Abstract:

Objective To investigate the expression of interleukin-6 (IL-6) and prolactin (PRL) in breast invasive ductal carcinoma (BIDC) and its clinical significance.   Method Immunohistochemistry was used to detect the expression of IL-6 and PRL in 63 cases of breast cancer and its paraneoplastic tissues and 17 cases of breast fibroadenoma. The clinical pathological parameters and event-free survival were analyzed statistically.   Results The positive rates of IL-6 and PRL in infiltrating ductal carcinoma were higher than those in adjacent tissues and fibroids (P<0.05). The expressions of IL-6 and PRL in the adjacent tissues were higher than those in paratumor tissues (P<0.05). The expression of IL-6 and PRL were correlated with tumor size and TNM stage (P<0.05). There was a significant positive correlation between IL-6 and PRL expression (rs= 0.842, P<0.05). Event-free survival showed that the event-free survival of patients with high expression of IL-6 and PRL was lower than that of patients with low expression (IL-6, Log- rank= 5.186, P= 0.023; PRL, Log- rank= 5.743, respectively. P= 0.017). The univariate Cox risk model showed that lymph node metastasis, high TNM stage, positive IL-6 expression, and positive PRL expression all had influence on the event-free survival of patients.  Conclusion The detection of PRL and IL-6 expression in breast cancer is beneficial to its prognosis diagnosis; Reducing the patient's stress, promoting emotional regulation, improving sleep quality and other factors can, to some extent, reduce the risk of breast cancer, progression and poor prognosis.
