The Prognostic Value of the Expression of SMC4 mRNA in Breast Cancer

AIM: To investigate the mRNA expression and clinical significance of structural maintenance of chromosomes protein 4 (SMC4) in breast cancer.

Sumario:AIM: To investigate the mRNA expression and clinical significance of structural maintenance of chromosomes protein 4 (SMC4) in breast cancer. METHODS: A total of 23 paired samples were sequenced, and data from the Cancer Genome Atlas were analyzed. RESULTS: SMC4 mRNA level was significantly upregulated in breast cancer tissues (P < 0.001). Patients with high mRNA expression of SMC4 had significantly poor survival (P = 0.012). Subgroup analyses show that in nontriple negative breast cancer (non-TNBC) patients, the high SMC4 mRNA expression, older age (>65), negative progesterone receptor, and advanced stages (III-IV) were independent risk factors (HR = 3.293, 95% CI 1.257-8.625, P = 0.015). In patients with TNBC, high mRNA expression of SMC4 correlated with better survival rate (P < 0.046). CONCLUSION: SMC4 mRNA level is a good prognostic biomarker for patients with breast cancer.
