Flowchart of conventional and software-assisted tumor bed evaluation methods. a Take the regular color image and an X-ray image of the largest residual tumor bed and record the cutting positions. b conventional evaluation method: Draw the edge of the tumor under the microscope, manually stack splice the pathological slides according to the cutting record, and assess the tumor bed. c software-assisted evaluation method: Scan H&E slides to generate WSI images, and then import them into WSI Stitcher for stitching. The software has built-in length and area measurement functions. The percentage of residual tumor cells in the tumor bed and the percentage of carcinoma in situ will be automatically calculated and displayed in the upper left corner once the labeling is completed
