Purpose: To assess longitudinal long-term alterations of testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) in testicular cancer survivors (TCSs). Patients and Methods: In all, 307 TCSs treated from 1980 to 1994 provided blood samples after orchiectomy but before further treatment, at Survey I (SI; 1998-2002), and Survey II (SII; 2007-2008). Levels of sex hormones were categorized according to quartiles and reference range (2.5 and 97.5 percentiles) of 599 controls for each decadal age group. TCSs were categorized according to treatment: surgery, radiotherapy (RT), or chemotherapy (CT). The risk of higher (LH) or lower (testosterone) levels was assessed with ?2 test (FSH) or ordinal logistic regression analysis and expressed as odds ratios (ORs) with 95% CIs. Results: Risk of lower testosterone and higher LH and FSH levels was significantly increased for TCSs at all time points after RT or CT. At SII, ORs were 3.3 (95% CI, 2.3 to 4.7)…(ver más)
