The therapeutic drugs for lymphatic metastasis of lung tumor include chemotherapeutic drugs such as etoposide, paclitaxel, docetaxel, gemcitabine and platinum; targeted therapeutic drugs such as gefitinib, ectinib and ositinib; and immunotherapeutic drugs such as karelizumab, sindilizumab and enviromilizumab. Lymphatic metastasis of lung tumor is mostly seen in the middle stage of lung cancer, when most patients miss the time of surgical treatment and need to take radiotherapy, chemotherapy, targeted therapy and immunotherapy for comprehensive treatment. Different pathological types of tumors and physical conditions are different, so the treatment plans and drugs used will be different, and patients need to follow the doctor’s instruction to carry out standardized treatment.
