Abstract

Background: Some reports support resection combined with cryotherapy for patients with multiple bilobar colorectal liver metastases (CRLM) that would otherwise be ineligible for curative treatments. This series demonstrates long-term results of 415 patients with CRLM who underwent resection with or without cryotherapy. Methods: Between April 1990 and January 2006, 291 patients were treated with resection only and 124 patients with combined resection and cryotherapy. Recurrence and survival outcomes were compared. Kaplan-Meier and Cox-regression analyses were used to identify significant prognostic indicators for survival. Results: Median length of follow-up was 25 months (range 1-124 months). The 30-day perioperative mortality rate was 3.1%. Overall median survival was 32 months (range 1-124 months), with 1-, 3- and 5-year survival values of 85%, 45% and 29%, respectively. The overall recurrence rates were 66% and 78% for resection and resection/cryotherapy groups, respectively. For the resection group, the median survival was 34 months, with 1-, 3- and 5- year survival values of 88%, 47% and 32%, respectively. The median survival for the resection/cryotherapy group was 29 months, with 1-, 3- and 5-year survival values of 84%, 43% and 24%, respectively (P = 0.206). Five factors were independently associated with an improved survival: absence of extrahepatic disease at diagnosis, well- or moderately-differentiated colorectal cancer, largest lesion size being 4 cm or less, a postoperative CEA of 5 ng/ml or less and absence of liver recurrence. Conclusions: Long-term survival results of resection combined with cryotherapy for multiple bilobar CRLM are comparable to that of resection alone in selected patients.
