Abstract
Objective: To investigate the degree and distribution of tissue-resident CD8 + T cell (CD103 + CD8 + T cells) infiltration in colorectal cancer (CRC) tissues, and to analyze its relationship to patients’clinicopathological features and prognosis. Methods: Tissue chips of 88 cases of colon cancer tissues (No.HColA180Su14) and 77 cases of rectal cancer tissues (No. HRec-Ade180Sur-03) were obtained from Shanghai Outdo Biotech Co., Ltd. Immunofluorescence staining was performed to examine the infiltration pattern and degree of CD103 + CD8 + T cells in the collected CRC tissues and their para-cancerous tissues. Wilcoxon rank test was used to compare CD103 + CD8 + T cell infiltration degree in CRC tissues and the para-cancerous tissues. Chi-square test was used to analyze the relationship between CD103 + CD8 + T cell infiltration in CRC and patients’clinicopathological features. Kaplan-Meier survival analysis was conducted to explore the correlation between CD103 + CD8 + T cell infiltration and patients’prognosis. Cox model was applied to analyze the correlation between different clinical parameters and patients’prognosis. Results: CD103 + CD8 + T cell infiltration presented no significant differences between CRC and para-cancer tissues (P>0.05). Patients with distant metastasis had significantly lower CD103 + CD8 + T cell infiltration rate than patients without distant metastasis (P<0.01). There was no significant correlation between the infiltration of CD103 + CD8 + T cells and other clinicopathological features (P>0.05). Kaplan-Meier survival analysis showed that the overall survival (OS) of patients with high CD103 + CD8 + T cell infiltration was significantly longer than that of the patients with low infiltration (54.42% vs 25.00%, P<0.05). Multivariate Cox model analysis indicated that pathological grade (P<0.01) and high CD103 + CD8 + T cell infiltration (P<0.05) were independent prognostic factors for CRC. Conclusion:CD103+CD8+T cell infiltration in CRC is associated with patients’prognosis, suggesting that CD103 + CD8 + T cell plays an important role in the initiation and development of CRC.
