Figure 1

The histopathological appearance of representative cases of a complete responder and a non-responder (H&E, magnification X4). In the case of a complete responder (Figure 1A), the mucosa was eroded at the tumor site and there was marked fibrosis with focal microcalcifications. No residual tumor was found. In the case of a non-responder (Figure 1B), nearly no signs of response were noted (tumor regression grade [TRG] IV). Abundant tumor was found, with minimal fibrosis and regressive changes between the invasive tumor.
