Brief summary

This prospective cohort study will investigate whether changes in circulating and urinary exosomal biomarkers (target exosomal miRNA) are associated with response to systemic treatment in patients with advanced renal cell carcinoma. Patients treated with immune checkpoint inhibitors or targeted therapies in the first-line or second-line setting will be included. Exosomal biomarker expression will be analyzed in blood and urine samples collected during the first 16 weeks of treatment. Treatment response will be assessed using standard radiological imaging. The study aims to determine whether changes in exosomal miRNA expression after treatment initiation can serve as predictive biomarkers of objective response in advanced kidney cancer.

Detailed description

This is a prospective observational cohort study conducted at the Institute of Oncology Ljubljana. The study will evaluate the predictive value of circulating and urinary exosomal biomarkers (target exosomal miRNA) for response to systemic therapy in patients with advanced renal cell carcinoma. Patients receiving immune checkpoint inhibitors or targeted therapy in the first-line or second-line treatment setting will be enrolled. The primary objective is to determine whether changes in the expression of selected exosomal miRNA in plasma after initiation of systemic treatment are associated with objective response to therapy. In addition, urinary exosomal miRNA will be evaluated as a potential predictive biomarker. Blood and urine samples will be collected during the first 16 weeks of treatment. Each participant will provide four peripheral blood samples (10 mL each) and two urine samples (50 mL each). Radiological imaging will be performed as part of routine clinical follow-up to assess treatment response. The association between changes in exosomal miRNA expression and treatment outcomes will be analyzed.
