Surgical treatment for extrahepatic recurrence after hepatectomy for colorectal metastases.
OBJECTIVE
Recurrence of the remnant liver or extrahepatic sites after hepatic resection for colorectal metastases is concerned as a significant prognostic factor. While regional chemotherapy may reduce recurrence of the liver, appropriate therapy for extrahepatic metastases needs to be elucidated.


METHODS
We identified 207 patients undergoing hepatectomy for colorectal metastases. Patient characteristics, clinicopathological features, sites of extrahepatic recurrence, and outcome are examined.


RESULTS
Recurrence of the lung, brain, bone, and other site after hepatic resection was seen in 49, 8, 8, and 12 cases, respectively. Fourteen patients underwent pulmonary resection, and three patients are alive and disease-free survival was 35, 79, and 128 months after the second resection. Overall 2- and 5-year survival was 64 and 18%. Univariate and multivariate analysis indicated that time and number of pulmonary metastases, and serum CEA levels are independent prognostic factors. Surgical resection for brain metastasis was only in one case who survived for 31 months. Other treatment such as gamma-knife may not improve outcome.


CONCLUSIONS
Both hepatic and pulmonary resection for colorectal metastases could prolong survival in selected patients. Surgical indication for other extrahepatic metastases must be strictly selected, although resection of brain metastasis might lead to better outcome.
