IL17A and neoplasm: We found that high level of IL-17A was significantly positively correlated with advanced TNM stage (III + IV) (OR = 1.55, 95% CI 1.09 to 2.19, P = 0.014), but not with primary tumor (T) (OR = 1.09, 95% CI 0.56 to 2.14, P = 0.796), lymph node status (N) (OR = 1.27, 95% CI 0.77 to 2.10, P = 0.348), or tumor differentiation (OR = 1.02, 95% CI 0.68 to 1.47, P = 1.53) of patients (Figure 5).
