Randomized Controlled Clinical Study of Drug Therapy Combined With Thoracic Radiotherapy for Non-oligometastatic NSCLC

Study Overview
=================
Brief Summary
-----------------
To investigate whether radiotherapy combined with drug therapy is beneficial to non- oligometastatic stage IV NSCLC

Detailed Description
-----------------
Group A (targeted therapy, immunotherapy, chemotherapy); The efficacy was evaluated after the second and fourth cycles of chemotherapy and immunotherapy; The efficacy of targeted therapy was evaluated every month; Group B (drug concurrent radiotherapy group: combined with thoracic primary tumor radiotherapy on the basis of targeted therapy, immune, chemotherapy ) The efficacy was evaluated after the second and fourth cycles of chemotherapy and immunotherapy; The efficacy of targeted therapy was evaluated every month; Radiographic evaluation was performed after radiotherapy for the primary lesion of the chest.
