Variant histology in upper tract carcinomas: Analysis of the National Cancer Database.

Introduction: Upper urinary tract malignancies are relatively uncommon, with the majority representing urothelial carcinoma (UC). Variant histology (VH) is rare but has been increasingly shown to confer worse prognoses, and standardized approaches to treatment for upper tract cancers with VH have not been established. Our study aimed to analyze outcomes amongst various treatment modalities for upper tract malignancies based on VH subtype.

Robotic surgery for cT2 kidney cancer: analysis of the National Cancer Database.

Robotic surgery for renal cell carcinoma (RCC) is increasingly adopted for cT1 disease, but its utilization for cT2 disease remains unexplored. We aimed to characterize the trend in robotic approach for cT2 RCC. The National Cancer Database was queried for patients who were diagnosed with cT2N0M0 RCC from 2010 to 2016 and underwent subsequent radical (RN) or partial (PN) nephrectomy.
