The expression of PKMYT1 was not statistically significant concerning patient age, and lymph node metastasis (p > 0.05); however, differences in histological grade, LAG-3, CD244, estrogen receptors, progesterone receptors, and Her-2 expression were statistically significant (p < 0.05) (Table 1). The gene discussed is ESR1; the disease is metastatic malignant neoplasm in the lymph nodes.
