Ebrahimi P, Karami M, Hosseini-Berneti SH, Lashkarbolouki AH, Keshtegar S, Ghezel MA, Nikbakht HA. Examining the trend of mortality of genitourinary system cancers in Babol, North Iran (2013-2021). BMC Urol 2024; 24:161. [PMID: 39080636 PMCID: PMC11289959 DOI: 10.1186/s12894-024-01523-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Accepted: 06/24/2024] [Indexed: 08/02/2024] Open
Abstract
BACKGROUND Cancers of the genitourinary system, particularly prostate, bladder, and kidney cancer, exhibit a high prevalence. Consequently, predicting the morbidity and mortality of genitourinary cancers holds great significance for future planning and implementation. This study aimed to examine the crude and age-standardized rates of mortality and the trend of genitourinary cancers over nine years in northern Iran. METHODS This cross-sectional study used data on the number of deaths attributed to genitourinary cancers recorded in Babol City between 2013 and 2021 through the cause of death registration and classification system. Population estimates were derived from the latest census reports. Subsequently, crude and age-standardized rates, as well as trends for genitourinary cancers, were calculated. RESULTS A total of 307 deaths occurred, with an average age of 75.6 ± 14.3 years due to genitourinary cancers. The crude and age-standardized rates of genitourinary cancers increased from 2.7 and 1.9 per hundred thousand people in 2013 to 7.7 and 5.9 per hundred thousand people in 2021, respectively. Over the study period, death rates significantly rose for men (P < 0.001) and remained constant for women (P = 0.444). Examination of genitourinary cancers revealed an upward trend for bladder (P = 0.012) and prostate (P = 0.012) cancers, while a stable trend was observed for kidney (P = 0.070) and testicular (P = 0.139) cancers. CONCLUSIONS The age-standardized rate and trend of genitourinary cancers are rising. Consequently, this study emphasizes the importance of prevention through screening programs, raising awareness, and utilizing appropriate diagnostic methods.

Abstract
Aberrant male germline development can lead to the formation of seminoma, a testicular germ cell tumor. Seminomas are biologically similar to primordial germ cells (PGCs) and many bear an isochromosome 12p [i(12p)] with two additional copies of the short arm of chromosome 12. By mapping seminoma transcriptomes and open chromatin landscape onto a normal human male germline trajectory, we find that seminoma resembles premigratory/migratory PGCs; however, it exhibits enhanced germline and pluripotency programs and upregulation of genes involved in apoptosis, angiogenesis, and MAPK/ERK pathways. Using pluripotent stem cell-derived PGCs from Pallister-Killian syndrome patients mosaic for i(12p), we model seminoma and identify gene dosage effects that may contribute to transformation. As murine seminoma models do not exist, our analyses provide critical insights into genetic, cellular, and signaling programs driving seminoma transformation, and the in vitro platform developed herein permits evaluation of additional signals required for seminoma tumorigenesis.

Long-term quality of life of testicular cancer survivors differs according to applied adjuvant treatment and tumour type. J Cancer Surviv 2024:10.1007/s11764-024-01580-9. [PMID: 38658465 DOI: 10.1007/s11764-024-01580-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 03/29/2024] [Indexed: 04/26/2024]
Abstract
PURPOSE To evaluate the quality of life (QoL) in long-term testicular cancer (TC) survivors. METHODS QoL was assessed in TC survivors treated between March 1976 and December 2004 (n = 625) using the EORTC-QLQ-C30 questionnaire, including a TC module. The assessment was performed at two time points (2006: response rate: n = 201/625 (32.2%), median follow-up (FU): 12.9 years (range 1.1-30.9); 2017: response rate: n = 95/201 (47.3%), median FU: 26.2 years (range: 13.0-41.2)). TC survivors were grouped according to treatment strategy, tumour entity, clinical stage and prognosis group. Linear and multiple linear regression analyses were performed, with age and time of follow-up as possible confounders. RESULTS Radiation therapy (RT) compared to retroperitoneal lymph node dissection (RPLND) was associated with a higher impairment of physical function (2017: β = - 9.038; t(84) = - 2.03; p = 0.045), role function (2017: β = - 12.764; t(84) = - 2.00; p = 0.048), emotional function (2006: β = - 9.501; t(183) = - 2.09; p = 0.038) and nausea (2006: β = 6.679; t(185) = 2.70; p = 0.008). However, RT was associated with a lower impairment of sexual enjoyment (2017: symptoms: β = 26.831; t(64) = 2.66; p = 0.010; functional: β = 22.983; t(65) = 2.36; p = 0.021). Chemotherapy (CT), compared to RPLND was associated with a higher impairment of role (2017: β = - 16.944; t(84) = - 2.62; p = 0.011) and social function (2017: β = - 19.160; t(79) = - 2.56; p = 0.012), more insomnia (2017: β = 19.595; t(84) = 2.25; p = 0.027) and greater concerns about infertility (2017: β = 19.830; t(80) = 2.30; p = 0.024). In terms of tumour type, nonseminomatous germ cell tumour (NSGCT) compared to seminoma survivors had significantly lower impairment of nausea (2006: β = - 4.659; t(187) = - 2.17; p = 0.031), appetite loss (2006: β = - 7.554; t(188) = - 2.77; p = 0.006) and future perspective (2006: β = - 12.146; t(175) = - 2.08; p = 0.039). On the other hand, surviving NSGCT was associated with higher impairment in terms of sexual problems (2006: β = 16.759; t(145) = 3.51; p < 0.001; 2017: β = 21.207; t(63) = 2.73; p = 0.008) and sexual enjoyment (2017: β = - 24.224; t(66) = - 2.76; p = 0.008). CONCLUSIONS The applied adjuvant treatment and the tumour entity had a significant impact on the long-term QoL of TC survivors, even more than 25 years after the completion of therapy. Both RT and CT had a negative impact compared to survivors treated with RPLND, except for sexual concerns. NSGCT survivors had a lower impairment of QoL compared to seminoma survivors, except in terms of sexual concerns. IMPLICATIONS FOR CANCER SURVIVORS Implications for cancer survivors are to raise awareness of aspects of long-term and late effects on QoL in TC survivors; offer supportive care, such as psycho-oncological support or lifestyle modification, if a deterioration in QoL is noticed; and avoid toxic treatment without compromising a cure whenever possible.

Abstract
Testicular germ cell tumors (TGCT) are the most common testicular malignancies. KLRB1 is considered to influence the development and progression of a number of cancers. However, it is unclear how the KLRB1 gene functions in TGCT. First, it was determined the expression level of KLRB1 in TGCT using The Cancer Genome Atlas (TCGA) (The Cancer Genome Atlas) dataset and GTEx (Genotype-Tissue Expression) dataset. The clinical significance and biological functions of KLRB1 were explored using the TCGA dataset, and we analyzed the correlation of the KLRB1 gene with tumor immunity and infiltrating immune cells using gene set variation analysis and the TIMER database. We found that the expression level of KLRB1 was upregulated in TGCT malignant tissues with the corresponding normal tissues as controls, and KLRB1 expression correlated with clinicopathologic features of TGCT. Functional enrichment analysis suggested that KLRB1 might be involved in immune response and inflammatory response. KLRB1 was highly positively correlated with natural killer cell activation in immune response and positively correlated with tumor-infiltrating immune cells. This study demonstrated for the first time the role of KLRB1 in TGCT, which may serve as a new biomarker associated with immune infiltration and provide a potential therapeutic target for the treatment of TGCT.

Abstract
INTRODUCTION Gonadal pediatric tumors are rare, ranking fourth (6%) among pediatric tumors, by Surveillance, Epidemiology, and End Results Program (https:∕∕seer.cancer.gov∕). They have vague symptoms, leading to late discovery, but early detection and identifying its risk factors result in favorable prognosis and reduction of its incidence respectively. PATIENTS, MATERIAL AND METHODS A 10-year retrospective study identified peculiarities and risk factors in 210 children till age 17 with (para)gonadal tumors. RESULTS Stress, pollution (agricultural chemicals, insecticides and metal mine), obesity, breastfeeding ≤5 months, malformations [mainly non-genetic related 67∕87 (77%), especially eye malformation - 64%], hormone, smoking, positive heredo-genetic history, rural residence area, abnormal birth weight, and menstruation disorders showed an increased gonadal malignancy risk; relative risk ratio (RR): 1.33, 1.30, 1.34, 1.11, 1.65, 1.16, 1.36, 1.10, 1.00, 1.08 and 1.15 folds, respectively. RR for histopathological subtypes: immature teratoma (IT) (pollution - 1.75, Rhesus positive - 3.41), dysgerminoma (menstruation disorders - 2.80), granulosa cell tumor (stress - 2.10, menstruation disorders - 2.80), mucinous cystadenomas (obesity - 2.84, no postnatal vaccine - 3.71), mature teratomas (stress - 2.35, malformations - 2.18) and serous cystadenomas (breastfeeding ≤5 months - 2.53), dependent variables being mixed germ cell tumors (GCTs) and cysts. Children presenting with bleeding (73%), abdominal distention (62%), elevated tumor markers (91%), (multilocular) solid tumor (88% and 100%), tumor size >10 cm (65%), GCTs (74%), death (100%), metastases (100%), viruses (77%), loss of appetite (68%), and weight (85%), had gonadal malignant tumors, especially mixed GCTs and IT. CONCLUSIONS Avoiding these risk factors will prevent and reduce gonadal pediatric tumors. Investigating children presenting with the listed peculiarities, especially if exposed to the mentioned risk factors, will enable early gonadal tumor identification, successful patient management, and favorable prognosis.

Abstract
INTRODUCTION Building on previous suboptimal survival results, we aimed to perform a study of the epidemiological status, management, and outcomes of germ cell tumors (GCT) in the Portuguese population. MATERIALS AND METHODS Retrospective populational study of GCT cases diagnosed between 2008 and 2012 in southern Portugal. Joinpoint regression was used to compute average annual percentage change (AAPC) in incidence rate. ESMO/EAU guidelines served as references to evaluate compliance. Association between compliance with guidelines and hospital GCT case load was performed by generalized estimating equation. Survival was calculated by Kaplan-Meier and prognostic factors by Cox models. RESULTS The study included 401 GCT male cases. The AAPC was 5.4% (IC 95% 3.3-7.4, P < .001) from 1999 (an earlier cohort published) to 2012. The median time to diagnosis was 63 days (Q25 = 33 days; Q75 = 114 days; IQR = 81 days). For stage II/III the median time to start chemotherapy was 34 days (Q25 = 22 days; Q75 = 56 days; IQR = 22 days). In 86% cases there was noncompliance with guidelines for the orchiectomy report, 6% for staging, 38% for tumor markers evaluation, 20% for treatment and 25% for chemotherapy dose intensity. The 5-year overall survival was 93.8% (95% CI, 91.3%-96.4%). Hospitals that managed ≤ 3 GCT cases/ year had higher odds for noncompliance with guidelines of blood markers, treatment and dose intensity. None of GCT healthcare access and management factors studied were associated with prognosis. CONCLUSIONS The burden of GCT is rising in Portugal. Although survival has improved, efforts must be made to nationally enhance training and expertise in GCT and support region adapted models of centralization of care.

Sonoelastography for Testicular Tumor Identification: A Systematic Review and Meta-Analysis of Diagnostic Test Accuracy. Cancers (Basel) 2023; 15:3770. [PMID: 37568585 PMCID: PMC10417060 DOI: 10.3390/cancers15153770] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 07/18/2023] [Accepted: 07/21/2023] [Indexed: 08/13/2023] Open
Abstract
The objective of this review was to summarize the applications of sonoelastography in testicular tumor identification and inquire about their test performances. Two authors independently searched English journal articles and full conference papers from CINAHL, Embase, IEEE Xplore®, PubMed, Scopus, and Web of Science from inception and organized them into a PIRO (patient, index test, reference test, outcome) framework. Eleven studies (n = 11) were eligible for data synthesis, nine of which (n = 9) utilized strain elastography and two (n = 2) employed shear-wave elastography. Meta-analyses were performed on the distinction between neoplasm (tumor) and non-neoplasm (non-tumor) from four study arms and between malignancy and benignity from seven study arms. The pooled sensitivity of classifying malignancy and benignity was 86.0% (95%CI, 79.7% to 90.6%). There was substantial heterogeneity in the classification of neoplasm and non-neoplasm and in the specificity of classifying malignancy and benignity, which could not be addressed by the subgroup analysis of sonoelastography techniques. Heterogeneity might be associated with the high risk of bias and applicability concern, including a wide spectrum of testicular pathologies and verification bias in the reference tests. Key technical obstacles in the index test were manual compression in strain elastography, qualitative observation of non-standardized color codes, and locating the Regions of Interest (ROI), in addition to decisions in feature extractions. Future research may focus on multiparametric sonoelastography using deep learning models and ensemble learning. A decision model on the benefits-risks of surgical exploration (reference test) could also be developed to direct the test-and-treat strategy for testicular tumors.

[PMID: 37230752 PMCID: PMC10314033 DOI: 10.1136/oemed-2022-108601] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Accepted: 05/04/2023] [Indexed: 05/27/2023]
Abstract
OBJECTIVE Testicular germ cell tumours (TGCT) are the most common cancer in men of working age and its incidence has increased notably over the past 40 years. Several occupations have been identified as potentially associated with TGCT risk. The aim of this study was to further explore the relationship between occupations, industries and TGCT risk in men aged 18-45 years. METHODS The TESTIS study is a multicenter case-control study conducted between January 2015 and April 2018 in 20 of 23 university hospital centers in metropolitan France. A total of 454 TGCT cases and 670 controls were included. Full job histories were collected. Occupations were coded according to the International Standard Classification of Occupation 1968 version (ISCO-1968) and industry according to the 1999 version of Nomenclature d'Activités Française (NAF-1999). For each job held, ORs and 95% CIs were estimated using conditional logistic regression. RESULTS A positive association was observed between TGCT and occupation as agricultural, animal husbandry worker (ISCO: 6-2; OR 1.71; 95% CI (1.02 to 2.82)), as well as salesman (ISCO: 4-51; OR 1.84; 95% CI (1.20 to 2.82)). An increased risk was further observed among electrical fitters and related, electrical and electronics workers employed for 2 years or more (ISCO: 8-5; OR≥2 years 1.83; 95% CI (1.01 to 3.32)). Analyses by industry supported these findings. CONCLUSIONS Our findings suggest that agricultural, electrical and electronics workers, and salesmen workers experience an increased risk of TGCT. Further research is needed to identify the agents or chemicals in these high-risk occupations which are relevant in the TGCT development. TRIAL REGISTRATION NUMBER NCT02109926.

Akcali K, Tastan S. The effects of flipped classroom model on knowledge, behaviour and health beliefs on testicular cancer and self-examination: a randomized controlled trial study. HEALTH EDUCATION RESEARCH 2023; 38:230-240. [PMID: 36843567 PMCID: PMC10655630 DOI: 10.1093/her/cyad007] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Revised: 01/17/2023] [Accepted: 01/31/2023] [Indexed: 05/24/2023]
Abstract
This randomized controlled trial study aims to examine the flipped classroom model's effects on the knowledge and health beliefs of testicular cancer and testicular self-examination. The study was conducted on 66 students in Northern Cyprus. A descriptive information form, Champion's Health Belief Model Scale, visual analogue scale of satisfaction with the learning method, the knowledge questionnaire on testicular cancer and the testicular self-examination itself were used for data collection. The mean posttest knowledge score of the intervention group (14.44) was higher than the mean posttest knowledge score of the control group (12.65). The difference between groups was statistically significant (P < 0.05). The mean posttest scores obtained by the intervention group from the barriers and the severity subscales of the Champion's Health Belief Model Scale were lower than for the control group (P < 0.05). The percentages of participants performing the testicular self-examination after receiving training were 82.4% and 59.4% for the intervention group and control group, respectively. The complete trial protocol can be accessed at ClinicalTrials.gov (NCT04851197). Since the flipped classroom model increased the rate of students performing testicular self-exams and the levels of knowledge and satisfaction of the students, the use of this model in different courses may be promoted.

FRONTIERS IN RADIOLOGY 2023; 3:1141499. [PMID: 37492385 PMCID: PMC10365019 DOI: 10.3389/fradi.2023.1141499] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Accepted: 03/27/2023] [Indexed: 07/27/2023]
Abstract
The aim of this systematic review was to evaluate the state of the art of radiomics in testicular imaging by assessing the quality of radiomic workflow using the Radiomics Quality Score (RQS) and the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2). A systematic literature search was performed to find potentially relevant articles on the applications of radiomics in testicular imaging, and 6 final articles were extracted. The mean RQS was 11,33 ± 3,88 resulting in a percentage of 31,48% ± 10,78%. Regarding QUADAS-2 criteria, no relevant biases were found in the included papers in the patient selection, index test, reference standard criteria and flow-and-timing domain. In conclusion, despite the publication of promising studies, radiomic research on testicular imaging is in its very beginning and still hindered by methodological limitations, and the potential applications of radiomics for this field are still largely unexplored.

Abstract
The systemic immune-inflammation index (SIII) is a marker studied in multiple types of urologic cancer. This systematic review evaluates the association between SIII values with overall survival (OS) and progression-free survival (PFS) in testicular cancer. We searched observational studies in five databases. The quantitative synthesis was performed using a random-effects model. The risk of bias was assessed using the Newcastle-Ottawa Scale (NOS). The only measure of the effect was the hazard ratio (HR). A sensitivity analysis was performed according to the risk of bias in the studies. There were 833 participants in a total of 6 cohorts. We found that high SIII values were associated with worse OS (HR = 3.28; 95% CI 1.3-8.9; p < 0.001; I2 = 78) and PFS (HR = 3.9; 95% CI 2.53-6.02; p < 0.001; I2 = 0). No indication of small study effects was found in the association between SIII values and OS (p = 0.5301). High SIII values were associated with worse OS and PFS. However, further primary studies are suggested to enhance the effect of this marker in different outcomes of testicular cancer patients.

Integrated Microarray-Based Data Analysis of miRNA Expression Profiles: Identification of Novel Biomarkers of Cisplatin-Resistance in Testicular Germ Cell Tumours. Int J Mol Sci 2023; 24:ijms24032495. [PMID: 36768818 PMCID: PMC9916636 DOI: 10.3390/ijms24032495] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 01/13/2023] [Accepted: 01/25/2023] [Indexed: 01/31/2023] Open
Abstract
Testicular germ cell tumours (TGCTs) are the most common solid malignancy among young men, and their incidence is still increasing. Despite good curability with cisplatin (CDDP)-based chemotherapy, about 10% of TGCTs are non-responsive and show a chemoresistant phenotype. To further increase TGCT curability, better prediction of risk of relapse and early detection of refractory cases is needed. Therefore, to diagnose this malignancy more precisely, stratify patients more accurately and improve decision-making on treatment modality, new biomarkers are still required. Numerous studies showed association of differential expressions of microRNAs (miRNAs) with cancer. Using microarray analysis followed by RT-qPCR validation, we identified specific miRNA expression patterns that discriminate chemoresistant phenotypes in TGCTs. Comparing CDDP-resistant vs. -sensitive TGCT cell lines, we identified miR-218-5p, miR-31-5p, miR-125b-5p, miR-27b-3p, miR-199a-5p, miR-214-3p, let-7a and miR-517a-3p as significantly up-regulated and miR-374b-5p, miR-378a-3p, miR-20b-5p and miR-30e-3p as significantly down-regulated. In patient tumour samples, we observed the highest median values of relative expression of miR-218-5p, miR-31-5p, miR-375-5p and miR-517a-3p, but also miR-20b-5p and miR-378a-3p, in metastatic tumour samples when compared with primary tumour or control samples. In TGCT patient plasma samples, we detected increased expression of miR-218-5p, miR-31-5p, miR-517a-3p and miR-375-5p when compared to healthy individuals. We propose that miR-218-5p, miR-31-5p, miR-375-5p, miR-517-3p, miR-20b-5p and miR-378a-3p represent a new panel of biomarkers for better prediction of chemoresistance and more aggressive phenotypes potentially underlying metastatic spread in non-seminomatous TGCTs. In addition, we provide predictions of the targets and functional and regulatory networks of selected miRNAs.

Abstract
Background PIWI-interacting RNAs (piRNAs) are a class of noncoding RNAs originally reported in the reproductive system of mammals and later found to be aberrantly expressed in tumors. However, the function and mechanism of piRNAs in testicular cancer are not very clear. Methods The expression level and distribution of piR-36249 were detected by RT-qPCR and immunofluorescence staining assay. Testicular cancer cell (NT2) progression was measured by CCK8 assay, colony formation assay and wound healing assay. Cell apoptosis was assessed by flow cytometry and western blot. RNA sequencing and dual-luciferase reporter assay were conducted to identify the potential targets of piR-36249. The relationship between piR-36249 and OAS2 or DHX36 was confirmed using overexpression assay, knockdown assay, pull-down assay and RIP assay. Results piR-36249 is significantly downregulated in testicular cancer tissues compared to tumor-adjacent tissues. Functional studies demonstrate that piR-36249 inhibits testicular cancer cell proliferation, migration and activates the cell apoptosis pathway. Mechanically, we identify that piR-36249 binds to the 3'UTR of 2'-5'-oligoadenylate synthetase 2 (OAS2) mRNA. OAS2 has been shown in the literature to be a tumor suppressor modulating the occurrence and development of some tumors. Here, we show that OAS2 knockdown also promotes testicular cancer cell proliferation and migration. Furthermore, piR-36249 interacts with DHX36, which has been reported to promote translation. DHX36 can also bind to OAS2 mRNA, and knockdown of DHX36 increases OAS2 mRNA but downregulates its protein, indicating the enhancing effect of DHX36 on OAS2 protein expression. Conclusion All these data suggest that piR-36249, together with DHX36, functions in inhibiting the malignant phenotype of testicular cancer cells by upregulating OAS2 protein and that piR-36249 may be used as a suppressor factor to regulate the development of testicular cancer.

Abstract
Urological tumours have become one of the most common cancers in the
last decade. It is important to apply an approach that evaluates many factors related to
the patient and the disease carefully to minimize cancer-associated morbidity and
mortality. The clinical use of cancer biomarkers is a valuable part of the clinical
management of urological cancers. These biomarkers may lead to optimized detection,
treatment, and follow-up of urological cancers. With the development of molecular
research, newly developed biomarkers and next-generation sequencing have also
contributed to patient management. In this chapter, we will present biomarkers in the
most common urological cancers under subheadings of bladder cancer, prostate cancer,
kidney cancer, and testicular cancer. Additionally, due to the development that
occurred in the next-generation sequencing (NGS), all the above-mentioned
malignancies are evaluated with regard to NGS.

Activation of estrogen receptor ESR1 and ESR2 induces proliferation of the human testicular embryonal carcinoma NT2/D1 cells. Mol Cell Endocrinol 2022; 554:111708.

Abstract
The aims of the present study were to investigate the expression of the classic estrogen receptors ESR1 and ESR2, the splicing variant ESR1-36 and GPER in human testicular embryonal carcinoma NT2/D1 cells, and the effects of the activation of the ESR1 and ESR2 on cell proliferation. Immunostaining of ESR1, ESR2, and GPER were predominantly found in the nuclei, and less abundant in the cytoplasm. ESR1-36 isoform was predominantly expressed in the perinuclear region and cytoplasm, and some weakly immunostained in the nuclei. In nonstimulated NT2/D1 cells (control), proteins of the cell cycle CCND1, CCND2, CCNE1 and CDKN1B are present. Activation of ESR1 and ESR2 increases, respectively, CCND2 and CCNE1 expression, but not CCND1. Activation of ESR2 also mediates upregulation of the cell cycle inhibitor CDKN1B. This protein co-immunoprecipitated with CCND2. Also, E2 induces an increase in the number and viability of the NT2/D1 cells. These effects are blocked by simultaneous pretreatment with ESR1-and ESR2-selective antagonists, confirming that both estrogen receptors regulate NT2/D1 cell proliferation. In addition, E2 increases SRC phosphorylation, and SRC mediates cell proliferation. Our study provides novel insights into the signatures and molecular mechanisms of estrogen receptor in NT2/D1 cells.

[PMID: 36011006 PMCID: PMC9406361 DOI: 10.3390/cancers14164013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 08/09/2022] [Accepted: 08/10/2022] [Indexed: 12/04/2022] Open
Abstract
The spontaneous regression of testicular germ-cell tumours is a rare event whose mechanisms have yet to be elucidated. In the majority of published cases, tumour regression is concomitant with the metastatic development of the disease. Residual lesions, often referred to as burned-out testicular tumours (BOTTs), are difficult to diagnose due to the paucity of published data, especially in the field of imaging. The aim of this article is to describe the radiological signs of BOTTs on multimodal ultrasound and multiparametric MRI from a series of 48 patients whose diagnosis was confirmed histologically. The demographic, clinical and laboratory characteristics of the patients are studied, as well as the data of the imaging examinations, including conventional scrotal ultrasound, shear-wave elastography, contrast-enhanced ultrasound (CEUS) and multiparametric MRI. A total of 27 out of 48 patients were referred for investigation of primary testicular lesion following the discovery of retroperitoneal metastases, 18/48 patients were referred because of lesions suspected on an ultrasound that was performed for an infertility work-up, and 3/48 were referred because of scrotal clinical signs. Of these last 21 patients (infertility work-up/scrotal clinical sign), 6 were found to be metastatic on the extension work-up. Of the 48 orchiectomy specimens, tumour involution was complete in 41 cases, and a small active contingent remained in 7 cases, with 6 suspected upon advanced US and MRI. Typically, BOTTs appear on a conventional ultrasound as ill-delineated, hypoechoic and hypovascular nodular areas. Clustered microliths (60.4%) and macrocalcifications (35.4%) were frequent. Shear-wave elastography showed areas of focal induration (13.5 ± 8.4 vs. 2.7 ± 1.2 kPa for normal parenchyma, p < 0.01) in 92.5% of the patients for whom it was performed, and contrast ultrasonography demonstrated hypoperfusion of these lesions. Of the 42 MRIs performed, BOTTs corresponded to nodules on T2-weighted sequences (hyposignal) with significantly increased ADC values compared with healthy parenchyma (2 ± 0.3 versus 1.3 ± 0.3 × 10−3 mm2/s, p < 0.01) and an enhancement defect after injection. This enhancement defect overlapped the lesions visible on T2-weighted sequences in most cases. In the case of predominant partial regression, an enhanced portion after contrast injection was visible on MRI in all seven patients of our series, and in six of them a focal diffusion restriction zone was also present. Spontaneously involuted testicular germ-cell tumours have specific radiological signs, and all of the mentioned examinations contribute to this difficult diagnosis, even histologically, because there is no tumour cell left. These signs are similar whether the patient is initially symptomatic metastatic or whether the discovery is fortuitous on the occasion of an infertility work-up, and whatever the seminomatous or non-seminomatous nature of the germ-cell tumour, when this can be determined. The appearance of regressed germ-cell tumours is often trivialized, which can lead to the wrong diagnosis of an extra gonadal germ-cell tumour (in metastatic patients) or of scarring from an acute event such as trauma or infection, which is not recognized or forgotten. In our series, two patients had an unrecognized diagnosis in their history, with local and/or distant recurrence. An improvement in diagnosing burned-out tumours, combining advanced US and MRI, is necessary in order to optimize patient management, with special attention paid to asymptomatic patients, to prompt extension screening and orchiectomy with analysis of the whole testis. This may reveal a persistent viable tumour or lesions of germinal neoplasia in situ, which are precursors of testicular germ-cell tumours.

Endocrine-disrupting chemicals affect sertoli TM4 cell functionality through dysregulation of gap junctional intercellular communication in vitro. Food Chem Toxicol 2022; 164:113004.

Abstract
The frequencies of adverse outcomes associated with male reproductive health, including infertility and testicular cancer, are increasing. These adverse trends are partially attributed to increased exposure to environmental agents such as endocrine-disrupting chemicals (EDCs). This study addresses effects on EDCs on adjacent prepubertal Sertoli TM4 cells, specifically on 1) testicular gap junctional intercellular communication (GJIC), one of the hallmarks of non-genotoxic carcinogenicity, 2) GJIC building blocks connexins (Cx), and 3) mitogen-activated protein kinases MAPKs. We selected eight representatives of EDCs: bisphenol A and organochlorine chemicals such as pesticides dichlorodiphenyltrichloroethane, lindane, methoxychlor, and vinclozolin, industrial chemical 2,2',4,4',5,5'-hexachlorobiphenyl, and components of personal care products, triclocarban and triclosan. EDCs rapidly dysregulated GJIC in Sertoli TM4 cells mainly via MAPK p38 and/or Erk1/2/pathways by the intermediate hyper- or de-phosphorylation of Cx43 (Ser368, Ser282) and translocalization of Cx43 from the plasma membrane, suggesting disturbed intracellular trafficking of Cx43 protein. Surprisingly, EDCs did not rapidly activate MAPK Erk1/2 or p38; on the contrary, TCC and TCS decreased their activity (phosphorylation). Our results indicate that EDCs might disrupt testicular homeostasis and development via testicular GJIC, junctional and non-junctional functions of Cx43 and MAPK-signalling pathways in Sertoli cells.

NPS-1034 Induce Cell Death with Suppression of TNFR1/NF-κB Signaling in Testicular Cancer. Medicina (B Aires) 2022; 58:medicina58030355.

Abstract
Background and objectives: NPS-1034 with a dual inhibitory effect on Met and Axl kinase receptors has exhibited therapeutic potential in previous models. However, no study on treating testicular cancer (TC) cell lines with NPS-1034 has been established. Materials and Methods: In this study, a series of in vitro examinations of the apoptotic effect induced by NPS-1034 in TC cell lines was conducted to clarify the molecular interactions involved. Results: A decrease in cell viability rate was observed following NPS-1034 treatment, as shown in the MTT assay. Induction of the apoptotic effect was observed in TC cells as the sub-G1 and Annexin-PI populations increased in a dose-dependent manner. The involvement of the tumor receptor necrosis factor receptor 1 (TNFR1) pathway was later determined by the proteome array and western blotting. A reduction in TNFR1 and NF-κB downstream protein expressions, an upregulation of cleaved caspase-3 and -7, and a downregulation of survivin and claspin all reassured the underlying mechanism of the TNFR1 involved in the apoptotic pathway induced by NPS-1034. Conclusions: Our findings provide evidence for a potential underlying TNFR1 pathway involved in NPS-1034 treatment. This study should offer new insights into targeted therapy for TC.

Abstract
The incidence of many hormone-dependent diseases, including testicular cancer, has sharply increased in all high-income countries during the 20th century. This is not fully explained by established risk factors. Concurrent, increasing exposure to antiandrogenic environmental endocrine disrupting chemicals (EDCs) in fetal life may partially explain this trend. This systematic review assessed available evidence regarding the association between environmental EDC exposure and risk of testicular cancer (seminomas and nonseminomas). Following PRISMA guidelines, a search of English peer-reviewed literature published prior to December 14, 2020 in the databases PubMed and Embase® was performed. Among the 279 identified records, 19 were eligible for quality assessment and 10 for further meta-analysis. The completeness of reporting was high across papers, but over 50% were considered subject to potential risk of bias. Mean age at diagnosis was 31.9 years. None considered effects of EDC multipollutant mixtures. The meta-analyses showed that maternal exposure to combined EDCs was associated with a higher risk of testicular cancer in male offspring [summary risk ratios: 2.16, (95% CI:1.78-2.62), 1.93 (95% CI:1.49-2.48), and 2.78 (95% CI:2.27-3.41) for all, seminoma, and nonseminoma, respectively]. Similarly, high maternal exposures to grouped organochlorines and organohalogens were associated with higher risk of seminoma and nonseminoma in the offspring. Summary estimates related to postnatal adult male EDC exposures were inconsistent. Maternal, but not postnatal adult male, EDC exposures were consistently associated with a higher risk of testicular cancer, particularly risk of nonseminomas. However, the quality of studies was mixed, and considering the fields complexity, more prospective studies of prenatal EDC multipollutant mixture exposures and testicular cancer are needed.

Abstract
BACKGROUND Male reproductive development in mammals can be divided into a gonadal formation phase followed by a hormone-driven differentiation phase. Failure of these processes may result in Differences in Sex Development (DSD), which may include abnormalities of the male reproductive tract, including cryptorchidism, hypospadias, infertility, and testicular germ cell cancer (TGCC). These disorders are also considered to be part of a testicular dysgenesis syndrome (TDS) in males. Whilst DSDs are considered to result primarily from genetic abnormalities, the development of TDS disorders is frequently associated with environmental factors. SUMMARY In this review, we will discuss the development of the male reproductive system in relation to DSD and TDS. We will also describe the experimental systems, including studies involving animals and human tissues or cells that can be used to investigate the role of environmental factors in inducing male reproductive disorders. We will discuss recent studies investigating the impact of environmental chemicals (e.g., phthalates and bisphenols), lifestyle factors (e.g., smoking) and pharmaceuticals (e.g., analgesics) on foetal testis development. Finally, we will describe the evidence, involving experimental and epidemiologic approaches, for a role of environmental factors in the development of specific male reproductive disorders, including cryptorchidism, hypospadias, and TGCC. Key Messages: Environmental exposures can impact the development and function of the male reproductive system in humans. Epidemiology studies and experimental approaches using human tissues are important to translate findings from animal studies and account for species differences in response to environmental exposures.

Abstract
Testicular germ cell tumors (TGCTs) are highly prevalent in young men aged 20–40
years and are one of the most common lethal solid tumors in men of this age. Due
to the current unclear mechanism of tumor development, there is a lack of
effective treatment, and therefore in-depth research of the molecular mechanism
of the occurrence and development of TGCT and the search for suitable and
effective therapeutic targets and molecular markers are of great significance
for achieving effective treatment. METTL3 is a very important methylase, which
has been implicated in the progression of many cancers, but the role of METTL3
in TGCT has not been fully elucidated. In this article, we found that METTL3
expression was significantly downregulated in TGCT tissues, and patients with
low expression levels had lower overall survival and relapse-free survival
rates. After overexpressing METTL3, cell proliferation, invasion, and migration
ability significantly increased, while influencing the expression of
epithelial–mesenchymal transition (EMT)-related proteins. In addition, we
observed that the expression level of METTL3 positively correlated with
molecular markers and infiltration level of CD8+ and CD4+ T cells and natural
killer cells. In sum, our findings identified that METTL3 can be used as an
independent prognostic marker in patients with TGCT. METTL3 participates in the
proliferation, migration, and invasion of TGCT cells by regulating the
expression of EMT-related genes and may also play a role in activating the tumor
immune response in TGCT.

Overexpression of p75 NTR in Human Seminoma: A New Biomarker? Life (Basel) 2021; 11:629.

Abstract
Several studies have demonstrated that the p75NTR low-affinity receptor of Nerve Growth Factor (NGF), is produced in abnormally large amounts in several human cancer types. However, the role of p75NTR varies substantially depending on cell context, so that a dual role of this receptor protein in tumor cell survival and invasion, as well as cell death, has been supported in recent studies. Herein we explored for the first time the expression of p75NTR in human specimens (nr = 40) from testicular germ cell tumors (TGCTs), mostly seminomas. Nuclear overexpression of p75NTR was detected by immunohistochemistry in seminoma tissue as compared to normal tissue, whereas neither NGF nor its high-affinity TrkA receptor was detected. An increased nuclear staining of phospho-JNK, belonging to the p75NTR signaling pathway and its pro-apoptotic target gene, p53, was concomitantly observed. Interestingly, our analysis revealed that decreased expression frequency of p75NTR, p-JNK and p53 was related to staging progression, thus suggesting that p75NTR may represent a specific marker for seminoma and staging in TGCTs.

Abstract
Male sex determination and sexual differentiation occur between 6-12 weeks of gestation. During the "male programming window" the fetal testes start to produce testosterone that initiates the development of the male reproductive tract. Exposure to endocrine disrupting chemicals (EDCs) able to mimic or disrupt steroid hormone actions may disrupt testicular development and adversely impact reproductive health at birth, during puberty and adulthood. The testicular dysgenesis syndrome (TDS) occurs as a result inhibition of androgen action on fetal development preceding Sertoli and Leydig cell dysfunction and may result from direct or epigenetic effects. Hypospadias, cryptorchidism and poor semen quality are elements of TDS, which may be considered a risk factor for testicular germ cell cancer (TGCC). Exposure to estrogen or estrogenic EDCs results in developmental estrogenization/estrogen imprinting in the rodent for prostate cancer (PCa). This can disrupt prostate histology by disorganization of the epithelium, prostatic intraepithelial neoplasia (PIN) lesions, in particular high-grade PIN (HGPIN) lesions which are precursors of prostatic adenocarcinoma. These defects persist throughout the lifespan of the animal and later in life estrogen exposure predispose development of cancer. Exposure of pregnant dams to vinclozolin, a competitive anti-androgen, and results in prominent, focal regions of inflammation in all exposed animals. The inflammation closely resembles human nonbacterial prostatitis that occurs in young men and evidence indicates that inflammation plays a central role in the development of PCa. In conclusion, in utero exposure to endocrine disrupters may predispose to the development of TDS, testicular cancer (TCa) and PCa and are illustrations of Developmental Origins of Health and Disease (DOHaD).

Abstract
The broad-spectrum herbicide, glyphosate, is considered safe for animals because it selectively affects the shikimate pathway that is specific to plants and microorganisms. We sought a previously unknown mechanism to explain the concerns that glyphosate exposure can negatively affect animals, including humans. Computer modeling showed a probable interaction between glyphosate and eukaryotic translation elongation factor 1 subunit alpha 1 (eEF1α1), which was confirmed by microcalorimetry. Only restricted, nondisrupted spermatogenesis in rats was observed after chronic glyphosate treatments (0.7 and 7 mg/L). Cytostatic and antiproliferative effects of glyphosate in GC-1 and SUP-B15 cells were indicated. Meta-analysis of public health data suggested a possible effect of glyphosate use on sperm count. The in silico, in vitro, and in vivo experimental results as well as the metastatistics indicate side effects of chronic glyphosate exposure. Together, these findings indicate that glyphosate delays protein synthesis through an interaction with eEF1α1, thereby suppressing spermatogenesis and cell growth.

Tarapore P, Ouyang B. Perfluoroalkyl Chemicals and Male Reproductive Health: Do PFOA and PFOS Increase Risk for Male Infertility? INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18073794. [PMID: 33916482 PMCID: PMC8038605 DOI: 10.3390/ijerph18073794] [Citation(s) in RCA: 54] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 03/18/2021] [Accepted: 03/23/2021] [Indexed: 01/09/2023]
Abstract
Poly- and perfluoroalkyl substances (PFAS) are manmade synthetic chemicals which have been in existence for over 70 years. Though they are currently being phased out, their persistence in the environment is widespread. There is increasing evidence linking PFAS exposure to health effects, an issue of concern since PFAS such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) bioaccumulate in humans, with a half-life of years. Many epidemiological studies suggest that, worldwide, semen quality has decreased over the past several decades. One of the most worrying effects of PFOS and PFOA is their associations with lower testosterone levels, similar to clinical observations in infertile men. This review thus focuses on PFOS/PFOA-associated effects on male reproductive health. The sources of PFAS in drinking water are listed. The current epidemiological studies linking increased exposure to PFAS with lowered testosterone and semen quality, and evidence from rodent studies supporting their function as endocrine disruptors on the reproductive system, exhibiting non-monotonic dose responses, are noted. Finally, their mechanisms of action and possible toxic effects on the Leydig, Sertoli, and germ cells are discussed. Future research efforts must consider utilizing better human model systems for exposure, using more accurate PFAS exposure susceptibility windows, and improvements in statistical modeling of data to account for the endocrine disruptor properties of PFAS.

Environmental chemicals in dog testes reflect their geographical source and may be associated with altered pathology. Sci Rep 2021; 11:7361.

Abstract
In humans and dogs, a temporal decline in semen quality and increased incidence of testicular cancer is hypothesised to be associated with exposure to anthropogenic chemicals, particularly during fetal development. Human studies suggest that differential exposures to environmental chemicals may be associated with geographical differences in male reproductive health. Here we investigate testicular chemical profiles and pathologies in dogs residing in the UK [West Midlands (WM), East Midlands (EM), South East (SE)], Denmark (Copenhagen) and Finland (Vantaa). Testes, surplus from routine castrations, contained region specific differences in relative concentrations of diethylhexyl phthalate (DEHP), polybrominated diphenyl ethers (PBDE) and polychlorinated biphenyls (PCB). Relative to UK regions, testes from dogs living in Finland and Denmark had higher concentrations of PBDE and lower concentrations of DEHP and PCBs. Regional differences in the UK in PCB concentrations were also observed. Dog testes from Finland had fewer pathologies, reduced testicular area stained for Sertoli and germ cells and evidence of reduced cellular proliferation. Since the geographical differences in testis pathologies in dogs parallel reports of regional differences in human testicular cancer, we postulate that this may reflect chemical effects within the testis and that this may be related to environmental influences on male reproductive function.

Abstract
Primordial germ cells (PGCs) are common ancestors of all germline cells. In mammals, PGCs emerge in early-stage embryos around the timing of gastrulation at or near epiblast, and specification of PGCs from their precursor cells involves multiple growth factors secreted by adjacent cells. Recent advancements in germline stem cell biology have made it possible to generate PGC-like cell culture models (PGCLCs for PGC-like cells) from human and mouse pluripotent stem cells by mimicking the embryonic growth factor environment in vitro. Here we describe a method of producing human PGCLCs from primed-pluripotency induced pluripotent stem cells (iPSCs) via temporal conversion to naive pluripotency followed by formation of embryoid bodies (EBs) using the spin-EB method.

Abstract
Germ cell cancers are the most common solid tumors among men between 15 and 40 years. Non-seminomatous germ cell tumors (NSGCTs) represent a unique and exclusive cohort of germ cell tumor patients. Non-seminoma can harbor different histologic components. The most commonly found histologies are embryonal cell cancer, teratoma, yolk sack tumor and choriocarcinoma, as well as teratocarcinoma and seminoma, in combination with non-seminomatous germ cell tumors histologic types. The clinical definition of stage I non-seminoma is the absence of metastatic lesions on imaging and normal tumor markers. The cure rate for clinical stage I NSGCT is 99% and this can be achieved by three therapeutic strategies: Active surveillance with treatment at the time of relapse, retroperitoneal lymph node dissection or adjuvant chemotherapy. The balancing of these various strategies should always be based on an individual risk profile of NGSCG patient depending on the lymphovascular invasion of the tumor.

Abstract
AIM The objective of this study is to present the history of cancers of the external genital organs of male in Hérault using data from the Hérault tumor register (RTH) over a period of 30 years. PATIENTS AND METHODS Using the RTH database, we studied the development of testicular germ cell tumors (TGCT) and penile cancer (PC) over 30 years, from 1987 to 2016. We analyzed the incidence and mortality data for these tumors. We compared these results to French, European and global data. RESULTS In 30 years of registration we have recorded 725 cases of TGCT and 175 cases of PC. The age standardized incidence rate (ASR) of TGCT has doubled between 1987 and 2016 (4.2 per 100,000 in 1987 and 9.3 per 100,000 in 2016). It was multiplied by 2.63 in the population of patients aged 30 to 44. There is a decrease of the mortality rate with a ASR of 0.8 deaths per 100,000 in 1987, and 0.4/100 000 in 2016. The PC incidence ASR was stable between 1987 and 2016 (0.4-0.9/100,000). Mortality is stable with a ASR between 0.1 and 0.3 deaths per 100,000 between 1987 and 2016. CONCLUSION The incidence of TGCT has increased sharply in the Hérault over the past 30 years, while a decrease in mortality has been observed. The proportion of seminomas is increasing; it has gone from 53 % to 60 % in 30 years in the Hérault. The incidence and mortality of PC shows a stability in the Hérault over the past 30 years.

Abstract
Disruption of element homeostasis may contribute to increased susceptibility of men to cancer development. Whether environmental low-level metal exposure could contribute to the pathogenesis of testicular cancer is unknown. Comparison of the level of 18 elements in whole blood, serum and urine and parameters of oxidative stress/antioxidant status between men with testicular germ cell tumors (TGCT) and healthy men showed significant difference between the groups in most parameters. The results of linear discriminant analysis with a discrimination rate of 96% indicated whole blood Ca, Co, Cu, Fe, K, Mg, Na and Zn, serum Ca, Cu, Na and Ni, and urine Cd, Co, Fe and Mn being the strongest predictors of illness. TGCT patients had a significant increase in serum and blood Cu and decrease in serum Fe and blood Zn with cancer progression. Significantly higher concentrations of Al, As, Pb, and Ni in whole blood/serum of men with TGCT confirm the hypothesis that low-level environmental exposure to these elements may contribute to cancer development. Relationship between elements concentrations and treatment outcomes should be carefully monitored during cancer treatment since high concentrations of commonly used platinum-based chemotherapeutics may additionally disturb the homeostasis of elements.

Abstract
Testicular cancer (TC) is the most common form of cancer in men aged 15-35 years. Familial risk for TC is among highest of all cancers. MATERIAL AND METHODS A prospective observational cohort of 9111 relatives in 2,188 families of early-onset TC patients, called probands, diagnosed at age ≤40 years in Finland between 1970 and 2012. Standardized incidence ratios (SIR) were used as measures of familial aggregation for early-onset (≤40 years) TC. Follow-up ended at diagnosis of TC, death or 31 December 2014 whichever earliest. RESULTS Among first-degree relatives of early-onset TCs, in all 12 early-onset TC cases (0.24%) were diagnosed over the follow-up; the SIR for any first-degree relative was 4.59 (95% confidence interval (CI): 2.37-8.01) and for brothers the SIR was 6.51 (95% CI 3.12-11.96). DISCUSSION Familial aggregation of TC shows substantial risk for early-onset TC among first-degree relatives of early-onset TC patients in Finland. This is important to acknowledge to avoid diagnostic delay especially of TC.

Abstract
Germ-cell testicular cancer (GCTC) is a malignant neoplasm derived from the primordial germ cell. Although it accounts for approximately 1% of all malignancies in men, it is the most common cancer of younger male population, with the highest incidence between ages 15 and 35. Testicular cancer incidence rate has risen globally over the past several decades, with the average increase in the incidence of testicular cancer in Croatia of 7% per annum from the year 1983 to 2007. Two main groups are seminomas and non-seminomas, each accounting for 50% of cases, and they differ in treatment modalities and response to therapy. Despite increase in the incidence rate, a promising circumstance is that GCTC has become a model of curable cancer. Because of advances in diagnostic procedures, sophisticated radiation techniques and especially the introduction of cisplatin based chemotherapy protocols together with advanced postchemotherapy surgical techniques, curability is expected in about 95% of all patients diagnosed with testicular cancer and over 70% of patients with advanced disease. In this review, we will focus on treatment strategies of primary GCTC.

Abstract
Testicular cancer is the most common cancer among young men of European ancestry, with about one-third of all cases occurring in Europe. With the historically increasing trends in some high-incidence populations reported to have stabilised in recent years, we aimed to assess recent trends and predict the future testicular cancer incidence burden across Europe. We extracted testicular cancer (ICD-10 C62) incidence data from Cancer Incidence in Five Continents Volumes VII-XI and complemented this with data published by registries from 28 European countries. We predicted cancer incidence rates and the number of incident cases in Europe in the year 2035 using the NORDPRED age-period-cohort model. Testicular cancer incidence rates will increase in 21 out of 28 countries over the period 2010-2035, with trends attenuating in the high-incidence populations of Denmark, Norway, Switzerland and Austria. Although population ageing would be expected to reduce the number of cases, this demographic effect is outweighed by increasing risk, leading to an overall increase in the number of cases by 2035 in Europe, and by region (21, 13 and 32% in Northern, Western and Eastern Europe, respectively). Declines are however predicted in Italy and Spain, amounting to 12% less cases in 2035 in Southern Europe overall. In conclusion, the burden of testicular cancer incidence in Europe will continue to increase, particularly in historically lower-risk countries. The largest increase in the number of testicular cancer patients is predicted in Eastern Europe, where survival is lower, reinforcing the need to ensure the provision of effective treatment across Europe.

Abstract
Background SPANX family members are thought to play an important role in cancer progression. The SPANXN2 is a gene expressed mainly in normal testis, but its role in testicular germ cell tumors (TGCTs) has yet to be investigated. TGCT is one of the most common solid tumors in young men and is associated with poor prognosis; however, effective prognostic indicators remain elusive. Therefore, we investigated the role of SPANXN2 in TGCT development. Methods SPANXN2 expression levels were validated by quantitative real-time polymerase chain reaction (qRT-PCR) analyses of 14 TGCT samples and five adjacent normal tissue samples. SPANXN2 was transiently overexpressed in TGCT cells to study the consequences for cell function. The effects of SPANXN2 on cell migration were evaluated in transwell and wound healing assays. The effects on cloning ability were evaluated in colony formation assays. MTT assays and cell cycle analysis were used to detect the effects of SPANXN2 on cell proliferation. The expression levels of EMT- and AKT-related proteins in cells overexpressing SPANXN2 were analyzed by Western blotting. Results Compared with adjacent normal tissues, the Gene Expression Profiling Interactive Analysis database showed SPANXN2 expression was downregulated in TGCTs which was consistent with the qRT-PCR analysis. SPANXN2 overexpression reduced cell migration and colony formation capability and downregulated expression of EMT- and AKT-related proteins, Vimentin, Snail, AKT, and p-AKT. Conclusion Our results suggest that SPANXN2 regulates TGCT cell migration via EMT- and AKT-related proteins although its role in the occurrence and development of TGCT remains to be fully elucidated.

Abstract
Germ cell tumour (GCT) patients who fail to respond to chemotherapy or who relapse have a poor prognosis. Timely and accurately stratifying such patients could optimise their therapy. We identified endogenous DNA damage levels as a prognostic marker for progression-free (PFS) and overall (OS) survival in chemotherapy-naïve GCT patients. In the present study, we have extended our previous results and reviewed the prognostic power of DNA damage level in GCTs. Endogenous DNA damage levels were measured with the comet assay. Receiver operator characteristic analysis was applied to determine the optimal cut-off value and to evaluate its prognostic accuracy. PFS and OS were estimated by the Kaplan-Meier method and compared using the log-rank test. Hazard ratio (HR) estimates were calculated by Cox regression analysis. A cut-off value of 6.34 provided the highest sensitivity and specificity, with area under curve values of 0.813 and 0.814 for disease progression and mortality, respectively. A % DNA in tail > 6.34 was significantly associated with shorter PFS (HR = 9.54, 95 % confidence interval [CI]: 3.43-26.55, p < 0.001) and OS (HR = 14.62, 95 % CI: 3.14-67.95, p = 0.001) by univariate analysis. The prognostic value of DNA damage measurement was confirmed by multivariate models (HR = 6.45, 95 % CI: 2.22-18.75, p = 0.001 for PFS and HR = 9.40, 95 % CI: 1.70-52.09, p = 0.010 for OS), when HR was adjusted for relevant clinical categories. The added prognostic value of DNA damage in combination with International Germ Cell Cancer Collaborative Group (IGCCCG) risk groups has been revealed. Endogenous DNA damage is an independent prognosticator for PFS and OS in GCT patients and its clinical use, particularly in combination with IGCCCG risk groups, may help in stratifying these patients.

Abstract
Importance Approximately 50% of the risk for the development of testicular germ cell tumors (TGCTs) is estimated to be heritable, but no mendelian TGCT predisposition genes have yet been identified. It is hypothesized that inherited pathogenic DNA repair gene (DRG) alterations may drive susceptibility to TGCTs. Objective To systematically evaluate the enrichment of germline pathogenic variants in the mendelian cancer predisposition DRGs in patients with TGCTs vs healthy controls. Design, Setting, and Participants A case-control enrichment analysis was performed from January 2016 to May 2018 to screen for 48 DRGs in 205 unselected men with TGCT and 27 173 ancestry-matched cancer-free individuals from the Exome Aggregation Consortium cohort in the discovery stage. Significant findings were selectively replicated in independent cohorts of 448 unselected men with TGCTs and 442 population-matched controls, as well as 231 high-risk men with TGCTs and 3090 ancestry-matched controls. Statistical analysis took place from January to May 2018. Main Outcomes and Measures Gene-level enrichment analysis of germline pathogenic variants in individuals with TGCTs relative to cancer-free controls. Results Among 205 unselected men with TGCTs (mean [SD] age, 33.04 [9.67] years), 22 pathogenic germline DRG variants, one-third of which were in CHEK2 (OMIM 604373), were identified in 20 men (9.8%; 95% CI, 6.1%-14.7%). Unselected men with TGCTs were approximately 4 times more likely to carry germline loss-of-function CHEK2 variants compared with cancer-free individuals from the Exome Aggregation Consortium cohort (odds ratio [OR], 3.87; 95% CI, 1.65-8.86; nominal P = .006; q = 0.018). Similar enrichment was also seen in an independent cohort of 448 unselected Croatian men with TGCTs (mean [SD] age, 31.98 [8.11] years) vs 442 unselected Croatian men without TGCTs (at least 50 years of age at time of sample collection) (OR, >1.4; P = .03) and 231 high-risk men with TGCTs (mean [SD] age, 31.54 [9.24] years) vs 3090 men (all older than 50 years) from the Penn Medicine Biobank (OR, 6.30; 95% CI, 2.34-17.31; P = .001). The low-penetrance CHEK2 variant (p.Ile157Thr) was found to be a Croatian founder TGCT risk variant (OR, 3.93; 95% CI, 1.53-9.95; P = .002). Individuals with the pathogenic CHEK2 loss-of-function variants developed TGCTs 6 years earlier than individuals with CHEK2 wild-type alleles (5.95 years; 95% CI, 1.48-10.42; P = .009). Conclusions and Relevance This multicenter case-control analysis of men with or without TGCTs provides evidence for CHEK2 as a novel moderate-penetrance TGCT susceptibility gene, with potential clinical utility. In addition to highlighting DNA-repair deficiency as a potential mechanism driving TGCT susceptibility, this analysis also provides new avenues to explore management strategies and biological investigations for high-risk individuals.

Abstract
The G protein-coupled estrogen receptor (GPER), also known as GPR30, is a widely conserved 7-transmembrane-domain protein which has been identified as a novel 17β-estradiol-binding protein that is structurally distinct from the classic oestrogen receptors (ERα and ERβ). There are still conflicting data regarding the exact role and the natural ligand of GPER/GPR30 in reproductive tracts as both male and female knock-out mice are fertile and have no abnormalities of reproductive organs. Testicular germ cell cancers (TGCCs) are the most common malignancy in young males and the most frequent cause of death from solid tumors in this age group. Clinical and experimental studies suggested that estrogens participate in the physiological and pathological control of male germ cell proliferation. In human seminoma cell line, while 17β-estradiol (E2) inhibits in vitro cell proliferation through an ERβ-dependent mechanism, an impermeable E2 conjugate (E2 coupled to BSA), in vitro cell proliferation is stimulated by activating ERK1/2 and protein kinase A through a membrane GPCR that we further identified as GPER/GPR30. The same effect was observed with low but environmentally relevant doses of BPA, an estrogenic endocrine disrupting compound. Furthermore, GPER/GPR30 is specifically overexpressed in seminomas but not in non-seminomas and this overexpression is correlated with an ERβ-downregulation. This GPER/GPR30 overexpression could be linked to some genetic variations, as single nucleotide polymorphisms, which was also reported in other hormone-dependent cancers. We will review here the implication of GPER/GPR30 in TGCCs pathophysiology and the arguments to consider GPER/GPR30 as a potential therapeutic target in humans.

Abstract
INTRODUCTION The objective of this study was to assess recent trends in incidence, mortality and relative survival (RS) in testicular cancer (TC) patients in Belarus and to provide international comparisons of our figures. MATERIAL AND METHODS We surveyed the Belarusian Cancer Registry for all male cases diagnosed with International Classification of Diseases for Oncology, third edition (ICD-O-3) topography code C62 between 1990 and 2015. Trends for incidence and mortality rates per 100,000 of the world standard population and annual percentage changes (APCs) were calculated. We also estimated the 1- and 5-year RS rates for the 1990-1998, 1999-2007 and 2008-2015 periods according to the Ederer II method. The RS estimates for the 2008-2015 period were age-standardized and compared with the published EUROCARE-5 data and SEER-18 database analysis. RESULTS A total of 2,500 and 2,439 cases were included into incidence and survival analyses, respectively. We found a significant increase in the TC age-standardized incidence rate (APC 2.6%) and a decline in the age-standardized mortality (APC -3.0%) over the study period. RS significantly increased in all patients` strata; a relative increase was more pronounced in advanced stages of seminoma and younger age groups. Nevertheless, the most recent figures of age-standardized RS including stage-specific estimates were generally worse than the European and SEER data. CONCLUSIONS We have found a significant increase in TC incidence in Belarus in recent years. Mortality has significantly declined with a corresponding increase in RS which, however, did not reach European or North American figures. Continued effort is required to improve the quality of management of TC patients in our country.

Abstract
The mortality-to-incidence ratio (MIR) is associated with the clinical outcomes of different types of cancer as well as the ranking of health care systems. However, the association between MIRs for testicular cancer and health care disparities, including differences in expenditures and health system rankings, has not yet been reported. We used the Spearman’s rank correlation coefficient (CC) to analyze the correlation between testicular cancer MIRs and both total expenditures on health/gross domestic product (e/GDP) and the World Health Organization’s (WHO) health system rankings. After screening the data for quality and missing information, 57 countries were chosen for analysis. Generally, developed countries and regions had relatively high rates of incidence/mortality, but with a favorable MIR. Among the continents, Europe had the highest incidence rates, whereas the highest MIRs were in Africa. Globally, favorable testicular cancer MIRs were observed in countries with both a high e/GDP and a good WHO ranking (R2 = 0.325, p < 0.001 and CC = −0.568, p < 0.001; R2 = 0.367, p < 0.001 and CC = 0.655, p < 0.001, respectively). In conclusion, the MIR for testicular cancer varies in countries and regions based on both their total health expenditure and their health care system ranking.

Abstract
PURPOSE To synthesise literature in order to elucidate the experiences of men who have survived testicular cancer and determine their quality of life following treatment. METHODS An integrated review sought appropriate literature by utilising a keyword search across seven databases. Retrieved studies were appraised for quality, with 2 qualitative, 12 quantitative and 2 mixed method studies deemed appropriate for this review. The data were extracted and aggregated into categories by way of a thematic analysis. The themes were personal challenges and impact on health, psychological and emotive challenges, perception of reproduction and sexual changes and outlook and support. RESULTS Men experienced physical, emotional and sexual difficulties. Some men believed they were infertile, despite evidence that fertility is not compromised in the long term. Psychological conditions can be exacerbated by cultural pressures to conceive and cultural expressions about male identity. Men who had undergone orchidectomy reported minimal impact on their mental health than the men who had chemotherapy or radiotherapy as part of their treatment modality. Sexual dysfunction caused by chemotherapy-associated side effects was detrimental to men's quality of life. In addition, men who had a partner, who were employed, and who had children were able to adjust better after treatment than those who did not. Provision of clear and honest information post-treatment helped testicular cancer survivors return to their normal lives. CONCLUSIONS The evidence from the review suggests that the burden of disease for testicular cancer survivors is overall low. Men who had surgical intervention and were treated for testicular cancer experienced minimal impact on their mental health status than the men who had chemotherapy or radiotherapy as part of their treatment modality. IMPLICATIONS FOR CANCER SURVIVORS There is a need to provide appropriate referrals to the relevant services, including psychosocial support, and the development of more adequate communication resources for men following treatment for testicular cancer.

Abstract
Testicular germ cell cancer (TGCC) is the most frequent cancer of the young male, with an increasing incidence worldwide. The pathogenesis and reasons for this increase remain unknown. However, epidemiological and experimental data have suggested that, similar to genital malformations and sperm impairment, it could result from the interaction of genetic and environmental factors including fetal exposure to endocrine-disrupting chemicals (EDCs) with estrogenic effects. In this review, we analyze the expression of classic and nonclassic estrogen receptors by TGCC cells, the way they may influence germ cell proliferation induced by EDCs, and discuss how this estrogen dependency supports the developmental and environmental hypothesis.

Abstract
BACKGROUND Incidence rates of testicular cancer (TC) have been increasing in many countries since, at least, the mid-20th century without clear explanation. Examining the varying trends across countries and time provides clues to understanding the causes of TC. OBJECTIVE We have presented incidence data from 41 countries and evaluated incidence trends for the 35-yr period from 1978 to 2012. DESIGN, SETTING, AND PARTICIPANTS Cancer registry data from Cancer Incidence in Five Continents (CI5) volumes V-XI, CI5plus, and the NORDCAN database were analysed. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Age-standardised rates of TC overall and by histological type were calculated. A joinpoint regression model of the natural log-transformed rates was used to calculate the average annual percent change (AAPC) in incidence. Age-period-cohort modelling was used to examine the effect of birth cohort on rates. RESULTS AND LIMITATIONS While the highest incidence of TC remains in Northern Europe, the gap is closing between higher- and lower-incidence regions. Age-period-cohort modelling found flattening of risk among recent cohorts in Denmark and the UK, a steady increase in risk in the USA (particularly for seminomas), and an increase in risk among more recent cohorts in Costa Rica, Croatia, and Slovakia. CONCLUSIONS The gap between low- and high-incidence countries is closing due to increases in the former and stabilisation in the latter. Understanding the causes of these and other differences in incidence rates between, and within, countries may help further our understanding of the aetiology of this cancer. PATIENT SUMMARY We examined the rates of testicular cancer in different countries over time. These rates have been increasing, although the rates in high-incidence countries seem to be slowing down, while rates in low-incidence countries are catching up. These trends might help us understand what is causing testicular cancer in general.

Abstract
OBJECTIVE To investigate the effect of connexin43 (Cx43) protein on autophagy in cisplatin (DDP)-resistant testicular cancer I-10 cells. METHODS The expression of Cx43 proteins in testicular cancer I-10 cells and I-10/DDP cells were detected with Western blotting. I-10/DDP cells were transfected with a full- length mouse Cx43 vector (mCx43) via Lipofectamine2000, the empty vector or Lipofectamine2000 (blank control group), and the changes in the expressions of LC3 and p62 proteins were determined with Western blotting. mCherry-GFP-LC3B transfection and transmission electron microscopy were used to analyze the changes in autophagy of the cells with Cx43 overexpression. RESULTS Cx43 was significantly decreased in I-10/DDP cells compared with I-10 cells (P < 0.01). Transfection of the I-10/DDP cells with mCx43 vector resulted in significantly increased Cx43 expression in the cells (P < 0.01) and caused significantly decreased expression of LC3-Ⅱ (P < 0.01) and increased expression of p62 (P < 0.05) as compared with the negative control cells. Both transmission electron microscopy and mCherry-GFP-LC3B transfection showed that the number of autophagosomes was obviously reduced in mCx43-transfected cells as compared with the negative control cells. CONCLUSIONS Cx43 inhibits autophagy in cisplatin-resistant testicular cancer I-10 /DDP cells.

The effects of perfluorooctanoic acid (PFOA) on fetal and adult rat testis. Reprod Toxicol 2019; 90:68-76. [PMID: 31412280 DOI: 10.1016/j.reprotox.2019.08.005] [Citation(s) in RCA: 48] [Impact Index Per Article: 9.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2019] [Revised: 08/06/2019] [Accepted: 08/09/2019] [Indexed: 11/24/2022]
Abstract
Perfluorooctanoic acid (PFOA) is a widely dispersed synthetic chemical, which accumulates in living organisms and has been connected with male reproductive disorders. To monitor the effects of PFOA, fetal rat testes or seminiferous tubule segments (stage VII-VIII) of adult rats were cultured in 0-100 μg/ml PFOA for 24 h. Afterwards, cAMP, progesterone, testosterone and StAR protein levels were measured from the fetal testes culture. Measurements were combined with immunohistochemistry, immunofluorescence, TUNEL and flow cytometric analysis to monitor cell death in somatic and germ cells. This study shows that the levels of cAMP, progesterone, testosterone and expression of StAR decreased significantly in PFOA 50 and 100 μg/ml. PFOA affected cell populations significantly by decreasing the amount of diploid, proliferating, meiotic I and G2/M-phase cells in adult rat testis. However, PFOA did not affect fetal, proliferating or adult rat Sertoli cells but an increased tendency of apoptosis in fetal Leydig cells was observed.
