Table 4 Correlation between duration of corticosteroid treatment and levels of insulin or growth hormone in cyst fluid and serum

From: Glioblastoma microenvironment contains multiple hormonal and non-hormonal growth-stimulating factors

   Pearson’s r =  p-value
Insulin Cyst fluid (n = 25)  + 0.48 0.015
Serum (n = 15)  + 0.11 0.7
Growth hormone Cyst fluid (n = 25) − 0.50 0.011
Serum (n = 15) − 0.07 0.8
  1. Prior to neurosurgery, 25 patients with cystic glioblastoma received corticosteroid treatment for 0–30 days to reduce peri-tumoral edema. For 15 patients parallel serum samples were available for analysis. Data are Pearson’s correlation coefficients and corresponding p-values
