Surgical resection of colorectal carcinoma metastases to the liver: A prognostic scoring system to improve case selection, based on 1568 patients

The comparison between expected survival and estimated operative risk can help determine on an objective basis whether surgery is worthwhile. This system needs further prospective validation.
