Treatment options for lung adenocarcinoma include surgery, chemotherapy, radiotherapy, targeted therapy, immunotherapy, and palliative care. The treatment of lung adenocarcinoma is generally preferred to surgery as long as the patient still has the chance to have surgery. Radical treatment can be performed through minimally invasive thoracoscopic surgery. If the stage of lung adenocarcinoma is late and cannot be operated, it needs to be treated by chemotherapy, radiotherapy, targeted drug therapy and immunotherapy. Commonly used chemotherapy drugs include paclitaxel albumin and cisplatin. Targeted drugs include gefitinib, ectinib hydrochloride and so on. If the tumor can be reduced after aggressive chemotherapy or targeted drug treatment, surgery can be considered. The so-called palliative treatment means that the tumor cannot be cured, and symptomatic treatment can be taken or chemotherapy, radiotherapy, or other local treatments can be taken. For patients with lung adenocarcinoma, they should actively go to regular hospitals to receive treatment and take targeted treatment measures under the guidance of professional doctors.
