Can preoperative CT scan predict pT and pN stages for localized MSI Colorectal Cancers

Angelo Pirozzi, Research Fellow at Mayo Clinic, shared on X:

“Ability of preop CTscan to predict pT and pN stages is limited for localized MSI Colorectal Cancers.

• 113 patients
• pT4 sensitivity 33.3%, specificity 94.0%, PPV 66.7%, NPV 79.6%
• pN+ sensitivity 70.3%, specificity 59.2%, PPV 45.6%, NPV 80.4%
