Patterns of immunotherapy-induced pneumonitis in patients with non‑small‑cell lung cancer: A case series
Picard, S., Goh, D., Tan, A., Sikotra, N., Gabbay, E., & Clay, T. (2021). Patterns of immunotherapy-induced pneumonitis in patients with non‑small‑cell lung cancer: A case series. Journal of Medical Case Reports, 15 (1).
Background: Immunotherapy has become an efcacious option in the management of solid organ malignancies. Immune-related adverse events including pneumonitis are well described and may be particularly of concern in patients receiving immunotherapy for non-small-cell lung cancer.
Case presentations: In this paper, we describe three cases of immunotherapy-induced pneumonitis occurring in the management of lung malignancy. Our cases include a 54-year-old Caucasian woman with squamous cell lung cancer who was successfully rechallenged with immunotherapy after prior significant pneumonitis, a 65-year-old Caucasian man with metastatic squamous cell lung cancer who developed pneumonitis after multiple cycles of uneventful immunotherapy, and a 73-year-old Caucasian man with squamous cell lung cancer who developed earlyonset pneumonitis with rebound on steroid taper.
Conclusions: This case series has provided further insight into the presentation and risk factors for pneumonitis in patients with non-small-cell lung cancer. Each of the cases of immunotherapy-induced pneumonitis illustrates the different potential patterns that may arise when immunotherapy-induced pneumonitis develops. This case series provides key learning points that may assist physicians managing non-small-cell lung cancer with immunotherapy.
