Whether lymphatic metastasis, which generally refers to lymph node metastatic cancer, can be cured is related to the specific site and type of malignant tumor. Generally speaking, when pure lymph node metastatic cancer with no distant metastasis, after active treatment, the prognosis of most malignant tumor patients is good, and clinical cure can be achieved. Even for the same pathological type of tumor, whether it can be cured or not is also closely related to the staging of the tumor. In the most commonly used TNM staging system, the presence of metastasis in lymph nodes is only the N (regional lymphoma) in the TNM staging of tumors, and the specific stage to which the patient belongs depends on the primary tumor (T) and distant metastasis (M). Therefore, based on the available information, it is not possible to uniformly assess whether the patient can be cured or not. However, patients and their families are still advised not to be nervous, and if the metastasis is only pure lymph node metastasis, there is usually a chance to achieve clinical cure after active treatment.
