RESUMO
UNLABELLED: Retrospective review of 31 cases of bladder adenocarcinoma. METHODS: All patients diagnosed with adenocarcinoma of the bladder at the second affiliated hospital and commercial worker's hospital in Shanxi between 1985 and 1999 were reviewed. RESULTS: The cohort consisted of 31 patients, 25 with primary bladder adenocarcinoma, and 6 patients with urachal adenocarcinoma. Compared to the patients with primary adenocarcinoma, the urachal group were younger (67 versus 56 years), and more likely to be female (M:F 3:1 versus 1:2), and had a worse survival (45% versus 20% at 3 years). In the primary bladder adenocarcinoma group, the 3-year survival rate was 45% after radical cystectomy, and 33% after partial cystectomy. Local tumor recurrence after partial cystectomy was 25%. CONCLUSION: Urachal adenocarcinoma occurred in a younger age group with a female predominance compared to primary adenocarcinoma. Partial cystectomy was associated with a relatively high rate of local tumor recurrence.
