OBJECTIVES: To determine the characteristics of testicular germ cell tumors in older patients. METHODS: A testicular cancer survey was carried out by the Japanese Urological Association in 2011 to register the testicular cancers diagnosed in 2005 and 2008. The survey included age, presenting symptoms, physical examination findings, tumor markers, histopathology, clinical stage, treatment and clinical outcomes. These factors were compared between patients aged ≥50 years and those aged <50 years at diagnosis...

BACKGROUND: The optimal treatment strategy for patients with clinical stage I (CS-1) seminoma is controversial. The objective of the current study was to evaluate the outcomes for patients considered to be at high risk of disease recurrence with a tumor size ≥6 cm. Patients were treated with either adjuvant radiotherapy (RT) or followed with surveillance. METHODS: From the Danish Testicular Cancer database, the authors identified 473 patients with CS-1 seminoma with a tumor size ≥6 cm...

Purpose Adjuvant carboplatin is one of three management strategies that may follow inguinal orchiectomy in clinical stage I seminoma. However, little is known about the outcome of patients who experience a relapse after such treatment. Patients and Methods Data from 185 patients who relapsed after adjuvant carboplatin between January 1987 and August 2013 at 31 centers/groups from 20 countries were collected and retrospectively analyzed. Primary outcomes were disease-free survival and overall survival. Secondary outcomes were time to, stage at, and treatment of relapse as well as rate of subsequent relapses...

Seminomatous germ cell tumours characteristically affect men in their second-to-fourth decades, presenting as a testicular mass. Metastases when present are usually seen in para-aortic lymph nodes. These tumours are difficult to diagnose clinically and histologically when the presentation is unusual. We describe a seminoma presenting in a 61-year-old male as an inguinal mass with associated lymphadenopathy resembling lymphoma. Past medical history included ipsilateral cryptorchidism and orchidopexy. The tumour responded well to conventional chemotherapy...

Testicular germ cell tumours of young adults are comprised of a heterogeneous group of non-seminomas and a homogeneous group of seminomas. While the majority of seminomas retain a hypo-methylated genome, a small fraction displays a highly methylated genome, resembling hyper-methylated non-seminomas. It is well established from e.g. melanoma, colorectal and thyroid cancer that a methylated phenotype can be correlated to prognosis and can be related to BRAF mutations. In the present study we investigated the global methylation level in 67 seminomas and classified them as hypo-methylated, intermediate, patchy and hyper-methylated, respectively...

The birth of a child with a disorder of sex development (DSD) prompts a long-term management strategy that involves a myriad of professionals working with the family. There has been progress in diagnosis, surgical techniques and in understanding psychosocial issues related to this condition. However, since these kinds of disorders are rare and have many anatomical variations, individual care is necessary, especially regarding surgical management. Gonadectomy is indicated in a number of intersex disorders with a Y chromosome to reduce the associated risk of cancer...

BACKGROUND: Nonseminomatous germ cell tumor of the testis (NSGCT) is largely curable. However, a small group of patients develop refractory disease. We investigated the hypothesis that intratumoral heterogeneity contributes to the emergence of chemoresistance and the development of refractory tumor subtypes. RESULTS: Our institution's records for January 2000 through December 2010 included 275 patients whose primary tumor showed pure embryonal carcinoma (pure E); mixed embryonal carcinoma, yolk sac tumor, and teratoma (EYT); or mixed embryonal carcinoma, yolk sac tumor, seminoma, and teratoma (EYST)...

BACKGROUND: Cisplatin-based chemotherapy followed by surgical resection of the residual tumor remains the standard of care for patients with mediastinal germ cell tumors (MGCTs). To prevent pulmonary complications, a non-bleomycin-containing regimen is generally preferred. This study aims to review the clinical characteristics and outcomes of these patients. METHODS: A retrospective chart review was undertaken in patients treated for MGCTs between 2003 and 2013...

A 7-year-old stallion with progressive left testicular enlargement was presented. Grossly, the excised testicle measured 25 × 15 × 12 cm and weighed 3.7 kg. It was multinodular with a gray-white surface; however, the right testis was normal. Histologically, the neoplastic cells were disseminated diffusely in the tumoral stroma with a minimal fibrovascular stroma. Neoplastic cells were round to polygonal with abundant eosinophilic cytoplasm and large round to oval vesicular or hyperchromatic nucleous with a single prominent nucleolus...

OBJECTIVES: To characterize the incidence, presentation, management, and relapse of a large population of bilateral testicular germ cell tumors (TGCT) from a single institution. METHODS: We identified bilateral TGCT diagnosed between 1/1989 and 2/2014. We categorized synchronous and metachronous TGCT, noting time between 1(st) and 2(nd) TGCT, histology [seminoma vs. nonseminoma (NSGCT)], stage and treatments. Kaplan Meier survival estimates characterized relapse...

Testicular germ cell tumors (TGCTs) share germline ancestry but diverge phenotypically and clinically as seminoma (SE) and nonseminoma (NSE), the latter including the pluripotent embryonal carcinoma (EC) and its differentiated derivatives, teratoma (TE), yolk sac tumor (YST), and choriocarcinoma. Epigenomes from TGCTs may illuminate reprogramming in both normal development and testicular tumorigenesis. Herein we investigate pure-histological forms of 130 TGCTs for conserved and subtype-specific DNA methylation, including analysis of relatedness to pluripotent stem cell (ESC, iPSC), primordial germ cell (PGC), and differentiated somatic references...

BACKGROUND: Anticancer treatments can impair male fertility. Cryopreservation of semen is an efficient procedure for fertility preservation. The aim of this study was to evaluate pre-freeze semen parameters among the various types of cancer, post-thaw sperm viability and reproductive outcome of samples used for assisted reproductive treatment (ART). METHODS: This study included 721 men with cancer that had their semen cryopreserved in our bank in 1999-2015. Semen analysis and cryopreservation were performed before the start of antineoplastic treatment, according to the World Health Organization recommendations, European Commission and Italian law...

Disorders of sex development (DSD) represent a spectrum of conditions in which chromosomal, gonadal, or anatomic sex are atypical and affect 1 in 4,500-5,000 live births. The diagnosis of DSD raises concerns of tumor risk and treatment as well as future fertility preservation. We review the current understanding of the types of gonadal tumors that arise in DSD patients as well as possible markers and treatment. The goal is to inform the members of the DSD team (urologist, endocrinologist, geneticist, psychologist) of the latest findings regarding malignancy in DSD...

INTRODUCTION AND OBJECTIVE: Retroperitoneal lymph node dissection (RPLND) is indicated for patients with non-seminoma¬tous germ cell tumor (NSGCT) with residual disease after chemotherapy. Although the gold standard approach is still the open surgery, few cases of robot-assisted laparoscopic RPLND have been described. Herein, we aim to present the surgical technique for robot-assisted laparoscopic RPLND. PATIENT AND METHOD: A 30 year-old asymptomatic man presented with left testicular swelling for 2 months...
