Micro-Abstract: The present study examined the effect of primary tumor resection on overall survival of patients with metastatic colorectal cancer (mCRC). A total of 690 de novo and 373 metachronous mCRC patients treated with palliative intent were identified. For patients with de novo mCRC, primary tumor resection at diagnosis does not significantly improve overall survival when adjusting for known major prognostic factors.
