Abstract
— Of the 176 patients treated in our Institute over the last 16 years for upper tract transitional cell carcinoma (UTTCC), 155 were included in this study, 97 of whom had undergone nephroureterectomy, 28 conservative surgery and 30 endourologic treatment. The overall survival rate at 5 and 10 years was 73% and 58%, respectively. Univariate analysis of overall survival rate (O.S.) and disease-free survival rate (D.F.S.) showed no difference between patients with superficial and with invasive tumours, while multivariate analysis highlighted a difference. No difference was evident upon univariate and multivariate analysis of the patients with superficial tumours who underwent conservative (19) vs. radical (45) surgery. The same can be said for the so-called good prognosis tumours (pTa-T1-G2) and poor prognosis tumours (pT1-G3, pT2-4, G2-3) submitted to radical surgery. Overall survival was better in patients with no recurrent tumours compared to those with recurrences; furthermore prognosis was worse for patients with more than 2 recurrences. Tumour site, mono or multifocality and associated bladder tumour did not influence prognosis. Our experience confirms the basic importance of grade as a prognostic factor for UTTCC and the favourable prognosis for patients with superficial tumours, regardless of surgical technique. A rigid follow-up is mandatory for patients with more than 2 recurrences.
