The parameters associated with the DSS of patients with breast cancer included lymphovascular invasion, perineural invasion, T stage, lymph node metastasis, distant metastasis, PR status and all inflammatory markers (i.e., NLR, dNLR, PLR and LMR, all P<0.05) (Table 2) (Fig 1). Here, PGR is linked to metastatic malignant neoplasm in the lymph nodes.
