Results of the multivariate Cox regression analysis of DFS. DFS: disease-free survival; PMRT: postmastectomy radiation therapy; TNBC: triple-negative breast cancer; LVI: lymphatic vascular infiltration; ER: estrogen receptor; PR: progesterone receptor; HER-2: human epidermal growth factor receptor; TNBC: triple-negative breast cancer; pCR: pathological complete response; HR: hazard ratio; CI: confidence interval.
