Lung adenocarcinoma needs radiotherapy if chemotherapy is ineffective.
First of all, chemotherapy and radiotherapy are common treatment plans for lung adenocarcinoma, and both of them can be treated independently or in combination, that is to say, even if chemotherapy for lung adenocarcinoma is ineffective, radiotherapy can be continued, and both of them do not affect each other.
In addition, the ineffectiveness of chemotherapy for lung adenocarcinoma may be caused by incorrect choice of drugs and low efficacy of single treatment, so it may be possible to get good therapeutic effect by continuing systemic and localized radiotherapy at a later stage; or you can change chemotherapy drugs under the guidance of doctors and then carry out combined treatment with radiotherapy, with the specific therapeutic plan under the guidance of doctors.
