Resection of primary solid hepatic tumors.

Experience with surgical management of 60 solid hepatic tumors was analyzed with respect to the size and type of lesion, extent of resection, operative risk, postoperative complications and survival after resection. The present study concerns 46 primary hepatic malignancies and 14 benign lesions. Lesions varied in size from 5 to 29 cm (average 13). The extent of resection required for removal was related to both the size and location of lesions. Twelve trisegmentectomies, 33 hemihepatectomies and 15 major segmentectomies were done. There were three postoperative hospital deaths, two of which were related to extensions of tumor that precluded safe resection. Postoperative complications necessitated hospital convalescence for more than 21 days in 9 of the 57 surviving patients; the hospital stay of the remaining patients averaged 12 days. The 10, 5 and 3 year survival rates of patients who had resection of malignant lesions were 33, 36 and 65 percent, respectively. We conclude that aggressive treatment of primary hepatic malignancy is justified by acceptable operative risk and significant palliation or improved survival.
