Single-cell Sequencing of BLF to Guide the Treatment of Radiation Pneumonitis or Immune Checkpoint Inhibitor Pneumonitis

Single-cell Sequencing of Bronchoalveolar Lavage Fluid to Guide the Treatment of Radiation Pneumonitis or Immune Checkpoint Inhibitor Pneumonitis

Sponsor

Xinqiao Hospital of Chongqing

Enrollment

40 participants

Start Date

Aug 1, 2023

Study Type

INTERVENTIONAL

Conditions

Pneumonitis

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.
