PURPOSE: The purpose of this study was to investigate survival outcomes and safety after chemoembolization using irinotecan-loaded small-size beads (DEB-IRI) in patients with colorectal liver metastases unresponsive to standard chemotherapy.
MATERIALS AND METHODS: Between December 2013 and August 2019, fifty-five patients (32 males, median age 64.5 years) with pretreated colorectal liver metastases unresponsive to standard chemotherapy underwent 197 chemoembolization procedures (mean 3.6 ± 2.3 SD per patient). Thirty patients (30/55; 55%) had extrahepatic disease metastatic to the lungs, lymph nodes or peritoneum. Local tumor control was evaluated at 3, 6, 9 and 12 months. Median overall survival, survival rates at 1 and 2 year and adverse events were evaluated.
RESULTS: Local tumor control was achieved in 32/55 (58%), 12/55 (22%), 4/55 (7%) and 2/55 (4%) patients at 3, 6, 9 and 12 months, respectively. Median overall survival was 9.9 months (95% CI: 6.2-14.2 months) with 1- and 2-year survival rates of 45% and 15%, respectively. A total of 30 (15%) G1-G3 treatment-related adverse events occurred across all embolization procedures. No severe treatment-related adverse events occurred.
CONCLUSION: Chemoembolization using irinotecan-loaded small-size beads is a safe and effective procedure as a salvage treatment in patients with colorectal liver metastases, showing good results in terms of liver-specific progression free survival and overall survival.
