摘要

背景与目的：结直肠癌（colorectal cancer，CRC）严重影响患者生存。探讨肿瘤微环境（tumor microenvironment，TME）T细胞亚群在CRC和腺瘤中的表达及意义。方法：用免疫组织化学法和流式细胞术对51例健康人（对照组）、46例结直肠腺瘤（腺瘤组）、100例CRC（癌症组）和15例CRC术后（癌术后组）患者进行T细胞亚群检测。结果：① 对照组、腺瘤组及癌症组3组中CD4

T细胞的阳性率分别是90.00%、43.75%及32.65%，CD8

T淋巴细胞的阳性率分别是30.00%、56.25%及75.51%，CD28

T淋巴细胞的阳性率分别是42.86%、30.00%及20.00%。② 对照组、腺瘤组及癌症组3组中CD4

Abstract

Background and purp

ose: Colorectal cancer (CRC) is a disease that seriously affects the quality of life. This study aimed to investigate the subsets and significance of tumor cell microenvironment T cell in CRC and adenoma. Methods: Immunohistochemistry and flow cytometry were used to test T lymphocyte subsets in 51 healthy subjects (control group)

46 patients with colorectal adenomas (adenoma group)

100 CRC patients (cancer group)

and 15 postoperative patients with CRC (postoperative group). Results: The positive rates of CD4

T cells in the control group

adenoma group and cancer group were 90.00%

43.75% and 32.65%

respectively. The positive rates of CD8

T lymphocytes were 30.00%

56.25% and 75.51%

respectively. The positive rates of CD28

T lymphocytes were 42.86%

30.00% and 20.00%

respectively. The levels of CD4

CD28

in the subgroup of colorectal tumor microenvironment showed a declining trend

while CD8

showed an increasing trend. Moreover

these trends gradually appeared in precancerous adenomas. After CRC patients underwent tumor resection

their T cell subsets recovered. Therefore

to some extent

the changes of T cell subsets in CRC can predict the development of colorectal disease early.
