Hyper-progressors after Immunotherapy: Analysis of Genomic Alterations Associated with Accelerated Growth Rate

摘要

PurposeCheckpoint inhibitors demonstrate salutary anti-cancer effects including long-term remissions. PD-L1 expression/amplification, high mutational burden and mismatch repair-deficiency correlate with response. We have, however, observed a subset of patients who appear to be “hyper-progressors,” with a greatly accelerated rate of tumor growth and clinical deterioration compared to pre-therapy, which was also recently reported by Institut Gustave Roussy. The current study investigated potential genomic markers associated with “hyper-progression” after immunotherapy.
