侵袭转移是恶性肿瘤最为重要的生物学特征之一，其中，淋巴结转移是其重要的

Invasion and metastasis is one of the most important biological characteristics of malignant tumors. Among them, lymph node metastasis is its important metastatic route. The number of lymph node metastases, that is, the number of positive lymph nodes is a reliable indicator of the ability of malignant tumors to invade and metastasize, and it is also important for the stage of malignant tumors index. TNM staging is one of the most widely accepted staging schemes for evaluating the progression of malignant tumors in advanced stages. The number of positive lymph nodes is an important parameter for TNM staging. Therefore, in the clinicopathological diagnosis, it is of great clinical value to detect whether the malignant tumor lymph node metastasis occurs in the lymphatic drainage area around the tumor after surgical removal of the specimen, and to determine the number of positive lymph nodes. However, in clinical medical practice, due to many subjective and objective factors, it is often the case that the number of detected lymph nodes is insufficient, which not only directly affects the accuracy of TNM staging, but also seriously affects the accurate assessment of the ability of invasion and metastasis of malignant tumors. Therefore, exploring new parameters that can be used to evaluate the ability of malignant tumor invasion and metastasis and lymph node metastasis has important clinical value.

Invasive metastasis is one of the most important biological features of malignant tumors, among which lymph node metastasis is an important way of metastasis, and the number of lymph node metastasis, or the number of positive lymph nodes, is a reliable index to reflect the ability of malignant tumor invasion and metastasis, and also an important index of malignant tumor course stage. TNM staging is one of the most widely recognized stage sepsis programs for evaluating the progression of malignant tumors in the progressive period, and the number of positive lymph nodes is an important parameter of TNM staging. Therefore, in clinical pathology diagnosis, it is of great clinical value to detect whether malignant tumor lymph node metastasis occurs in the lymphatic drainage area around the tumor of surgically removed specimens, and to determine the number of positive lymph nodes. However, in clinical practice, due to many main objective factors, there are often insufficient detection of lymph nodes, which will not only directly affect the accuracy of TNM staging, but also seriously affect the accurate assessment of the invasive metastasis of malignant tumors. Therefore, it is of great clinical value to explore new parameters that can be used to evaluate the ability of malignant tumor invasive metastasis and lymph node metastasis.

The number of lymph node metastasis, that is, the number of positive lymph nodes, is a reliable indicator of the ability of invasion and metastasis of malignant tumors, and also an important indicator of the course and stage of malignant tumors. TNM staging is one of the most widely accepted methods to evaluate the progression of advanced cancer. The number of positive lymph nodes is an important parameter of TNM staging. Therefore, in the clinical pathological diagnosis, it is of great clinical value to detect whether the lymph node metastasis occurs in the drainage area around the tumor of the resected specimen and determine the number of positive lymph nodes. However, in clinical practice, due to many subjective and objective factors, the number of detected lymph nodes is often insufficient, which will not only directly affect the accuracy of TNM staging, but also seriously affect the accurate assessment of the invasion and metastasis of malignant tumors. Therefore, it is of great clinical value to explore new parameters that can be used to evaluate the ability of invasion and metastasis of malignant tumors and lymph nodes.<br>
