Radiomics of MRI for pretreatment prediction of pathologic complete response, tumor regression grade, and neoadjuvant rectal score in patients with locally advanced rectal cancer undergoing neoadjuvant chemoradiation: an international multicenter study

ConclusionRadiomics of pretreatment MRIs can predict pCR, TRG, and NAR score in patients with LARC undergoing neoadjuvant treatment and TME with moderate accuracy despite extremely heterogenous image data. Both the tumor and MC contain important prognostic information.Key Points• Machine learning of rectal cancer on images from the pretreatment MRI can predict important patient outcomes with moderate accuracy.• The tumor and the tissue around it both contain important prognostic information.
