title: Hepatic resection for metastatic disease.
abstract: Hepatic resection for metastatic disease is reviewed in 30 patients (mean age 58.9 years). The primary site was the colorectum in 25; the other primary tumours were leiomyosarcoma, plasmacytoma, and adenocarcinoma (all of gastric origin), ocular melanoma and an unknown primary. Operative procedures included 7 wedge resections, 5 segmentectomies and 21 lobectomies (11 right, 4 extended right and 6 left). Major complications in seven patients included intraoperative hemorrhage in three, two of whom died, bile-duct injury in two, small-bowel infarction in one and cerebrovascular accident in one. Operative death rate was 6.7% (2 of 30). Thirteen patients were alive and free of disease a mean of 24 months after hepatic resection while 5 more were alive with disease at a mean of 36.9 months. Life-table analysis projected a 5-year survival of 50.3% for those with colorectal primaries, with no apparent difference in survival between patients with single (55.0%) and multiple (54.0%) metastases. Improved survival was projected for patients with metachronous (66.6%) versus synchronous (45.0%) tumours, primary Dukes' class A or B (66.1%) versus Dukes' class C (46.0%) tumours and those having wedge resection or segmentectomy (66.6%) versus lobectomy or extended lobectomy (48.0%). Hepatic resection for metastatic disease can be done with acceptable morbidity and mortality and the expectation of substantially prolonged survival particularly in patients with metachronous lesions or Dukes's A or B colorectal primary lesions.
