Objective:

To evaluate longitudinal changes in morning cortisol and ACTH concentrations in breast cancer patients receiving dexamethasone as chemotherapy premedication, assessing potential suppression of the HPA axis.

Key Findings:
  • Morning cortisol and ACTH concentrations showed an overall downward tendency during treatment.
  • No statistically significant changes were observed in cortisol or ACTH concentrations.
  • The study did not demonstrate significant suppression of HPA axis function during intermittent high-dose dexamethasone administration.
Interpretation:

The findings suggest limitations of single cortisol measurements and emphasize the need for a longitudinal approach to assess adrenal function in oncology patients.

Limitations:
  • Small sample size of 47 participants.
  • Lack of dynamic testing to better evaluate HPA axis function.
  • Single time-point measurements may not accurately reflect adrenal function.
Conclusion:

Further studies incorporating dynamic testing are required to determine the optimal method for evaluating HPA axis function during intermittent glucocorticoid exposure.
