Large-scale study provides real-world data on rare side effect of cancer immunotherapy

Researchers led by investigators at Mass General Brigham have published valuable information about a rare but serious complication of anti-cancer immunotherapy, providing the first large-scale description of its risk factors and clinical course, and underscoring the importance of early diagnosis and treatment. The findings are published in Blood and simultaneously presented at the American Society of Hematology Annual Meeting.
