The Association between Leukocyte and Its Subtypes and Benign Breast Disease: The TCLSIH Cohort Study

الملخص EN

Inflammation plays a crucial role in the formation of benign breast disease.

Given the limited study to explore the association between leukocyte as an indicator of immune system and benign breast disease, we used data from a large cross-sectional study to investigate association between leukocyte and its subtypes and benign breast disease among women in the general population.

The data were derived from baseline data of the Tianjin chronic low-grade systemic inflammation and health (TCLSIH) cohort study during 2014 and 2016.

Breast thickness and nodules status were assessed by using ultrasonography.

Leukocyte and its subtype counts were carried out using the automated hematology analyzer.

Multiple logistic regression analysis was used to examine the association between leukocyte and its subtypes and prevalence of benign breast disease.

In the present study, the prevalence of benign breast disease was 20.9%.

After adjustments for potentially confounding factors, the odds ratios (95% confidence interval) for benign breast disease across lymphocyte quintiles were as follows: 1.00 (reference), 0.99 (0.82, 1.2), 0.85 (0.69, 1.04), 0.84 (0.68, 1.02), and 0.75 (0.61, 0.92) (P for trend = 0.002).

An inverse association between lymphocyte counts and benign breast disease was found, but leukocyte and other subtypes have nothing to do with benign breast disease.

Further prospective studies are needed to determine the findings.
