Prognostic indicators in 67 patients with unresectable colorectal liver metastases were analyzed. These patients were identified to have isolated hepatic metastases after extensive radiological evaluation and demonstrated good performance status without evidence of liver failure. Univariate analysis revealed 6 of 22 factors that were associated with survival: alkaline phosphatase (AP), lactic dehydrogenase (LDH), occult intra‐ab‐dominal extrahepatic disease, percent hepatic replacement by tumor (PHR), sex, and carcinoembryonic antigen (CEA). A multivariate analysis identified two independent factors that jointly influenced survival: AP and PHR. Patients with an AP >175 U/liter had a greater than threefold relative risk of dying compared with patients with AP ⩾ 175 U/liter ( P = 0.0001). Patients with PHR II or III (25–75%, >75%) also had a greater than threefold relative risk of dying compared with patients with PHR 1 (<25%; P = 0.0074). Our patient population is typical of that being entered into trials examining experimental therapies. Alkaline phosphatase and extent of liver involvement by tumor are significant prognostic indicators that should be accounted for in such studies.
