Commentary
“Checkpoint inhibitors have significantly improved outcomes in multiple cancer types with historically poor prognoses including non-small cell lung cancer (NSCLC). These drugs are associated with immune-related adverse events. Drs. Boudou-Rouquette et al report a case of a 60-year old man with NSCLC who was diagnosed with diffuse large B-cell lymphoma about 2 years after completing a course of nivolumab as fourth line treatment for metastatic disease. In a review of the WHO pharmacovigilance database, the authors found 0.1% cases of lymphoma in patients who had received nivolumab, pembrolizumab, or ipilimumab. The development of lymphoma in this context is a rare phenomenon.”
