Abstract
AIMS To resolve the ongoing controversy surrounding the impact of teratoma (TER) in the primary among patients with metastatic testicular non-seminomatous germ-cell tumours (NSGCT). PATIENTS AND METHODS Using the International Germ Cell Cancer Collaborative Group (IGCCCG) Update Consortium database, we compared the survival probabilities of patients with metastatic testicular GCT with TER (TER) or without TER (NTER) in their primaries corrected for known prognostic factors. Progression-free survival (5y-PFS) and overall survival at 5 years (5y-OS) were estimated by the Kaplan-Meier method. RESULTS Among 6792 patients with metastatic testicular NSGCT, 3224 (47%) had TER in their primary, and 3568 (53%) did not. In the IGCCCG good prognosis group, the 5y-PFS was 87.8% in TER versus 92.0% in NTER patients (p = 0.0001), the respective 5y-OS were 94.5% versus 96.5% (p = 0.0032). The corresponding figures in the intermediate prognosis group were 5y-PFS 76.9% versus 81.6% (p = 0.0432) in TER and NTER and 5y-OS 90.4% versus 90.9% (p = 0.8514), respectively. In the poor prognosis group, there was no difference, neither in 5y-PFS [54.3% in TER patients versus 55.4% (p = 0.7472) in NTER], nor in 5y-OS [69.4% versus 67.7% (p = 0.3841)]. NSGCT patients with TER had more residual masses (65.3% versus 51.7%, p < 0.0001), and therefore received post-chemotherapy surgery more frequently than NTER patients (46.8% versus 32.0%, p < 0.0001). CONCLUSION Teratoma in the primary tumour of patients with metastatic NSGCT negatively impacts on survival in the good and intermediate, but not in the poor IGCCCG prognostic groups.

Abstract
BACKGROUND Approximately 30% of patients with clinical stage I non-seminoma (CSI-NS) relapse. Current risk stratification is based on lymphovascular invasion (LVI) alone. The extent to which additional tumor characteristics can improve risk prediction remains unclear. OBJECTIVE To determine the most important prognostic factors for relapse in CSI-NS patients. DESIGN, SETTING, AND PARTICIPANTS Population-based cohort study including all patients with CSI-NS diagnosed in Denmark between 2013 and 2018 with follow-up until 2022. Patients were identified in the prospective Danish Testicular Cancer database. By linkage to the Danish National Pathology Registry, histological slides from the orchiectomy specimens were retrieved. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Histological slides were reviewed blinded to the clinical outcome. Clinical data were obtained from medical records. The association between prespecified potential prognostic factors and relapse was assessed using Cox regression analysis. Model performance was evaluated by discrimination (Harrell's C-index) and calibration. RESULTS Of 453 patients included, 139 patients (30.6%) relapsed during a median follow-up of 6.3 years. Tumor invasion into the hilar soft tissue of the testicular hilum, tumor size, LVI and embryonal carcinoma were independent predictors of relapse. The estimated 5-year risk of relapse ranged from < 5% to > 85%, depending on the number of risk factors. After internal model validation, the model had an overall concordance statistic of 0.75. Model calibration was excellent. CONCLUSION AND RELEVANCE The identified prognostic factors provide a much more accurate risk stratification than current clinical practice, potentially aiding clinical decision-making.

Abstract
BACKGROUND Historic evidence suggests that non-Caucasian race/ethnicity predisposes to higher testis cancer-specific mortality (CSM) in non-seminoma. However, it is unknown, whether higher CSM in non-Caucasians applies to Hispanics or Asians or African-Americans, or all of the above groups. In contemporary patients, we tested whether CSM is higher in these select non-Caucasian groups than in Caucasians, in overall and in stage-specific comparisons: stage I vs. stage II vs. stage III. METHODS The Surveillance, Epidemiology, and End Results (SEER) database (2004 -2019) was used. Kaplan-Meier plots and multivariable Cox regression models tested the effect of race/ethnicity on CSM after stratification for stage (I vs. II vs. III) and adjustment for prognosis groups in stage III. RESULTS In all 13,515 non-seminoma patients, CSM in non-Caucasians was invariably higher than in Caucasians. In stage-specific analyses, race/ethnicity represented an independent predictor of CSM in Hispanics in stage I (HR 1.8, p = 0.004), stage II (HR 2.2, p = 0.007) and stage III (HR 1.4, p < 0.001); in African-Americans in stage I (HR 3.2; p = 0.007) and stage III (HR 1.5; p = 0.042); and in Asians in only stage III (HR 1.6, p = 0.01). CONCLUSIONS In general, CSM is higher in non-Caucasian non-seminoma patients. However, the CSM increase differs according to non-Caucasian race/ethnicity groups. Specifically, higher CSM applies to all stages of non-seminoma in Hispanics, to stages I and III in African-Americans and only to stage III in Asians. These differences are important for individual patient management, as well as for design of prospective trials.

Abstract
Testicular germ cell tumors (TGCTs) are a common malignancy occurring in young adult men. The various genetic risk factors have been suggested to contribute to TGCT pathogenesis, however, they have a distinct mutational profile with a low rate of somatic point mutations, more frequent chromosomal gains, and aneuploidy. The most frequently mutated oncogenes in human cancers are RAS oncogenes, while their impact on testicular carcinogenesis and refractory disease is still poorly understood. In this mini-review, we summarize current knowledge on genetic alternations of RAS signaling-associated genes (the single nucleotide polymorphisms and point mutations) in this particular cancer type and highlight their link to chemotherapy resistance mechanisms. We also mention the impact of epigenetic changes on TGCT progression. Lastly, we propose a model for RAS-dependent signaling networks, regulation, cross-talks, and outcomes in TGCTs.

Abstract
We present the case of a 31-year-old male patient with non-seminoma (90% embryonal carcinoma, 10% teratoma) pT1b L1 V0 Pn0 R0 cN2 cM0, Clinical Stage IIb and "good prognosis group" according to IGCCCG of the left testis. According to EAU guidelines, he received three cycles of BEP. After the second cycle, he developed recurrent, clinically not significant rectal bleeding, which we associated with deep thrombocytopenia. Following chemotherapy, there was one lymph node in the CT scan left, with a diameter of 0.9 cm at the inferior mesenteric arteria and the rectal bleeding did not stop; so coloscopy and staging revealed rectal cancer (adenocarcinoma) with peritoneal carcinosis. The patient was scheduled for radio-chemotherapy. Next-generation sequencing of the adenocarcinoma showed two mutations in KRAS and TP53 genes. To our knowledge, this is the first case of non-seminoma and coincidental rectal cancer. Furthermore, this case underlines the significance of molecular biological studies for the development of individualized targeted therapies, especially in younger patients and in chemo- and/or platin-resistance.

Abstract
A 35-year-old man was diagnosed with stage IIIC non-seminoma with paralysis of the lower half of his body due to 8th thoracic spine metastasis. The patient received bleomycin, etoposide, and cisplatin (BEP) therapy. On day 4 of the second course of BEP, the patient developed a fever and was diagnosed with coronavirus disease (COVID-19). COVID-19 was suspected to worsen because of cancer and chemotherapy-induced immunosuppression. However, the benefits of continuing BEP therapy outweighed these risks. After obtaining fully informed consent, BEP therapy was continued from day 5, while sotrovimab (anti-COVID-19 drug) was administered. The second course of BEP was completed without worsening severe COVID-19 or bleomycin-induced lung injury. The patient completed four courses of BEP, with normalization of tumor markers, partial response on imaging, and improvement in lower body paralysis. In this case, we successfully treated a patient with testicular germ cell tumor with chemotherapy while having COVID-19 without treatment delay. During the COVID-19 pandemic, concomitant chemotherapy and COVID-19 treatment are warranted because delaying treatment will decrease the efficacy of highly curative diseases such as germ cell tumors.

Abstract
PURPOSE To present the current evidence and the development of studies in recent years on the management of extragonadal germ cell tumors (EGCT). METHODS A systematic literature search was conducted in Medline and the Cochrane Library. Studies within the search period (January 2010 to February 2021) that addressed the classification, diagnosis, prognosis, treatment, and follow-up of extragonadal tumors were included. Risk of bias was assessed and relevant data were extracted in evidence tables. RESULTS The systematic search identified nine studies. Germ cell tumors (GCT) arise predominantly from within the testis, but about 5% of the tumors are primarily located extragonadal. EGCT are localized primarily mediastinal or retroperitoneal in the midline of the body. EGCT patients are classified according to the IGCCCG classification. Consecutively, all mediastinal non-seminomatous EGCT patients belong to the "poor prognosis" group. In contrast mediastinal seminoma and both retroperitoneal seminoma and non-seminoma patients seem to have a similar prognosis as patients with gonadal GCTs and metastasis at theses respective sites. The standard chemotherapy regimen for patients with a EGCT consists of 3-4 cycles (good vs intermediate prognosis) of bleomycin, etoposid, cisplatin (BEP); however, due to their very poor prognosis patients with non-seminomatous mediastinal GCT should receive a dose-intensified or high-dose chemotherapy approach upfront on an individual basis and should thus be referred to expert centers Ifosfamide may be exchanged for bleomycin in cases of additional pulmonary metastasis due to subsequently planned resections. In general patients with non-seminomatous EGCT, residual tumor resection (RTR) should be performed after chemotherapy. CONCLUSION In general, non-seminomatous EGCT have a poorer prognosis compared to testicular GCT, while seminomatous EGGCT seem to have a similar prognosis to patients with metastatic testicular seminoma. The current insights on EGCT are limited, since all data are mainly based on case series and studies with small patient numbers and non-comparative studies. In general, systemic treatment should be performed like in testicular metastatic GCTs but upfront dose intensification of chemotherapy should be considered for mediastinal non-seminoma patients. Thus, EGCT should be referred to interdisciplinary centers with utmost experience in the treatment of germ cell tumors.

Abstract
Purpose Clinical stage I (CSI) testicular germ cell tumors (TGCT) represents disease confined to the testis without metastasis and CSIS is defined as persistently elevated tumor markers (TM) after orchiectomy, indicating subclinical metastatic disease. This study aims at assessing clinical characteristics and oncological outcome in CSIS. Methods Data from five tertiary referring centers in Germany were screened. We defined correct classification of CSIS according to EAU guidelines. TM levels, treatment and relapse-free survival were assessed and differences between predefined groups (chemotherapy, correct/incorrect CSIS) were analyzed with Fisher’s exact and Chi-square test. Results Out of 2616 TGCT patients, 43 (1.6%) were CSIS. Thereof, 27 were correctly classified (cCSIS, 1.03%) and 16 incorrectly classified (iCSIS). TMs that defined cCSIS were in 12 (44.4%), 10 (37%), 3 (11.1%) and 2 (7.4%) patients AFP, ß-HCG, AFP plus ß-HCG and LDH, respectively. In the cCSIS group, six patients were seminoma and 21 non-seminoma. Treatment consisted of active surveillance, carboplatin-mono AUC7 and BEP (bleomycin, etoposide and cisplatin). No difference between cCSIS and iCSIS with respect to applied chemotherapy was found (p = 0.830). 5-year relapse-free survival was 88.9% and three patients (11%) in the cCSIS group relapsed. All underwent salvage treatment (3xBEP) with no documented death. Conclusion Around 1% of all TGCT were classified as cCSIS patients. Identification of cCSIS is of critical importance to avoid disease progression and relapses by adequate treatment. We report a high heterogeneity of treatment patterns, associated with excellent long-term survival irrespective of the initial treatment approach.

Abstract
Background To date, the prognostic value of laterality for testicular germ cell tumors remains unknown. Herein, we describe this prognostic factor in the Mexican population. Methods A retrospective single-center study that included 37 patients with primary testicular germ cell tumors was conducted. Primary outcome was recurrence-free survival (RFS) at 2 years. Secondary outcomes were RFS by histology, progression-free survival by laterality, and 2-year overall survival. Results Thirty-seven patients were included, of which five showed relapses. By laterality, the 2-year RFS rate was 100% for left tumors and 77.3% for right tumors, with a trend toward statistical significance (P = 0.058). By histology, the RFS rate was higher for seminomas than non-seminomas (89% vs. 83%, respectively) without this difference being statistically significant. Progression-free survival was higher for right tumors than left tumors (91% vs. 80%, respectively) but without reaching statistical significance. The overall survival rate for the entire cohort was 94.5%. Conclusions Our study shows that patients with primary germ cell tumors of the right testicle have a higher risk of recurrence than those with primary germ cell tumors of the left testicle, with a trend toward statistical significance.

Abstract
PURPOSE One of the main issues in testicular germ cell tumors (TGCTs) management is to reduce the necessary amount of treatment to achieve cure. Excess treatment burden may arise from late diagnosis of the primary as well as from false positive or negative staging results. Correct imaging is of paramount importance for successful management of TGCT. The aim of this review is to point out the current state of the art as well as innovative developments in TGCT imaging on the basis of three common challenging clinical situations. METHODS A selective literature search was performed in PubMed, Medline as well as in recent conference proceedings. RESULTS Regarding small testicular lesions, recent studies using elastography, contrast-enhanced ultrasound or magnetic resonance imaging (MRI) showed promising data for differentiation between benign and malignant histology. For borderline enlarged lymph nodes FDG-PET-CT performance is unsatisfactory, promising new techniques as lymphotropic nanoparticle-enhanced MRI is the subject of research in this field. Regarding the assessment of postchemotherapeutic residual masses, the use of conventional computerized tomography (CT) together with serum tumor markers is still the standard of care. To avoid overtreatment in this setting, new imaging modalities like diffusion-weighted MRI and radiomics are currently under investigation. For follow-up of clinical stage I TGCTs, the use of MRI is non-inferior to CT while omitting radiation exposure. CONCLUSION Further efforts should be made to refine imaging for TGCT patients, which is of high relevance for the guidance of treatment decisions as well as the associated treatment burdens and oncological outcomes.

Abstract
INTRODUCTION The active surveillance (AS) of testicular tumors (seminoma and non-seminoma) is the most frequent management option in the stage I disease. Relapses generally occurred within the first 3 years and <5% appear after this time cut-off point is fulfilled. Therefore, the adherence is one of the most important pillars in the AS protocol. The aim of this study is to evaluate the adherence to the AS protocol in a community hospital and, in turn, evaluate the safety of it emphasizing in the relapse-free rate in patients with and without risk factors. MATERIALS AND METHODS A retrospective study of all the patients included in the AS protocol with seminoma tumors (ST) or non-seminoma tumors (NST) stage I was performed. Postoperative controls were performed according to the NCCN (National Comprehensive Cancer Network) recommendations. Different variables were taken into account, emphasizing in the risk factors: testicular tumor >4cm and the rete testis invasion in the ST, the linfovascular invasion and the percentage>40% of embrionary carcinoma in the NST. Adherence to the AS protocol was evaluated, focusing on those patients who lost it and what time it occurred. RESULTS A total of 64 patients were included. The median follow-up was 36 months (IC 21-48 months). 12 patients lost the follow-up during the protocol with a median follow-up of 27.5 months (IC 16-30 months). A 21.8% of patients entered in the AS protocol with some associated risk factor. Adherence follow-up was successful in the first year (96.8%) and decreased over time (92.2% at 24 months and 86.3% at 36 months). CONCLUSION We presented an important adherence to the AS protocol in patients with clinical stage I testicular cancer and in our series there no recurrences after 36 months of follow-up.

Abstract
OBJECTIVES We developed the first German evidence- and consensus-based clinical guideline on diagnosis, treatment, and follow-up of germ cell tumours (GCT) of the testes in adult patients. We present the guideline content in 2 separate publications. The present second part summarizes therecommendations for the treatment of advanced disease stages and for the management of follow-up and late effects. MATERIALS AND METHODS An interdisciplinary panel of 42 experts including 1 patient representative developed the guideline content. Clinical recommendations and statements were based on scientific evidence and expert consensus. For this purpose, evidence tables for several review questions, which were based on systematic literature searches (last search in March 2018), were provided. Thirty-one experts, who were entitled to vote, rated the final clinical recommendations and statements. RESULTS Here we present the treatment recommendations separately for patients with metastatic seminoma and non-seminomatous GCT (stages IIA/B and IIC/III), for restaging and treatment of residual masses, and for relapsed and refractory disease stages. The recommendations also cover extragonadal and sex cord/stromal tumours, the management of follow-up and toxicity, quality-of-life aspects, palliative care, and supportive therapy. CONCLUSION Physicians and other medical service providers who are involved in the diagnostics, treatment, and follow-up of GCT (all stages, outpatient and inpatient care as well as rehabilitation) are the users of the present guideline. The guideline also comprises quality indicators for measuring the implementation of the guideline recommendations in routine clinical care; these data will be presented in a future publication.

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

Abstract
Purpose Treatment of metastatic germ cell cancer (GCC) is based on the International Germ Cell Cancer Collaborative Group (IGCCCG) prognostic classification published in 1997. 5-year survival rates were reported to be 91%, 79%, and 48% for patients with good, intermediate and poor prognosis, respectively. However, treatment results may have improved over time due to cumulative experience, improved supportive care and modern-type chemotherapy. Methods Patients with metastatic GCC who received cisplatin-based chemotherapy at two institutions in Munich between 2000 and 2013 were retrospectively studied. Clinical characteristics, treatment and outcomes were analyzed with respect to the IGCCG prognostic classification. Results Of 225 patients (median age 35 years), 72 (32%) had seminoma (S) and 153 (68%) nonseminoma. 175 (78%), 30 (13%) and 20 patients (9%) had good, intermediate and poor prognosis according to the IGCCCG classification. The 2-year-progression free survival of patients with good, intermediate and poor prognosis was 91%, 83% and 37%, and the 5-year-overall survival (OS) was 98%, 96%, and 66%, respectively. There was no significant difference in the OS between patients in the good and intermediate prognosis group. Conclusion Compared to data from the original IGCCCG classification system, the outcome of patients with metastatic GCC has considerably improved over time. While the prognosis of intermediate-risk patients is excellent, treatment in the poor-prognosis group remains to be improved.

Abstract
Seminomatous (SGCT) and non-seminomatous (NSGCT) germ cell tumors (GCT) are rare but their incidence are increasing. We will discuss different therapeutic strategies in relapse disease: patients with stage I germ cell tumor have an excellent prognosis with a cure rate approaching 98-99 %, whatever the histology and the chosen treatment (surveillance strategy or adjuvant treatment). Relapses are observed among 20% of patients with stage I SGCT or low risk NSGCT and 50 % of patients with high risk NSGCT. Patients are treated according to the international prognosis group (IGCCCG) for SGCT and low risk NSGCT, naïve of chemotherapy. After an adjuvant treatment, the protocol must be adapted to the number of previous cycles (1 or 2 BEP) and to the prognosis group. Five to 50% of patients relapse after a first line of metastatic chemotherapy according to initial prognosis group. Dose-dense chemotherapy according to the GETUG13 protocol reduces the risk of relapse for the patients with poor-risk group NSGCT and unfavorable tumor marker decline. The prognosis of patients with relapsed or refractory GCT after a first line is more negative since only half of them will be cured by salvage standard chemotherapy. An international therapeutic trial (TIGER) is ongoing in first line salvage treatment evaluating high-dose chemotherapy (HDCT) with hematopoietic stem cell transplantation (HSCT). Finally, developing biomarkers for predicting clinical relapse, the management in expert centers of these patients and participation in therapeutic innovation are important perspectives for a better understanding and treatment of these patients with a poorer prognosis.

Abstract
PURPOSE OF REVIEW The purpose of this review is to educate medical oncologists on the management of patients with residual germ cell tumors and the role of surgical resection after platinum-based chemotherapy. RECENT FINDINGS Patients with non-seminomatous testicular cancer and residual enlarged retroperitoneal lymph nodes > 1 cm following induction chemotherapy with normal tumor markers should undergo a post-chemotherapy retroperitoneal lymph node dissection. All patients with primary mediastinal non-seminoma should undergo surgical resection of the mediastinal mass post-chemotherapy. These are complex surgeries and require expert surgeons in high-volume centers. Patients with advanced testicular seminoma who have residual masses less than 3 cm after chemotherapy can be observed without further intervention. Patients with a residual mass > 3 cm should be evaluated with PET scan after 6 weeks of chemotherapy. Residual mass with negative PET scan can be followed by surveillance while a positive PET scan requires further work up to rule out active disease.

Abstract
Purpose Patients with non-seminoma testicular cancer (NSTC) cancer can be subfertile or infertile, and present reduced sperm quality, but the underlying mechanisms are unknown. The aim of this study was to compare the sperm proteome of patients with NSTC, who cryopreserved their sperm before starting cancer treatment, with that from healthy fertile men. Materials and Methods Semen volume, sperm motility and sperm concentration were evaluated before the cryopreservation of samples from patients with NSTC (n=15) and the control group (n=15). Sperm proteomic analysis was performed by liquid chromatography-tandem mass spectrometry and the differentially expressed proteins (DEPs) between the two groups were identified using bioinformatic tools. Results A total of 189 DEPs was identified in the dataset, from which five DEPs related to sperm function and fertilization were selected for validation by Western blot. We were able to validate the underexpression of the mitochondrial complex subunits NADH:Ubiquinone Oxidoreductase Core Subunit S1 (NDUFS1) and ubiquinol-cytochrome C reductase core protein 2 (UQCRC2), as well as the underexpression of the testis-specific sodium/potassium-transporting ATPase subunit alpha-4 (ATP1A4) in the NSTC group. Conclusions Our results indicate that sperm mitochondrial dysfunction may explain the observed decrease in sperm concentration, total sperm count and total motile count in NSTC patients. The identified DEPs may serve as potential biomarkers for the pathophysiology of subfertility/infertility in patients with NSTC. Our study also associates the reduced fertilizing ability of NSTC patients with the dysregulation of important sperm molecular mechanisms.

Abstract
BACKGROUND Cancer-specific survival for patients with clinical stage I (CSI) germ cell testicular cancer (GCTC) is outstanding after inguinal orchidectomy regardless the treatment utilized. This study evaluated whether active surveillance (AS) of such patients yielded similar health outcomes to other therapeutic strategies such as adjuvant chemotherapy, radiotherapy or primary retroperitoneal lymphadenectomy as described in the literature. PATIENTS AND METHODS Patients with CSI GCTC were screened between January 2012 and December 2016. Patients had previously undergone inguinal orchidectomy as the primary treatment and chosen AS as their preferred management strategy after receiving information about all available strategies. RESULTS Out of 91 patients screened, 82 patients selected AS as their preferred management strategy. Relapse rate in the overall population was 20% (95% CI 12-30) and median time to relapse was 11.5 months (range 1.0-35.0). In patients with seminomatous tumors, relapse rate decreased to 13% and median time to relapse was 13 months; whereas in patients with non-seminomatous tumors, relapse rate was 33% (IA) or 29% (IB) and median time to relapse was 12 months in stage IA and 4.5 months in stage IB patients. All relapses were rescued with three or four cycles of chemotherapy and two also required a retroperitoneal lymphadenectomy. All patients are currently alive and free of disease. CONCLUSIONS The clinical outcomes of patients with CSI GCTC managed by AS in this series were excellent. This strategy limited the administration of active treatments specifically to the minority of patients who relapsed without compromising performance.

Abstract
Testicular cancer is a rare urological malignancy with high cure rate. The development of highly effective systemic treatment regimens along with advances in surgical treatment of advanced disease has led to continued improvement in outcomes. Patients with testicular cancer who are treated following the treatment guideline mostly achieved high quality of life and long-term survival. However, patients who were identified as having non-guideline directed care were at significantly higher risk of relapse. In this book chapter, we introduce in depth the modern management of testicular cancer, including diagnosis, staging and risk stratification, treatment strategies of seminoma and non-seminoma germ cell tumors, follow-up protocols, and salvage treatment for disease relapse. We also review new studies and updates on medical and surgical management of advanced testicular cancer.

Abstract
INTRODUCTION In 1979, the Copenhagen group around Dr. Skakkebaek introduced contralateral biopsy in patients with testicular germ cell tumour (GCT) as a means of early diagnosing a contralateral testicular tumour (Berthelsen et al. in Br Med J 2(6186):363-364, 1). Although the rationale of contralateral biopsies is based on much of scientific evidence, no issue regarding the management of GCTs has been more controversial than the issue of contralateral biopsies (Heidenreich in BJU Int 104(9 Pt B):1346-1350, 2; Grigor and Rorth in Eur Urol 23(1):129-135, 3). A poll conducted during the GCT Consensus Meeting in Berlin 2011 revealed that 43 % of 60 leading experts would not recommend a contralateral biopsy and only 13.7 % would do the biopsy in all cases with GCT (Beyer et al. in Ann Oncol 24(4):878-888, 4). Likewise, the European Association of Urology and the European Society of Medical Oncology offer only weak recommendations with respect to contralateral biopsies in their guidelines of testicular cancer (Albers et al. in Eur Urol 68(6):1054-1068, 5; Oldenburg et al. in Ann Oncol 24(Suppl 6):vi125-vi132, 6). CONCLUSION This review summarizes contemporary knowledge regarding contralateral biopsies to provide professionals caring for GCT patients with sufficient information to decide for or against the procedure in clinical practice.

Abstract
Increased levels of metallothionein (MT) have recently been found in the blood serum of men with newly diagnosed testicular germ cell tumors (TGCT). In light of previously published results, the aim of this study was to investigate the difference in serum MT levels among patients with different stages of TGCT and compare MT with commonly used markers (α-fetoprotein, β-human chorionic gonadotropin and lactate dehydrogenase). The concentration of total MT was determined in the serum of 25 men with TGCT (seminoma or non-seminoma) by differential pulse voltammetry. Serum samples were obtained prior to chemotherapy, after two cycles of chemotherapy and 1 year after chemotherapy. A statistically significant difference in MT levels in patients with different stages of TGCT was observed in the serum of patients with non-seminoma obtained before chemotherapy. Although not significant, an increase in serum MT levels commensurate with the disease stage increase was also observed in patients with seminomatous TGCT. The results indicate that, in combination with the existing markers, MT could be useful for the identification of the histological type of tumor and stage of the disease before biopsy diagnosis.

Abstract
Germ cell tumors (GCTs) are malignant cancers that arise from embryonic precursors known as Primordial Germ Cells. GCTs occur in neonates, children, adolescents and young adults and can occur in the testis, the ovary or extragonadal sites. Because GCTs arise from pluripotent cells, the tumors can exhibit a wide range of different histologies. Current cisplatin-based combination therapies cures most patients, however at the cost of significant toxicity to normal tissues. While GWAS studies and genomic analysis of human GCTs have uncovered somatic mutations and loci that might confer tumor susceptibility, little is still known about the exact mechanisms that drive tumor development, and animal models that faithfully recapitulate all the different GCT subtypes are lacking. Here, we summarize current understanding of germline development in humans and zebrafish, describe the biology of human germ cell tumors, and discuss progress and prospects for zebrafish GCT models that may contribute to better understanding of human GCTs.

Abstract
OBJECTIVE To assess the efficacy, outcome and complications of post-chemotherapy laparoscopic retroperitoneal lymph node dissection (L-RPLND) for stage IIA/B testicular germ cell tumor (GCT) patients in comparison with open RPLND (O-RPLND). METHODS L-RPLND was performed in 14 patients with stage IIA/B non-seminoma GCTs among 154 non-seminoma patients who received RPLND after completion of chemotherapy with tumor marker normalization at our institution between 1998 and 2013. Their outcomes were compared with those of 14 patients with stage IIA/B non-seminoma GCTs treated with O-RPLND during the same period. Clinical parameters were compared between L-RPLND and O-RPLND. RESULTS There were no significant differences in the background characteristics of the two groups except for follow-up duration (36 months for L-RPLND, 70 months for O-RPLND; p = 0.02). Blood loss during surgery was significantly less for the L-RPLND group than for the O-RPLND group (155 mL for L-RPLND, 700 mL for O-RPLND; p < 0.001). Parameters related to post-operative recovery were significantly better for the L-RPLND group than for the O-RPLND group. Histopathological examination showed no difference between the two groups. Neither group had disease recurrence. CONCLUSION Post-chemotherapy L-RPLND with a bilateral template and nerve-sparing method was safe, effective, and showed a high preservation rate of antegrade ejaculation with no deterioration of outcomes compared to O-RPLND.

Abstract
AIM: To investigate the expression of programmed cell death 4 (Pdcd4) tumor suppressor gene in tissue specimen of renal cell carcinoma (RCC), testicular germ cell cancer and penile cancer.
METHODS: Pdcd4 expression was studied using immunohistochemistry in 188 cases of RCC and 28 controls (including 9 oncocytoma); in 74 cases of penile carcinoma (including 17 metastatic tissue samples) and 26 controls; in 11 cases of seminoma, in 14 cases of non-seminoma and 5 controls.
RESULTS: Control tissues exhibited strong core and cytoplasmatic Pdcd4 staining. In contrast, core and cytoplasmatic Pdcd4 levels were significantly decreased in cancer tissues.
CONCLUSION: Our data support a role for Pdcd4 (down-) regulation in urologic tumors. Interestingly, Pdcd4 expression seem to be a potential diagnostic marker for renal or penile tumors.

Abstract
Testicular neoplasm accounts for about 1% of all cancers in men. Over the last 40 years, the incidence of testicular cancer has increased in northern European male populations for unknown reasons. When diagnosed at early stage, testicular cancer is usually curable with a high survival rate. In the past three decades, successful multidisciplinary approaches for the management of testicular cancer have significantly increased patient survival rates. Utilization of tumor markers and accurate prognostic classification has also contributed to successful therapy. In this article, we highlight the most commonly used tumor markers and several potential "novel" markers for testicular cancer as part of the ongoing effort in biomarker research and discovery. In addition, this article also identifies several key prognostic features that have been demonstrated to play a role in predicting relapse. These features include tumor size, rete testis invasion, lymphovascular invasion, and tumor histology. Together with tumor markers, these prognostic factors should be taken into account for risk-adapted management of testicular cancer.

Abstract
Extragonadal germ cell tumors are rare. The most common sites for EGGCTs are in midline locations such as the mediastinum, retroperitoneum and pineal gland. These tumors rarely present in the stomach. We describe here a case where a middle aged man presented with typical symptoms of gastric cancer. After extensive workup, which included blood work, CT abdomen scan, upper endoscopy, and endoscopic ultrasound, the patient was diagnosed with gastric cancer. However, due to very high blood levels of alpha-fetoprotein, the specimen was sent for special histochemical staining, which demonstrated that the tumor had features of both adenocarcinoma and endodermal sinus tumor. This is a very aggressive tumor with a very poor prognosis.
