Predictive risk score effectively detects lymphovascular invasion in rectal cancer

A predictive risk score (PRS) for lymphovascular invasion (LVI) in rectal cancer has been successfully developed, highlighting key independent predictors. Out of 55,178 patients analyzed, LVI was present in 18.9%. The PRS demonstrated an incidence of LVI of 16.3% in the low-risk group, rising to 40.5% in the high-risk group, indicating its strong predictive capabilities. The PRS achieved an accuracy of 82.4% and specificity of 97.9%, providing valuable insights for clinical decision-making.
