[PMID: 38851302 DOI: 10.1016/j.matbio.2024.06.001] [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: 02/14/2024] [Revised: 05/10/2024] [Accepted: 06/03/2024] [Indexed: 06/10/2024]
Abstract
Germ cell tumors (GCT) are the most common solid tumors in young men of age 15 - 40. In previous studies, we profiled the interaction of GCT cells with cells of the tumor microenvironment (TM). Earlier studies showed that especially the 3D interaction of fibroblasts (FB) or macrophages with GCT cells influenced the growth behavior and cisplatin response as well as the transcriptome and secretome of the tumor cells, suggesting that the crosstalk of these cells with GCT cells is crucial for tumor progression and therapy outcome. In this study, we shed light on the mechanisms of activation of cancer-associated fibroblasts (CAF) in the GCT setting and their effects on GCT cells lines and the monocyte cell line THP-1. Ex vivo cultures of GCT-derived CAF were established and characterized molecularly and epigenetically by performing DNA methylation arrays, RNA sequencing, and mass spectrometry-based secretome analysis. We demonstrated that the activation state of CAF is influenced by their former prevailing tumor environment in which they have resided. Hereby, we postulated that seminoma (SE) and embryonal carcinoma (EC) activate CAF, while teratoma (TER) play only a minor role in CAF formation. In turn, CAF influence proliferation and the expression of cisplatin sensitivity-related factors in GCT cells lines as well as polarization of in vitro-induced macrophages by the identified effector molecules IGFBP1, LGALS3BP, LYVE1, and PTX3. Our data suggests that the vital interaction of CAF with GCT cells and with macrophages has a huge influence for shaping the extracellular matrix as well as for recruitment of immune cells to the tumor microenvironment. In conclusion, therapeutically interfering with CAF and / or macrophages in addition to the standard therapy might slow-down progression of GCT and re-shaping of the TM to a tumor-promoting environment. Significance: The interaction of CAF with GCT and macrophages considerably influences the microenvironment. Thus, therapeutically interfering with CAF might slow-down progression of GCT and re-shaping of the microenvironment to a tumor-promoting environment.

Abstract
BACKGROUND Immune cell infiltration is heterogeneous but common in testicular germ cell tumors (TGCT) and pre-invasive germ cell neoplasia in situ (GCNIS). Tumor-infiltrating T cells including regulatory T (Treg) and follicular helper T (Tfh) cells are found in other cancer entities, but their contributions to TGCT are unknown. METHODS Human testis specimens from independent patient cohorts were analyzed using immunohistochemistry, flow cytometry and single-cell RNA sequencing (scRNA-seq) with special emphasis on delineating T cell subtypes. RESULTS Profound changes in immune cell composition within TGCT, shifting from macrophages in normal testes to T cells plus B and dendritic cells in TGCT, were documented. In most samples (96%), the CD4+ T cell frequency exceeded that of CD8+ cells, with decreasing numbers from central to peripheral tumor areas, and to tumor-free, contralateral testes. T cells including Treg and Tfh were most abundant in seminoma compared to mixed tumors and embryonal carcinoma. CONCLUSION Despite considerable heterogeneity between patients, T cell subtypes form a key part of the TGCT microenvironment. The novel finding of rare Treg and Tfh cells in human testis suggests their involvement in TGCT pathobiology, with implications for understanding tumor progression, to assess patients' prognosis, and as putative targets for personalized immunotherapy.

Predictive tissue markers in testicular germ cell tumors: Immunohistochemical expression of MLH1 and REV-7 proteins. Int Urol Nephrol 2024; 56:1887-1898. [PMID: 38285100 PMCID: PMC11090952 DOI: 10.1007/s11255-023-03933-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Accepted: 12/27/2023] [Indexed: 01/30/2024]
Abstract
PURPOSE Testicular Germ Cell Tumors (TGCTs) are the most frequent solid malignancies in young adult men. Regardless of differences in their cell of origin, all TGCTs are considered highly curable malignancies. However, approximately 3-5% of all TGCTs do not respond to platinum-based chemotherapies. The purpose of our paper is to investigate whether immunohistochemical expression of MLH1 and REV-7 can be used as predictive tissue markers for TGCTs. MATERIAL AND METHODS The main demographic and clinicopathological characteristics of 64 male patients with TGCTs who underwent orchiectomy from 2007 to 2022 were retrospectively obtained from two large Oncology Clinics in Greece. Both patients with chemosensitive and chemoresistant disease were included. Immunohistochemical staining for MLH1 and REV-7 proteins was applied in specimens of these patients. RESULTS 31 seminomas and 33 non-seminomas were included. 48 patients had chemosensitive disease, while 16 had chemoresistant disease. 53 specimens showed preserved MLH1 expression, while 11 specimens had lost MLH1 expression. Expression of MLH1 was only significantly associated with patients' age. 16 specimens showed positive REV-7 expression, while 48 specimens were REV-7 negative. Interestingly, 50% of patients with chemoresistant disease and 16,7% of patients with chemosensitive disease were REV-7 positive. This difference was statistically significant. Moreover, REV-7 positivity was significantly associated with chemoresistance, various clinicopathological parameters and patients' prognosis and survival. CONCLUSION Loss of MLH1 expression was only found to be significantly associated with lower patients' age. Positive immunohistochemical REV-7 expression was significantly associated with various clinicopathological parameters, while it was also associated with significantly lower survival and greater hazard. REV-7 positive percentages were significantly higher in patients with chemoresistant disease. Our findings imply that immunohistochemical staining for REV-7 could potentially be used as a predictive tissue marker for TGCT tumors. Moreover, targeting of REV-7 protein, could represent a potential therapeutic strategy for chemoresistant TGCT cases. The implementation of well-designed studies on a larger scale is of utmost importance, in order to draw safer conclusions. Additional studies are needed so as to draw safer conclusions.

Abstract
BACKGROUND Testicular germ cell tumors (TGCTs) exhibit diverse biological and pathological features and are divided in two main types, seminomas and nonseminomatous germ cell tumors (NSGCTs). CD44 is a cell surface receptor, which is highly expressed in malignancies and is implicated in tumorigenesis affecting cell-matrix interactions and cell signaling. METHODS AND RESULTS Here, we examined the expression of CD44 in tumor cell lines and in patients' material. We found that CD44 is over-expressed in TGCTs compared to normal tissues. Immunohistochemical staining in 71 tissue specimens demonstrated increased expression of CD44 in some patients, whereas CD44 was absent in normal tissue. In seminomas, a high percentage of tumor and stromal cells showed cytoplasmic and/or cell surface staining for CD44 as well as increased staining for CD44 in the tumor stroma was found in some cases. The increased expression of CD44 either in tumor cells or in stromal components was associated with tumor size, nodal metastasis, vascular/lymphatic invasion, and disease stage only in seminomas. The increased stromal expression of CD44 in TGCTs was positively associated with angiogenesis. CONCLUSIONS CD44 may exhibit diverse biological functions in seminomas and NSGCTs. The expression of CD44 in tumor cells as well as in tumor stroma fosters an aggressive phenotype in seminomas and should be considered in disease treatment.

Abstract
The current WHO classification of testicular germ cell tumors is based on the pathogenesis of the tumors driven by different genomic events. The germ cell neoplasia in situ is the precursor lesion for all malignant germ cell tumors. The current understanding of pathogenesis is that the developmental and environmental factors with the erasure of parental genomic imprinting lead to the development of abnormal gonocytes that settle in the "spermatogonial Niche" in seminiferous tubules. The abnormal primordial germ cells in the seminiferous tubules give rise to pre-GCNIS cells under the influence of TPSY and OCT4 genes. The whole genome duplication events give rise to germ cell neoplasia in situ, which further acquires alterations in 12p along with NRAS and KRAS mutations to produce seminoma. A subset of seminomas acquires KIT mutation and does not differentiate further. The remaining KIT-stable seminomas differentiate to nonseminomatous GCTs after obtaining recurrent chromosomal losses, epigenetic modification, and posttranscriptional regulation by multiple genes. Nonseminomatous germ cell tumors also develop directly from differentiated germ cell neoplasia in situ. TP53 pathway with downstream drivers may give rise to somatic-type malignancies of GCT. The GCTs are remarkably sensitive to cisplatin-based combination chemotherapy; however, resistance to cisplatin develops in up to 8% of tumors and appears to be driven by TP53/MDM2 gene mutations. Serum and Plasma miRNAs show promise in diagnosing, managing, and following up on these tumors. The mechanisms underlying the development of most tumors have been elucidated; however, additional studies are required to pinpoint the events directing specific characteristics. Advances in identifying specific molecular markers have been seen recently and may be adopted as gold standards in the future.

Abstract
Polyorchidism, a congenital malformation characterized by supernumerary testes (SNTs), is usually revealed incidentally during ultrasound or open scrotal surgery. In the approximately 200 cases so far published in the literature, the left side is affected more often than the right. Despite the rarity of this anomaly, a surgeon must have basic knowledge of its embryological basis and classifications to implement proper treatment and avoid overlooking it, since the consequences could harm the patient. This review summarizes previous classifications. It can be assumed that determining the risk of malignancy, and the level of reproductive potential based on location, vascularization, ductus deferens drainage, and environmental factors (e.g., temperature) affecting the SNTs, indicates the best approach to management. Therefore, we have created a new classification based on previous ones, addressing the aforementioned issues, which will guide the clinician to select the most appropriate treatment.

Abstract
Background Testicular germ cell tumor (TGCT) is the most common type of malignancy in young men, but rarely in older adults. We aimed to construct a competing risk model to predict the prognosis for older patients with TGCT. Methods We collected TGCT patients aged 50 years or older diagnosed between 2004 and 2015 from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database. We estimated the cumulative incidences of cause-specific death (CSD) and other causes of death and established a nomogram predicting cause-specific mortality in older patients with TGCT by Fine-Gray competing risk regression. The concordance index (C-index), calibration curves, area under the receiver operating characteristic curve (AUC), and decision analysis curves (DCA) were used to evaluate the differentiation, accuracy, and clinical significance of the nomogram. Results A total of 2,751 older TGCT patients were included in the study. The 3-, 5-, and 10-year cumulative incidences were 4.4, 5.0 and 6.1%, respectively, for cause-specific death, and 3.8, 6.2, 13.1%, respectively, for other causes of death. Predictors of cause-specific mortality in older TGCT included age, marital status, annual household income, histology, tumor size, stage and surgery. In the training and validation sets, the C-indexes were greater than 0.8, indicating that the nomogram had good discrimination. The AUC revealed the same result. The calibration curves showed good agreement between the predicted and observed results of the nomogram. DCA curves indicated that the nomogram had more clinical significance than the conventional American Joint Committee on Cancer (AJCC) staging. Based on the total nomogram score of each case, all patients were categorized into low-risk and high-risk groups, and risk categorization allowed the identification of cases with a high risk of death. Conclusion We established a competing risk nomogram with good performance that may help clinicians accurately predict the prognosis of older TGCT patients.

Abstract
Testicular cancer survivors (TCS) treated with platinum-based chemotherapy have an increased risk of colorectal cancer (CRC). We determined the yield of colonoscopy in TCS to assess its potential in reducing CRC incidence and mortality. We conducted a colonoscopy screening study among TCS in four Dutch hospitals to assess the yield of colorectal neoplasia. Neoplasia was defined as adenomas, serrated polyps (SPs), advanced adenomas (AAs: ≥10 mm diameter, high-grade dysplasia or ≥25% villous component), advanced serrated polyps (ASPs: ≥10 mm diameter or dysplasia) or CRC. Advanced neoplasia (AN) was defined as AA, ASP or CRC. Colonoscopy yield was compared to average-risk American males who underwent screening colonoscopy (n = 24,193) using a propensity score matched analysis, adjusted for age, smoking status, alcohol consumption and body mass index. A total of 137 TCS underwent colonoscopy. Median age was 50 years among TCS (IQR 43-57) vs 55 years (IQR 51-62) among American controls. A total of 126 TCS were matched to 602 controls. The prevalence of AN was higher in TCS than in controls (8.7% vs 1.7%; P = .0002). Nonadvanced adenomas and SPs were detected in 45.2% of TCS vs 5.5% of controls (P < .0001). No lesions were detected in 46.0% of TCS vs 92.9% of controls (P < .0001). TCS treated with platinum-based chemotherapy have a higher prevalence of neoplasia and AN than matched controls. These results support our hypothesis that platinum-based chemotherapy increases the risk of colorectal neoplasia in TCS. Cost-effectiveness studies are warranted to ascertain the threshold of AN prevalence that justifies the recommendation of colonoscopy for TCS.

Abstract
BACKGROUND Numerous observational epidemiological studies have reported a bidirectional relationship between periodontitis and urological cancers. However, the causal link between these two phenotypes remains uncertain. This study aimed to examine the bidirectional causal association between periodontitis and four types of urological tumors, specifically kidney cancer (KC), prostate cancer (PC), bladder cancer (BC), and testis cancer (TC). METHODS Based on large-scale genome-wide association study (GWAS) data, we utilized the two-sample Mendelian randomization (MR) approach to evaluate causal relationships between periodontitis and urological cancers. Several MR methods covering various consistency assumptions were applied in this study, including contamination mixture and Robust Adjusted Profile Score to obtain robust results. Summary-level data of individuals with European ancestry were extracted from the UK Biobank, the Kaiser GERA cohorts, and the FinnGen consortium. RESULTS Our findings revealed significant positive genetic correlations between periodontitis and kidney cancer (OR 1.287; 95% CI 1.04, 1.594; P = 0.020). We did not find a significant association of periodontitis on prostate cancer, bladder cancer, and testis cancer. In reverse MR, no significant results were observed supporting the effect of urologic cancers on periodontitis (all P > 0.05). CONCLUSION Our study provides the evidence of a potential causal relationship between periodontitis and kidney cancer. However, large-scale studies are warranted to confirm and elucidate the underlying mechanisms of this association.

Advancing GCT Management: A Review of miR-371a-3p and Other miRNAs in Comparison to Traditional Serum Tumor Markers. Cancers (Basel) 2024; 16:1379. [PMID: 38611057 PMCID: PMC11010994 DOI: 10.3390/cancers16071379] [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: 03/08/2024] [Revised: 03/29/2024] [Accepted: 03/29/2024] [Indexed: 04/14/2024] Open
Abstract
MicroRNAs, short non-protein coding RNAs, are overexpressed in GCTs. Circulating levels of germ cell tumor (GCT)-associated miRNAs, such as miR-371a-3p, can be utilized as efficient and cost-effective alternatives in diagnosing and managing patients presenting with GCTs. This quality of miRNAs has demonstrated favorable performance characteristics as a reliable blood-based biomarker with high diagnostic accuracy compared to current serum tumor markers (STMs), including α-fetoprotein (AFP), beta human chorionic gonadotropin (β-hCG), and lactate dehydrogenase (LDH). The conventional STMs exhibit limited specificity and sensitivity. Potential clinical implications of miRNAs include impact on de-escalating or intensifying treatment, detecting recurrence at earlier stages, and lessening the necessity of cross-sectional imaging or invasive tissue biopsy for non-teratomatous GCTs. Here, we also highlight the outstanding issues that must be addressed prior to clinical implementation. Standards for measuring circulating miRNAs and determining ideal cutoff values are essential for integration into current clinical guidelines.

Abstract
In germ cell tumors (GCT), a growing teratoma during chemotherapy with decreasing tumor markers was defined as 'growing teratoma syndrome' (GTS) by Logothetis et al. in 1982. So far, its pathogenesis and specific treatment options remain elusive. We aimed at updating the GTS definition based on molecular and epigenetic features as well as identifying circulating biomarkers. We selected 50 GTS patients for clinical characterization and subsequently 12 samples were molecularly analyzed. We further included 7 longitudinal samples of 2 GTS patients. Teratomas (TER) showing no features of GTS served as controls. GTS were stratified based on growth rates into a slow (<0.5 cm/month), medium (0.5-1.5) and rapid (>1.5) group. By analyzing DNA methylation, microRNA expression and the secretome, we identified putative epigenetic and secreted biomarkers for the GTS subgroups. We found that proteins enriched in the GTS groups compared to TER were involved in proliferation, DNA replication and the cell cycle, while proteins interacting with the immune system were depleted. Additionally, GTSrapid seem to interact more strongly with the surrounding microenvironment than GTSslow. Expression of pluripotency- and yolk-sac tumor-associated genes in GTS and formation of a yolk-sac tumor or somatic-type malignancy in the longitudinal GTS samples, pointed at an additional occult non-seminomatous component after chemotherapy. Thus, updating the Logothetis GTS definition is necessary, which we propose as follows: The GTS describes a continuously growing teratoma that might harbor occult non-seminomatous components considerably reduced during therapy but outgrowing over time again.

Abstract
Background Germ cell tumors (GCTs) represent the most frequent solid malignancy in young men. This malignancy is highly curable by cisplatin (CDDP)-based chemotherapy. However, there is a proportion of patients having a poor prognosis due to refractory disease or its relapse. No reliable biomarkers being able to timely and accurately stratify poor prognosis GCT patients are currently available. Previously, we have shown that chemotherapy-naïve GCT patients with higher DNA damage levels in peripheral blood mononuclear cells (PBMCs) have significantly worse prognosis compared to patients with lower DNA damage levels. Methods DNA damage levels in PBMCs of both chemotherapy-naïve and first cycle chemotherapy-treated GCT patients have been assessed by standard alkaline comet assay and its styrene oxide (SO)-modified version. These levels were correlated with clinico-pathological characteristics. Results We re-confirm prognostic value of DNA damage level in chemotherapy-naïve GCT patients and reveal that this prognosticator is equally effective in GCT patients after first cycle of CDDP-based chemotherapy. Furthermore, we demonstrate that SO-modified comet assay is comparably sensitive as standard alkaline comet assay in case of patients who underwent first cycle of CDDP-based chemotherapy, although it appears more suitable to detect DNA cross-links. Conclusion We propose that DNA damage levels in PBMCs before and after first cycle of CCDP-based chemotherapy are comparable independent prognosticators for progression-free and overall survivals in GCT patients. Therefore, their clinical use is highly advised to stratify GCT patients to identify those who are most at risk of developing disease recurrence or relapse, allowing tailoring therapeutic interventions to poor prognosis individuals, and optimizing their care management and treatment regimen.

Abstract
Testicular cancer, the most common cancer among young male adults, is associated with infertility. A 38-year-old male patient was admitted to Dokkyo Medical University Saitama Medical Center, Japan, with infertility associated with severe oligozoospermia. Scrotal ultrasonography revealed two distinct tumors in the left testis: A mass with abundant blood flow on the cranial side and a mass with poor blood flow on the caudal side. Additional analysis revealed mild elevation of intact human chorionic gonadotropin (hCG) levels (tumor marker level assessment), high testosterone and low luteinizing hormone and follicle-stimulating hormone levels (hormonal level assessment) and severe oligoasthenozoospermia (semen assessment). The preoperative diagnosis was left-sided testicular cancer and severe oligoasthenozoospermia and the patient underwent left high orchiectomy and oncological testicular sperm extraction. Based on the pathological assessment, the cranial tumor was diagnosed as a seminoma with syncytiotrophoblastic cells, whereas the caudal tumor had only scar tissue with germ cell neoplasia in situ in the adjacent parenchyma. Following surgery, intact hCG and hormone levels of the patient were normalized, and the semen parameters (semen volume, sperm density, and motility) improved dramatically. To the best of our knowledge, the present case is the first report of two types of testicular tumor in a unilateral testis in a patient with a history of cryptorchidism surgery. The present case demonstrated that scrotal ultrasonography should be performed in patients with abnormal semen results to rule out testicular tumors.

Abstract
Advancements in cutting-edge molecular profiling techniques, such as next-generation sequencing and bioinformatic analytic tools, have allowed researchers to examine tumour biology in detail and stratify patients based on factors linked with clinical outcome and response to therapy. This manuscript highlights the most relevant prognostic and predictive biomarkers in kidney, bladder, prostate and testicular cancers with recognised impact in clinical practice. In bladder and prostate cancer, new genetic acquisitions concerning the biology of tumours have modified the therapeutic scenario and led to the approval of target directed therapies, increasing the quality of patient care. Thus, it has become of paramount importance to choose adequate molecular tests, i.e., FGFR screening for urothelial cancer and BRCA1-2 alterations for prostate cancer, to guide the treatment plan for patients. While no tissue or blood-based biomarkers are currently used in routine clinical practice for renal cell carcinoma and testicular cancers, the field is quickly expanding. In kidney tumours, gene expression signatures might be the key to identify patients who will respond better to immunotherapy or anti-angiogenic drugs. In testicular germ cell tumours, the use of microRNA has outperformed conventional serum biomarkers in the diagnosis of primary tumours, prediction of chemoresistance, follow-up monitoring, and relapse prediction.

Abstract
BACKGROUND Testicular cancer (TC), comprising merely 1% of male neoplasms, holds the distinction of being the most commonly encountered neoplasm among young males. RECENT FINDINGS Most cases of testicular neoplasms can be classified into two main groups, namely germ cell tumors representing approximately 95% of the cases, and sex cord-stromal tumors accounting for about 5% of the cases. Moreover, its prevalence is on the rise across the globe. TC is a neoplastic condition characterized by a favorable prognosis. The advent of cisplatin-based chemotherapeutic agents in the latter part of the 1970s has led to a significant enhancement in the 5-year survival rate, which presently surpasses 95%. Given that TC is commonly detected before reaching the age of 40, it can be anticipated that these individuals will enjoy an additional 40-50 years of life following successful treatment. The potential causes of TC are multifactorial and related to different pathologies. Accurate identification is imperative to guarantee the utmost efficacious and suitable therapy. To a certain degree, this can be accomplished through the utilization of blood examinations for neoplastic indicators; nonetheless, an unequivocal diagnosis necessitates an evaluation of the histological composition of a specimen via a pathologist. CONCLUSION TC is multifactorial and has various pathologies, therefore this review aimed to revise the prenatal and postnatal causes as well as novel diagnostic biomarkers and the therapeutic strategies of TC.

Abstract
BACKGROUND Testicular cancer (TC) mostly occurs in men aged 14 to 44. Studies have shown that TC seriously damages male fertility, and 6% to 24% of patients with TC were even found to suffer from azoospermia when they are diagnosed. At present, some studies have pointed out that onco-microdissection testicular sperm extraction (mTESE) can extract sperm from tumor testicles. However, there are almost no reports on remedial measures after onco-mTESE failure. Given the valuable opportunity for fertility preservation in patients with TC and azoospermia, it is necessary to provide effective remedial methods for patients with failed onco-mTESE. METHODS Two young men, who were diagnosed with TC and also found to have azoospermia, tried onco-mTESE while undergoing radical orchiectomy for fertility preservation. However, sperm extraction failed in both patients. Subsequently, the isolated testicular tissue of the patient in case 1 suffered from TC again, and the patient in case 2 was scheduled to receive multiple cycles of gonadotoxic chemotherapy. Because both had a plan to have a birth in the future, we performed remedial mTESE. RESULTS Sperm was successfully extracted from both patients. The patient recovered well, without complications. The patient couple in case 1 underwent 1 intracytoplasmic sperm injection (ICSI) cycle but did not achieve clinical pregnancy. CONCLUSIONS There is still an opportunity to extract sperm successfully using onco-mTESE, despite the difficulty of fertility preservation in TC patients with azoospermia. If sperm extraction from the tumor testis fails, implementing remedial mTESE as early as possible would likely preserve the last chance of fertility for these patients.

Abstract
Sarcomatoid yolk sac tumor is a very rare histologic type of testicular germ cell tumor and is mainly reported in testicular germ cell tumor patients who receive chemotherapy. Herein, we report an extremely rare concurrent retroperitoneal sarcomatoid yolk sac tumor in a man with a testicular postpuberal teratoma before he received chemotherapy. A 37-year-old man initially presented with a persistent abdominal pain. Subsequent imaging studies revealed a 9.6-cm retroperitoneal mass, and 2 testicular masses (3.1 cm and 0.9 cm in greatest dimension, respectively). His serum tumor markers were within normal ranges. His radical orchiectomy demonstrated a postpubertal type teratoma with an adjacent scarring nodule. Later, his retroperitoneal tumor showed spindle tumor cells embedded in predominantly myxoid and focally fibrous stroma with diffuse and strong immunoreactivity for keratin AE1/AE3, SALL4 and glypican 3. No tumor necrosis or brisk mitotic figures were observed. A diagnosis of sarcomatoid yolk sac tumor was rendered. Fluorescence in situ hybridization analysis of his retroperitoneal sarcomatoid yolk sac tumor revealed polysomy 12 and MYC amplification, whereas no evidence of isochromosome 12p [i(12p)], and DNA sequencing showed 6 mutations per megabase (muts/Mb), and the somatic alterations included ARAF amplification and ATR I774Yfs*5. Considering its rarity, sarcomatoid yolk sac tumor may pose diagnostic challenges. Therefore, relevant clinicoradiologic information and ancillary work up, including immunohistochemistry and molecular studies, may be helpful for the accurate classification. Our tumor further raises awareness of this rare event, expands the spectrum of its clinical presentation, and explores the molecular features.

Abstract
Objective The purpose of this study was to compare the clinical characteristics and outcomes of children with cryptorchidism testicular torsion between the younger age group and the older age group. Methods We collected the clinical data of children with cryptorchidism complicated with testicular torsion in our hospital from January 1, 2013 to January 1, 2023. The patients were divided into two groups: the younger age group (1month∼4 years old, n = 7) and the older age group (4∼18 years old, n = 7). The differences of clinical manifestations and surgical results between the two groups were compared. Results A total of 14 patients with unilateral cryptorchidism testicular torsion were included in this study, including 9 on the left side and 5 on the right side. The main clinical manifestations were pain /swelling of groin. The rate of crying in the younger age group was significantly higher than those in the older age group [(5,71.4%) vs. (0,0.0%), P < 0.05]. The median duration of symptoms of the younger group was less than the older group [42(7,96) h vs. 70(24, 96) h, P > 0.05]. The ipsilateral testicular salvage rate in the younger age group was 14.3% (1/7), which was lower than the older age group 57.1% [(4/7), P > 0.05]. The degree of testicular torsion in younger age group was more severe than the older age group [720(360, 1,080)° vs. 360(270, 360)°, P > 0.05]. Conclusions The overall salvage rate of cryptorchidism testicular torsion is low. Although the duration of symptoms in the older age group was longer, the salvage rate of the older age group seemed to be higher than that in the younger age group. In addition, physical and imaging examination of the reproductive system should be carried out in time to identify the children with cryptorchidism testicular torsion in the early stage.

Abstract
Cryptorchidism is the most common form of disorder of sex development in male dogs, but its hereditary predisposition is poorly elucidated. The gonadal transcriptome of nine unilaterally cryptorchid dogs and seven control dogs was analyzed using RNA-seq. Comparison between the scrotal and inguinal gonads of unilateral cryptorchid dogs revealed 8,028 differentially expressed genes (DEGs) (3,377 up-regulated and 4,651 down-regulated). A similar number of DEGs (7,619) was found by comparing the undescended testicles with the descended testicles of the control dogs. The methylation status of the selected DEGs was also analyzed, with three out of nine studied DEGs showing altered patterns. Bioinformatic analysis of the cDNA sequences revealed 20,366 SNP variants, six of which showed significant differences in allelic counts between cryptorchid and control dogs. Validation studies in larger cohorts of cryptorchid (n = 122) and control (n = 173) dogs showed that the TT genotype (rs850666472, p.Ala1230Val) and the AA genotype in 3'UTR (16:23716202G>A) in KATA6, responsible for acetylation of lysine 9 in histone H3, are associated with cryptorchidism (P = 0.0383). Both the transcript level of KAT6A and H3K9 acetylation were lower in undescended testes, and additionally, the acetylation depended on the genotypes in exon 17 and the 3'UTR. Our study showed that the massive alteration of the transcriptome in undescended testicles is not caused by germinal DNA variants in DEG regulatory sequences but is partly associated with an aberrant DNA methylation and H3K9 acetylation patterns. Moreover, variants of KAT6A can be considered markers associated with the risk of this disorder.

Perspectives and Concerns on Late Effects Regarding Sexuality among Adolescents and Young Adults Treated for Testicular Germ Cell Tumor: The PRICELESS-Study-A Qualitative Study. Cancers (Basel) 2024; 16:715.

Abstract
This study aimed to explore perspectives and concerns regarding sexuality among adolescents and young adults (AYAs) possibly experiencing late effects after testicular germ cell tumor (TGCT) treatment. A qualitative study was performed in which semi-structured interviews were held with thirteen AYAs from a center of expertise for TGCT in the Netherlands. Data were analyzed using Braun and Clark's thematic analysis method. Seven interacting and interconnected themes were found: desire to have children, rediscovering sexuality, insecurity about sexual performance, acceptance of physical change, loss of masculinity, burden on relationship, and openness in discussing sexuality. Concerns about the desire to have children seem to play a significant role. In conclusion, TGCT patients face multiple changes (physical, emotional, relational, and sexual), followed by a difficult period of acceptance, after which a new phase of rediscovering sexuality appeared. These findings can help to make healthcare professionals aware of the underlying mechanisms and concerns about sexuality. Furthermore, insights can help to develop sexuality-themed items for a broader monitoring tool to structurally assess the late effects to support discussing sexuality.

Androgen Insensitivity Syndrome with Bilateral Gonadal Sertoli Cell Lesions, Sertoli-Leydig Cell Tumor, and Paratesticular Leiomyoma: A Case Report and First Systematic Literature Review. J Clin Med 2024; 13:929. [PMID: 38398243 PMCID: PMC10889606 DOI: 10.3390/jcm13040929] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2023] [Revised: 01/28/2024] [Accepted: 02/01/2024] [Indexed: 02/25/2024] Open
Abstract
Androgen insensitivity syndrome (AIS) is a rare Mendelian disorder caused by mutations of the androgen receptor (AR) gene on the long arm of the X chromosome. As a result of the mutation, the receptor becomes resistant to androgens, and hence, karyotypically male patients (46,XY) carry a female phenotype. Their cryptorchid gonads are prone to the development of several types of tumors (germ cell, sex cord stromal, and others). Here, we report a 15-year-old female-looking patient with primary amenorrhea who underwent laparoscopic gonadectomy. Histologically, the patient's gonads showed Sertoli cell hamartomas (SCHs) and adenomas (SCAs) with areas of Sertoli-Leydig cell tumors (SLCTs) and a left-sided paratesticular leiomyoma. Rudimentary Fallopian tubes were also present. The patient's karyotype was 46,XY without any evidence of aberrations. Molecular genetic analysis of the left gonad revealed two likely germline mutations-a pathogenic frameshift deletion in the AR gene (c.77delT) and a likely pathogenic missense variant in the RAC1 gene (p.A94V). Strikingly, no somatic mutations, fusions, or copy number variations were found. We also performed the first systematic literature review (PRISMA guidelines; screened databases: PubMed, Scopus, Web of Science; ended on 7 December 2023) of the reported cases of patients with AIS showing benign or malignant Sertoli cell lesions/tumors in their gonads (n = 225; age: 4-84, mean 32 years), including Sertoli cell hyperplasia (1%), Sertoli cell nodules (6%), SCHs (31%), SCAs (36%), Sertoli cell tumors (SCTs) (16%), and SLCTs (4%). The few cases (n = 14, 6%; six SCAs, four SCTs, two SLCTs, and two SCHs) with available follow-up (2-49, mean 17 months) showed no evidence of disease (13/14, 93%) or died of other causes (1/14, 7%) despite the histological diagnosis. Smooth muscle lesions/proliferations were identified in 19 (8%) cases (including clearly reported rudimentary uterine remnants, 3 cases; leiomyomas, 4 cases). Rudimentary Fallopian tube(s) were described in nine (4%) cases. Conclusion: AIS may be associated with sex cord/stromal tumors and, rarely, mesenchymal tumors such as leiomyomas. True malignant sex cord tumors can arise in these patients. Larger series with longer follow-ups are needed to estimate the exact prognostic relevance of tumor histology in AIS.

Abstract
Sex hormones play a pivotal role in modulating various physiological processes, with emerging evidence underscoring their influence on cancer progression and treatment outcomes. This review delves into the intricate relationship between sex hormones and cancer, elucidating the underlying biological mechanisms and their clinical implications. We explore the multifaceted roles of estrogen, androgens, and progesterone, highlighting their respective influence on specific cancers such as breast, ovarian, endometrial, and prostate. Special attention is given to estrogen receptor-positive (ER+) and estrogen receptor-negative (ER-) tumors, androgen receptor signaling, and the dual role of progesterone in both promoting and inhibiting cancer progression. Clinical observations reveal varied treatment responses contingent upon hormonal levels, with certain therapies like tamoxifen, aromatase inhibitors, and anti-androgens demonstrating notable success. However, disparities in treatment outcomes between males and females in hormone-sensitive cancers necessitate further exploration. Therapeutically, the utilization of hormone replacement therapy (HRT) during cancer treatments presents both potential risks and benefits. The promise of personalized therapies, tailored to an individual's hormonal profile, offers a novel approach to optimizing therapeutic outcomes. Concurrently, the burgeoning exploration of new drugs and interventions targeting hormonal pathways heralds a future of more effective and precise treatments for hormone-sensitive cancers. This review underscores the pressing need for a deeper understanding of sex hormones in cancer therapy and the ensuing implications for future therapeutic innovations.

Abstract
INTRODUCTION As members of the military, all active duty service members (ADS) must meet physical fitness requirements and are provided with equal-access healthcare through the DoD. In addition, 92% of ADS are ≤40 years of age. Together, these characteristics suggest that ADS represent a healthy population that may have a low risk of cancer. Each year, however, >800 ADS are diagnosed with cancer and the resulting in time off for treatment, reassignment, or medical retirement may significantly impact force readiness. MATERIAL AND METHODS Relevant literature was identified by searching the PubMed database using search terms ACTIVE DUTY and CANCER. Only articles written in English were included. RESULTS Melanoma is the most common cancer in ADS, while testicular cancer is the most common cancer in males and breast cancer is the most common in females. Cancer incidence patterns in ADS differ from those in the general U.S. population and from military veterans. Tumor etiology in ADS may be influenced by military-enriched exposures such as prolonged use of oral contraceptives, suboptimal use of sunscreen, exposure to volatile organic compounds, or germline predisposition/family history. CONCLUSIONS The etiology of cancer within ADS remains largely unknown. A number of new research programs may provide the means to improve understanding of the etiology of cancer in ADS. Together, these efforts will improve prevention, early detection, and clinical management, thus improving the outcomes of ADS and preserving force readiness.

Abstract
Purpose To evaluate the ability of texture features for distinguishing between benign and malignant testicular masses, and furthermore, for identifying primary testicular lymphoma in malignant tumors and identifying seminoma in testicular germ cell tumors, respectively. Methods We retrospectively collected 77 patients with an abdominal and pelvic enhanced computed tomography (CT) examination and a histopathologically confirmed testicular mass from a single center. The ROI of each mass was split into two parts by the largest cross-sectional slice and deemed to be two samples. After all processing steps, three-dimensional texture features were extracted from unenhanced and contrast-enhanced CT images. Excellent reproducibility of texture features was defined as intra-class correlation coefficient ≥0.8 (ICC ≥0.8). All the groups were balanced via the synthetic minority over-sampling technique (SMOTE) method. Dimension reduction was based on pearson correlation coefficient (PCC). Before model building, minimum-redundancy maximum-relevance (mRMR) selection and recursive feature elimination (RFE) were used for further feature selection. At last, three ML classifiers with the highest cross validation with 5-fold were selected: autoencoder (AE), support vector machine(SVM), linear discriminant analysis (LAD). Logistics regression (LR) and LR-LASSO were also constructed to compare with the ML classifiers. Results 985 texture features with ICC ≥0.8 were extracted for further feature selection process. With the highest AUC of 0.946 (P <0.01), logistics regression was proved to be the best model for the identification of benign or malignant testicular masses. Besides, LR also had the best performance in identifying primary testicular lymphoma in malignant testicular tumors and in identifying seminoma in testicular germ cell tumors, with the AUC of 0.982 (P <0.01) and 0.928 (P <0.01), respectively. Conclusion Until now, this is the first study that applied CT texture analysis (CTTA) to assess the heterogeneity of testicular tumors. LR model based on CTTA might be a promising non-invasive tool for the diagnosis and differentiation of testicular masses. The accurate diagnosis of testicular masses would assist urologists in correct preoperative and perioperative decision making.

Abstract
Background Bilateral undescended testes (BUDT) may be a marker of an underlying condition that affects sex development or maturation. Aims To describe the extent of gonadal dysfunction in cases of BUDT who had systematic endocrine and genetic evaluation at a single tertiary pediatric center. Methods A retrospective review was conducted of all boys with BUDT who had endocrine evaluation between 2008 and 2021 at the Royal Hospital for Children, Glasgow (RHCG). Continuous variables were analyzed using Mann-Whitney U and non-continuous variables using Fisher's exact, via Graphpad Prism v 8.0. Multivariable logistic regression was used to identify any associations between groups. A P < .05 was considered statistically significant. Results A total of 243 bilateral orchidopexies were performed at RHCG between 2008 and 2021. Of these 130 (53%) boys were seen by the endocrine team. The median (range) age at first orchidopexy was 1 year (0.2, 18.0) with 16 (12%) requiring re-do orchidopexy. The median External Masculinization Score of the group was 10 (2, 11) with 33 (25%) having additional genital features. Of the 130 boys, 71 (55%) had extragenital anomalies. Of the 70 who were tested, a genetic abnormality was detected in 38 (54%), most commonly a chromosomal variant in 16 (40%). Of the 100 who were tested, endocrine dysfunction was identified in 38 (38%). Conclusion Genetic findings and evidence of gonadal dysfunction are common in boys who are investigated secondary to presentation with BUDT. Endocrine and genetic evaluation should be part of routine clinical management of all cases of BUDT.

Abstract
PURPOSE Testicular cancer is the most frequent malignant tumour among young adults. Therefore, regular self-examination for early detection is recommended by all guidelines. The fact that the knowledge of young adults living in Austria on this important topic is unknown, prompted the current investigation. MATERIALS AND METHODS To evaluate the knowledge on anatomy and function of the male reproductive tract and of testicular cancer in particular a German questionnaire recently developed by Anheuser et al. (Urologe 2019;58:1331-1337) was applied. This 4-page questionnaire contains mainly multiple-choice questions. This questionnaire was distributed in three different schools to male and female students in the 11th and 12th school level. RESULTS A total of 337 students (mean age: 17.3 years; male: n = 183; female: n = 154) completed the questionnaire. In a simple pictogramm, 63% were able to correctly identify the prostate, 87% the testis and 64% the epididymis. Half of the students (49.3%) could describe the function of the testis. The question regarding the age peak of testicular cancer was correctly answered by 81%, yet 18% believed that testicular cancer is caused by the sexual contact. The purpose of the testicular self-examination was correctly answered by only 54.9% with a higher rate for women (67.5% vs. 44.3%, p = 0.001). With a theoretical maximal score of 15, the students reached a mean overall of 10.4 with no sex difference (p > 0.05). Differences were noted for the school type: the highest score was present in the Gymnasium (11.2), followed by the Realgymnasium (10.8) and the HTL (9.8; p = 0.001). CONCLUSIONS This survey demonstrates relevant knowledge deficits of young adults regarding the male reproductive tract, testicular cancer and self-examination.

Abstract
Seminoma is the most common malignant solid tumor in 14 to 44 year-old men. However, its molecular features and tumor microenvironment (TME) is largely unexplored. Here, we perform a series of studies via genomics profiling (single cell multi-omics and spatial transcriptomics) and functional examination using seminoma samples and a seminoma cell line. We identify key gene expression programs share between seminoma and primordial germ cells, and further characterize the functions of TFAP2C in promoting tumor invasion and migration. We also identify 15 immune cell subtypes in TME, and find that subtypes with exhaustion features were located closer to the tumor region through combined spatial transcriptome analysis. Furthermore, we identify key pathways and genes that may facilitate seminoma disseminating beyond the seminiferous tubules. These findings advance our knowledge of seminoma tumorigenesis and produce a multi-omics atlas of in situ human seminoma microenvironment, which could help discover potential therapy targets for seminoma.

Impact of testicular cancer on sperm small non-coding RNA signature: a pilot study. Epigenetics 2023; 18:2241009. [PMID: 37515809 PMCID: PMC10388827 DOI: 10.1080/15592294.2023.2241009] [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: 01/17/2023] [Revised: 07/09/2023] [Accepted: 07/11/2023] [Indexed: 07/31/2023] Open
Abstract
Testicular germ cell tumours (TGCTs) are the most common tumours in young adults of European ancestry. The high heritability and the constantly increased incidence, which has doubled over the last 20 years, strongly suggest that both genetic and environmental factors are likely to shape the TGCT susceptibility. While genome-wide association studies have identified loci associated with TGCT susceptibility, the role played by environmental molecular vectors in TGCT susceptibility remains unclear. Evidence shows that sperm non-coding RNAs provide a good vision of the environmental stresses experienced by men. Here, to determine whether TGCT impacts the abundance of specific non-coding RNAs in sperm, small RNA deep sequencing analysis of sperm of 25 men aged between 19 and 42 years, diagnosed with (n = 16) or without (n = 9) TGCT was performed. The primary analysis showed no statistical significance in the sncRNA population between the TGCT and non-TGCT groups. However, when sperm physiological parameters were considered to look for differentially expressed sncRNA, we evidenced 11 differentially expressed sncRNA between patients and control which allow a clear discrimination between control and TGCT samples after Hierarchical Clustering analysis. Together, these findings indicate that sperm small non-coding RNAs abundance may have the potential for diagnosing men with TGCT. However, specific care should be taken regarding sperm physiological parameters of the TGCT patients. Hence, larger studies are needed to confirm our findings and to determine whether such a signature associates with the risks to develop TGCT.

Abstract
BACKGROUND It is unknown whether five-year overall survival (OS) differs and to what extent between testicular germ-cell tumor (TGCT) patients and age-matched male population-based controls. MATERIALS We identified newly diagnosed (2004-2014) TGCT patients within Surveillance Epidemiology and End Results database 2004-2019. We compared OS between non-seminoma (NS-TGCT) and seminoma (S-TGCT) patients relative to age-matched male population-based controls based on Social Security Administration Life-Tables. Smoothed cumulative incidence plots displayed cancer-specific mortality (CSM) vs. other-cause mortality (OCM). RESULTS Of all 20,935 TGCT patients, 43% had NS-TGCT and 57% had S-TGCT. Of NS-TGCT patients, 63% were stage I vs. 16% stage II vs. 21% stage III. Of S-TGCT patients, 86% were stage I vs. 8% were stage II vs. 6% stage III. Five-year OS differences between NS-TGCT patients vs age-matched male population-based controls were 97 vs. 99% (Δ = 2%) for stage I, 96 vs. 99% (Δ = 3%) for stage II, 76 vs 98% (Δ = 22%) for stage III. Five-year OS differences between S-TGCT patients vs age-matched male population-based controls were 97 vs. 98% (Δ = 1%) for stage I, 95 vs. 97% (Δ = 2%) for stage II, 87 vs. 98% (Δ = 11%) for stage III. OCM rates ranged from 1 to 3% in NS-TGCT patients and from 2 to 4% in S-TGCT patients. CONCLUSION The OS difference between NS-TGCT patients vs. age-matched male population-based controls was invariably higher across all stages (2-22%) than for S-TGCT patients (1-11%). Reassuringly, OCM rates were marginal in stage I and stage II patients. Conversely, higher OCM rates were recorded in stage III patients.

Abstract
Translation initiation in eukaryotes is regulated at several steps, one of which involves the availability of the cap binding protein to participate in cap-dependent protein synthesis. Binding of eIF4E to translational repressors (eIF4E-binding proteins [4E-BPs]) suppresses translation and is used by cells to link extra- and intracellular cues to protein synthetic rates. The best studied of these interactions involves repression of translation by 4E-BP1 upon inhibition of the PI3K/mTOR signaling pathway. Herein, we characterize a novel 4E-BP, C8ORF88, whose expression is predominantly restricted to early spermatids. C8ORF88:eIF4E interaction is dependent on the canonical eIF4E binding motif (4E-BM) present in other 4E-BPs. Whereas 4E-BP1:eIF4E interaction is dependent on the phosphorylation of 4E-BP1, these sites are not conserved in C8ORF88 indicating a different mode of regulation.

Incidence and Survival of Testicular Cancers in a Province in Northern Italy and Their Association with Second Tumors. BIOLOGY 2023; 12:1409.

Abstract
This study investigated the incidence, mortality, and 5-year survival rates of testicular cancers diagnosed in a northern Italian province, which were eventually associated with previous or subsequent extratesticular neoplasms. Cases from 1996 to 2020 were examined by age and histotype (seminoma vs. non-seminoma). The standardized incidence rate was calculated using the European population, and the annual percent change (APC) was reported. The five-year relative survival was estimated using the Pohar Perme method. The association with the second neoplasm was also evaluated. In our study, 385 patients with testicular cancer were included, most of whom were aged between 30 and 40 years. The non-seminoma and seminoma groups accounted for 44% and 18% of younger adults, respectively. The incidence rate increased during the study period (APC 1.6*); however, it increased in seminomas (APC 2.3*) but not in non-seminomas (APC -0.1). Conversely, the mortality rate remained constantly low either overall or in each of the two groups. The overall 5-year survival rate of testicular cancer patients was 95% (99% and 88% for seminomas and non-seminomas, respectively). Primary extratesticular tumors were documented in 37 cases, 18 after and 19 before the testicular cancer diagnosis. Our study confirms that the increased incidence and excellent survival rate are the prerogative of seminomas.

EUR UROL SUPPL 2023; 57:51-59. [PMID: 38020521 PMCID: PMC10658418 DOI: 10.1016/j.euros.2023.09.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/09/2023] [Indexed: 12/01/2023] Open
Abstract
Background Hypospadias is a common genital malformation among boys. Studies indicate that hypospadias is associated with a higher risk of testicular cancer. Other forms of urological cancer may be linked to hypospadias via a mutual aetiology, hormonal dysfunction, or hypospadias complications, but this has not yet been studied. Objective To investigate the association between hypospadias and testicular cancer and the risk of other urological cancers among individuals born with hypospadias. Design setting and participants The study used a population-based male cohort born in Sweden in 1964-2018. Exposure was hypospadias diagnosis in national registers. Outcomes were defined using the Swedish Cancer Register. An extended cohort born from 1940 was used to study cancers among older men. Biological brothers and fathers were linked to investigate familial coaggregation. Outcome measurements and statistical analysis Associations were assessed using Cox proportional-hazards regression analysis, with results presented as hazard ratios. Results and limitations We found that hypospadias was associated with a higher risk of testicular cancer (hazard ratio 2.04, 95% confidence interval 1.42-2.92), especially for proximal hypospadias, but did not observe any clear familial coaggregation of hypospadias and testicular cancer. Hypospadias was associated with Wilms' tumour in childhood. We also found an association between hypospadias and bladder and urethral cancers, but not prostate cancer. The number of cases with hypospadias was small and the results for cancers among older men may be impacted by limitations in register coverage. Conclusions Our study supports the hypothesis of a higher risk of testicular cancer for men with hypospadias, especially with proximal phenotypes. Hypospadias may also be associated with a higher risk of lower urinary tract cancers, although this requires further investigation in older cohorts. Patient summary Boys and men in whom the opening of the urethra is not at the end of the penis (called hypospadias) at birth are at higher risk of developing testicular cancer, although their overall risk is still low. They may also have a higher risk of developing other forms of cancer in the urinary tract.

Abstract
Extensive research showcases the extent and efficacy of humor-based messaging in general health promotion. However, the work describing humor's use within testicular cancer (TC) awareness is less developed. The aim of this comparative critical review was to determine the impact of using humor-based messaging in TC awareness campaigns to achieve a baseline assessment from which future research can be modeled. A literature search was conducted using seven databases to locate relevant literature. Three research questions guided this investigation: (1) To what extent has humor been used in TC awareness campaigns? (2) What does the literature reveal about the use of humor-based messaging on relevant health outcomes? (3) What are the limitations within current TC awareness strategies? Six studies were included in the review, of which three directly assessed the use of humor in TC awareness vis-à-vis intervention designs. Humor-based strategies were implemented to enhance knowledge of TC and testicular self-examination (TSE) procedures, reduce anxiety surrounding detection threat, and promote TSE. The rhetoric provided to men via various health interventions relied on humor and slang to promote TSE among males. Despite the small sample size of the included studies, this review determined that humor may be useful in reducing uncomfortable feelings surrounding TSE, increasing awareness of TC, and promoting TSE. When using humor-based messaging, however, the audience and type of humor implemented must be considered. Limited research exists assessing the long-term impact humor in TC promotion on health behavioral changes, easing anxieties related to detection, and increased self-efficacy surrounding TSE.

Abstract
Most genitourinary tract cancers have a negative impact on male fertility. Although testicular cancers have the worst impact, other tumors such as prostate, bladder, and penis are diagnosed early and treated in relatively younger patients in which couple fertility can be an important concern. The purpose of this review is to highlight both the pathogenetic mechanisms of damage to male fertility in the context of the main urological cancers and the methods of preserving male fertility in an oncological setting, in light of the most recent scientific evidence. A systematic review of available literature was carried out on the main scientific search engines, such as PubMed, Clinicaltrials.Gov, and Google scholar. Three hundred twenty-five relevant articles on this subject were identified, 98 of which were selected being the most relevant to the purpose of this review. There is a strong evidence in literature that all of the genitourinary oncological therapies have a deep negative impact on male fertility: orchiectomy, partial orchiectomy, retroperitoneal lymphadenectomy (RPLND), radical cystectomy, prostatectomy, penectomy, as well as radiotherapy, chemotherapy, and hormonal androgen suppression. Preservation of fertility is possible and includes cryopreservation, hormonal manipulation with GnRH analogs before chemotherapy, androgen replacement. Germ cell auto transplantation is an intriguing strategy with future perspectives. Careful evaluation of male fertility must be a key point before treating genitourinary tumors, taking into account patients' age and couples' perspectives. Informed consent should provide adequate information to the patient about the current state of his fertility and about the balance between risks and benefits in oncological terms. Standard approaches to genitourinary tumors should include a multidisciplinary team with urologists, oncologists, radiotherapists, psycho-sexologists, andrologists, gynecologists, and reproductive endocrinologists.

Abstract
OBJECTIVE The aim was to evaluate the causes of death for patients with testicular cancer (TC), and calculate mortality risks for each cause. METHODS Patients diagnosed between 2000 and 2017 were identified. Main causes of death including TC, second malignant tumor (SMT) and non-tumor diseases, and the standardized mortality rate (SMR) of each cause were analyzed. RESULTS 27,143 patients with localized TC were included, and 1171 of them died including 215 TC deaths, 236 SMT deaths, and 720 non-tumor deaths. Main SMT deaths were cancer from lung and bronchus, colon and rectum, etc. Main non-cancer causes were diseases of heart, accidents and adverse effects and suicide and self-inflicted injury. Compared with the general population, the mortality risks from diseases of heart and accidents and adverse effects were significantly reduced. For 11,719 patients with regional and distant metastasis TC, 1733 died including 964 TC deaths, 345 SMT deaths and 424 non-tumor deaths. The main SMT and non-tumor deaths were lung and bronchus, diseases of heart and suicide and self-inflicted injury. CONCLUSION The leading causes of death besides TC were lung and bronchus cancer, colon and rectum cancer, diseases of heart, accidents and adverse effects, suicide and self-inflicted injury for TC patients. The localized TC patients were associated with similar risks of SMT deaths and lower risks of main non-tumor causes of death. IMPACT We evaluated all causes of death of TC patients and SMR for each cause of death. Our results could provide valuable information about the priority of healthcare during testicular cancer survival.

Abstract
INTRODUCTION Testicular cancer is the most common cancer in men aged 15-44 years in many countries. Most men with testicular cancer present with a lump. Testicular symptoms are more likely to occur secondary to benign diseases like epididymo-orchitis, a common sexually transmitted infection. Gender and sexual minorities are at an increased risk of testicular diseases and health disparities. The aim of this study was to co-design an inclusive community-based campaign to promote testicular awareness. METHODS This study uses the World Café methodology. Participation was sought from Lesbian, Gay, Bisexual, Transgender and Queer+ friendly organisations, testicular cancer survivors, health policy makers, media and marketing experts and graphic designers. Participants engaged in three rounds of conversations to co-design the campaign. Data were collected using drawing sheets, artefact cards, sticky notes, coloured markers and a voice recorder. Deductive thematic analysis was conducted. RESULTS Seventeen individuals participated in the study. Six themes emerged from the analysis as follows: (i) online communication; (ii) offline communication; (iii) behavioural targeting and education; (iv) campaign frequency and reach; (v) demographic segmentation; and (vi) campaign identity. The use of social media for campaign delivery featured strongly in all conversations. Participants also recommended offline communication using posters and radio/television advertisements to scale up the campaign and achieve wider reach. Advertisements to overcome embarrassment surrounding testicular health were particularly recommended. Participants emphasised that campaign delivery must be dynamic whilst ensuring that the health-promoting messages are not diluted or lost. They stressed the importance of being inclusive and tailoring the campaign to different age groups, gender identities and sexual orientations. CONCLUSIONS Study recommendations will be used to design and deliver the campaign. Future research will be needed to evaluate the feasibility, acceptability, cost and effect of the campaign on promoting testicular awareness and early detection of testicular diseases. PATIENT OR PUBLIC CONTRIBUTION A participatory research approach was used to co-design the campaign with members of Lesbian, Gay, Bisexual, Transgender and Queer+ (LGBTQ+) friendly organisations, LGBTQ+ student bodies, LGBTQ+ staff networks, LGBTQ+ sports clubs, men's health organisations, testicular cancer survivors, health policy makers, media and marketing experts and graphic designers.

Abstract
Biomarkers are biomolecules used to identify or predict the presence of a specific disease or condition. They play an important role in early diagnosis and may be crucial for treatment. MicroRNAs (miRNAs), a group of small non-coding RNAs, are more and more regarded as promising biomarkers for several reasons. Dysregulation of miRNAs has been linked with development of several diseases, including many different types of cancer, and abnormal levels can be present in early stages of tumor development. Because miRNAs are stable molecules secreted and freely circulating in blood and urine, they can be sampled with little or no invasion. Here, we present an overview of the current literature, focusing on the types of cancers for which dysregulation of miR-665 has been associated with disease progression, recurrence, and/or prognosis. It needs to be emphasized that the role of miR-665 sometimes seems ambiguous, in the sense that it can be upregulated in one cancer type and downregulated in another and can even change during the progression of the same cancer. Caution is thus needed before using miR-665 as a biomarker, and extrapolation between different cancer types is not advisable. Moreover, more detailed understanding of the different roles of miR-665 will help in determining its potential as a diagnostic and prognostic biomarker.

Abstract
PURPOSE Normative male genital measurements are clinically useful and temporal changes would have important implications. The aim of the present study is to characterize the trend of worldwide penile length over time. MATERIALS AND METHODS A systematic review and meta-analysis using papers from PubMed, Embase, and Cochrane Library from inception to April 2022 was performed. PRISMA guidelines were used for abstracting data and assessing data quality and validity. Pooled means and standard deviations for flaccid, stretched, and erect length were obtained. Subgroup analyses were performed by looking at differences in the region of origin, population type, and the decade of publication. Metaregression analyses were to adjusted for potential confounders. RESULTS Seventy-five studies published between 1942 and 2021 were evaluated including data from 55,761 men. The pooled mean length estimates were flaccid length: 8.70 cm (95% CI, 8.16-9.23), stretched length: 12.93 cm (95% CI, 12.48-13.39), and erect length: 13.93 cm (95% CI, 13.20-14.65). All measurements showed variation by geographic region. Erect length increased significantly over time (QM=4.49, df=2, p=0.04) in several regions of the world and across all age groups, while no trends were identified in other penile size measurements. After adjusting for geographic region, subject age, and subject population; erect penile length increased 24% over the past 29 years. CONCLUSIONS The average erect penis length has increased over the past three decades across the world. Given the significant implications, attention to potential causes should be investigated.

[PMID: 37543714 PMCID: PMC10549230 DOI: 10.1002/2211-5463.13688] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Revised: 07/23/2023] [Accepted: 08/03/2023] [Indexed: 08/07/2023] Open
Abstract
Testicular germ cell tumors (TGCT) are the most common type of testicular cancer, comprising 90-95% of cases and representing the most prevalent solid malignancy in young adult men. Immune infiltrates play important regulatory roles in tumors, but their role in TGCT remains unclear. Molecular subtyping is a promising way to provide precisely personalized treatment and avoid unnecessary toxicities. This study investigated immune infiltrates, key biomarkers, and immune subtyping of TGCT. In GSE3218, 24 differentially expressed immune genes (immDEGs) were identified. A new risk signature consisting of six immDEGs was developed using these genes. Individuals in the high-risk group had poor overall survival (OS; hazard ratio of 4.61 and P-value < 0.001). We validated the six-immDEGs risk signature in pure seminoma and mixed TGCT types. Two distinct immune patterns (Cluster 1 and Cluster 2) were identified using the consensusclusterplus, and Cluster 1 possessed an unfavorable OS compared with Cluster 2 (hazard ratio, 2.56; P < 0.001). Cluster 1 patients had significantly lower naive B cells, memory B cells, plasma cells, naive CD4 T cells, gamma delta T cells, and activated dendritic cells than Cluster 2 patients. Genes relating to the WNT signaling pathway, TGF-β signaling pathway, antigen processing and presentation, and NK cell-mediated cytotoxicity were associated with TGCT. STC1 was elevated in TGCT tissues, and its high expression showed advanced clinicopathological characteristics and poor prognosis of TGCT. Our findings may contribute to an increased understanding of the onset and progression of TGCT.

Abstract
OBJECTIVE To elucidate clinical and demographic predictors of metastatic testicular cancer (TC) at presentation and study the impact of these factors on prognosis. Patients with metastatic TC experience poorer outcomes than those with localized or locoregional disease. Social determinants of health may compound this trend. METHODS The Surveillance, Epidemiology, and End Results (SEER) database was queried to identify 16,528 patients aged ≥18 with TC diagnosed from 2010 to 2016. Descriptive statistics were analyzed using Fisher exact test and Pearson chi-square test for continuous and categorical variables. Predictors of specific metastases and factors impacting cancer-specific mortality (CSM) were evaluated using multivariate logistic regression analysis and competing risks regression, respectively. RESULTS Of 16,474 patients with complete data, 1877 (11.39%) had distant metastases at diagnosis. These patients more commonly featured disease-specific and demographic variables associated with worse health outcomes (all P < .001). Lung metastases were the predominant site of synchronous and solitary metastases. Disease-specific predictors of metastasis included T stage, histology, tumor size, lymphovascular invasion, and cryptorchidism. Patient-specific predictors included age, geography, ethnicity, race, marital status, and socioeconomic status. Nearly one-fourth of patients with metastases died. Poor CSM was predicted by histology, age, insurance status, and socioeconomic status. All metastatic sites except bone were associated with worse CSM, with lung metastases conferring the greatest risk. CONCLUSION This cross-sectional study identifies variables associated with TC metastasis and survival, particularly highlighting the importance of social determinants of health in TC mortality. These findings can facilitate a risk-stratified approach to staging and management while supporting new approaches to target disparities.

Abstract
BACKGROUND Testicular malignancy is the most common solid organ cancer occurring in young men. The most common testicular malignancy is germ cell tumor. Extragonadal malignancies such as lymphomas are rare. Testicular fine-needle aspiration cytology (FNAC) in cancer is a bit controversial amidst fear of tumor seeding along the needle tract. Nevertheless, its largely safe, cost-effective technique providing a quick and fairly reliable diagnosis. METHODS A retrospective analysis of testicular malignancies on FNAC over a period of 9 years with cyto-histological correlation wherever possible was carried out. FNAC slides and cell blocks with immunocytochemistry wherever done were retrieved. RESULTS A total of 74 cases were obtained. The age ranged from 1 year to 65 years. Infiltration by leukemia was the most common malignancy detected in pediatric population, while germ cell tumors were common amongst young adults and middle-aged men. In elderly, metastatic carcinoma, infiltration by lymphoma were identified. On FNAC, 38 cases were of leukemic infiltration, 27 of germ cell tumors (subtyped as mixed germ cell tumors-15 cases, seminoma-11 cases, and yolk sac tumor-1 case) with two cases each of non-Hodgkin lymphoma, Leydig cell tumor, metastatic adenocarcinoma, and one case each of metastatic small cell carcinoma, rhabdomyosarcoma, and malignant neoplasm. Histological correlation was available in 15/74 cases. Only 3 cases were discordant. Seeding of tumor along the needle tract was not seen. CONCLUSION The current study deciphers the cytological spectrum of testicular malignancies on FNAC and highlights its importance as a reliable modality for a prompt diagnosis of testicular tumors guiding patient management.

Abstract
Ferroptosis is a type of programmed cell death mediated by iron-dependent lipid peroxidation that leads to excessive lipid peroxidation in different cells. Ferroptosis is distinct from other forms of cell death and is associated with various diseases. Iron is essential for spermatogenesis and male reproductive function. Therefore, it is not surprising that new evidence supports the role of ferroptosis in testicular injury. Although the molecular mechanism by which ferroptosis induces disease is unknown, several genes and pathways associated with ferroptosis have been linked to testicular dysfunction. In this review, we discuss iron metabolism, ferroptosis, and related regulatory pathways. In addition, we analyze the endogenous and exogenous factors of ferroptosis in terms of iron metabolism and testicular dysfunction, as well as summarize the relationship between ferroptosis and male reproductive dysfunction. Finally, we discuss potential strategies to target ferroptosis for treating male reproductive diseases and provide new directions for preventing male reproductive diseases.

Abstract
Malignant testicular germ cells tumors (TGCTs) are the most common solid cancers in young men. Current TGCT diagnostics include conventional serum protein markers, but these lack the sensitivity and specificity to serve as accurate markers across all TGCT subtypes. MicroRNAs (miRNAs) are small non-coding regulatory RNAs and informative biomarkers for several diseases. In humans, miRNAs of the miR-371-373 cluster are detectable in the serum of patients with malignant TGCTs and outperform existing serum protein markers for both initial diagnosis and subsequent disease monitoring. We previously developed a genetically engineered mouse model featuring malignant mixed TGCTs consisting of pluripotent embryonal carcinoma (EC) and differentiated teratoma that, like the corresponding human malignancies, originate in utero and are highly chemosensitive. Here, we report that miRNAs in the mouse miR-290-295 cluster, homologs of the human miR-371-373 cluster, were detectable in serum from mice with malignant TGCTs but not from tumor-free control mice or mice with benign teratomas. miR-291-293 were expressed and secreted specifically by pluripotent EC cells, and expression was lost following differentiation induced by the drug thioridazine. Notably, miR-291-293 levels were significantly higher in the serum of pregnant dams carrying tumor-bearing fetuses compared to that of control dams. These findings reveal that expression of the miR-290-295 and miR-371-373 clusters in mice and humans, respectively, is a conserved feature of malignant TGCTs, further validating the mouse model as representative of the human disease. These data also highlight the potential of serum miR-371-373 assays to improve patient outcomes through early TGCT detection, possibly even prenatally.

Abstract
Testicular germ cell tumours are the most common solid malignancies in young men of age 14-44 years. It is generally accepted that both seminomas and non-seminomas arise from a common precursor, the germ cell neoplasia in-situ, which itself is the result of a defective (primordial) germ cell development. The stem cell-like population of the non-seminomas, the embryonal carcinoma, is capable of the differentiation of all three germ layers (teratomas) and extra-embryonic tissues (yolk-sac tumours, choriocarcioma) into cells. In contrast, seminomas are thought to have a limited differentiation potential. Nevertheless, several studies have highlighted their ability to undergo reprogramming to an embryonal carcinoma or differentiation into other non-seminomatous entities. Here, we demonstrate that in approximately 5% of seminomas, the yolk-sac tumour driver gene FOXA2 is detectable at the protein level, indicative of an occult yolk-sac tumour subpopulation that putatively arose from seminoma cells, as the presence of other GCT entities could be excluded. The presence of these subpopulations might render the tumour more aggressive and argue for an adjustment of the therapeutic concept. We used our data to update the model of germ cell tumour pathogenesis, especially regarding the developmental potential of seminomas. Additionally, we suggest to include detection of FOXA2 into standard routine diagnosis of seminomas.

Abstract
Background Lung metastatic tumor (LM) is one of testicular germ cell tumors' most common metastatic sites. Our study aimed to develop a nomogram for predicting the risk of LM among patients with testicular germ cell tumors (TGCTs). Methods Clinicopathological information of 4078 patients with TGCT between 2010 and 2015 was obtained from SEER. Univariate and multivariate logistic regression analyses were performed to identify risk factors for LM, and a nomogram was developed based on these factors. Calibration curves, area under the receiver operating curve (AUC), and decision curve analysis (DCA) were used to evaluate the accuracy and discrimination of the model. Results Study participants included 4078 people with TGCTs, including 305 people with LM. They were randomly divided into two groups (training cohort = 2854 and validation cohort = 1224) at a ratio of 7:3. The following variables were incorporated in the nomogram: marital status, tumor histological type, T stage, brain metastasis, liver metastasis, lactate dehydrogenase (LDH), and chemotherapy. Besides, the AUC of it was 0.922 in the training cohort, while was 0.930 in the validation cohort. Training and validation cohort calibrations showed that the nomogram had excellent predictive abilities. DCA suggested it was more clinically relevant than the traditional TN staging. Conclusion We have established a nomogram to predict the risk of LM in patients with TGCTs. Doctors and patients can use this nomogram to monitor and identify lung metastasis of tumors through active monitoring and follow-up.

Abstract
Purpose This study's objective was to report cancer control and toxicity outcomes after proton radiation therapy (RT) in testicular seminoma and to compare secondary malignancy (SMN) risks with photon-based treatment alternatives. Methods and Materials Consecutive patients with stage I-IIB testicular seminoma treated with proton RT at a single institution were retrospectively analyzed. Kaplan-Meier estimates for disease-free and overall survival were computed. Toxicities were scored using Common Terminology Criteria for Adverse Events version 5.0. Photon comparison plans, including 3-dimensional conformal RT (3D-CRT) and intensity modulated RT (IMRT)/volumetric arc therapy (VMAT), were created for each patient. Dosimetric parameters and SMN risk predictions for different in-field organs-at-risk were compared between the techniques. Excess absolute SMN risks were estimated with organ equivalent dose modeling. Results Twenty-four patients were included (median age, 38.5 years). The majority of patients had stage II disease (IIA, 12 [50.0%]; IIB, 11 [45.8%]; IA, 1 [4.2%]). Seven (29.2%) and 17 (70.8%) patients had de novo and recurrent disease, respectively (de novo/recurrent: IA, 1/0; IIA, 4/8; IIB, 2/9). Most acute toxicities were mild (grade 1 [G1], 79.2%; G2, 12.5%) with G1 nausea being most common (70.8%). No serious events (G3-5) occurred. With a median follow-up time of 3 years (interquartile range, 2.1-3.6 years), 3-year disease-free and overall survival rates were 90.9% (95% confidence interval, 68.1%-97.6%) and 100% (95% confidence interval, 100%-100%), respectively. There were no documented late toxicities in the follow-up period, including worsening serial creatinine levels suggestive of early nephrotoxicity. Proton RT had significant reductions in mean organ-at-risk doses to the kidneys, stomach, colon, liver, bladder, and body compared with both 3D-CRT and IMRT/VMAT. Proton RT had significantly lower SMN risk predictions compared with 3D-CRT and IMRT/VMAT. Conclusions Cancer control and toxicity outcomes using proton RT in stage I-IIB testicular seminoma are consistent with existing photon-based RT literature. However, proton RT may be associated with significantly lower SMN risks.

Abstract
INTRODUCTION Artificial intelligence is transforming healthcare by driving innovation, automation, and optimization across various fields of medicine. The aim of this study was to determine whether artificial intelligence (AI) techniques can be used in the diagnosis, treatment planning, and monitoring of urological cancers. METHODOLOGY We conducted a thorough search for original and review articles published until 31 May 2022 in the PUBMED/Scopus database. Our search included several terms related to AI and urooncology. Articles were selected with the consensus of all authors. RESULTS Several types of AI can be used in the medical field. The most common forms of AI are machine learning (ML), deep learning (DL), neural networks (NNs), natural language processing (NLP) systems, and computer vision. AI can improve various domains related to the management of urologic cancers, such as imaging, grading, and nodal staging. AI can also help identify appropriate diagnoses, treatment options, and even biomarkers. In the majority of these instances, AI is as accurate as or sometimes even superior to medical doctors. CONCLUSIONS AI techniques have the potential to revolutionize the diagnosis, treatment, and monitoring of urologic cancers. The use of AI in urooncology care is expected to increase in the future, leading to improved patient outcomes and better overall management of these tumors.

Abstract
Testicular cancer is common in young men, and early detection and multimodality treatment can lead to successful outcomes. This study aims to identify sociodemographic and risk factors associated with higher testicular cancer mortality and poorer survival rates, while examining the impact of diagnostic and treatment procedures on reducing mortality. The retrospective ecological study analyzed mortality data from testicular cancer in Brazil from 2001 to 2020. Sociodemographic variables such as marital status, age, birth period, year of death (cohort), race, and geographic region were assessed. Risk factors included cryptorchidism and pesticide exposure. Data were subjected to statistical analysis, which revealed an increasing trend in mortality after 2011 among persons born after 1976 in the 15-40 age group. Individuals in the South Region, whites, and singles had higher age-standardized mortality rates (ASMRs), while singles had lower survival rates. The Northeast region had a higher survival rate. Fungicides and insecticides increase ASMR in Brazil. Herbicides increase ASMR in the Northeast and Midwest regions and insecticides increase ASMR in the Northeast, Southeast, and Midwest regions. High rates of implementation of diagnostic procedures in the Midwest were not sufficient to reduce ASMR. No treatment procedure was associated with mortality at the national or regional level.
