Fig. 4From: Predictive and prognostic value of Matrix metalloproteinase (MMP) - 9 in neoadjuvant chemotherapy for triple-negative breast cancer patientsCumulative disease-free survival of non-pCR patients according to MMP-9 levels after NAC. High expression of hMMP-9 was significantly correlated with an unfavorable outcome (P < 0.001). a Disease-free survival according to histological expression of MMP-9 protein (hMMP-9); b Disease-free survival according to serum MMP-9 (sMMP-9) at baseline; c Disease-free survival according to sMMP-9 at surgery; d Disease-free survival according to sMMP-9 changeBack to article page
