Abstract Objective To analyze the expressions of vascular endothelial growth factor (VEGF), Hsa-miR-93, and S100 calcium binding protein A8 (S100A8) in breast cancer and their relationship with prognosis. Methods The cancer tissues and corresponding para-carcinoma nomal tissues were collected from 77 patients pathologically confirmed with new breast cancer who were treated in the Chizhou People’s Hospital from January 2017 to June 2018. The expressions of VEGF and S100A8 in tissues were detected by immunohistochemistry; the expression of Hsa-miR-93 was detected by in situ hybridization method; the relationship between VEGF, Hsa-miR-93, S100A8 levels and clinicopathological characteristics of patients were analyzed; according to patients’ survival data of three years after surgery, the effects of VEGF, HSA-miR-93, and S100A8 expression levels on prognosis and survival were analyzed. Results The positive expression rates of VEGF, Hsa-miR-93, and S100A8 in breast cancer tissues were higher than those in para-carcinoma nomal tissues (P < 0.05). The positive expression of VEGF in cancer tissues was related to lymph node metastasis (P < 0.05), while not related to age, histological grading, TNM staging or tumor diameter (P > 0.05); the positive expression of Hsa-miR-93 in cancer tissues was related to TNM staging and lymph node metastasis (P < 0.05), while not related to age, histological grading or tumor diameter (P > 0.05); the positive expression of S100A8 in cancer tissues was related to histological grading, TNM staging, and lymph node metastasis (P < 0.05), while not related to age or tumor diameter (P > 0.05). There was no significant difference in survival rate between patients with positive expression of VEGF, HSA-miR-93, and S100A8 in breast cancer tissues and patients with negative expression (P > 0.05). Conclusion VEGF, miR-93, and S100A8 are highly expressed in breast cancer tissues, but there is no significant difference in positive expression rate and survival rate.
