Endocrine toxicities of immune checkpoint inhibitors
Open accessAbstract
Immune checkpoint inhibitors (ICIs) are monoclonal antibodies that target two key signalling pathways related to T cell activation and exhaustion, by binding to and inhibiting cytotoxic T lymphocyte antigen 4 (CTLA4) or PD1 and its ligand PDL1. ICIs, such as nivolumab, pembrolizumab and ipilimumab, are approved for the treatment of numerous and diverse cancer types, in various combination regimens, and are now an established cornerstone of cancer therapeutics. Toxicities induced by ICIs are autoimmune in nature and are referred to as immune-related adverse events (irAEs); these events can affect any organ system in an unpredictable fashion. Importantly, irAEs can manifest as endocrinopathies involving the thyroid (hypothyroidism or thyrotoxicosis), pituitary (hypophysitis), adrenal glands (adrenal insufficiency) and pancreas (diabetes mellitus). These events are a frequent source of acute and persistent morbidity in patients treated with ICIs and can even be fatal. Over the past few years, there has been a growing understanding of the underlying pathogenesis of irAEs that has led to the development of more effective management strategies. Herein, we review the current understanding of the pathobiology, clinical manifestations and treatment approaches to endocrine toxicities arising from ICIs. Immune checkpoint inhibitors (ICIs) are now an established cornerstone of cancer therapeutics; however, ICIs are associated with toxicities in various organs, termed immune-related adverse events. This Review highlights current understanding in ICI-induced endocrinopathies, including epidemiology, aetiology, clinical manifestations and approaches to treatment. Immune checkpoint inhibitors (ICIs) are now a cornerstone of cancer therapies and are associated with long-term treatment responses, but they can also cause inflammatory toxicities in endocrine and other organs. The most common ICI-induced endocrine toxicity is hypothyroidism, which occurs in 10–20% of treated patients, is often preceded by transient thyrotoxicosis, and usually persists after ICI therapy completion. Hypopituitarism, which might co-occur with hypophysitis, is a condition nearly unique to ICI therapy, and is a clinically relevant cause of morbidity and rarely mortality. ICI-associated diabetes mellitus (ICI-DM) occurs rarely (<1% of treated patients) but resembles type 1 diabetes mellitus, and patients can present with diabetic ketoacidosis. Treatment for ICI-induced endocrinopathies involves hormone replacement therapy; patients can continue or resume their ICI once clinically stable.

Overview

Written from the paper’s full text.
TL;DR
This review summarizes the pathobiology, clinical presentation, monitoring, and management of endocrine toxicities from immune checkpoint inhibitors, especially thyroid, pituitary, adrenal, and pancreatic beta-cell events. It emphasizes that these endocrinopathies are common, often permanent, and generally managed with hormone replacement rather than high-dose steroids or ICI discontinuation.
Key findings
- Endocrine events affect up to 40% of ICI-treated patients; the most commonly affected organs are thyroid, pituitary, adrenal, and pancreatic beta cells.
- Thyroid dysfunction occurs in approximately 10% of anti-PD-1/PD-L1 monotherapy patients, up to 15–20% with combination PD-1/CTLA-4 blockade, and only 5% with ipilimumab monotherapy; hypothyroidism predominates, preceded by destructive thyroiditis in 30–40% of anti-PD-1/PD-L1 cases and up to two-thirds of combination cases.
- Hypophysitis/hypopituitarism occurs in up to 10% of anti-CTLA-4-based therapy patients but only 0.5–1% of anti-PD-1/PD-L1 monotherapy patients; median onset is 9–12 weeks for ipilimumab-treated patients and 26 weeks for anti-PD-1/PD-L1.
- ICI-associated diabetes mellitus occurs in slightly less than 1% of ICI-treated patients, with approximately 97% of reported cases on anti-PD-1/PD-L1 or combination therapy; 38–71% present in diabetic ketoacidosis, and median onset is 7–17 weeks with a range of 1–228 weeks.
Methods
- Narrative review of the current understanding of pathobiology, clinical manifestations, and treatment approaches to endocrine toxicities from immune checkpoint inhibitors.
- No primary data collection or systematic review methodology is described; the paper synthesizes published literature, guidelines, case reports, and meta-analyses.
- Organ-specific sections cover thyroid, pituitary, primary adrenal insufficiency, diabetes mellitus, and rare endocrinopathies, with monitoring and treatment recommendations.
Limitations
- The paper states that all treatment for immune-related adverse events is based on expert opinion and clinical judgment rather than large-scale clinical trials or high-level evidence.
- The paper notes that histologic confirmation of the hypothesis that endocrine toxicity destroys hormone-producing cells is lacking, human mechanistic studies are limited, routine pituitary/adrenal monitoring is controversial, and rare endocrinopathies are described only in case reports.
- Evident from the text: as a narrative review, it does not describe a systematic search strategy, inclusion criteria, or formal quality assessment of the cited evidence.

The authors state this as an assumption.
ICI-induced endocrine toxicities result in permanent, irreversible endocrine dysfunction.
“they are presumed to result in permanent, irreversible endocrine dysfunction.”
The paper relies on this without support.
The inflammatory phase of endocrine toxicity is often asymptomatic, and symptoms arise only after most hormone-secreting cells have been destroyed.
“the inflammatory phase of the toxicity is often asymptomatic, and symptoms arise only in the terminal phase when most hormone-secreting cells have been destroyed and anti-inflammatory therapy is unlikely to be of benefit.”
The authors state this as an assumption.
The immune activation damages or destroys all or nearly all hormone-producing cells, precluding resumption of hormone production.
“A possible explanation for this difference is that the immune activation damages or destroys all (or nearly all) of the relatively small number of hormone producing cells, thus precluding the ability to resume hormone production, though histologic confirmation of this hypothesis is lacking.”
The paper relies on this without support.
Severe adrenal insufficiency, whether primary or secondary, is life-threatening.
“Given the life-threatening nature of severe adrenal insufficiency, whether primary or secondary”
The paper relies on this without support.
Immune checkpoint inhibitor-associated diabetes mellitus is generally insulin-dependent diabetes.
“Since ICI-DM is generally insulin-dependent diabetes”
The paper relies on this without support.
Presenting symptoms of immune checkpoint inhibitor-associated diabetes mellitus include polyuria, polydipsia, fatigue, and, if presenting in diabetic ketoacidosis, abdominal pain and nausea.
“Presenting symptoms of ICI-DM include polyuria, polydipsia, and fatigue, as well as abdominal pain and nausea if presenting in DKA.”
The paper relies on this without support.
Primary adrenal insufficiency clinically resembles secondary hypocortisolism with malaise, fatigue, and nausea, but more often includes hypotension and/or adrenal crisis.
“Clinical presentation is similar to secondary hypocortisolism, with malaise, fatigue, and nausea, but differs in that it is more frequently associated with hypotension and/or adrenal crisis”
The paper relies on this without support.
Immune checkpoint inhibitor-associated diabetes mellitus frequently co-occurs with other immune-related adverse events, including pancreatitis, thyroiditis, hypophysitis, or colitis.
“ICI-DM is frequently co-morbid with other irAEs, including pancreatitis, thyroidits, hypophysitis, or colitis”

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.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
