  1. Cyst fluid and serum from 15 glioblastoma patients were analyzed with respect to hormones and serum proteins. Data are mean ± SD values. Estradiol was not detected in several serum samples and a ratio could therefore not be calculated. Abbreviations: APOA1: apolipoprotein A–I; EPO: erythropoietin; GH: growth hormone; IGF-1: insulin-like growth factor 1; SHBG: sex hormone-binding globulin; T3: triiodothyronine
