Given the remarkably high cure rates for clinical stage (CS) I testicular cancer, the toxicities and risks of adjuvant treatments, the cost effectiveness of surveillance, and the lack of reliable biomarkers to predict relapse, surveillance should be recommended for all patients with CS I testicular cancer.

OBJECTIVE: To examine survival outcomes and molecular drivers in testis cancer among Hispanic men using a large national sample and molecular database. METHODS: We reviewed the SEER registry for testicular cancer from 2000 to 2020. Cox proportional hazards models were used to examine the relationship between race/ethnicity and cancer-specific survival (CSS) by tumor type (seminoma vs. nonseminomatous germ cell tumors [NSGCT]). All models were adjusted for demographic, socioeconomic, and treatment variables...

INTRODUCTION: Paraneoplastic encephalitis (PE) represents a rare but significant complication in patients with testicular cancer (TC). Given the paucity of comprehensive literature on this topic, our review seeks to consolidate current knowledge and provide evidence-based recommendations for the diagnosis, prognosis, and management of PE in the context of TC. MATERIALS AND METHODS: In adherence to PRISMA guidelines, a systematic literature review was conducted from 1950 to April 2024 using PubMed...

Testicular cancer is among the most common solid tumors in young men. Gastrointestinal tract (GIT) metastasis of testicular cancer has been rarely reported. In addition, metastasis occurs most commonly through retroperitoneal lymph nodes. Manifestations like abdominal pain and obstruction can be present if metastasis to GIT was considered. We report here a case of a 34-year-old male who was admitted to our GIT unit complaining of episodic epigastric pain. Computed Tomogram (CT) scan demonstrated a soft tissue like lesion involving the lumen of duodenum...

PURPOSE: Adherence to active surveillance in patients with stage 1 testicular cancers may be influenced by factors affecting capacity and motivation to attend appointments. The aims of this study were to assess adherence to active surveillance and analyze factors which may impact adherence. PATIENTS AND METHODS: A retrospective cohort study was conducted in patients diagnosed with stage 1 testicular cancer between 2005 and 2020, and managed with active surveillance at 3 institutions in South Western Sydney, Australia...

BACKGROUND: The transcription factor SALL4 is associated with embryonic pluripotency and has proposed as a novel immunohistochemistry (IHC) marker for diagnosing germ cell tumors. SALL4 comprises three isoforms, and SALL4-A being the full-length isoform. Studying its isoforms could revolutionize testicular cancer prognosis and subtype differentiation. METHODS: The expression and clinical significance of isoform "A" of SALL4 was evaluated in 124 testicular germ cell tumors (TGCTs) subtypes, adjacent normal tissues and 22 benign tumors, using immunohistochemistry on tissue microarrays (TMA)...

Transverse testicular ectopia (TTE) is an infrequent ectopic testis where both testes descend via the same inguinal canal, located in the same hemiscrotum, and augments the risk of developing testicular tumours. Type II TTE is accompanied by persistent Müllerian duct syndrome, where the Müllerian structures persist for various reasons. Here, we present a case of an adult in his early 30s, who presented with a right testicular swelling and was diagnosed as type II TTE and testicular mixed germ cell tumour after surgery...

OBJECTIVE: Methotrexate (MTX) is widely administered for the treatment of various cancers. However, MTX induces male reproductive toxicity. In the current study, the effect of ozone therapy (OT) on reducing the toxic effects of MTX in the mouse testicles has been investigated. METHODS: Twenty-four mice were divided into four groups: control, OT (4 mg/kg ozone), MTX (20 mg/kg), and MTX + OT. Testosterone levels, histological changes, and oxidative stress biomarkers were assessed to evaluate the protective effects of OT...

Human papillomavirus (HPV), an oncogenic DNA virus, is the most common sexually transmitted virus and significant public health concern globally. Despite the substantial prevalence of HPV infection among men, routine testing remains elusive due to the lack of approved HPV tests and the complexity of detection methods. Various studies have explored the link between HPV and genitourinary cancers, revealing different associations influenced by geographic variation, histological subtype and methodological differences...

Background : Data on the incidence and comorbidity of Lichen sclerosus (LS), based on validated nationwide population-based registries, remains scarce. Objective : To explore the incidence and association of comorbidities with LS in Sweden, emphasizing its potential links to malignancies and autoimmune disorders. Methods : A population-based retrospective open cohort study was conducted using the National Patient Register to identify all individuals diagnosed with LS (ICD-10 code L90.0) from 1 January 2001 to 1 January 2021...

Testicular germ cell tumors (TGCTs) are the most common type of testicular cancer, with a particularly high incidence in the 15-45-year age category. Although highly treatable, resistance to therapy sometimes occurs, with devastating consequences for the patients. Additionally, the young age at diagnosis and the treatment itself pose a great threat to patients' fertility. Despite extensive research concerning genetic and environmental risk factors, little is known about TGCT etiology. However, epigenetics has recently come into the spotlight as a major factor in TGCT initiation, progression, and even resistance to treatment...

Androgen receptor (AR) is a transcription factor expressed in various normal tissues and is a therapeutic target for prostate and possibly other cancers. A TMA containing 18,234 samples from 141 different tumor types/subtypes and 608 samples of 76 different normal tissue types was analyzed by immunohistochemistry. AR positivity was found in 116 tumor types including 66 tumor types (46.8%) with ≥1 strongly positive tumor. Moderate/strong AR positivity was detected in testicular sex cord-stromal tumors (93...

PURPOSE: Ultrasound (US) is the primary imaging modality when a testicular tumor is suspected. Superb microvascular imaging (SMI) is a novel, highly sensitive Doppler technique that allows quantification of flow signals by determination of the Vascular Index (VI). The aim of the present study is to investigate the diagnostic significance of the SMI-derived VI in normal testicular tissue and testicular cancer. METHODS: This retrospective analysis included patients who underwent testicular US in our department from 2018 to 2022...

2-naphthylamine (NAP) was classified as a group I carcinogen associated with bladder cancer. The daily exposure is mostly from cigarette and E-cigarette smoke. NAP can lead to testicular atrophy and interstitial tissue hyperplasia; however, the outcomes of NAP treatment on spermatogenesis and the associated mechanisms have not been reported. The study aimed to investigate the effect of NAP on spermatogenesis and sperm physiologic functions after being persistently exposed to NAP at 5, 20, and 40 mg/kg for 35 days...

Hydrogen sulfide (H2 S), previously regarded as a toxic exhaust and atmospheric pollutant, has emerged as the third gaseous signaling molecule following nitric oxide (NO) and carbon monoxide (CO). Recent research has revealed significant biological effects of H2 S in a variety of systems, such as the nervous, cardiovascular, and digestive systems. Additionally, H2 S has been found to impact reproductive system function and may have therapeutic implications for reproductive disorders. This paper explores the relationship between H2 S and male reproductive disorders, specifically erectile dysfunction, prostate cancer, male infertility, and testicular damage...

Paratesticular rhabdomyosarcoma (PRMS) is a rare and aggressive soft tissue tumour that can mimic testicular sarcoma on initial imaging studies, leading to diagnostic ambiguity and treatment delays. In this case report, we present the case of a 45-year-old male who came to our department and was evaluated under ultrasound imaging along with colour Doppler. The patient underwent further examination under a multi-slice CT machine, which provided additional information, and finally underwent a 1.5T MRI scan. After a provisional diagnosis was made, the patient underwent surgery, and the specimen was sent for histopathology and relevant immunohistopathological markers...

PURPOSE: To apply natural language processing (NLP) to a large volume of structured radiology reports in the investigation of CT imaging features of new liver metastases from primary genitourinary cancers. METHODS: In this retrospective study, a previously reported NLP model was applied to consecutive structured CT reports from 2016 to 2022 to predict those patients with primary genitourinary cancer who developed liver metastasis. Pathology or imaging follow-up served as the reference standard for validating NLP predictions...
