Metastasis to lymph nodes in neck one and a half years after lung cancer surgery is still serious, which requires timely local and systemic anti-cancer treatment. Metastasis to lymph nodes in the neck one and a half years after lung cancer surgery indicates that the patient’s condition has progressed to intermediate or advanced stage, and it is recommended to improve CT, MRI and other examinations in time to see whether there are metastases to distal organs. If only neck lymph node metastasis occurs, the situation is not very serious, but if accompanied by distal organ metastasis, the condition is more serious. In case of neck lymph node metastasis of lung cancer, it is difficult to perform surgery for resection, and while systemic chemotherapy is carried out, local radiotherapy is also needed for the metastatic lesions, which can help prolong the survival cycle of patients.
