Abstract

Expression of miR‑129-5p and miR-433 was detected in breast cancer to explore the relationship with clinicopathological features of breast cancer. Seventy-eight patients with breast cancer diagnosed in Zhengzhou Central Hospital Affiliated to Zhengzhou University (Zhengzhou, China) from February 2016 to September 2017 were collected and enrolled into the research group. Additionally, 72 healthy people who underwent physical examination during the same period were selected as the control group. The expression levels of miR-129-5p and miR-433 in peripheral blood of the two groups were detected by fluorescence quantitative PCR (RT-PCR). The relationship between the expression of miR‑129-5p, miR-433 and clinicopathological features, clinical stages of breast cancer, and the degree of differentiation were analyzed. Expression of miR-129-5p and miR-433 in the research group was significantly lower than that in the control group (P<0.05). Expression of miR-129-5p in the blood of breast cancer patients was correlated with tumor size, differentiation degree, lymph node metastasis, depth of invasion and clinical stages (P<0.05). Expression level of miR-433 was correlated with the degree of differentiation, lymph node metastasis, depth of invasion and clinical stages (P<0.05). miR-129-5p and miR-433 were positively correlated with differentiation degree (r=0.8507, r=0.7522; P<0.05), and negatively correlated with clinical stages (r=-0.6595, -0.8947; P<0.05). The sensitivity and area under curve (AUC) were higher in joint detection (87.5 and 0.95% respectively), compared with those in single detection. Patients were separated into high and low expression groups according to the median values of miR-129-5p and miR-433. The one‑year survival rate of breast cancer patients was analyzed. Patients in the low expression groups had lower survival rates than patients in the high expression groups (P<0.05). In conclusion, the expression of miR-129-5p and miR-433 in peripheral blood of breast cancer patients is lower than that of healthy people, and the expression level is closely related to clinical stages and differentiation degree, which is expected to provide reference value for judging the state of breast cancer patients. The combined detection of miR-129-5p and miR-433 is of great significance in the diagnosis and treatment of breast cancer.
