The factors related to residual liver recurrence following hepatectomy were investigated in 26 patients with hepatic metastsis from colorectal cancer. Although there is no significant difference between males and females, the frequency of residual liver recurrence was lower in patients over 61 years old than in younger patients. In rectal cancer, residual liver recurrence was higher than colon cancer recurrence but the size of the lesion, the number of foci and histological differentiation had no significant relationship with the recurrence. No marked difference was seen between synchronous and metachronous metastasis. The timing of the operation did not influence the prognosis and was the same for simultaneous and metachronous resection. Residual liver recurrence was seen in 4 of 7 patients (57.1%) who underwent partial resection but in 19 patients who underwent wide resection it was seen in only 4 (21.1%), which indicates that wide resection is important and should be the operation of choice in the case of metastatic liver cancer.
