Abstract BACKGROUND: Fatigue was reported as the most common any-grade adverse event (18.3%), and the most common grade 3 or higher immune-related adverse event (irAE) (0.89%) in patients receiving PD-1/PD-L1 checkpoint inhibitors in clinical trial. METHODS: The aim of this retrospective multicenter study was to evaluate the correlations between "early ir-fatigue", "delayed ir-fatigue", and clinical outcomes in cancer patients receiving PD-1/PD-L1 inhibitors in clinical practice. RESULTS: 517 patients were evaluated.

Background: Several studies have found an association between higher body mass index (BMI) and improved clinical outcomes in cancer patients receiving programmed cell death protein-1 (PD-1)/programmed cell death-ligand 1 (PD-L1) checkpoint inhibitors. In a previous study, we found that overweight/obese patients were significantly more likely to experience any grade immune-related adverse events (irAEs) compared to non-overweight patients.

Background: Data on spectrum and grade of immune-related adverse events (irAEs) in long-term responders to immune checkpoint inhibitors (ICIs) are lacking. Methods: We performed a retrospective multicenter study to characterized irAEs occurring after a 12-months minimum treatment period with PD-(L)1 ICIs in patients with advanced cancer. IrAEs were categorized into ‘early’ (≤12 months) and ‘late’ (>12 months). Results: From September 2013 to October 2019, 436 consecutive patients were evaluated.
