Résumé

Bladder papillomatosis is a diffuse tumor proliferation even up almost all of the bladder mucosa. We analyzed prognosis of this rare entity after conservative treatment. We retrospectively analyzed epidemiological, clinical, therapeutic and evolutive data in 24 patients with newly diagnosed bladder transitional cell carcinoma papillomatosis. All patients underwent a complete endoscopic transurethral resection [TUR] with curative intent. A second look was performed within 30 days. The intravesical therapy regimen consisted on weekly instillations for 6 weeks, and then monthly for 6 months. If the tumor recurred without muscle invasion, TUR was repeated with a second intravesical BCGtherapy regimen. Parameters investigated included age, gender, risk factors, cystoscopic findings [aspect, multiplicity and location of bladder lesion], tumor stage, tumor grade, recurrences and progression times from diagnosis to last follow up. The mean age of the patients at initial diagnosis was 64,9 +/- 6,1 years. They were males in 23 cases. Initial cancer staging was as follow: pTa [n=6] and pT1 [n=18]. The recurring tumors were reported in 17 patients [70,8%]. They were stage Ta in 5 patients and stage T1 in 12. The median interval of time between the initial TUR and the first recurrence was 10,3 months. Six patients remain tumor free. From the 17 recurrences, 6 patients developed progression with muscle invasion in 4 of them. Radical cystectomy with ileal conduit was performed in 3 patients and one patient died before radical treatment. Univariate analysis didn't reveal any prognostic factor: age [p=0,7], tumor location and aspect [p= 0,7 and p= 0,5 respectively], tumor stage [p=0,7] and grade [p=0,09]. TCC bladder papillomatosis is a rare entity. TUR with intravesical BCG therapy may be indicated as a first option despite correct follow up. Radical cystectomy should be considered in cases of recurrent or non-resectable tumours
