Abstract:
Objective:To investigate the relationship between key molecules of interleukin-6/signal transducer and activator of transcription 3 (IL-6/STAT3) signaling pathway and breast cancer susceptibility.Methods:A case-control study design was adopted. 136 patients with breast cancer admitted to Department of Breast Surgery, Yantai Yantaishan Hospital from Mar. 2021 to Mar. 2023 were selected as the case group, and 136 healthy subjects of the same age were matched as the control group in a 1:1 ratio. The clinical data and key molecules of IL-6/STAT3 signaling pathway were compared between the two groups. The risk factors of breast cancer susceptibility were evaluated by conditional Logistic regression and addition analysis, and the diagnostic efficiency of receiver operating characteristic curve (ROC) and area under curve (AUC) were plotted.Results:The body mass index (BMI) (22.21±0.68 vs. 21.30±0.70 kg/m 2), age at menarche (13.50±1.24 years vs. 14.83±1.42 years), IL-6 (3.50±1.05 vs. 2.41±0.74), Janus protein kinase 1 (JAK1) mRNA (1.23±0.36 vs. 0.88±0.26), STAT3 mRNA (1.68±0.50 vs. 1.17±0.35), and menopause (30.15% vs. 55.88%), breastfeeding (82.35% vs. 92.65%), physical exercise (44.12% vs. 58.09%) were significantly different between the case group and the control group ( t=10.87, 8.23, 9.89, 9.19, 9.75, χ2=18.37, 6.59, 5.31, P<0.05). Breastfeeding [odd ratio ( OR) : 0.550], interleukin-6 (IL-6) ( OR: 4.409), janus protein kinase 1 (JAK1) ( OR: 5.370) and signal transducer and activator of transcription 3 (STAT3) ( OR: 4.386) mRNAs were risk factors for breast cancer susceptibility ( P<0.05). ROC curve showed that the combined diagnostic efficacy of IL-6, JAK1, STAT3 mRNA in breast cancer was significantly better than that of a single diagnostic efficacy. The incidence rate of breast cancer in those who were exposed to IL-6 mRNA and breast feeding was 3.508 times higher than that in those who were not exposed. The incidence rate of breast cancer in those who were exposed to JAK1 mRNA and breast feeding at the same time was 4.136 times higher than that in those who were not exposed. The incidence rate of breast cancer in those who were exposed to STAT3 mRNA and breast feeding was 3.537 times higher than that in those who were not exposed. Conclusion:The key molecules of IL-6/STAT3 signaling pathway and breast-feeding are predisposing factors of breast cancer, and they have additive interaction, thus increasing the susceptibility of breast cancer, which has significant practical significance for the differential diagnosis and treatment of this disease.
