3566Background: The overall survival of patients with stage IV colorectal cancer (both in unresectable and resectable settings) has been increasing over recent decades due to improvements in chemotherapy, liver surgery and other liver-directed therapies. As a result of more patients living longer, there is a need to refine prognostic information to more accurately predict survival to assist multi-disciplinary cancer management teams in treatment decisions but also for patient quality of life. Methods: We performed a retrospective analysis of all patients with stage IV colorectal cancer seen at Rutgers Cancer Institute of New Jersey between Jan 1, 2005 to March 10, 2015 by ICD-9 code (N = 318 patients). This included patients who were deemed unresectable and patients who were resected with curative intent. Our study population was patients with documented survival for > 24 months (N = 158). Variables gathered included patient demographics, disease related (primary location, KRAS status, metastasis location...
