Review Meta Analysis
Meta-analysis of outcomes following resection of the primary tumour in patients presenting with metastatic colorectal cancer.
It is not clear whether resection of the primary tumour (when there are metastases) alters survival and/or whether resection is associated with increased morbidity. This systematic review and meta-analysis assessed the prognostic value of primary tumour resection in patients presenting with metastatic colorectal cancer. ⋯ Primary tumour resection may provide a modest survival advantage in patients presenting with metastatic colorectal cancer.
