In our own study, it was shown that the concentrations of these parameters in the urine of patients with BC were statistically significantly higher compared to the concentrations of the tested proteins in healthy subjects: HAI-1 (p ≤ 0.001), STMN-1 (p ≤ 0.001), and TN-C (p = 0.002). This evidence concerns the gene SPINT1 and breast cancer.
