Non-neoplastic Pathology in Tumor Nephrectomy Specimens.

Risk factors for kidney cancers and medical kidney diseases are similar; therefore, it is not surprising that up to 25% of renal cell carcinoma patients have chronic kidney disease prior to nephrectomy and a significant number of patients with normal prenephrectomy renal function markers progress to chronic kidney disease over time. Evaluation of non-neoplastic parenchyma in tumor nephrectomy specimens can identify patients at risk for progression to chronic kidney disease, which is a critical step for early intervention and potential improvement of morbidity and mortality rates in this patient population.
