Abstract Ferroptosis is an iron-dependent, excessive lipid peroxidation-driven form of regulated cell death. The core mechanisms of ferroptosis include lipid peroxidation cascade, System X_c⁻-glutathioneglutathione peroxidase 4 axis, iron and lipid metabolism chaos, the NAD(P)Hferroptosis suppressor protein 1—ubiquinone axis, and GTP cyclohydrolase 1 tetrahydrobiopterin-dihydrofolate reductase axis. Cuproptosis is triggered by copper ions and involves ferredoxin 1-mediated aggregation of lipoylated proteins, differing fundamentally from ferroptosis. Both ferroptosis and cuproptosis exhibit dual roles (promote or inhibit) in cancers. And the sensitivity of different cancer types to ferroptosis varies, which may depend on special metabolic signatures (e.g., E-cadherin loss causes epithelial–mesenchymal More > Graphic Abstract

Abstract Objectives: High-grade serous ovarian cancer (HGSOC), the most common subtype of epithelial ovarian cancer (EOC), exhibits a mesenchymal phenotype characterized by fibrotic stroma and poor prognosis. Human epididymis protein 4 (HE4), a key diagnostic biomarker for ovarian cancer, is involved in fibrotic processes in several non-malignant diseases. Given the clinical significance of stromal fibrosis in HGSOC and the potential link between HE4 and fibrosis, this study aimed to investigate the role of HE4 in the formation of stromal fibrosis in HGSOC. Methods: A total of 126 patients with gynecological conditions were included and divided into… More > Graphic Abstract

Abstract Objectives: Chromobox 4 (CBX4), a polycomb protein family member linked to tumor pathogenesis via dysregulation, has an incompletely defined role in gastric cancer (GC). The study aimed to investigate the role and mechanism of CBX4 in GC progression and evaluate its potential as a therapeutic target. Methods: CBX4 expression was assessed in GC tissues vs. adjacent non-cancerous tissues and in GC cell lines vs. normal gastric mucosal epithelial cells. Clinicopathological correlations were analyzed. Functional impacts of CBX4 were determined using knockdown and overexpression models in vitro (cell proliferation, migration, invasion) and in vivo (xenograft tumorigenesis in nude… More >

Abstract Male breast cancer (MBC) is rare, representing 0.5%–1% of all breast cancers, but its incidence is increasing due to improved diagnostics and awareness. MBC typically presents in older men, is human epidermal growth factor receptor 2 (HER2)-negative and estrogen receptor (ER)-positive, and lacks routine screening, leading to delayed diagnosis and advanced disease. Major risk factors include hormonal imbalance, radiation exposure, obesity, alcohol use, and Breast Cancer Gene 1 and 2 (BRCA1/2) mutations. Clinically, it may resemble gynecomastia but usually appears as a unilateral, painless mass or nipple discharge. Advances in imaging and liquid biopsy have More >

Abstract Objective: Triple-negative breast cancer (TNBC) is highly aggressive and lacks an effective targeted therapy. This study aimed to elucidate the functions and possible mechanisms of action of zinc finger miz-type containing 2 (ZMIZ2) and minichromosome maintenance complex component 3 (MCM3) in TNBC progression. Methods: The relationship between ZMIZ2 expression and clinical characteristics of TNBC was investigated. In vitro and in vivo experiments were performed to investigate the role of ZMIZ2 dysregulation in TNBC cell malignant behaviors. The regulatory relationship between ZMIZ2 and MCM3 was also explored. Transcriptome sequencing was performed to elucidate possible mechanisms underlying the ZMIZ2/MCM3… More >

Abstract Objectives: Differentiating benign from malignant testicular lesions is essential to avoid unnecessary surgery and ensure timely intervention. While conventional ultrasound remains the first-line imaging method, elastography and MRI provide additional functional and structural information. This study assesses the diagnostic utility of testicular elastography and magnetic resonance imaging (MRI) in differentiating benign and malignant testicular lesions. Methods: Patients with sonographically detected testicular masses were retrospectively evaluated using elastography, scrotal MRI, and tumor markers. Quantitative and qualitative imaging findings, lesion size, and laboratory values were recorded. Statistical analyses included Fisher’s exact test, logistic regression, Receiver operating characteristic… More >

Abstract Background: Some patients with prostate cancer have elevated gonadotropin levels. It is unknown, however, whether this condition directly influences carcinogenesis in the prostate. It is also unknown whether any specific hormone levels are useful to predict aggressive disease. The potential role of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in prostate physiology is widely discussed. The study aimed to evaluate whether patients with this endocrine pattern have different outcomes following radical prostatectomy. Methods: This was a prospective cohort study of consecutive patients undergoing robot-assisted radical prostatectomy at the Andrology and Urology Department, National Medical Research… More >

Abstract Stereotactic body radiotherapy (SBRT) for prostate cancer is a generally well-tolerated treatment but can rarely lead to complications such as fistula formation. We report a 69-year-old male on maintenance ibrutinib for chronic lymphocytic leukemia who developed a fistula between his bladder and vas deferens in the setting of ascending scrotal infection. Despite his prior history of SBRT, the fistula was successfully treated with minimally invasive measures. A combination of abscess debridement, urinary diversion, and broad-spectrum antibiotics helped to achieve fistula resolution. The unique presentation described herein highlights the importance of early aggressive intervention for source More >

Abstract Background: Many studies have evaluated the performance of fluorescence in situ hybridization (FISH) in detecting urothelial carcinoma, while few of them compared it in detecting bladder cancer (BC) vs. upper tract urothelial carcinoma (UTUC). This study aimed to determine and compare the FISH performance in detecting BC and UTUC. Methods: Data of patients with suspected urothelial carcinoma (UC) who accepted FISH from January 2021 to April 2023 were retrieved. The sensitivity and specificity of FISH in detecting BC and UTUC were determined and compared. Results: A total of 145 BC, 62 UTUC, and 170 non-UC patients were… More >

Abstract Abiraterone acetate (ABTA) was approved by the USFDA in 2011 for treating metastatic castration-resistant prostate cancer (mCRPC). ABTA exhibits poor aqueous solubility, inadequate dissolution, low oral bioavailability (<10%), and significant positive food effects. To overcome these limitations, in the present work, ABTA solid dispersions (SDs) were developed by using hot melt extrusion technology (HME) with various grades of hydroxypropyl methylcellulose HME (HPMC HME 15LV and 100LV) at different extrusion temperatures. HPMC HME demonstrated the ability to prevent drug precipitation for up to 120 min compared to the free drug (10 min), sustaining the supersaturation state… More > Graphic Abstract
