Expression of IL-17 in CRC patients.
| Sample type | Sample size | Findings | References |
| Serum and tissue | 74 CRC tissues and paired normal mucosa, 61 CRC serum samples, and 78 healthy controls | No significant difference is observed. | [59] |
| Serum and tissue | 59 CRC tissues, 40 CRC serum samples, and 37 healthy controls | IL-17 acts as a valuable tumor marker in CRC patients. | [56] |
| Tissue | 12 CRC patients | Hypoxia induce the expression of IL-17 in Foxp3+ Tregs, which drive cancer cells to be cancer-initiating cells. | [51] |
| Tissue | 125 CRC tissues and 3 normal tissues | IL-17 gene expression level is higher in tumor tissues compared to normal mucosa. | [60] |
| Tissue | 52 CRC patients | IL-17 expression is negatively correlated with OS of CRC patients. | [52] |
| Tissue | 22 CRC patients | Tumor-infiltrating Foxp3+ IL-17+ T cells suppress tumor-specificCD8+T cells response via IL-17. | [49] |
| Serum and tissue | 9 ulcerative colitis-associated CRC tissues | IL-17+ Foxp3+ CD4+ T cells are selectively accumulated in the colitis-associated CRC niche. | [61] |
| Tissue | 50 colorectal adenomas tissues, 50 CRC tissues, and 15 healthy controls | IL-17 level is associated with the severity of dysplastic degree. | [58] |
| Tissue | 23 CRC patients | Tumor-infiltrating TH17 cells and Bv8-expressing neutrophils are associated with poor outcome in CRC. | [50] |
