Efficacy of combined organ-sparing management of invasive upper urinary tract urothelial carcinoma.

Introduction: The study aimed to evaluate the objective response level to neoadjuvant platinum-based chemotherapy and tumour complexity reduction in patients with invasive upper tract urothelial cancer (UTUC), and to estimate the functional and oncological outcomes of the combined organ-sparing approach compared to radical nephroureterectomy.

Material And Methods: This prospective, non-randomised cohort study was conducted by the National Cancer Institute of Ukraine. Patients with invasive UTUC were enrolled between October 2016 and January 2021.
