A study indicated a positive correlation between elevated Ki-67 expression and tumor diameter, lymph node metastasis (LNM), and blood flow grading (17), aligning with our results; another investigation revealed that Ki-67 expression was positively correlated with TNM staging and LNM, while negatively correlated with tissue grading and ER/PR expression (18). Here, MKI67 is linked to metastatic malignant neoplasm in the lymph nodes.
