Sixty‐four patients with liver metastases from colorectal cancer were studied to clarify the characteristics of the regional spread of liver metastases (secondary invasive factors) and the effects of major anatomical hepatic resection with lymph node dissection on reducing liver recurrence. No secondary invasive factors, i.e., lymph node metastasis, portal or hepatic vein involvement, bile duct involvement, micrometastasis, and direct invasion, were observed in patients with liver metastases less than 3 cm in diameter (5‐year survival rate; 100%). Secondary invasive factors were seen in 19.2% of the patients with liver metastases from 3 cm to less than 6 cm (5‐year survival rate; 28.7%), and in 45.2% of those with liver metastases 6 cm and over (5‐year survival rate; 14.6%). Secondary invasive factors were noted in 45% of the patients with recurrence in the remmant liver. Although 31% of all 64 patients exhibited secondary invasive factors, major anatomical hepatic resection with lymph node dissection achieved a low liver recurrence rate of 31.3%. In conclusion, considering the risks attributed to secondary invasive factors, major anatomical hepatic resection with lymph node dissection is an appropriate surgical procedure for patients with liver metastases exceeding 3 cm in diameter.
