P-290Simultaneous versus staged resections of liver metastases in patients with advanced colorectal cancer

Introduction: Surgical management of metastatic colorectal cancer remains the best method to use which significantly improves overall 5-year survival. There are two well-known possible approaches of surgical treatment of patients with synchronous colorectal liver metastasis. The former includes synchronous resection of the colorectal primary with the following resection of the liver metastases and the latter is a staged resection approach. However, at present the issue of feasibility and effectiveness of simultaneous operations for metastatic liver lesions in patients with synchronous metastatic colorectal cancer (SMCLC) is negotiated and remains uncertain. This study aimed to compare the surgical outcomes and survival benefit between synchronous and staged resections of the colorectal liver metastases.
