Intratumoral heterogeneity (ITH) is a prominent feature of kidney cancer. It is not known whether it has utility in finding associations between protein expression and clinical parameters. We used ITH that is detected by immunohistochemistry (IHC) to aid the association analysis between the loss of SWI/SNF components and clinical parameters.160 ccRCC tumors (40 per tumor stage) were used to generate tissue microarray (TMA). Four foci from different regions of each tumor were selected. IHC was performed against PBRM1, ARID1A, SETD2, SMARCA4, and SMARCA2...

Acquired cystic kidney disease (ACKD) is a condition that occurs predominantly in patients with end-stage renal disease (ESRD). In contrast to hereditary cystic kidney disease, ACKD is characterized by the presence of multiple small cysts in bilaterally small kidneys. Limited pediatric data suggest a high incidence (21.6-45.8%) of ACKD in children on dialysis, comparable to that in adults, with an increased frequency associated with a longer duration of dialysis. Recent research has shed light on the pathogenesis of ACKD, such as activation of proto-oncogenes...

Background: Brain metastases are associated with significant morbidity and mortality. Population-level data describing the incidence and prognosis of patients with brain metastases are lacking. The aim of this study was to characterize the incidence and prognosis of patients with brain metastases at diagnosis of systemic malignancy using recently released data from the Surveillance, Epidemiology, and End Results (SEER) program. Methods: We identified 1,302,166 patients diagnosed with non-hematologic malignancies originating outside of the central nervous system between 2010-2013 and described the incidence proportion and survival of patients with brain metastases...

Aberrant expression of microRNAs correlates with the development and progression of human cancers by targeting downstream proteins. MiR-1202 is downregulated in ovarian cancer and clear cell papillary renal cell carcinoma; however, its role in glioma remains unknown. The purpose of this study was to determine the expression and the role of miR-1202 and to elucidate its regulatory mechanism in glioma. We used quantitative real-time polymerase chain reaction to measure miR-1202 expression in both glioma tissues and cell lines...

BACKGROUND: Diffusion weighted magnetic resonance imaging (DWI) provides both functional and anatomical information regarding tumours but can also be used for tumour detection. Today, tumour treatment response in clinical trials is mainly assessed on Computed Tomography (CT) using established criteria. Despite availability of dedicated software, CT still requires significant manual work for selection and measurement in treatment response evaluation of solid tumours. PURPOSE: To compare the maximum diameter of tumour lesions on CT with the corresponding measurements on diffusion weighted images...

Several tyrosine kinase inhibitors targeting the vascular endothelial growth factor receptors and molecules inhibiting the mammalian target of rapamycin are being used for management of metastatic renal cell carcinoma (mRCC); however, there is still a potential for improvement. Immune checkpoint inhibitors like nivolumab and other PD-1/PD-L1 inhibitors provide an alternative approach for patients with mRCC. In this article, the authors review the safety profile and outcomes of phase 1, 2, and 3 clinical trials of nivolumab in mRCC...

The therapeutic options for patients with metastatic renal cell carcinoma (mRCC) have completely changed during the last ten years. With the sequential use of targeted therapies, median overall survival has increased in daily practice and now it is not uncommon to see patients surviving kidney cancer for more than four to five years. Once treatment fails with the first line targeted therapy, head to head comparisons have shown that cabozantinib, nivolumab and the combination of lenvatinib plus everolimus are more effective than everolimus alone and that axitinib is more active than sorafenib...

OBJECTIVES: Approximately 1 % of all malignant solid tumours of the head and neck area are metastases from primary tumours beneath the clavicles. The aim of this study was to analyse the distribution of primary tumours since meta-analyses might have been biased due to the usually extraordinary character of case reports. MATERIALS AND METHODS: All patient files from 1970 to 2012 from the Oral and Maxillofacial Surgery unit at a University Hospital were analysed regarding the existence of metastases to the head and neck area from distant primaries...

A 78-year-old man was treated with laparoscopic partial nephrectomy for a 4 cm tumour in the lower pole of the left kidney. The patient was discharged 2 days postoperatively. Preoperatively there was no sign of metastasis; the pathology indicated complete removal of the tumour, a renal cell carcinoma. 53 days postoperatively the patient had acute onset of rectal bleeding. A colonoscopy revealed necrosis and three clips on the wall of the colon corresponding to where the descending colon passes over the left kidney...

Purpose Hand-foot syndrome is a common dose limiting toxicity of vascular endothelial growth factor receptor tyrosine kinase inhibitors used for treatment of patients with metastatic renal cell carcinoma. The effect of treatment dose reductions, in the context of hand-foot syndrome, on survival outcomes is reported. Methods This was a retrospective case series of patients receiving vascular endothelial growth factor receptor tyrosine kinase inhibitors from 1 January 2004 to 31 October 2013. The main outcomes were progression-free and overall survival in these patients experiencing hand-foot syndrome and undergoing treatment dose reductions...

The small intestine is a very uncommon and peculiar site for metastasis from renal cell carcinoma (RCC). We present a clinical presentation of insidious and unusual development of a jejunal metastasis while having stable disease in a remainder of metastatic sites, in a patient undergoing immunotherapy with nivolumab. Due to the extreme rarity of metastatic renal cell carcinoma to the lumen of the small bowel, it is easy to overlook and misdiagnose symptoms of this pathologic entity, particularly when the remainder of metastatic disease responds well to ongoing therapy...

Horseshoe kidney is the most common renal fusion anomaly found in about 0.15% to 0.25% of the population. Renal cell carcinoma associated with a horseshoe kidney has been described in fewer than 200 cases. Its incidence and prognosis seems to be not different from those of the general population, but surgical management may be challenging due to unique anatomic features of horseshoe kidneys, such as highly variable vasculature. We report a case of a 69-year-old male with an incidental 48-mm solid mass in the left moiety of a horseshoe kidney, successfully treated by retroperitoneoscopic partial nephrectomy...

High grade mucinous urothelial carcinoma is a rare pathological variant. There is still controversy as to its nomenclature and classification. We report the case of a 64 year old female with history of pelvic pain who was incidentally discovered to have a left upper pole renal mass. Left nephroureterectomy was performed and histopathological examination revealed high grade mucinous urothelial carcinoma. Accurate diagnosis of this distinct pathological entity will allow for better understanding of phenotypic behavior and inform best treatment strategies...

Integrative database analysis was performed to identify novel candidate oncogene AHNAK2 overexpressed in clear cell renal cell carcinoma (ccRCC). However, the function of AHNAK2 in cancer cells is currently unknown. In this study, we first confirmed the upregulation of AHNAK2 in ccRCC tissues compared with adjacent normal tissues in 15 pairs of samples. Then we analyzed AHNAK2 expression in a large cohort of ccRCC patient samples (n = 355), and found that up-regulation of AHNAK2 was positively correlated with tumor progression and poor survival (p = 0...

Long noncoding RNA (lncRNA) has been proven to be involved in many biological processes in ovarian cancer (OC). However, the mechanism still remains unknown. In this study, we screened significantly downregulated NBAT-1, which has been proven to play a significant role in breast cancer, clear cell renal cell carcinoma, and neuroblastoma, but not in OC, in two independent datasets with relatively more samples (GSE18520 and GSE38666) from Gene Expression Omnibus. We found that lncRNA NBAT-1 was obviously downregulated in OC tissue compared to normal ovarian tissue (P<0...
