From: Density of CD4(+) and CD8(+) T lymphocytes in biopsy samples can be a predictor of pathological response to chemoradiotherapy (CRT) for rectal cancer

Figure 2

Density of CD4(+) and CD8(+) T cells and ratio of tumor reduction and histological response to CRT. The density of immunoreactive T cells was determined in three different biopsy samples, and mean value was calculated in each case. The longitudinal length of the rectal tumor was measured by barium enema study before and after CRT, and the ratio of tumor reduction was calculated. Histological response grade was evaluated by pathologists according to the definitions in the Japanese Classification of Colorectal Carcinoma.
