These 8 genes, associated with the prognosis of BC, are considered to be the best features, and included apolipoprotein D (APOD), Chemokine (C-X-C motif) ligand 14 (CXCL14), Interleukin-33 (IL33), leukemia inhibitory factor receptor (LIFR), nuclear factor kappa B inhibitor zeta (NFKBIZ), tachykinin-1 receptor (TACR1), nerve growth factor receptor (NGFR), and thymic stromal lymphopoietin genes (TSLP). Here, APOD is linked to breast cancer.
