Core Tip

Core tip: Historically, prognosis after resection has been largely assessed based on preoperative clinicopathologic features. Data validating the prognostic value of patient and tumor specific factors have been mixed, with many recent studies showing these scoring systems to correlate poorly with survival. Rather, there has been an emerging interest in biological or molecular markers of prognosis to more effectively assess patient prognosis after resection of colorectal liver metastasis. In this review, we discuss past, present, and possible future markers of prognosis among colorectal cancer patients with liver metastasis undergoing resection with curative intent.
