Prognostic Implications of MRI-Detected EMVI and Tumor Deposits and Their Response to Neoadjuvant Therapy in cT3 and cT4 Rectal Cancer

The prevalence of mrEMVI and TDs in cT3-4 rectal cancer is high and is associated with worsened oncologic outcomes. mrEMVI regression (mr-vTRG 1-2), which occured in 25% of the cases, leads to oncologic outcomes similar to those in patients without mrEMVI on baseline MRI.
