A nomogram predicting disease‐free survival in patients with colorectal liver metastases treated with hepatic resection: multicenter data collection as a Project Study for Hepatic Surgery of the Japanese Society of Hepato‐Biliary‐Pancreatic Surgery

This nomogram can easily calculate the median and yearly disease-free survival rates from only 6 preoperative variables. This is a very useful tool to determine the likelihood of early recurrence and the necessity for perioperative chemotherapy in patients with colorectal liver metastases after hepatic resection.
