Adipocyte related peptides - galanin and resistin in endometrioid type endometrium cancer

The aim of (this) study was to investigate concentrations of galanin and resistin in patients with endometrioid type endometrium cancer.

A total of 85 patients (52 Endometrioid type Endometrium Cancer patients and 33 healthy controls) were included in the study. Serum galanin and resistin levels were measured by an enzyme-linked immunosorbent assay (ELISA).

It was found that the sensitivity and specificity of galanin at the cut off level of 0,37 ng/mL, was 82.96% and 68.78% respectively (AUC = 0.795, CI:0.691-0.898, p < 0.001). Sensitivity and specificity of resistin at the 0.27 ng/mL cut off level, was found to be 82.95% and 59.12% respectively (AUC = 0.705, CI:0.588-0.822, p < 0.001) for prediction of endometrioid type endometrium cancer diagnosis. Bivariate logistic regression analysis showed that, increased galanin concentration, greater than 0.37 ng/mL, increased the risk of having endometrioid type endometrium cancer 10.2 times (95% CI: 3.425-30.881, p < 0.001) and resistin concentration > 0.27 ng/mL, increased the risk of having endometrioid type endometrium cancer 5.6 fold (95% CI: 1.939-16.282, p = 0.001). On the other hand, according to adjusted Odds Ratio results of the multiple logistic regression analysis, effect of interaction between galanin and resistin on having endometrioid type endometrium cancer was statistically significant. Increased galanin concentration > 0.37 ng/mL with increased resistin concentration > 0.27 ng/mL had adjusted Odds Ratio = 27.182 times greater risk of having endometrioid type endometrium cancer (95% CI: 6.653 to 111.109, p < 0.001).

Increased galanin and resistin levels, either separately or together with, seemed to increase the risk of endometrioid type endometrium cancer other than different risk factors.
