What the trial is, and whether it could suit you
Neoadjuvant chemotherapy treatment can be used for specific UTUC patients, especially for highly staged and/or grade tumors, such as kidneys with potentially decreased renal function after RNU. Neoadjuvant therapy is a series of treatments administered preoperatively for UTUC, mainly chemotherapy, and in recent years, novel therapies of immunotherapy have emerged. Since conventional cisplatin neoadjuvant regimens also require high preoperative renal function, neoadjuvant therapy regimens such as immunotherapy provide more effective and feasible treatments for patients who are intolerant to current cisplatin chemotherapy regimens. The aim of this study was to explore the efficacy and safety of the combination of disitamab vedotin, a human epidermal growth factor receptor-2 (HER-2) targeted ADC, and tislelizumab, a humanised PD-1 ICIs, as neoadjuvant treatment for non-metastatic, high-risk
