Analysis of hepatic recurrence of colorectal cancer after resection of hepatic metastases

Abstract

Forty patients with history of resected hepatic metastases of colorectal cancer were examined for pattern of recurrence. The 5-year survival rate was 41.3% for 40 patients. Recurrences of the malignancy were seen in 25 of the patients, with hepatic recurrence in 42.5% of them. The hepatic recurrence rate did not correlate with the lobar distribution of metastases or surgical methods. The pathological margins of less than 1 cm, 3 or more liver metastatic lesions, and the metastatic lesions of greater than 5 cm were at increased risk of hepatic recurrence. The recurrence rate was high, or 56% for aneuploid tumors, while it was 18.5% for diploid tumors.
