Abstract

OBJECTIVE:

To investigate the outcomes of patients with upper tract urothelial carcinoma (UTUC) with non-definitive therapy, which currently remains unknown.

PATIENTS AND METHODS:

We used the Surveillance, Epidemiology, and End Results (SEER) database to identify individuals with a localised, histologically confirmed kidney/renal pelvis and ureteric UC. Survival analysis using the Kaplan-Meier method was performed. A competing risk model evaluated the cumulative incidence and predictors of cancer-specific mortality (CSM).

RESULTS:

We identified 633 (7.6%) individuals who did not receive surgery. These individuals were significantly older (median age 81 vs 71 years, P < 0.001) than surgically managed patients. The median overall survival (OS) was significantly shorter compared to the surgical cohort (1.9 vs 7.8 years, P < 0.001). The 3-year disease-specific survival (DSS) for patients without surgery was significantly lower compared to those with surgery, at 73.7% vs 92.4%, respectively (P < 0.001). The 3-year DSS for patients with high-grade tumours was worse when compared to patients with low-grade tumours, at 65.1% vs 82.9%, respectively (P < 0.001). The 3-year cumulative CSM was 26.3%. On multivariable analysis, older age (hazard ratio [HR] 1.05, P < 0.001) and high tumour grade (HR 1.88, P < 0.001) were predictors of worse outcomes.

CONCLUSIONS:

In this population-based cohort, 7.6% of patients with UTUC were managed with a non-definitive approach. The median OS for the untreated cohort was significantly shorter compared to the surgical cohort (1.9 vs 7.8 years, respectively). These data may be helpful in counselling patients who are poor surgical candidates, as non-definitive therapy may provide reasonable oncological outcomes.
