Oncocytoma

Glycosaminoglycans (GAGs) were significantly altered in localized as well advanced RCC compared to healthy samples. In addition, GAG scores correlated with progression-free survival and overall survival (OS) in a prospective cohort of patients with metastatic ccRCC and localized RCC. However, it is still unknown whether alterations in plasma and urine GAGs are exquisitely specific to RCC or are shared by other benign lesions in the kidney, such as angiomyolipomas, oncocytomas, or PEComa.

The aim of the present study is the identification, in liquid biopsies, of a new molecular panel able to discriminate renal cancer patients from controls, to discriminate patients with a malignant lesion from those with a benign mass, to determine aggressiveness of RCC, and to differentiate the most common histological subtypes of RCC (clear cell, papillary 1, papillary 2, and chromophobe). This new molecular panel will be combined with clinical parameters to provide a screening test and to improve the accuracy and specificity of diagnosis, prognosis, and histological classification of renal cancer.
