[PMID: 38166868 PMCID: PMC10763021 DOI: 10.1186/s12894-023-01386-4] [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: 06/03/2023] [Accepted: 12/04/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND There are few studies on cryptorchidism in adults, and its treatment is still controversial. METHODS To summarize the surgical strategy and clinical efficacy of laparoscopic orchidopexy for the treatment of cryptorchidism in adults, 37 adult cryptorchidism patients were retrospectively analyzed between September 2017 and February 2022. All 37 patients underwent laparoscopic orchidopexy, of whom 33 underwent inguinal hernia repair without tension. The intraoperative procedures and surgical techniques were recorded in detail. Preoperative examination and regular postoperative review of color Doppler ultrasound, and reproductive hormone, alpha-fetoprotein, human chorionic gonadotropin, and lactate dehydrogenase levels were performed. RESULTS All testes descended successfully into the scrotum, including 25 through the inguinal route and 12 through Hesselbach's triangle route. No intraoperative or postoperative complications were observed. The follow-up time was 38.6 (± 19.4) months, and no evidence of testicular malignancy was found during the follow-up period. After analyzing the reproductive hormone levels at 1 year postoperatively in 28 patients with more than 1 year of follow-up, it was found that the patients had a significant increase in testosterone levels and a decrease in follicle-stimulating hormone levels after surgery. None of the patients showed any significant improvement in semen quality after surgery. CONCLUSION Our study suggests that laparoscopic orchidopexy is a safe and feasible surgical procedure for the treatment of cryptorchidism in adults, especially high cryptorchidism, which is difficult to treat. After comprehensive consideration, preserving the testis should be preferred for treating cryptorchidism in adults to maximize the protection of the patient's reproductive hormone secretion function.

Abstract
Metabolic reprogramming is an emerging hallmark of cancer, involving the overexpression of metabolism-related proteins, such as glucose and monocarboxylate transporters and intracellular glycolytic enzymes. The biology of testicular germ cell tumors (TGCTs) is very complex, and although their metabolic profile has been scantily explored, some authors have recently reported that the metabolic rewiring of cancer cells resulted in an association with aggressive clinicopathological characteristics. In this study we have investigated, by immunohistochemical analysis, the expression of key proteins sustaining the hyperglycolytic phenotype in pure seminoma (SE, nr. 35), pure embryonal carcinoma (EC, nr. 17) tissues samples, and normal testes (nr. 5). GLUT1, CD44, PFK-1, MCT1, MCT4, LDH-A, and PDH resulted in more expression in EC cells compared to SE cells. TOM20 was more expressed in SE than in EC. GLUT1, MCT1, and MCT4 expression showed a statistically significant association with SE histology, while for EC, the association resulted in being significant only for GLUT1 and MCT4. Finally, we observed that EC resulted as negative for p53, suggesting that the GLUT1 and MTC overexpression observed in EC could be also attributed to p53 downregulation. In conclusion, our findings evidenced that EC exhibits a higher expression of markers of active aerobic glycolysis compared to SE, suggesting that the aggressive phenotype is associated with a higher glycolytic rate. These data corroborate the emerging evidence on the involvement of metabolic reprogramming in testicular malignancies as well, highlighting that the metabolic players should be explored in the future as promising therapeutic targets.

Histopathology and prognosis of germ cell tumors metastatic to brain: cohort study. J Neurooncol 2021; 154:121-130.

Abstract
INTRODUCTION Germ cell tumors (GCTs) are uncommon neoplasms predominantly arising in midline tissues. The prognostic significance of histopathology in predicting metastatic GCT behavior is poorly understood. METHODS Multicenter international cohort study including 29 patients with GCTs metastatic to brain were retrospectively investigated (18 patients from Mayo Clinic and 11 patients from the intracranial germ cell tumor genome analysis consortium in Japan). Clinical characteristics were analyzed using the Chi-square test (two-tailed) for categorical variables and using the log-rank test for survival data. RESULTS Median age at treatment was 31 years (range 14-58). Primary disease sites were testis (71%), mediastinum (18%), and female reproductive organs (11%). Median metastatic interval was 223 days (range, 6-6124). Median follow-up was 346 days (range, 1-5356), with 16 deaths (57%) occurring after the median overall survival of 455 days. Actuarial one-year survival was 51%; 12-of-16 deaths (75%) were attributed to intracranial disease. Appearance of the same GCT subtype at the metastatic site as the primary was high for non-seminomatous GCT (NSGCT, 64-100%), but low for seminoma/dysgerminoma and mature teratoma (MT, 14, 17%, respectively). Gain of a new component was seen in 4 (20%)-3 of which included embryonal carcinoma (EC) at the primary site (75%). Incidence of cases without seminoma/dysgerminoma increased significantly after metastasis (p = 0.02). Metastatic interval was shorter in cases with histological change (199 vs 454 days, p = 0.009). Overall survival was associated with MT primary histopathology (p = 0.02). CONCLUSION Histological differentiation at the primary GCT site influences metastatic prognosis. Aggressive behavior is associated with NSGCT, while EC frequently demonstrates multi-directional histological differentiation after brain metastasis, and such histological dynamism is associated with shorter metastatic interval. Most metastases occurred within one year of diagnosis, emphasizing the need for close surveillance in newly diagnosed extra-cranial GCT.

Abstract
Background Metabolic reprogramming is one of the hallmarks of cancer. The hyperglycolytic phenotype is often associated with the overexpression of metabolism-associated proteins, such as monocarboxylate transporters (MCTs). MCTs are little explored in germ cell tumors (GCTs), thus, the opportunity to understand the relevance of these metabolic markers and their chaperone CD147 in this type of tumor arises. The main aim of this study was to evaluate the expression of MCT1, MCT2, MCT4 and CD147 in testicular GCT samples and the clinicopathological significance of these metabolism related proteins. Results MCT1, MCT4 and CD147 were associated with higher stages, higher M and N stages and histological type, while MCT4 was also associated with higher risk stratification, presence of vascular invasion, and lower overall and event free survival. MCT4 silencing in JEG-3 had no significant effect in cell viability, proliferation and death, as well as extracellular levels of glucose and lactate. However, MCT4-silenced cells showed an increase in migration and invasion. Conclusion The proteins herein studied, with the exception of MCT2, were associated with characteristics of worse prognosis, lower global and event free survival of patients with GCTs. Also, in vitro MCT4 silencing stimulated cell migration and invasion. Materials and Methods Immunohistochemical expression was evaluated on samples from 149 adult patients with testicular GCT, arranged in Tissue Microarrays (TMAs), and associated with the clinicopathological data. Also, MCT4 silencing studies using siRNA were performed in JEG-3 cells.

Outcomes of surveillance versus adjuvant chemotherapy for patients with stage IA and IB nonseminomatous testicular germ cell tumors. World J Urol 2016; 35:1103-1110. [PMID: 27812752 DOI: 10.1007/s00345-016-1964-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2016] [Accepted: 10/26/2016] [Indexed: 10/20/2022] Open
Abstract
BACKGROUND Currently, it is accepted that risk assessment of clinical stage I (CS I) nonseminomatous germ cell tumors (NSGCT) patient is mainly dependent on the presence of lymphovascular invasion (LVI). Initial active surveillance, adjuvant chemotherapy and retroperitoneal lymph node dissection (RPLND) are acceptable treatment options for these patients, but there is no uniform consensus. The purpose of this study was to compare outcomes of active surveillance with adjuvant chemotherapy. METHODS A total of 201 patients with CS I NSGCT after orchiectomy were included. Outcomes of active surveillance and adjuvant chemotherapy were retrospectively analyzed. The prognostic significance of risk factors for survival and relapse was evaluated. RESULTS Of the 201 patients, 110 (54.7%) received adjuvant chemotherapy, while the remaining 91 patients (45.3%) underwent surveillance. Relapses were significantly higher for patients underwent surveillance compared to adjuvant chemotherapy group (18.3 vs. 1.2%, p < 0.001). The 5-year relapse-free survival (RFS) rate for patients who were treated with adjuvant chemotherapy was significantly better than those of patients underwent surveillance (97.6 vs. 80.8%, respectively; p < 0.001). Univariate analysis showed that the presence of LVI (p = 0.01) and treatment option (p < 0.001) were prognostic factors for RFS and pT stage (p = 0.004) and invasion of rete testis (p = 0.004) and the presence of relapse (p < 0.001) were significant prognostic factors for OS. Multivariate analysis revealed that the treatment strategy was an independent prognostic factor for RFS (p < 0.001, HR 0.54). A logistic regression analysis demonstrated that treatment options (p = 0.031), embryonal carcinoma (EC) >50% (p = 0.013) and tumor diameter (p = 0.016) were found to be independent factors for predicting relapse. CONCLUSIONS Our results indicate that adjuvant chemotherapy is associated with improved RFS compared with surveillance for CS I NSGCT patients. Moreover, the treatment strategy is an important prognostic indicator for RFS and a predictive factor for relapse. Although adjuvant chemotherapy seems to be a suitable treatment for patients with risk factors for relapse, surveillance is still preferred management option.

Abstract
BACKGROUND Germ cells are unique cells that possess the ability to transmit genetic information between generations. Detailed knowledge about the molecular and cellular mechanisms determining the fate of human male germ cells still remains sparse. This is partially due to ethical issues limiting the access to research material. Therefore, the mechanisms of proliferation, differentiation and apoptosis of human male germ cells still remain challenging study objectives. METHODS This review focuses on using English articles accessible in PubMed as well as personal files on the current knowledge of the molecular and cellular mechanisms connected with human testicular germ cell development, maturation failure and the possibility of fertility preservation in patients in whom there is a risk of gonadal failure. However, since rodents, particularly mice, offer the possibility of studying germ cell development by use of genetic modification techniques, some studies using animal models are also discussed. CONCLUSION This mini review focuses on the current knowledge about male germ cells. However, the reader is referred to two previous mini reviews focusing on testicular somatic cells, i.e. on Sertoli cells and Leydig cells.

Abstract
During the past few decades, scientific evidence has been accumulated concerning the possible adverse effects of the exposure to environmental chemicals on the well-being of wildlife and human populations. One large and growing group of such compounds of anthropogenic or natural origin is referred to as endocrine-disrupting chemicals (EDCs), due to their deleterious action on the endocrine system. This concern was first focused on the control of reproductive function particularly in males, but has later been expanded to include all possible endocrine functions. The present review describes the underlying physiology behind the cascade of developmental events that occur during sexual differentiation of males and the specific role of androgen in the masculinization process and proper organogenesis of the external male genitalia. The impact of the genetic background, environmental exposures and lifestyle factors in the etiology of hypospadias, cryptorchidism and testicular cancer are reviewed and the possible role of EDCs in the development of these reproductive disorders is discussed critically. Finally, the possible direct and programming effects of exposures in utero to widely use therapeutic compounds, environmental estrogens and other chemicals on the incidence of reproductive abnormalities and poor semen quality in humans are also highlighted.

Abstract
Objective. To meta-analyze published data about the diagnostic performance of fluorine-18-Fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) and PET/computed tomography (PET/CT) in the postchemotherapy management of patients with seminoma. Methods. A comprehensive literature search of studies published through January 2014 on this topic was performed. All retrieved studies were reviewed and qualitatively analyzed. Pooled sensitivity and specificity, positive and negative predictive values (PPV and NPV), accuracy, and area under the summary ROC curve (AUC) of 18F-FDG-PET or PET/CT on a per examination-based analysis were calculated. Subgroup analyses considering the size of residual/recurrent lesions were carried out. Results. Nine studies including 375 scans were selected. The pooled analysis provided the following results: sensitivity 78% (95% confidence interval (95% CI): 67–87%), specificity 86% (95% CI: 81–89%), PPV 58% (95% CI: 48–68%), NPV 94% (95% CI: 90–96%), and accuracy 84% (95% CI: 80–88%). The AUC was 0.90. A better diagnostic accuracy of 18F-FDG-PET or PET/CT in evaluating residual/recurrent lesions >3 cm compared to those <3 cm was found. Conclusions. 18F-FDG-PET and PET/CT were demonstrated to be accurate imaging methods in the postchemotherapy management of patients with seminoma; nevertheless possible sources of false-negative and false-positive results should be considered. The literature focusing on this setting still remains limited and cost-effectiveness analyses are warranted.
