Medical Student Research Symposium

Introduction: Upregulation of hypoxia-inducible factors (HIF) is an important pathological feature shared by clear cell renal cell carcinoma (ccRCC) and obstructive sleep apnea (OSA). However, it is unclear whether OSA alters the pathogenesis of ccRCC via HIF expression.

Methods: A retrospective cohort of adults undergoing nephrectomy for ccRCC was identified electronically (IRB#16040-1). The diagnosis of OSA was established with preoperative STOP-BANG scores or polysomnography. A consecutive sample of 20 individuals with and 20 without OSA was selected. Clinical characteristics and pathology results were reviewed. Resected tumor sections were immunohistochemically stained for HIF-1& HIF-2 at antibody dilutions of 1:150. Intensity and …
