There were no statistically significant differences in OS based on menopausal status, age, breast laterality, tumor category (Tcat), Ki-67 index, progesterone receptor (PR) status, estrogen receptor (ER) status, vascular invasion (VI), perineural invasion (PI), lymphatic invasion (LI), adjuvant radiotherapy (ADJ-RT), adjuvant endocrine therapy (ADJ-ET), or the presence of neuropathy (all p > 0.05). This evidence concerns the gene MKI67 and neuropathy.
