Results of extensive surgery for liver metastases in colorectal carcinoma

Hepatic resections were performed during the past 13 years on 31 patients with hepatic metastases from colorectal carcinoma. Of the 31 patients, 22 underwent lymph node dissection of the hepatic hilus. Ten patients underwent removal of recurrent lesions in the liver, lung, adrenal gland and brain after initial hepatic resection. The overall 5-year survival rate was 45 per cent. The outcome for six patients who underwent repeat hepatectomy after an initial hepatectomy was significantly better than for nine patients with unresectable recurrence (P less than 0.01). Six of the 22 patients who underwent lymph node dissection had nodes positive for tumour. Two of the six patients underwent repeat hepatectomy and are alive after 49 and 66 months. Three- and 4-year survival rates of patients with positive lymph nodes were both 40 per cent. Repeat hepatectomy and dissection of hilar lymph nodes improves prognosis in selected patients with hepatic metastases of colorectal cancer.
