Surgical Margin Prediction by Surgeons in Colorectal Liver Metastases: Inaccuracy Revealed

Surgeons’ ability to accurately predict surgical margins following resection of colorectal liver metastases (CRLM) was evaluated in this study. The analysis included 190 preoperative and 190 postoperative assessments from 95 cases, comparing surgeon assessments to histopathologic assessment. Results showed that surgeons are inaccurate at predicting positive and close surgical margins, with low sensitivity and positive predictive values. Therefore, a predicted close margin should not necessarily deter surgeons from considering resection of CRLM.
