Perioperative systemic therapy, current paradigm and ongoing clinical trials in upper tract urothelial cancer.

Purpose of Review: To provide of comprehensive overview of existing and future paradigms for perioperative systemic therapy in the treatment of upper tract urothelial carcinoma.
Recent Findings: Contemporary treatment paradigms for the management of upper tract urothelial carcinoma focus on use of neoadjuvant cisplatin based chemotherapy for high grade disease primarily based on two small single arm phase II clinical trials. More robust evidence from a phase III randomized clinical trial exists for the use of adjuvant platinum based chemotherapy for invasive disease after radical nephroureterectomy, but there are significant concerns about renal function and platinum eligibility after nephroureterectomy. There are currently ongoing clinical trials for nonplatinum based perioperative systemic therapies including checkpoint inhibitors/immunotherapy as well as antibody-drug conjugates, but currently no recommendation can be made for these approaches.
Summary: Current evidence supports neoadjuvant cisplatin chemotherapy in the setting of high grade disease or concern for significant renal dysfunction after radical nephroureterectomy or platinum based adjuvant chemotherapy in eligible patients with advanced disease after surgery. While there is no established role for nonplatinum based therapies yet, multiple ongoing trials exploring use of immunotherapies and antibody-drug conjugates as monotherapy or combination may provide new therapeutic options in this population.
