[Phenotypic changes in mucin-secreting cells in the ileal neobladder mucosa: a metaplastic or precancerous lesion?].
Colonic metaplasia with shifting from sialo-to sulfomucins was observed in 10/18 patients with ileal orthotopic neobladder; their median follow-up was 59 months. There is a significant statistical relationship (p = 0.002) between Colonic Metaplasia and a follow-up longer than 14 months. Diversion Cancer is nowadays a practical problem and probably urologists will be confronted with it in the future more than at present. A modification of established attitudes as regards urinary diversion in standard situations (i.e., 60 over years old patients with invasive bladder cancer) don't seems, at present, justified, although our study confirms the suspicion that ileal neobladder could be considered theoretically at risk for cancer onset.
