Metastatic Renal Cell Carcinoma with Level IV Thrombus: Contemporary Management with Complete Response to Neoadjuvant Targeted Therapy.

Case Rep Urol 2019 14;2019:7102504. Epub 2019 Mar 14.

Department of Urology, University of Miami Miller School of Medicine, Miami, FL, USA.

Renal cell carcinoma, particularly the most common clear cell type, is one of the most aggressive of urological cancers with significant risk of metastatic spread. It also has a propensity for venotropism with a proportion of tumors developing thrombi up to the right atrium. The response with newly adopted targeted therapy has been considered to be in the evolutionary stage with no clear role with respect to debulking or reducing the size of the inferior vena cava (IVC) thrombus.

Androgen receptor regulates ASS1P3/miR-34a-5p/ASS1 signaling to promote renal cell carcinoma cell growth.

Cell Death Dis 2019 Apr 18;10(5):339. Epub 2019 Apr 18.

George Whipple Lab for Cancer Research, Departments of Pathology, Urology, Radiation Oncology and The Wilmot Cancer Institute, University of Rochester Medical Center, Rochester, NY, 14642, USA.

Recent studies have demonstrated that the androgen receptor (AR) could play important roles to promote renal cell carcinoma (RCC) cell proliferation, and other studies have also indicated that suppressing the argininosuccinate synthase 1 (ASS1) could promote proliferation of various tumors. The potential of AR promoting cell proliferation in RCC via altering ASS1, however, remains unclear. Here we found that the expression of ASS1 was lower in RCC tissues than in adjacent normal renal tissues, and a lower ASS1 expression was linked to a worse prognosis in RCC patients. Read More

Role of Virtual Biopsy in the Management of Renal Masses.

AJR Am J Roentgenol 2019 Apr 17:1-10. Epub 2019 Apr 17.

1 Department of Radiology, University of Texas Southwestern Medical Center, 2201 Inwood Rd, Ste 210, Dallas, TX 75225.

Renal masses comprise a heterogeneous group of pathological conditions, including benign and indolent diseases and aggressive malignancies, complicating management. In this article, we explore the emerging role of imaging to provide a comprehensive noninvasive characterization of a renal mass-so-called "virtual biopsy"-and its potential use in the management of patients with renal tumors. Percutaneous renal mass biopsy (RMB) remains a valuable method to provide a presurgical histopathologic diagnosis of renal masses, but it is an invasive procedure and is not always feasible.

The therapeutic options available have expanded and now include immune-checkpoint inhibitors, novel targeted agents and combination strategies, and thus optimal patient selection and treatment sequencing are increasingly pertinent for optimizing clinical outcomes. A better understanding of the underlying biology of the tumour and its microenvironment continues to drive the inception of new diagnostic and therapeutic approaches. Read More

Loss of Results in Growth Inhibition and Enhances Mesenchymal-Epithelial Transition in Kidney Tumor Cells.

Mol Cell Proteomics 2019 Apr 16. Epub 2019 Apr 16.

Tsinghua University, China

BRCA1-associated protein 1 (BAP1) is a member of the ubiquitin C‑terminal hydrolase family of deubiquitinating enzymes and is implicated in transcriptional regulation. The BAP1 gene is mutated in about 10% of patients with clear cell renal cell carcinoma (ccRCC), the most common form of renal cancer, suggesting that BAP1 is a tumor suppressor. However, whether BAP1 influences the progression of ccRCC tumors expressing WT BAP1 is unclear. Read More

Impact of tumor size on cancer specific mortality after local tumor ablation in T1a renal cell carcinoma.

J Endourol 2019 Apr 16. Epub 2019 Apr 16.

University of Montreal Health Center, Cancer Prognostics and Health Outcomes Unit, Montreal, Quebec, Canada.

Introduction Institutional studies suggested that tumor size (TS) might be an independent predictor of recurrence after local tumor ablation (LTA). However, limited data exist to ascertain whether larger TS may also predispose to worse cancer-specific mortality (CSM). Materials and methods Patients treated with LTA for T1a non-metastatic RCC were identified within the SEER database (2004-2015). Read More

MicroRNA-508 is downregulated in clear cell renal cell carcinoma and targets ZEB1 to suppress cell proliferation and invasion.

Exp Ther Med 2019 May 1;17(5):3814-3822. Epub 2019 Mar 1.

Department of Urology, Lanzhou University Second Hospital, Lanzhou, Gansu 730000, P.R. China.

Recent studies have identified several microRNAs (miRNAs/miRs) that are dysregulated in clear cell renal cell carcinoma (ccRCC), and their dysregulation may serve important roles in the occurrence and development of ccRCC. Therefore, understanding the expression pattern and functional roles of miRNAs in ccRCC may facilitate the identification of novel therapeutic targets for the treatment of ccRCC. In the current study, reverse transcription-quantitative polymerase chain reaction was used to determine miR-508 expression levels in ccRCC tissue samples and cell lines. Read More

Percentage grade 4 tumour predicts outcome for clear cell renal cell carcinoma.

Pathology 2019 Apr 12. Epub 2019 Apr 12.

Aquesta Specialised Uropathology, Brisbane, Qld, Australia; University of Queensland School of Medicine, Brisbane, Qld, Australia.

Heterogeneity of tumour grading is common in clear cell renal cell carcinoma (ccRCC). WHO/ISUP grading specifies that RCC should be graded based on the highest grade present in at least one high power field. This does not take into account the proportion of high grade tumour present in a cancer, which may itself influence outcome. Read More

Targeting the PD-1/PD-L1 Pathway in Renal Cell Carcinoma.

Int J Mol Sci 2019 Apr 4;20(7). Epub 2019 Apr 4.

Department of Pathology, University Hospital, 35000 Rennes, France.

Renal cell carcinoma encompass distinct diseases with different pathologic features and distinct molecular pathways. Immune checkpoint inhibitors targeting the programmed death receptor ligand 1 (PD-L1)/programmed death receptor 1 (PD-1) pathway alone or in combination have greatly changed clinical management of metastatic renal cell carcinoma, now competing with antiangiogenic drugs in monotherapy for first-line treatment. However, long-term response rates are low, and biomarkers are needed to predict treatment response. Read More
