Management of upper urinary tract urothelial carcinoma
Bibliographic record
Abstract
Upper urinary tract urothelial carcinoma (UTUC) is relatively uncommon. In this article, we review prognostic factors, criteria and indications for treatment with the available modalities using contemporary data. A systematic search on PubMed was performed using the keywords 'upper tract urothelial carcinoma', 'upper tract transitional cell carcinoma', 'nephroureterectomy', 'laparoscopic', 'endoscopic' and 'prognostic factor'. The literature on UTUC is scarce. No prognostic factors have been formally validated in either the diagnosis or treatment of UTUC. The gold-standard management for invasive UTUC is radical nephroureterectomy with a bladder-cuff excision. Laparoscopic and endoscopic approaches represent alternatives in properly selected individuals. Segmental ureterectomy may also be considered. The extent and role of lymph node dissection remains to be validated. Chemotherapy may also be considered in select patients. Additional multi-institutional studies are needed to identify and validate prognostic factors that can predict the outcomes of patients diagnosed with UTUC. Randomized controlled trials are needed to assess the efficacy of the treatment modalities.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
