RESUMEN
PURPOSE: The aim of this study was to investigate the factors predictive of clinical outcome in advanced hepatocellular carcinoma patients receiving ramucirumab treatment. METHODS: We conducted a retrospective study using a multi-institutional electronic medical records database in Taiwan. We included advanced HCC patients newly receiving ramucirumab as second-line or beyond systemic therapy between January 2016 and February 2022. The clinical outcomes were median progression-free survival (PFS) based on the modified Response Evaluation Criteria in Solid Tumors (mRECIST), overall survival (OS) and adverse events. We applied Kaplan-Meier methods to estimate median PFS and OS. Uni-variable and multi-variable Cox regression models were applied to identify the prognostic factors. RESULTS: We included 39 ramucirumab naive users with a median age of 65.5 (IQR: 57.0-71.0) years and treatment time of 5.0 (3.0-7.0) cycles, of whom 82.1% were male and 84.6% were Barcelona Clinic Liver Cancer (BCLC) stage C. After median follow-up time of 6.0 months, 33.3% of patients' AFP level had decreased more than 20% within 12 weeks. The median PFS and OS were 4.1 months and non-reach, respectively. Moreover, tumor burden beyond the up-to-11 criteria (HR: 2.95, 95% CI: 1.04-8.38) and a decrease in estimated glomerular filtration rate of more than 10% within 12 weeks (HR: 0.31, 0.11-0.88) were significantly related to PFS in the multi-variable analysis. No patient discontinued ramucirumab during the treatment on account of side effects. CONCLUSION: Ramucirumab was an effective treatment option with good AFP response for advanced HCC patients in real-world experience. Tumor burden beyond the up-to-11 criteria and a decrease in estimated glomerular filtration rate were independent predictive factors for progression-free survival.
