Results of 32 major hepatic resections for primary and secondary malignancies of the liver.

Thirty-two consecutive liver resections performed during the years 1972-1984 for liver malignancies have been analysed. Among indications for resection were primary liver malignancy and liver secondaries equally often in 16 patients, mostly originating from colorectal cancer (12 patients). Ultrasound (US) was the most reliable diagnostic method being fully confident in 11 patients studied. Computed tomography (CT) missed one lesion out of 13 (confidence rate 92%), whereas angiography and liver scintiscan missed two and three lesions respectively with a confidence rate of 84 and 79. Most of the patients (94%) experienced an anatomical liver resection including 12 extended right lobectomies (ERL), eight right lobectomies (RL), five left lobectomies (LL), and five left lateral segmentectomies (LLS). The hospital mortality (16%) was almost exclusively connected to the ERL procedure with a 33% mortality rate. The crude 3-year survival rate of the series was 28%. Among the patients undergoing liver resection for colorectal cancer secondaries the corresponding figure was 41%. More than half of the patients surviving surgery have died of the same malignancy mostly developing in the remaining liver.
