PURPOSE: Although already established for very-low and low-risk (LR) prostate cancer (PCa), controversy remains around offering active surveillance (AS) to men with intermediate-risk (IR) PCa. As IR represents a broad spectrum of disease biology, there is a critical need to define eligibility criteria that will enable both patient and physician to accept AS as the best balance of competing risks. In this study, we aimed to identify predictors of progression to enable optimal patient selection...

AIM: In 2012, the International Society of Urological Pathology (ISUP) introduced a novel grading system for clear cell and papillary renal cell carcinoma (RCC) based upon increasing nucleolar prominence in grades 1 to 3, with the presence of extreme nuclear pleomorphism and/or tumour giant cells and/or sarcomatoid and/or rhabdoid differentiation as criteria for grade 4. This system is now incorporated in the latest World Health Organization renal tumour classification, being designated WHO/ISUP grading...

Few studies using the current classification of renal cell carcinoma (RCC) have looked at a large number of cases with near total necrosis. We identified 21 cases of resections of RCC with >90% necrosis from the archives of Johns Hopkins Hospital between 2000-2015. Patients' mean age was 59yrs. (43-77) with 16 (76%) males. 12 (57%) cases were papillary RCC, 4 (19%) clear cell papillary RCC, 4 (19%) clear cell RCC, 1 (5%) unclassified with sarcomatoid differentiation. International Society of Urological Pathology (ISUP) nucleolar grade was grade 1 (9 cases) or grade 2 (9 cases)...

To analyze the presence of mature and immature vessels as a prognostic factor in patients with renal cell carcinoma and propose a classification of renal cancer tumor blood vessels according to morphometric parameters. Tissue samples were obtained from 121 renal cell carcinoma patients who underwent radical nephrectomy. Staining with CD31 and CD34 was used to differentiate between immature (CD31+) and mature (CD34+) blood vessels. We quantified the microvascular density, microvascular area and different morphometric parameters: maximum diameter, minimum diameter, major axis, minor axis, perimeter, radius ratio and roundness...

INTRODUCTION: Mucinous tubular and spindle cell carcinoma (MTSC) of the kidney is a distinct entity characterized by bland tightly packed elongated tubules and spindle cells with low nucleolar grade in a basophilic mucinous stroma. Several case studies have reported MTSC with high grade features and have brought into question whether they represented MTSC or a variant of papillary renal cell carcinoma. MATERIALS AND METHODS: We searched our pathology database and identified seven cases: six MTSC with high International Society of Urological Pathology (ISUP) nucleolar grade, and one MTSC with overall low nucleolar grade but extensive necrosis...

The cranial suture complex is a heterogeneous tissue consisting of osteogenic progenitor cells and mesenchymal stem cells (MSCs) from bone marrow and suture mesenchyme. The fusion of cranial sutures is a highly coordinated and tightly regulated process during development. Craniosynostosis is a congenital malformation caused by premature fusion of cranial sutures. While the progenitor cells derived from the cranial suture complex should prove valuable for studying the molecular mechanisms underlying suture development and pathogenic premature suture fusion, primary human cranial suture progenitors (SuPs) have limited life span and gradually lose osteoblastic ability over passages...

Tumor necrosis has been shown to be an independent predictor of adverse outcome in renal cell carcinoma. A modification of the International Society of Urological Pathology (ISUP) grading system for renal cell carcinomas has recently been proposed, which incorporates the presence of tumor necrosis into grade. The investigators proposing this system found that necrosis added significant prognostic information to ISUP grade. We attempted to describe our experience with the effect of tumor necrosis in relationship to nuclear grade by reviewing the slides from a large consecutive series of localized clear cell renal cell carcinomas from our institution and obtaining long-term clinical follow-up information (overall survival)...

This review focuses on histopathological aspects of carcinoma of the prostate. A tissue diagnosis of adenocarcinoma is often essential for establishing a diagnosis of prostate cancer, and the foundation for a tissue diagnosis is currently light microscopic examination of hematoxylin and eosin (H&E)-stained tissue sections. Markers detected by immunohistochemistry on tissue sections can support a diagnosis of adenocarcinoma that is primary in the prostate gland or metastatic. Histological variants of carcinoma of the prostate are important for diagnostic recognition of cancer or as clinicopathologic entities that have prognostic and/or therapeutic significance...

PURPOSE: The PI-RADS™ (Prostate Imaging Reporting and Data System), version 2 scoring system, introduced in 2015, is based on expert consensus. In the same time frame ISUP (International Society of Urological Pathology) introduced a new pathological scoring system for prostate cancer. Our goal was to prospectively evaluate the cancer detection rates for each PI-RADS, version 2 category and compare them to ISUP group scores in patients undergoing systematic biopsy and magnetic resonance imaging-transrectal ultrasound fusion guided biopsy...

BACKGROUND: Thyroid metastases to distant sites are uncommon incidents, most often metastasizing to the lungs and bones. Rates of metastasis to the kidney are particularly low, ranging from 2.8-3.8% for papillary and 6-20% for follicular variants of well-differentiated thyroid cancers (WDTCs). In rare instances, tumor-to-tumor metastasis between two true primary neoplasms can occurs. This medical phenomenon has previously occurred as a clear cell renal cell carcinoma (CCRCC) spreading to a WDTC...

BACKGROUND: Suppressor of cytokine signaling 1 (SOCS1) is considered a tumor suppressor due to frequent epigenetic and micro-RNA-mediated repression of its gene expression in diverse cancers. In prostate cancer (PCa), elevated expression of miR-30d that targets SOCS1 mRNA is associated with increased risk of disease recurrence. SOCS1 can mediate its tumor suppressor functions by diverse mechanisms such as inhibiting the JAK-STAT signaling pathway, promoting the tumor suppressor functions of p53, attenuating MET receptor tyrosine kinase signaling and blocking the oncogenic potential of the cell cycle inhibitor p21(CIP1) (p21)...

Xp11 translocation renal cell carcinoma (RCC) is a specific type of renal cell carcinoma recently placed under the "MiT family translocation RCC" at the last 2013 ISUP Vancouver classification of renal neoplasia. This tumor contains variable proportions of clear cells and could easily mimic papillary RCC, clear cell type, and clear cell papillary RCC. Given the small number of published cytologic findings of this tumor, it could easily present as a diagnostic pitfall. We describe a case of a 23-year-old man with a history of prior nephrectomy who presented with multiple mediastinal lymphadenopathies on imaging surveillance follow-up...
