Patients and Methods: Eighty-six consecutive cases with TNBC, who underwent surgery at our faculty from 2009 to 2015, were divided into two groups according to PH-BCS. Prognostic analyses for disease-free survival and overall survival between the two groups were performed. Results: The positive PH-BCS group (n=44) had a significantly better prognoses than the negative PH-BCS group (n=42) (p<0.001). No recurrent cases were observed in the positive PH-BCS group. In the negative PH-BCS group, tumor and node status and chemotherapy were indicated as significant prognostic factors, and further step-wise multivariate analysis revealed only node status as a significant prognostic factor. Conclusion: Breast cancer screening at least every 2 years may improve the prognosis of TNBC. %U https://ar.iiarjournals.org/content/anticanres/41/2/1077.full.pdf
