Hammad Ather, Nida Zahid
INTRODUCTION: Birt-Hogg-Dubé syndrome (BHDS) is a rare autosomal dominant disease. It is caused by constitutional mutations in the FLCN gene. Since BHDS is a rare syndrome therefore it is unknown to many physicians. However, it is important to identify this rare syndrome at early stages because incidence of renal cancer in BHD patients is very high and its detection at early stages can prevent its metastasis. Hence, we want to present a case of BHDS and draw the attention of the treating physician to this rare inherited disorder and discuss its appropriate diagnosis and management...

Fat embolism is a recognised complication of bony injury and orthopaedic surgery, commonly involving the long bones and pelvis. We report on the case of a 68-year-old renal transplant recipient who developed acute kidney injury following surgical stabilisation of metastatic carcinoma of the acetabulum and replacement of the proximal femur. A CT renal angiogram demonstrated a large fat embolus in the inferior vena cava (IVC) and left iliac veins below the level of IVC filter, with impaired renal perfusion. The risks of open or endovascular lipothrombectomy were felt to outweigh the potential benefits...

OBJECTIVE: Due to lacking external validation, molecular biomarkers are currently not applied for risk-stratification of patients with localized renal cell carcinoma. The objective of this study was to externally validate a molecular multi-marker panel included in a previously proposed prognostic nomogram for the prediction of postoperative disease-free survival. METHODS AND MATERIALS: Besides pathologic tumor stage (pT) and ECOG-Performance Status, the nomogram includes 5 molecular markers (Ki-67, p53, VEGFR-1 endothelial or epithelial, and VEGF-D epithelial)...

Endobronchial ultrasound-guided needle aspiration (EBUS-TBNA) is a well-established procedure with high diagnostic yield and safety. However, the standard 22 gauge needles sometimes cause major bleeding particularly in hypervascular tumors like metastatic lung tumors from renal cell carcinoma (RCC). The 25 gauge needles are already introduced to endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), and are considered as one of the standard devices due to their comparable diagnostic outcome, lower complication risk, and the better manipulability...

We aimed to study the role of METTL3 in renal cell carcinoma (RCC) carcinogenesis and development. Immunohistochemistry was performed in clinical tissue microarray. Expression level of METTL3 in RCC tissues and cell lines was evaluated by quantitative real-time PCR (qRT-PCR) and western blot. Then, the effects of METTL3 on proliferation, migration, invasion and cell cycle were studied in RCC cells. Additionally, in vivo study was carried out in nude mice. Negative METTL3 expression was associated with larger tumor size (P=0...

Multiple therapies currently exist for renal cell carcinoma, however, most do not result in cure and the development of acquired resistance is the rule rather than the exception. CDK4/6 and PIM1 kinases are potential new therapeutic targets in RCC. Abemaciclib is a potent CDK4/6 and PIM1 kinase inhibitor, thus we evaluated the effects of abemaciclib on renal cell carcinoma. In vitro, abemaciclib causes decreased cellular viability, increased apoptosis, and alterations in autophagy in renal cell carcinoma cell lines...

CONTEXT: - Distinguishing chromophobe renal cell carcinoma (chRCC), especially in the presence of eosinophilic cytoplasm, from oncocytoma on hematoxylin-eosin can be difficult and often requires time-consuming ancillary procedures that ultimately may not be informative. OBJECTIVE: - To explore the potential of multiphoton microscopy (MPM) as an alternative and rapid diagnostic tool in differentiating oncocytoma from chRCC at subcellular resolution without tissue processing...

BACKGROUND: Focal renal masses are typically evaluated by means of triphasic contrast-enhanced CT or MRI scan but use of iodinated contrast or gadolinium is unsuitable for some patients. Contrast-enhanced ultrasound (CEUS) is an imaging alternative in this scenario but has limited availability in Ireland. AIM: The aim of the study was to retrospectively evaluate experience with selective use of CEUS for non-invasive characterization of focal renal masses in a tertiary referral institution in Ireland, with a particular focus on cystic renal lesions and the influence of CEUS on final Bosniak classification and treatment outcomes...

Macrophages are the main immune cells of the tumor microenvironment in clear cell renal cell carcinoma (ccRCC). A high density of CD163+ or CD204+ tumor-associated macrophages (TAMs), rather than the density of total TAMs, is known to be linked to poor clinical outcome. In the present study, we investigated the phenotypical differences between the paired primary and metastatic lesions in ccRCC cases. Using immunostaining, the densities of CD163+ and CD204+ TAMs in metastatic lesions were found to be significantly lower compared to primary lesions, although the total number of TAMs was increased in metastatic lesions...

Clear cell renal cell carcinoma (ccRCC) is characterized by stabilization of hypoxia-inducible factor (HIF1), and mutations in von Hippel-Lindau (VHL) gene. Additionally, in about 40% of ccRCC cases the mutation in PBRM1 (POLYBROMO1) gene coding for a non-core subunit of SWI/SNF chromatin remodeling complex was found suggesting potential impairment of this complex function in ccRCC. In this study we assessed the extent to which the core SWI/SNF complex subunit - INI1 (hSNF5/SMARCB1) is affected in ccRCC and whether it has any consequences on the development of this type of cancer...

Solid organ transplant recipients are at high risk of developing malignancies due to the prolonged use of immunosuppressant drugs. Squamous cell carcinoma of skin can occur in these patients even after decades of organ transplant. A 45-year-old male underwent renal transplant for end-stage renal disease 23 years ago and was on immunosuppressive drugs since then. The patient was on regular follow-up. Three years back, he developed squamous cell carcinoma of both forearms and hands, which was treated with radiation therapy using 8 MeV electrons, by parallel opposed fields to a dose of 60 Gy/30 fractions...

Ying-Hua He, Chen Chen, Zheng Shi
Clear cell renal cell carcinoma (ccRCC) accounts for about 3% of tumors in adults as well as 85% of all primary renal carcinoma. And it is the third most predominant urological carcinoma, but it has the maximum mortality rate. Early diagnosis and proper follow-up of ccRCC patients may improve the prognosis of the illness. Thus, it is imperative to understand the new biomarkers of ccRCC and study new method for the modern therapy of this deadly disease. Furthermore, a large number of microRNAs (miRNAs), small non-coding RNAs, have been relevant to tumor type, stage, or survival and miRNAs might be progressed as the markers of diagnosis or prognosis in ccRCC...

Patients with clear cell renal cell carcinoma (ccRCC) are often diagnosed with both von Hippel-Lindau (VHL) mutations and the constitutive activation of hypoxia-inducible factor-dependent signaling. In this study, we investigated the effects of long-term hypoxia in 786-O, a VHL-defective renal cell carcinoma cell line, to identify potential genes and microRNAs associated with tumor malignancy. The transcriptomic profiles of 786-O under normoxia, short-term hypoxia and long-term hypoxia were analyzed using next-generation sequencing...

BACKGROUND: Renal cancer accounts for 3% of adult malignancies; renal cell carcinoma (RCC) represents 80% of all renal cancers, and is characterized by late recurrences. Recurrences after kidney transplantation are associated with a high mortality rate. We aimed to determine if recurrences are linked to tumor characteristics and to delays between diagnosis and transplantation. METHODS: We retrospectively analyzed data from French kidney-transplanted patients with medical histories of pre-transplant renal cancer, focusing on the most common histological subtypes: clear cell and papillary cancers...
