TB activation can occur in various organs and TB-related fatalities have been reported. TB screening before starting immunotherapy should be considered in high-risk patient populations. Further research, including prospective studies with patients whose baseline TB status is known, is necessary to better understand the incidence of TB reactivation during ICI therapy and how best to manage TB that develops during immunotherapy.

Median age was 61 (range: 49-87). Twelve (75%) were male and 4 (25%) were female. Lung cancer was the most common type of cancer (n = 8), followed by melanoma (n = 3) and head and neck cancer (n = 3). Median time to TB reactivation after initiation of ICI therapy was 6.3 months (range: 1-24 months). Two (13%) patients died of complications of TB (spinal cord compression, GI perforation). TB reactivation in organs (pericardium, bone, liver, and GI track; one each) other than the lungs has been documented. We did not find any cases of TB reactivation that occurred during anti-CTLA-4 therapy.
