Long-term oncologic outcomes for simultaneous resection of synchronous metastatic liver and primary colorectal cancer.

Background: Twenty-five percent of patients with colorectal cancer present with simultaneous liver metastasis. Complete resection is the only potential curative treatment. Due to improvements in operative and perioperative management, simultaneous liver and colon resections are an accepted procedure at specialized centers for selected patients.

Simultaneous resection for rectal cancer with synchronous liver metastasis is a safe procedure.

Background: One quarter of colorectal cancer patients will present with liver metastasis at the time of diagnosis. Recent studies have shown that simultaneous resections are safe and feasible for stage IV colon cancer. Limited data are available for simultaneous surgery in stage IV rectal cancer patients.
