The urinary concentrations of estradiol and estrone (parent estrogens) and their estrogen metabolites had been compared in pre- or postmenopausal individuals with breast cancer and breast fibroadenoma, respectively, and are presented in Tables two and three. In postmenopausal sufferers (Table 3), the urinary levels of 2-OHE1 (P = 0.029), 2-OHE2 (P = 0.006), 4-OHE2 (P 0.001), 4-methoxyestrone (4-MeOE1) (P 0.001), and 16-OHE1 (P 0.001) in patients with breast cancer had been remarkably reduced compared with breast fibroadenoma counterparts. In premenopausal sufferers (Table 2), there was a important difference inside the urinary degree of 2-OHE2 (P = 0.022) among the two groups. In the logistic regression analysis (Fig. 1), we located that 4-OHE2 and 4-MeOE1 had been independent predictors for breast cancer danger. Individuals with 0.085 ng/mg urinary 4-OHE2 and 0.115 ng/mg urinary 4-MetOE1 had a 9.9 and 8.5 reduced risk of developing breast cancer, respectively, compared with their counterparts. ROC evaluation revealed that the levels of urinary 2-OHE1, 2-OHE2, 4-OHE2, 4-MetOE1, and 16-OHE1 in postmenopausal patients (Fig. two) had predictive value for breast cancer, using the optimal cutoffs of 0.425, 0.415, 0.085, 0.115, and 0.345, respectively.1.000 63.9 66.7 63.9 66.7 64.2 63.6 44 three 43 4 43 four 36.1 33.three 36.1 33.3 35.8 36.1.000 1.Circumstances, invasive breast cancer; Controls, breast fibroadenoma; HR, hormone receptor; Luminal A BC, hormone receptor good (ER and/or PR good), HER2 damaging, and Ki-67 low; Luminal B BC, hormone receptor constructive (ER and/or PR good), and either HER2 good or HER2 negative with higher levels of Ki-67; HER2-enriched, hormone receptor unfavorable (ER and PR adverse) and HER2 positive; TNBC, triple-negative breast cancer.
