The Association Between Hot Flashes and Renal Dysfunction After Androgen Deprivation Therapy With Radiotherapy in Japanese Patients With High-risk Prostate Cancer.

We investigated the changes in and characteristics of renal function in Japanese patients with high-risk prostate cancer (PCa) who underwent radiotherapy and long-term androgen deprivation therapy (ADT), including those seen after the ADT was discontinued.

Among 60 patients who were pathologically diagnosed with PCa and received ADT for 24 months and radiotherapy, 36 patients who underwent treatment for stage B or C PCa were eligible. We assessed renal function using the estimated glomerular filtration rate (eGFR) and investigated the rate of change in the eGFR (ΔeGFR) during and after ADT. Univariate and multivariate logistic analyses were carried out to identify clinical factors that were significantly associated with renal dysfunction at 36 months.

The incidence of renal dysfunction at 36 months was 75% (27/36). Multivariate analysis showed that the presence/absence of HF was an independent predictor of renal dysfunction at 36 months.

Renal function tended to recover after ADT was received for 24 months and subsequently discontinued. The presence/absence of HF represents new and meaningful information for patients receiving ADT, and high-risk PCa patients prior to ADT.
