Prospective Correlation of Magnetic Resonance Tumor Regression Grade With Pathologic Outcomes in Total Neoadjuvant Therapy for Rectal Adenocarcinoma
Tumor regression grade defined as the ratio between fibrosis and residual tumor, is routinely used to assess response to therapy and demonstrated to be an important predictor of patient’s outcome. In the era of TNT (total Neoadjuvant Therapy) this will help assess response to avoid surgery. It will be nice to add MRD testing in the blood as another tool.
