Results of resection and proposed guidelines for patient selection in instances of non-colorectal hepatic metastases

Resection of hepatic metastases from carcinomas of the colon and rectum appears to extend the survival time in appropriately selected patients. Selection criteria have been widely published. Similar data for patients with hepatic metastases from primary sites other than the colon and rectum are lacking. To determine which, if any, patients in the latter category benefit from resections, we reviewed ten such instances treated at our institution plus 141 instances of resection for noncolorectal hepatic metastases previously reported. The over-all five year survival rate after resection of noncolorectal hepatic metastases is 20 per cent. When Wilms' tumor is excluded, the five year survival rate is 15 per cent. Approximately four of ten patients with metastases to the liver from Wilms' tumor or carcinoid survived five years after resection. Similar benefit is rarely obtained after resection of hepatic metastases of the breast, kidney, adrenal gland and carcinomas of the stomach; malignant melanoma, and leiomyosarcoma. No extension of survival is apparent for resection of hepatic metastases of gynecologic malignancies or carcinoma of the pancreas. Specific guidelines for selection are discussed in view of the limited prognosis when tumors other than carcinomas of the colon and rectum metastasize to the liver. Careful patient selection and minimization of complications are required.
