In the high TIL group, 65.3% of cases were classified as high-grade tumors (low TIL group: 22.1%, P < 0.05), and the Ki-67 index (45.2 ± 12.3% vs 25.6 ± 10.8%), positive rate of vascular emboli (38.9% vs 12.4%), and lymph node metastasis (LNM) rate (52.6% vs 28.4%) were all significantly higher. Here, MKI67 is linked to metastatic malignant neoplasm in the lymph nodes.
