Hepatic arterial infusion (HAI) chemotherapy, first introduced in the 1980s, has gained recognition as an effective locoregional treatment for colorectal liver metastasis (CRLM). Initially used for unresectable liver metastases, HAI's application has expanded to the adjuvant setting following hepatic resection, with early studies indicating improved hepatic disease-free survival. Recent research demonstrates that combining HAI with modern systemic therapies enhances conversion to resectability and prolongs both recurrence-free and overall survival, even in heavily pretreated patients with diverse RAS mutational statuses. Personalization through approaches like microsatellite instability status and dose modifications further optimize outcomes. However, the complexity of HAI requires expertise across multidisciplinary teams, limiting its widespread adoption to specialized centers. Ongoing clinical trials continue to investigate HAI's role in CRLM management, highlighting its potential to become a cornerstone of liver-directed therapy. We explore how HAI chemotherapy, in combination with personalized medicine, can advance treatment strategies for metastatic colorectal cancer.
