Repeat hepatectomy for recurrent colorectal metastases.
Recurrence rates after hepatic resection in patients with colorectal metastases are reported to range from 47% to 80%. Hepatic recurrence is seen in 35% to 50% of patients. Aggressive surgical resection appears to be a worthwhile treatment in patients with recurrent hepatic metastases to promote longer patient survival because surgical resection remains the only curative therapy available. This is a retrospective review of our experience with 15 patients undergoing repeat hepatic resection culled from 67 patients undergoing initial hepatectomy for metastatic colorectal cancer. Of 67 patients who underwent hepatectomy for colorectal hepatic metastases, 33 developed hepatic recurrence at a median interval of 23 months (range 1-176 months) after the first hepatectomy. The second hepatectomy was performed in 15 patients 5 to 29 months after the first hepatectomy, with no mortality. The mean operating time and blood loss at the second hepatectomy were similar to those at the first hepatectomy. The mean hospital stay at the second hepatectomy was significantly shorter than that at the first hepatectomy. The cumulative survival rate for the 15 patients was 42.4% at 3 years and 21.2% at 5 years, respectively, which compared favorably with the survival rate of the 67 patients who underwent initial hepatectomy. Patients who underwent the second hepatectomy had significantly higher survival rates from the first hepatectomy than the 18 patients with unresectable hepatic recurrence. Repeat hepatectomy can be performed safely and provides long-term survival rates similar to those of first hepatectomies. In appropriately selected patients, repeat hepatectomy for colorectal metastases is a worthwhile treatment.
