“…The majority of studies focused on predicting the pathological complete response, using a single MRI sequence (T2-WI or apparent diffusion coefficient (ADC) maps) or a multiparametric approach [ 49 , 50 , 51 , 52 , 53 , 54 , 55 ]. Additionally, there are several studies that investigated the performance of radiomic features to discriminate good responders [ 56 , 57 , 58 , 59 , 60 ]. In contrast to our research, these investigations either used other pathologic classifications for the quantification of tumor regression grade such as Dworak [ 57 ] or Mandard [ 59 ] or the authors divided their study population different from our approach, including in the non-responders’ group both patients with a TRG score of 2 and 3 [ 56 , 58 , 60 ].…”
