Clinical characteristics and management of immune checkpoint inhibitor-related pneumonitis: A single-institution retrospective study.

The clinical and imaging manifestations of CIP are various, and differential diagnosis of exclusion is essential. GCS at 1-2 mg/kg is feasible to treat CIP, but the duration of GCS ≥30 mg/day should be used with caution, given the high risk of acquired infections. Re-challenges of ICI are feasible, but the recurrence of CIP needs to be closely monitored.
