Primary Tumor Resection in Patients Presenting With Metastatic Colorectal Cancer

Abstract

Most patients presenting with mCRC underwent primary resection. Colonic tumors, obstruction, and bleeding were associated with resection. In situ primaries conferred more complications, despite similar use of radiation in cases of rectal cancer. Unresected patients were less likely to receive doublet chemotherapy or metastatectomy, and had inferior survival.
