Neoadjuvant Radiotherapy for High-risk UTUC

The investigators propose to conduct an open-label, single-arm, prospective cohort study to collect and observe high-risk UTUC patients (with clear pathology of urothelial carcinoma and at least one of the following (muscle invasion \[cT2 and above\], high-grade tumour, multifocality, tumour diameter of ≥2cm, with hydronephrosis or regional lymph node metastasis) who undergo neoadjuvant therapy(neoadjuvant radiotherapy with/without drug) + radical nephroureterectomy. The cohort was evaluated by regular follow-up for safety and prognosis during the real-world neoadjuvant treatment period, perioperative period, and long-term postoperative follow-up.
