Brief summary
A multicenter, exploratory clinical research, to map the radiation or immune checkpoint inhibitor pneumonitis in patients with alveolar lavage single-celled map. Find out the pathogenesis and prevention strategies of radiation or immune checkpoint inhibitor pneumonitis. Specific treatment is given based on the recommendation of the treatment guidelines for radiation or immune checkpoint inhibitor pneumonitis and the results of single cell sequencing, which will become a new technology for clinical application.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Response rate | 8 weeks | Tumor diameter is measured before and 8 weeks after treatment. Area alleviated by lung shadow or ground-glass changes more than 50% was significant; The alleviating area of lung shadow or ground-glass change was 20% \ 50%. Area alleviated by shadow or ground-glass changes in lung after treatment. 20% or worse than before treatment is ineffective. |
