Similar but more discerning results have been reported for tumors staged with the TNM classification system, confirming that the extent of locoregional or systemic disease at diagnosis is the primary determinant of outcome for this disease."- Campbell- Walsh Urology 9/e Section XII- Neoplasms of the upper urinary tract, Chapter 47; 8/e p1604
