PURPOSE Accurate discrimination of benign oncocytoma and malignant renal cell carcinoma is useful for planning appropriate treatment strategies for patients with renal masses. Classification of renal neoplasms solely based on histopathology can be challenging, especially the distinction between chromophobe renal cell carcinoma and oncocytoma. In this study(More)
471 Background: Image-guided percutaneous needle biopsies are increasingly utilized for the diagnosis of renal tumors. Histologic diagnosis of renal mass subtypes, including malignant clear cell (ccRCC), papillary (pRCC), chromophobe (chrRCC) renal cell carcinoma, and benign oncocytomas (OC) can be challenging due to the low cellularity and damaged(More)
OBJECTIVES To improve the overall accuracy of diagnosis in needle biopsies of renal masses, especially small renal masses (SRMs), using fluorescence in situ hybridization (FISH), and to develop a renal cortical neoplasm classification decision tree based on genomic alterations detected by FISH. PATIENTS AND METHODS Ex vivo fine needle aspiration biopsies(More)
Extensive dysregulation of chromatin-modifying genes in clear cell renal cell carcinoma (ccRCC) has been uncovered through next-generation sequencing. However, a scientific understanding of the cross-talk between epigenetic and genomic aberrations remains limited. Here we identify three ccRCC epigenetic clusters, including a clear cell CpG island methylator(More)
