This was a retrospective analysis of 240 patients at The Johns Hopkins Hospital between 2003 and 2017 with UTUC. Patients with biopsy-proven high-grade disease with a visible lesion on cross-sectional imaging were offered neoadjuvant chemotherapy prior to RNU. A control group comprised of a time-matched cohort of patients with biopsy proven, high-grade disease underwent extirpative surgery alone.
Overall, there were 32 patients in the study group and 208 patients in the control group. Baseline demographic data was similar between cohorts. There was a significantly lower incidence of lower pathologic stage in the study group compared to the control group
(P<0.001). The incidence of patients with pT2 disease or higher was significantly lower in patients treated with neoadjuvant chemotherapy (37.5% vs. 59.6%; P=0.02). There was a 46.5% reduction in the incidence of pT3 disease or higher in study group patients without clinically node positive or low-volume metastatic disease (25.9% vs. 48.4%; P=0.04) (See figure below). A 9.4% complete remission rate was observed in patients undergoing neoadjuvant chemotherapy.

The authors concluded that patients with high-risk UTUC treated with neoadjuvant chemotherapy are noted to have lower pathologic stage distribution compared to RNU alone.
