Prognosis of patients undergoing resection of both hepatic and pulmonary metastases from colorectal cancer

: This retrospective study evaluated the prognosis of patients undergoing resection of both hepatic and pulmonary metastases from colorectal cancer. The subjects were 14 patients who underwent resection of both hepatic and pulmonary metastases from colorectal cancer between January 1991 and January 2008. The range of patient age at first metastatectomy was 48- 73-years-old (median 59). The ratio of males to females was 4 to 3. Hepatic metastatectomy proceeded to pulmonary metastatectomy in 10 cases, while pulmonary metastatectomy was performed first in 4 cases. The median duration of relapse-free survival and overall survival after the second metastatectomy was 11.2 months and 20.4 months, respectively. The overall survival after the second metastatectomy tended to correlate with the relapse-free survival after the first metastatectomy (rs=0.55, p=0.08). In conclusion, relapse-free survival after the first metastatectomy should be considered when a second metastatectomy is scheduled in patients with both hepatic and pulmonary metastases from colorectal cancer.
