Survival After Resection of Multiple Bilobar Hepatic Metastases From Colorectal Carcinoma

Resection of complex hepatic metastases, as defined in this study, results in a 5-year survival rate of 37% and confers the same survival benefit as does resection of limited hepatic metastases. The surgical death rate for this aggressive approach is significantly higher if extended lobar resections are necessary and if concomitant colorectal resection is performed. Patients who have complex hepatic metastases at the time of diagnosis of the primary colorectal cancer and who would require extended hepatic lobectomy should have hepatic resection delayed for at least 3 months after colon resection.
