Summary Objective: We aimed to evaluate oncological outcomes after repeat metastasec-tomies in patients having undergone previous resections for colorectal cancer metastases. Methods: We examined 248 patients who underwent metastasectomies for lung and/or liver metastases at our center during a 7-year period, from January 2005 to December 2011. Recurrence-free survival 1 (RFS1) after the metastasectomy for the initial recurrence, recurrence-free survival 2 (RFS2) after the second, and recurrence-free survival 3 (RFS3) after the third repeated resections for recurrence were assessed. The overall survival (OS) rate after the first metastasectomy for the first recurrence (OS) was also assessed.
Conclusion: A second metastasectomy should be considered the optimal treatment for a sec-ond recurrence. However, careful considerations should be made before performing a third metastasectomy.
