Abstract
Purpose: Cortisol plays an important role in the physical status of patients with end-stage lung cancer, but the association of urine cortisol levels with TNM stage/performance status (PS) is unclear in patients with advanced lung cancer receiving chemotherapy. The objective of this study was to examine this association. Methods: In this single-center, retrospective, observational study, cortisol concentrations in 24-h pooled urine from 22 patients with advanced lung cancer were measured over 2 days. The mean concentration in each patient was compared with PS, TNM stage, and serum sodium and potassium ion levels. Results: The 24-h urine cortisol levels were higher in PS2 or PS3 cases compared to PS1 (p < 0.05) and increased proportionally with PS. Urine cortisol also increased in N2 or N3 cases compared to N1 (p < 0.01) and also increased in M1 cases (p < 0.05). Urine cortisol levels were negatively correlated with serum sodium (R = −0.49, p < 0.05) and had a tendency for a positive correlation with serum potassium (R = 0.40, p = 0.06). Conclusion: The 24-h urine cortisol level increased in patients with advanced lung cancer undergoing chemotherapy. Low serum levels of potassium and high levels of sodium may indicate relative adrenal insufficiency.
