MALLEN MATEO, E. et al. Stage pT0 cystectomy: A review of our serie. Actas Urol Esp [online]. 2006, vol.30, n.8, pp.763-771. ISSN 0210-4806.

Objectives: To evaluate the data of progression and survival in 43 patients who underwent cystectomy with stage pT0 according to classification TNM-2002. Matherials and methods: between 1988 and 2003 in our center had realized 420 cystectomies, 43 patients (10.2%) had not tumor in the cystectomy specimen. Results: In these 43 cases the initial clinical stage (in the transuretral resection of bladder) was T1 in 10 cases (23,3 %), T2 in 31 cases (72%) and T3 in 2 cases. As far as the degree 24 patients presented G2 (55.8%) and 19 (44.2%) were G3. Median time from the transuretral resection to the cistectomy was of 44 days at a median follow-up of 89.3 months. Progressionfree survival in the 43 patients was of 180,6 months, but during the follow-up it appeared progression in 7 patients, with disease free survival at 36 months (3-126), since the date of the cistectomía. During the follow up, 5 patients died. When we analyzed the cancer-specific survival according to tumor stage, for the T2 with an average cancer-specific survival is of 180 months, decreasing to 35 months considerably for T3. Similar it happens with the degree of differentiation, significantly diminishing as it advances the degree, with an average of cancer-specific survival for the G3 at 122.6 months. In the same way it happens with pathological positive lymph nodes in the radical cistectomy , with a cancer-specific survival of 188 months when it is N0 and of 54 months if the adenopathy was positive (N+). Conclusion: In our experiencie urothelial carcinoma pT0 present a prolonged free period of disease (medium of 180 months). The associated factors of risk to a smaller free period of disease are high degree of differentiation (G3, 116 months), the infiltration of deep layers in the transuretral resection (T3, 32 months) and the ganglionary affectation (pN+ 45 months).
