A Study on Exploring the Abscopal Effect Induced by Different Radioimmunotherapy Combination Patterns in the Treatment of Non-Small Cell Lung Cancer With Multiple Metastases

Summary

It is planned to carry out a multicenter umbrella study to find the optimal organ combination and the best radioimmunotherapy combination pattern, so as to improve the survival of NSCLC patients with multiple metastases. At the same time, by using multimodal omics data, machine learning will be employed to construct a prediction model for the abscopal effect, and explore the immunoregulation of organ-specific radiotherapy and biomarkers of the abscopal effect. The main objective is to find the optimal organ combination and the best radioimmunotherapy combination pattern.

Conditions

• NSCLC Stage IV Without EGFR/ALK Mutation

Interventions

DRUG

chemotherapy + PD-1 inhibitors

The patient receives 4 cycles of treatment with "chemotherapy + PD-1 inhibitors". If there is no disease progression, the patient will receive radiotherapy (radiation dose: 5-8Gy \* 3-10 fractions) for pulmonary lesions, lymph node lesions and visceral lesions in combination with the PD-1 inhibitors . During the follow-up, the PD-1 inhibitors will be maintained until the disease progresses or the toxicity is intolerable. The maximum duration of immunotherapy shall not exceed 2 years.

During the follow-up, the PD-1 inhibitors will be continued until the disease progresses or the toxicity becomes intolerable. The maximum duration of immunotherapy shall not exceed 2 years.
