Perioperative Chemotherapy is Associated with Superior Overall Survival in Patients with Synchronous Colorectal Liver Metastases.

This study reveals a correlation between perioperative chemotherapy and superior OS in patients with liver-only CRLM, and shows that resection of the metastatic site was linked to better OS. Despite obvious cohort heterogeneity, the data can support a resection approach with additional, preferably peri- or preoperative systemic therapy for patients with CRLM.
