The description of 16/1 visible lymph node cancer metastasis is wrong, it could be 1/16, indicating that one of the 16 lymph nodes taken by surgery had cancer metastasis. Lymphatic metastasis is one of the pathways of cancer metastasis, which usually occurs first with infiltration of lymph nodes around the organs, and then with metastasis of distant lymph nodes. Pathologic findings that describe the number of metastases in the lymph nodes. Generally, the first value represents the number of lymph node metastases, and the second value represents the total number of lymph nodes, with a higher ratio representing a higher number of lymph node metastases. The number and location of lymph node metastases are also used as one of the bases for cancer staging, which helps guide the treatment after surgery. Cancer metastasis also needs to be combined with the size of the primary tumor lesion to determine the exact stage and guide further treatment.
