Abstract

Oncology has recently undergone a revolutionary change with widespread adoption of immunotherapy for many cancers. Immunotherapy using monoclonal antibodies against checkpoint molecules, including programmed death (PD)-1, PD ligand (PD-L)1, and cytotoxic T lymphocyte-associated antigen (CTLA)-4, is effective in a significant subset of patients. However, immune-related adverse events (irAEs) have emerged as frequent complications of checkpoint blockade, likely due to the physiological role of checkpoint pathways in regulating adaptive immunity and preventing autoimmunity. As immunotherapy becomes more common, a better understanding of the etiology of irAEs and ways to limit these events is needed. At the same time, studying these new therapy-related disorders provides an opportunity to better understand naturally occurring human autoimmune and inflammatory disorders, with the potential to improve therapies for cancer and autoimmune diseases.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The organ systems affected, severity, and timing of immune-related adverse events vary between anti-CTLA-4 and anti-PD-1/PD-L1 agents and their combinations.

    “The breadth of systems affected, severity and timing of irAEs can all vary between agents, specifically between anti-CTLA-4 agents and anti-PD-1/PD-L1 and combinations thereof”

  • Immune-related adverse events are common: low-grade events occur in more than 90% of patients, and severe events occur in 20-60%.

    “irAEs are common, with a low-grade (Grade 1-2) effect observed in up to more than 90% of patients, while more severe effects (Grades 3-5) can range from 20-60%”

  • Immune-related adverse events include over 70 pathologies affecting nearly every organ system.

    “irAEs comprise over 70 different pathologies affecting nearly every organ system including the neurologic, genitourinary, gastrointestinal, pulmonary, cardiovascular, and integumentary systems”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
