Corresponding CD3+ and CD8+TIL densities in biopsy and surgically resected specimens for all cases. A. Alterations in the CD3+ and CD8+TILs during radiotherapy (RT); B. Alterations in the CD3+ and CD8+TILs during chemotherapy (CT); C. Alterations in the CD3+ and CD8+TILs during chemoradiotherapy (CRT). CD3+ and CD8+ were significantly enhanced during neoadjuvant treatments in all cases. Unpaired t-tests revealed that there were no significant differences between each two of these three groups.
