AFAP1 and metastatic malignant neoplasm in the lymph nodes: The multivariate regression analyses further exposed that large tumor size (HR=1.785, 95%CI: 1.063-2.996), advanced clinical stage (HR=2.985, 95%CI: 1.772-5.028), lymph-node metastasis (HR=2.354, 95%CI: 1.408-3.933) and high lncRNA AFAP1-AS1 level (HR=2.6, 95%CI: 1.526-4.431) were independently symbolic of TNBC patients’ unfavorable 3-year survival in this Chinese cohort (Supplementary Table 3).
