospital database. Propensity score matching (PSM) was employed to perform a 1:1 match between the postoperative anti-PD-1 antibody group and the postoperative non-anti-PD-1 antibody group. Kaplan-Meier method was utilized to compare the overall survival (OS) and recurrence-free survival (RFS) between the two groups. Cox regression analysis was conducted to identify the prognostic factors affecting patient outcomes. Subgroup analyses were performed for different high-risk factors.ResultsAmong the 446 patients included in the study, 122 patients received adjuvant therapy with postoperative anti-PD-1 antibodies. After PSM, the PD-1 group had postoperative 1-year, 2-year, 3-year, and 4-year OS rates of 93.1%, 86.8%, 78.2%, and 51.1%, respectively, while the non-PD-1 group had rates of 85.3%, 70.2%, 47.7%, and 30.0%. The PD-1 group had postoperative 1-year, 2-year, 3-year, and 4-year RFS rates of 81.7%, 77.0%, 52.3%, and 23.1%, respectively, whereas the non-PD-1 group had rates of 68.4%, 47.7%, and 25.8% in 1-year, 2-year, 3-year. A multifactorial Cox regression analysis revealed that postoperative PD-1 use was a prognostic protective factor associated with OS and RFS. Subgroup analysis results indicated that HCC patients with high recurrence risks significantly benefited from postoperative anti-PD-1 antibody treatment in terms of OS and RFS.ConclusionFor HCC patients with high-risk recurrence factors and undergoing hepatectomy, postoperative adjuvant therapy with anti-PD-1 antibodies can effectively improve their survival prognosis.
