Serum testosterone level is a useful biomarker for determining the optimal treatment for castration-resistant prostate cancer. Urol Oncol. 2019 May 16;: Authors: Hashimoto K, Tabata H, Shindo T, Tanaka T, Hashimoto J, Inoue R, Muranaka T, Hotta H, Yanase M, Kunishima Y, Takahashi A, Masumori N, Sapporo Medical University Urologic Oncology Consortium (SUOC) Abstract OBJECTIVE: Our aim was to evaluate the usefulness of serum testosterone to guide treatment decision for castration-resistant prostate cancer (CRPC). METHODS: We conducted a retrospective analysis of 115 patients with CRPC treated with either abiraterone (n = 43) or enzalutamide (n = 72). A serum testosterone level was measured at time of starting of abiraterone or enzalutamide. We determined whether serum testosterone influenced the outcomes of androgen receptor (AR)-targeted therapy. RESULTS: In the very-low testosterone group (
To identify variables that predict persistent hypogonadism and castration in patients with prostate cancer (PCa) treated with brachytherapy (BT).
Conclusion: In older men with low testosterone levels without well-established medical conditions known to cause hypogonadism, testosterone therapy may provide small improvements in sexual functioning and quality of life but little to no benefit for other common symptoms of aging. Long-term efficacy and safety are unknown. Primary Funding Source: American College of Physicians. (PROSPERO: CRD42018096585). PMID: 31905375 [PubMed - as supplied by publisher]
In this study, we evaluated the performance of multiparametric MRI (mpMRI) and mpMRI-TRUS fusion biopsy in hypogonadal patients.Materials and methodsClinical and pathologic data from a prospectively maintained, single-institution database of patients who underwent 3T mpMRI and fusion biopsy between 2007 and 2016 were analyzed. Hypogonadism was defined by an institutional cutoff of serum testosterone ≤ 180 ng/dL; T2, DWI, and DCE scores were calculated from mpMRI. Cancer detection rates were compared by Chi-square tests. Multivariate logistic regression was undertaken to evaluate the impact of hypogonadism on...
To evaluate whether total serum PSA, free-PSA ratio and PSA density have similar diagnostic properties for detecting prostate cancer (PCa) and clinically-significant (cs) PCa in men with normal testosterone compared to men with low testosterone with a prior negative biopsy.

CONCLUSION: We propose seeking for hypogonadism caused by endocrine conditions or ADT in men presenting with TdP. Caution is warranted when ADT is used in situations at risk of TdP. Testosterone may be useful to treat or prevent TdP. PMID: 31477476 [PubMed - as supplied by publisher]
Several studies highlight that testosterone deficiency is associated and predicts increased risk of developing metabolic disorders, and, that it is highly prevalent in obesity, metabolic syndrome and type-2 diabetes mellitus. Models of gonadotropin releasing hormone deficiency and androgen deprivation in patients with prostate cancer suggest that hypogonadotropic hypogonadism might contribute to onset or further worsen metabolic conditions by means of increased fat mass and insulin resistance. Nevertheless, in functional hypogonadism, such as late onset hypogonadism, the relationship between hypogonadotropic hypogonadism a...
CONCLUSIONS: In this systematic review and meta-analysis, we did not observe higher rate of BCR after TRT for nonmetastatic CaP patients after definitive local therapy. Based on these data, others and we have outlined a phase I/II trial assessing the safety and benefits of TRT in select men with secondary symptomatic hypogonadism who have no active disease after definitive local CaP therapy with curative intent.

CONCLUSION: The principal findings of this investigation were that low testosterone is correlated with elevated CgA levels, and these two parameters are associated with more aggressive grades and higher pathological stages of prostatic adenocarcinoma.

Purpose of review The aim of this study is to summarize recently published literature examining androgens and depression. Recent findings The impact of androgen levels, androgen replacement therapy and pharmacologic androgen deprivation on depression and depressive symptoms remain active areas of investigation. Recent publications support the finding that testosterone replacement therapy in men with low testosterone may improve depression, and that androgen deprivation therapy in men with prostate cancer may contribute to depression. Summary We review the recent literature on androgens and depression and highlight key developments.
