Negative surgical margin improved long-term survival of colorectal cancer liver metastases after hepatic resection: a systematic review and meta-analysis

摘要

The need to achieve a tumor-free margin of a parts per thousand yen1 mm (R0) for colorectal liver metastases (CRLM) after hepatic resection has been questioned recently. This study conducted a meta-analysis to determine whether status of the surgical margin still influenced the long-term outcome of survival and recurrence rate.
