Of these, 39 underwent neoadjuvant treatment (chemoradiotherapy) followed by surgery, and 9 direct surgery. In 25, the PET/CT extension study revealed distant disease, leading to systemic treatment.

The volume of interest (VOI) of the primary tumor (VOI-_T) was manually segmented, then a voxel-thick VOI was added around VOI-_T to define the peritumoral area (VOI-_PT). Morphological, intensity-based, histogram and texture parameters were obtained from VOIs. The patients were divided into two groups as pCR and non-complete pathological response (npCR).
