Gradient-weighted Class Activation Mapping. Row 1 shows the CT images from response (CR + PR) and no-response patients (SD + PD) before CCRT. Row 2 shows the CT images from response (CR + PR) and no-response patients (SD + PD) after CCRT. In row 3, Grad-CAM images highlight darker red areas, indicating the regions with the most contribution to maximizing the outputs of the final prediction layer. The red color represents a high predictive score of response, whereas the blue color indicates a low predictive score of response, signifying no response. CCRT, concurrent chemoradiotherapy; CR, complete response; CT, computed tomography; Grad-CAM, Gradient-weighted Class Activation Mapping; PD, progressive disease; PR, partial response; SD, stable disease
