Abstract
AIM
This study aimed to evaluate efficacy and safety of raltitrexed-based transcatheter arterial chemoembolization (TACE) for intermediate and advanced hepatocellular carcinoma (HCC) using real-world evidence.
METHODS
All eligible HCC cases were collected from multiple centers in Chongqing, China, from January 2013 to December 2018 and divided into the raltitrexed group (raltitrexed + lobaplatin + pirarubicin) and control group (lobaplatin + pirarubicin). Propensity score matching (PSM) with a 1:1 ratio was used to eliminate the imbalance of potential confounding factors between groups. The primary end-point was overall survival (OS) and the secondary end-points were progression-free survival (PFS) and disease control rate.
RESULTS
The median follow-up period for patients in the raltitrexed and control groups was 8.7 and 5.9 months, respectively. After PSM, median OS was 10.0 months in the raltitrexed group and 7.0 months in the control group (p = 0.002). The 6-month, 1-year, and 2-year OS rates of the raltitrexed group were significantly higher than those of the control group (78.2% vs. 60.9%, p = 0.010; 43.5% vs. 22.8%, p = 0.030; and 17.4% vs. 2.2% p = 0.001, respectively). Multivariate analysis of these propensity score-matched HCC patients revealed treatment, age, tumor size, lipiodol accumulation, and the number of TACE cycles as independent predictors of OS (all p < 0.05). The disease control rate of the raltitrexed and control groups was 87.4% and 65.8%, respectively (p < 0.001).
CONCLUSIONS
Raltitrexed-based TACE can prolong the OS of patients with intermediate and advanced HCC in a real-world clinical setting, and is safe and tolerable.
