SURGERY: KRAS mutations and hepatic recurrence after treatment of colorectal liver metastases
Non-anatomical resection of colorectal liver metastases is the current preferred approach to maximize sparing of the hepatic parenchyma. A new study raises the question of whether resection in patients with KRAS-mutated colorectal liver metastases should be performed along segmental, anatomical lines to reduce the risk of local liver recurrence.
