PMID 40849968WHAT IT FOUND
In men with prostate cancer receiving radiation, general, physical, and mental fatigue worsened during treatment, while emotional fatigue improved.
After treatment, general, physical, and mental fatigue improved, but emotional fatigue stayed steady.
Key findings
01During treatment, general, physical, and mental fatigue worsened, while emotional fatigue improved.
02After treatment completion, general, physical, and mental fatigue improved, while emotional fatigue remained steady.
03Anxiety and depression were positively correlated with each fatigue dimension during treatment and after treatment.

What it does not show
This was a secondary analysis of a small sample, so the analysis was descriptive and exploratory. The sample was homogeneous and mostly White, so the results may not apply to other groups. Many variables were examined, so some correlations may be chance findings. Pain and difficulty sleeping were measured with brief items, which may have missed stronger relationships. The anxiety and depression measures had only marginal reliability in this sample. The fatigue questionnaire showed a floor effect and little score variation, and its clinically important difference was reported only in women with breast cancer.

The authors declared no conflicts of interest.
The easy way to misread this
Do not treat these correlations as evidence that any treatment reduces fatigue. The study was exploratory, used a small sample, and tested many variables, so some associations may be chance.
