Managing Pulmonary Toxicities Associated with Immunotherapy: A Case Discussion.

Immunotherapy has changed the field of oncology around the world with the approval of immune checkpoint inhibitors for a number of tumor types over the last 5 years. However, immune-mediated adverse events can be challenging and difficult to treat, with one of the most dire consequences being immune-mediated pneumonitis. KEY POINTS: Rapid intervention and aggressive management for grade 3 or greater pneumonitisSlow taper of steroids and also recommend pneumocystis carinii pneumonia prophylaxisMonitor carefully for a pneumonitis flare with steroid taper, which can occur in the absence of resuming anti-programmed cell death protein 1 (PD-1) [1], and do not resume anti-PD-1 therapy until completely off steroids and no clinical or radiologic evidence of recurrenceConsider observation without anti-PD-1 resumption-in this case, durable response was maintained even without resuming anti-PD-1 therapy. © AlphaMed Press 2019.
