Interleukin-32 (IL-32) is a novel cytokine involved in inflammation and cancer development. IL-32 gene consists of eight small exons, and IL-32 mRNA has nine alternative spliced isoforms, and was thought to be secreted because it contains an internal signal sequence and lacks a transmembrane region. IL-32 is initially expressed selectively in activated T cells by mitogen and activated NK cells and their expression is strongly augmented by microbes, mitogens, and other cytokines. The IL-32 is induced mainly by pathogens and pro-inflammatory cytokines, but IL-32 is more prominent in immune cells than in non-immune tissues...

Renal cell carcinoma (RCC) is a common tumor of the urinary tract. It is known to have variable presentations due to the extremely vascular nature of the organ. RCC are known to metastasize to lungs, bone, and brain commonly but atypical metastasis to various sites are reported in literature but as very rare pathology. We report a case of a 60-year-old female who presented with multiple inguinal and axillary lymph node enlargements which on excision biopsy showed metastatic RCC. RCC can present with synchronous metastatic deposits in the various organs...

BACKGROUND: The apparent diffusion coefficient (ADC) value is known to be an indicator of tumor activity. The ADC value of high-grade clear-cell renal cell carcinoma (RCC) is significantly lower than that of low-grade clear-cell RCC. PURPOSE: To investigate the utility of ADC values of clear-cell RCC by comparing ADC values between groups with T1a RCC (tumor size ≤ 4 cm) without metastasis and the group with metastasis. MATERIAL AND METHODS: A retrospective review was performed on 51 patients with 51 RCCs who underwent 1...

BACKGROUND: Pancreatic tumors often represent primary neoplasms, however organ involvement with metastatic disease can occur. The use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) to determine the underlying pathology provides guidance of clinical management. METHODS: 25 cases were identified in a retrospective review of our institution's records from 2006 to 2016. Clinical parameters and prognosis are described. RESULTS: Metastatic lesions to the pancreas diagnosed by EUS-FNA accounted for 4...

Over the last few decades, the incidence of renal cell carcinomas (RCCs) has been steadily increasing. This is primarily due to an increase in detection of small renal masses (SRMs) as a result of widespread utilization of abdominal imaging. Interestingly, up to 30% of incidentally discovered SRMs (solid lesions measuring ≤4 cm) are benign, and consequently, the definitive treatment of all SRMs is associated with a considerable risk of overtreatment. To decrease the overtreatment rate, renal tumour biopsy (RTB) has been advocated as a safe alternative to identify the pretreatment histology of these SRMs...

Tumors arising from or secondarily involving the vena cava (VC) are broad-spectrum diseases, ranging from benign to malignant. The benign tumors include myxoma, leiomyomatosis and leiomyoma. The primary malignant tumors of the VC are rare, and of these rare entities, leiomyosarcoma is the most frequently encountered. The direct extension of a tumor arising from an adjacent organ such as hepatocellular carcinoma or renal cell carcinoma is more common than primary malignant tumor in the inferior VC. In this article, the authors review the spectrum of VC pathologic processes and the relevant findings from magnetic resonance imaging, ultrasonography, and computed tomography...

Collecting duct carcinoma (CDC) and related tumors [ie, renal medullary carcinoma (RMC)] are rare types of highly aggressive renal cell carcinomas (RCC) with poor prognosis. Because of the rarity and diagnostic uncertainty of them, their molecular pathology and significance have not yet been fully elucidated. CDC, RMC, fumarate hydratase-deficient RCC (including hereditary leiomyomatosis and RCC-associated RCC HLRCC-RCC), and recently reported anaplastic lymphoma kinase (ALK)-rearrangement RCC have significant morphologic overlaps, but they are separately distinct entities having different molecular pathway and clinical settings...

INTRODUCTION: The objective of this study was to determine the reproducibility in a murine model of renal tumours of various histological strains that could be useful for investigating the response to target drugs. MATERIAL AND METHODS: Development and analysis of the "in vivo" model: tumour xenograft of renal cell carcinomas with Balb/c nude athymic mice. Nontumourous human renal tissue was implanted in the interscapular region of 5 mice, chromophobe renal cell carcinoma was implanted in 5 mice (which, after checking its growth, was prepared for implantation in another 10 mice) and Fuhrman grade 2 clear cell renal cell carcinoma (CCRCC) was implanted in 5 mice (which was also subsequently implanted in 10 mice)...

PURPOSE: Drugs currently approved for neovascular age-related macular degeneration (nAMD) offer anti-VEGF monotherapy only. Platelet-derived growth factor (PDGF) signaling is pivotal to pericyte-induced stabilization of choroidal neovascularizations (CNV), and causes partial anti-VEGF resistance. No combination therapy for VEGF and PDGF has been approved yet. Axitinib is a tyrosine kinase inhibitor interfering with VEGF and PDGF signaling, and has been approved for the treatment of renal cell carcinoma...

It is well known that abnormal DNA methylations occur frequently in kidney cancer. However, it remains unclear exactly which types of DNA methyltransferases (DNMT) contribute to the pathologies of kidney cancers. In order to determine the functions of DNA methyltransferase in kidney tumorigenesis on the molecular level, we examined the mRNA expression levels of DNMT1, DNMT3A, DNMT3B, and DNMT3B variants in renal cell carcinoma tissue. Both mRNA and protein levels of DNMT3B4, a splice variant of DNMT3B, were increased in renal cell carcinoma tissue compared with adjacent control tissues...

PURPOSE: Percutaneous biopsy obtained from a single location is prone to sampling error in large heterogeneous renal masses, leading to nondiagnostic results or failure to detect poor prognostic features. We evaluated the accuracy of percutaneous biopsy for large renal masses using a modified multi-quadrant technique vs. a standard biopsy technique. MATERIALS AND METHODS: Clinical and pathological data for all patients with cT2 or greater renal masses who underwent percutaneous biopsy from 2009 to 2014 were reviewed...

Urologic pathology is evolving rapidly. Emerging trends include the expanded diagnostic utility of biomarkers and molecular testing, as well as adapting to the plethora of technical advances occurring in genitourinary oncology, surgical practice, and imaging. We illustrate those trends by highlighting our approach to the diagnostic workup of a few selected disease entities that pathologists may encounter, including newly recognized subtypes of renal cell carcinoma, pheochromocytoma, and prostate cancer, some of which harbor a distinctive chromosomal translocation, gene loss, or mutation...

OBJECTIVES: To describe the effects of cytoreductive nephrectomy (CN) on the natural course of metastatic renal cell carcinoma (mRCC). CN appears to stabilize metastatic lesions in mRCC in a subgroup of patients and we hypothesize that systemic treatment might be deferred in these patients with stable disease after CN. SUBJECTS AND METHODS: Overall, 45 patients with mRCC who underwent CN and subsequent oncologic follow-up were included in this retrospective, single-center analysis...
