Purpose: To evaluate the prevalence of overweight/obesity and dyslipidemia in patients with intracranial germ cell tumor (iGCT), and to explore the risk factors of it.
Methods: iGCT patients visiting Peking Union Medical College Hospital between Jan 2008 to Oct 2020 were included. The prevalence of overweight/obesity and dyslipidemia was calculated. Mixed-effects models were used to evaluate the relationship between BMI z-scores, concentration of lipid profiles and potential risk factors.
Results: One hundred and six patients were included. The median follow-up time was 27 (IQR 5-59) months. The number of patients diagnosed with overweight/obesity and dyslipidemia were 49 (46.2%) and 86 (81.1%) during visits. Higher BMI z-scores were associated with treatment (mean difference (MD) 0.51, 95%CI 0.31-0.72), surgical biopsies (MD 0.71, 95%CI 0.16-1.25), adrenal insufficiency (MD 0.37, 95%CI 0.07-0.68), hypothyroidism (MD 0.35, 95%CI 0.06-0.63), glucocorticoid supplementation (MD 0.64, 95%CI 0.40-0.87), and thyroxine supplementation (MD 0.48, 95%CI 0.24-0.72). Hypothalamus involvement was associated with increased TC (MD 0.52, 95%CI 0.06-0.98), TG (MD 0.36, 95%CI 0.01-0.72), LDL-C (MD 0.60, 95%CI 0.20-0.98), and decreased HDL-C (MD - 0.23, 95%CI - 0.44 to - 0.02). Higher TC (MD 0.53, 95%CI 0.26-0.80) and LDL-C (MD 0.39, 95%CI 0.17-0.62) were observed in patients after treatment. Glucocorticoid supplementation was associated with increased TC (MD 0.70, 95%CI 0.38-1.03), LDL-C (MD 0.51, 95%CI 0.24-0.78), and HDL-C (MD 0.25, 95%CI 0.09-0.40), while sex hormone supplementation was associated with decreased TC (MD - 0.74, 95%CI - 1.2 to - 0.29) and TG (MD - 0.47, 95%CI - 0.86 to - 0.08).
Conclusion: Overweight/obesity and dyslipidemia were high prevalent in iGCT patients and should be screened during follow-ups.
