The expression of SELENOP was not statistically significant concerning patient age (p > 0.05); however, differences in histological grade, lymph node metastasis, LAG-3, CD244, estrogen receptors, progesterone receptors, and Her-2 expression were statistically significant (p < 0.05) (Table 1). This evidence concerns the gene PGR and metastatic malignant neoplasm in the lymph nodes.
