Abstract
BACKGROUND: Twenty to thirty percent of testicular cancer (TC) survivors have elevated serum levels of luteinising hormone (LH) with or without corresponding low testosterone levels (Leydig cell dysfunction) during clinical follow-up for TC. However, it remains to be clarified if this subgroup of TC survivors has an increased long-term risk of systemic inflammation and metabolic syndrome (MetS) when compared with TC survivors with normal Leydig cell function during follow-up. PATIENTS AND METHODS: TC survivors with Leydig cell dysfunction and a control group of TC survivors with normal Leydig cell function during follow-up were eligible for participation in the study. Markers of systemic inflammation and prevalence of MetS were compared between TC survivors with Leydig cell dysfunction and the control group. RESULTS: Of 158 included TC survivors, 28 (18%) had uncompensated Leydig cell dysfunction, 59 (37%) had compensated Leydig cell dysfunction and 71 (45%) had normal Leydig cell function during follow-up. MetS and markers of systemic inflammation were evaluated at a median follow-up of 9.7 years (interquartile range 4.1-17.1) after TC treatment. The prevalence of MetS was significantly lower among patients with compensated Leydig cell dysfunction during follow-up (12% versus 27%, p = 0.04), whereas there was no difference between TC survivors with uncompensated Leydig cell dysfunction and controls (33% versus 27%, p = 0.5). Apart from high-sensitivity C-reactive protein which was higher in TC survivors with uncompensated Leydig cell dysfunction during follow-up, there was no evidence of increased systemic inflammation in patients with Leydig cell dysfunction during clinical follow-up. Total testosterone at follow-up was significantly associated with MetS, whereas there was no association between LH and MetS. CONCLUSION: We did not find evidence that TC survivors with Leydig cell dysfunction during clinical follow-up had increased long-term risk of MetS. Total testosterone at follow-up was significantly associated with MetS. The study is registered at www.clinicaltrials.govNCT02240966.
