The HUMT-KO group exhibited improved lymph node metastasis-free survival (LNMFS) compared with the controls (Fig. 1g), a lower rate of lymph node metastasis, and smaller metastatic lymph node volume (Fig. 1h, i), indicating that HUMT promoted lymph node metastasis in TNBC. Here, LINC00857 is linked to metastatic malignant neoplasm in the lymph nodes.
