The Claim
Transient cortisol levels below 150 nmol/L during dexamethasone-based chemotherapy are not reliably indicative of adrenal insufficiency, as they may arise from temporary suppression, measurement variability, or stress-induced fluctuations.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
During dexamethasone chemotherapy, cortisol levels below 150 nmol/L often occur due to drug effects, measurement error, or stress, and do not necessarily mean the adrenal glands are not functioning properly.
See the scientific wording
The clinical relevance of transient cortisol levels below 150 nmol/L during dexamethasone-based chemotherapy remains uncertain, as these values may reflect temporary suppression, measurement variability, or stress-induced fluctuations rather than true adrenal insufficiency.
A strong synthetic steroid enters the body and tells the brain and pituitary gland to stop signaling the adrenal glands to make cortisol. Without that signal, the adrenal glands produce less cortisol, causing levels to drop below normal for a short time. The body eventually recovers and resumes normal cortisol production, so the low levels are temporary and not a sign of permanent damage.
What the research says
1 studySome patients on this chemo had low cortisol readings, but the study found these dips weren’t consistent or significant — they went up again, so they probably weren’t a real problem, just temporary blips.
