Perioperative Chemotherapies for Patients with Colorectal Liver Metastasis

: Perioperative chemotherapies are expected to improve prognosis of patients with colorectal liver metastasis(CRLM). In patients with a resectable CRLM, the adjuvant chemotherapy with 5-FU/LV effectively prolongs DFS or RFS. In patients with unresectable CRLM, a neoadjuvant chemotherapy with high response rate and high liver resection rate, such as FOLFOX(or CAPOX, SOX)plus bevacizumab, FOLFOX/FOLFIRI plus cetuximab, or FOLFOXIRI plus bevacizumab, could be an optimal regimen for the conversion therapy.
