An Observational Clinical Study of Stereotactic Radiotherapy for Advanced Non-Small Cell Lung Cancer With Stable Disease After PD-1 Inhibitor Treatment

An Observational Clinical Study of Increasing Stereotactic Radiotherapy in Patients With Advanced Non-small Cell Lung Cancer After Treatment With PD-1 Inhibitors And Evaluation of Stable Disease

Brief summary (registry, in English)

After the treatment of advanced non-small cell lung cancer with immune checkpoint inhibitor PD-1/PD-L1 monoclonal antibody, if the treatment response of complete response (CR) or partial response (PR) can be achieved in the early stage, the patients are expected to obtain a better long-term survival rate. Radiotherapy can synergistically improve the effect of immunotherapy. Therefore, we propose a hypothesis: in patients with advanced lung cancer, if only stable disease (SD) is achieved after PD-1 antibody immunotherapy in the early stage, by increasing the stereotactic radiotherapy (SBRT) for primary or metastatic lesions, in order to improve the mechanism of tumor antigen release, promote the activation and activation of effector T cells, and increase the sensitivity of immunotherapy, so as to achieve the goal of early improvement of objective remission rate (ORR). It is expected to improve the long-term survival rate of patients.

Other

  • The patient's compliance is poor and violates the test regulations;

Who the study is looking for

  • Informed consent has been signed, and according to the judgment of the investigator, the patient can comply with the study protocol;
