Quantification of the Leydig cell compartment in testicular biopsies and association with biochemical Leydig cell dysfunction in testicular cancer survivors. Andrology 2018; 6:748-755. [PMID: 29981219 DOI: 10.1111/andr.12508] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2018] [Revised: 04/04/2018] [Accepted: 05/09/2018] [Indexed: 11/30/2022]
Abstract
A simple histological method to evaluate the Leydig cell compartment is lacking. We aimed to establish such a method and to investigate if Leydig cell hyperplasia of the biopsy contralateral to the tumour-bearing testicle in patients with testicular germ cell cancer is associated with biochemical signs of Leydig cell dysfunction after long-term follow-up. A case group of 50 long-term testicular germ cell cancer survivors without human chorionic gonadotropin elevation, 10 testicular germ cell cancer patients with elevated human chorionic gonadotropin and 10 controls without testicular malignancy were included. For each subject, 2-4 representative sections from their testicular biopsies were selected for analysis. Using the image processing program ImageJ (V.1.48, NIH), an area with a minimum of 50 tubules was selected and delineated (total selected area) and the total Leydig cell area was calculated by adding up every delineated Leydig cell group within the total selected area. Four different methods were tested for the ability to quantify the Leydig cell compartment. In the 50 testicular germ cell cancer survivors, associations between the area of the Leydig cell compartment and serum levels of testosterone and luteinising hormone were investigated using linear regression analysis. The Leydig cell compartment was best quantified by the total Leydig cell area/total selected area index, which was significantly larger in the human chorionic gonadotropin-positive patients than in controls (P = 0.00001). In the 50 human chorionic gonadotropin-negative testicular germ cell cancer survivors, increasing total Leydig cell area/total selected area was significantly associated with decreased levels of total testosterone and decreased total testosterone/luteinising hormone ratio after a median of 9-year follow-up. In conclusion, a new simple method, total Leydig cell area/total selected area, was established to estimate the Leydig cell compartment in testicular biopsies. The index identified Leydig cell hyperplasia in the contralateral biopsy in patients with testicular germ cell cancer, and it was associated with long-term biochemical Leydig cell dysfunction. Although in testicular germ cell cancer survivors, the clinical value is limited because the contralateral biopsies are not commonly available, we propose a closer andrological follow-up in any patient with an increased total Leydig cell area/total selected area index.

Abstract
This paper will consist of two parts. In the first, further support is given to the proposal that offspring sex ratios (proportions male) may usefully be regarded as indicators of public health. In the second, it is shown that sex ratios may help in the identification of the causes and effects of several pathologies that seriously impinge on public health viz. autism, testicular cancer, hepatitis B and toxoplasmosis.

Abstract
Cancer and its treatment can lead in men to testosterone deficiency, accompanied by somatic and mental symptoms. Germ cell tumours and their treatment may disturb the pituitary-gonadal axis, hence leading to significant clinical abnormalities. In some prostate cancer patients, castration, temporary or permanent, is a desired therapeutic condition. Yet, it is burdened with various side effects of complex intensity and significance. Last but not least, patients in the terminal stage of a malignancy present with low testosterone concentrations as a part of anorexia-cachexia syndrome. Oncological management of such patients disturbs their homeostasis, androgen metabolism included, which results in numerous complications and worsens their quality of life. In the present paper, we analysed the frequency and sequelae of testosterone deficiency in some clinical scenarios, on the basis of original papers, meta-analyses and reviews available in PubMed. Androgen secretion disorders in male cancer patients depend on a cancer type, stage and methods of treatment. Number of testicular cancer survivors is increasing, and as a consequence, more patients cope with late complications, testosterone deficiency included. Hormone therapy in prostate cancer patients significantly prolongs survival, and then numerous men experience long-term adverse effects of androgen deficiency. Those, in turn, particularly the metabolic syndrome, may contribute to increased mortality. Androgen deficiency is a part of cancer anorexia-cachexia syndrome. The role of androgen deficiency in cancer patients is still under debate, and further studies are urgently needed to establish appropriate clinical guidelines.

Dynamics of hormonal disorders following unilateral orchiectomy for a testicular tumor. Med Oncol 2017; 34:84. [PMID: 28389909 PMCID: PMC5384966 DOI: 10.1007/s12032-017-0943-0] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2017] [Accepted: 04/04/2017] [Indexed: 11/06/2022]
Abstract
Testicular tumors and their treatment interfere with homeostasis, hormonal status included. The aim of the study was to evaluate hormonal disorders of the pituitary–gonadal axis in men treated for testicular tumors. One hundred twenty-eight men treated for a unilateral testicular tumor at our institution were included. The hormonal status was prospectively evaluated in 62 patients before orchiectomy, 120 patients 1 month after orchiectomy and 110 patients at least 1 year after the treatment. The concentrations of human chorionic gonadotropin (hCG), testosterone (T), estradiol, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and prolactin were measured. The clinically significant testosterone deficiency was defined either as testosterone <2.31 ng/mL or testosterone within the range of 2.31–3.46 ng/mL but simultaneous with T/LH ratio ≤1. Changes in hormone levels were significant: LH and FSH rose in the course of observation, and the concentration of hCG, testosterone, estradiol decreased. PRL concentration was the lowest at 1 month after orchiectomy. In multivariate analysis, the risk of the clinically significant testosterone deficiency was 0.2107 (95% CI 0.1206–0.3419) prior to orchiectomy, 0.3894 (95% CI 0.2983–0.4889) 1 month after surgery and 0.4972 (95% CI 0.3951–0.5995) 1 year after the treatment. The estradiol concentration was elevated in 40% of patients with recently diagnosed testicular cancer and that was correlated with a higher risk of testosterone deficiency after the treatment completion. Hormonal disorders of the pituitary–gonadal axis in men treated for testicular tumors are frequent. The malignant tissue triggers paraneoplastic disorders that additionally disturb the hormonal equilibrium.

Abstract
Testicular cancer (TC) is the most common solid cancer in men between the third and fourth decade of life. Due to successful treatment approaches, TC survivors (TCSs) have long life expectancy, but with numerous potential long-term sequelae, including sexual dysfunction. We investigated predictors of long-term normal sexual function (SF) recovery in TCSs. Sociodemographic, medical, and psychometric data were analyzed in 143 Caucasian-European TCSs, who underwent orchiectomy at a single institution. Health-significant comorbidities were scored with the Charlson Comorbidity Index (CCI). Patients completed the International Index of Erectile Function (IIEF). Statistical models tested the association between predictors (including age at surgery, body mass index, CCI, and adjuvant therapy: radiotherapy [RT], chemotherapy [CT], CT followed by retroperitoneal lymph node dissection [RPLND] and RPLND alone) and the long-term recovery of normal SF (defined as IIEF-erectile function [EF] ≥26, and sexual desire [SD], intercourse satisfaction [IS] orgasmic function [OF], and overall satisfaction [OS] domain scores in the upper tertiles). At a mean follow-up of 86 months, 35 (25.5%) TCSs had erectile dysfunction (ED), with 16 (11.2%) experiencing severe ED. Median time of EF recovery was 60, 60, and 70 months after CT, RT, and RPLND, respectively. Only adjuvant RT emerged as an independent predictor of nonrecovery of normal EF (HR: 0.55, P= 0.01). Neither adjuvant CT nor CT plus RPLND or RPLND alone significantly impaired the recovery of normal erections. Adjuvant therapy was not associated with impaired recovery of normal sexuality as a whole, considering the IIEF-SD, -OF, -IS, and OS domains.

Abstract
This study summarizes the literature on the prevalence, incidence, and proportion of patients receiving treatment for male hypogonadism and a systematic literature search was performed for articles published in the last 20 years. Of the 97 studies identified, 96 examined the prevalence, 2 examined the incidence, and 4 examined the proportion of males with hypogonadism patients receiving treatment. Based on studies conducted in Europe and USA, the prevalence of hypogonadism in the general population ranged from 2.1% to 12.8% of middle-aged to older men, with an estimated incidence of 12 new cases per 1,000 person-years. Prevalence was higher among patients with comorbid conditions, such as type 2 diabetes mellitus and obesity. Approximately 10–12% of men with hypogonadism were receiving testosterone treatment. This literature review suggests that there is potentially a significant burden of hypogonadism in the general population. Burden seems to increase with age and in the presence of certain disease conditions. Data suggests that many hypogonadal men who may benefit from testosterone replacement are not receiving treatment. This may be the result of underdiagnosis of the disease, lack of awareness by patients or physicians, irregularities surrounding the diagnostic criteria, and deficiency of long-term safety studies.

Abstract
BACKGROUND The treatment of testicular intraepithelial neoplasia (TIN), the progenitor of testicular germ cell tumours (GCTs), is based on little data. PATIENTS AND METHODS Two hundred and twenty-eight GCT patients with contralateral TIN were retrospectively enrolled. Ten had surveillance, 122 radiotherapy to testis with 18-20 Gy, 30 cisplatin-based chemotherapy (two cycles), 51 chemotherapy (three cycles), and 15 carboplatin. The study end point was a malignant event (ME), defined as detection of TIN upon control biopsy or occurrence of a second GCT. The Secondary end point was hypogonadism during follow-up. RESULTS Numbers, proportions of ME, and median event-free survival (EFS) times were: radiotherapy N = 3, 2.5%, 11.08 years; chemotherapy (two cycles) N = 15, 50%, 3.0 years; chemotherapy (three cycles) N = 12, 23.5%, 9.83 years; carboplatin N = 10, 66%, 0.9 years; surveillance N = 5, 50%, 7.08 years. EFS is significantly different among the groups. Hypogonadism rates were in radiotherapy patients 30.8%, chemotherapy (two cycles) 13%, chemotherapy (three cycles) 17.8%, carboplatin 40%, surveillance 40%. CONCLUSIONS Local radiotherapy is highly efficacious in curing TIN. Chemotherapy is significantly less effective and the cure rates are dose-dependent. Though hypogonadism occurs in one-third of patients, radiotherapy with 20 Gy remains the standard management of TIN.
