Abstract
Purpose
We created a prognostic tool for the prediction of oncologic outcomes after radical nephroureterectomy (RNU) for high-grade non-metastatic upper tract urothelial carcinoma (UTUC).
Methods
UTUC collaboration was utilized to include 586 patients who underwent RNU for non-metastatic high-grade UTUC. Survival outcomes were compared according to a score defined based on the sum of the independent prognostic variables.
Results
The study included 382 males with a median age 70 years (range 28–97). Independent prognostic factors included: T (t stage), A (architecture), LVI (lympho-vascular invasion) and L (lymphadenectomy). TALL score (1–7) was the sum of T (≤T1 = 1, T2 = 2, T3 = 3 and T4 = 4), A (papillary = 0 and sessile = 1), LVI (absent = 0 and present = 1) and L (lymphadenectomy = 0 and no lymphadenectomy = 1). Five-year disease-free survival (DFS) and cancer-specific survival (CSS) were stratified into four risk categories according to the TALL score: low (TALL 0–2; 86 % DFS and 90 % CSS), intermediate (TALL = 3; 71 % DFS and 75 % CSS), high (TALL = 4; 57 % DFS and 58 % CSS) and very high risk (TALL ≥ 5; 34 % DFS and 38 % CSS) using Kaplan–Meier survival analyses. TALL score was externally validated in a single-center cohort of 85 UTUC patients.
Conclusions
We developed a multivariable prognostic tool for the prediction of oncological outcomes after RNU for high-grade UTUC. The score can be used for patient counseling, selection for adjuvant systemic therapies and design of clinical trials.
