Adenocarcinoma of bladder

Forty-eight patients with adenocarcinoma (21 urachal and 27 non-urachal) of the bladder were treated at the Tata Memorial Hospital between 1976 and 1992. The study group consisted of 32 men and 16 women. The urachal tumours were more common in younger patients (mean age: 49 years) than were non-urachal tumours (mean age: 58 years). The overall 5-year survival in this series was 37%. Stage and grade were powerful predictors of outcome. Patients with nonurachal tumours showed an overall survival rate of 29.9% compared with 45.7% in patients with urachal tumours (P = 0.14). Radical cystectomy was the most common treatment modality in patients with non-urachal tumours and yielded an overall 5-year survival of 35%. Patients with urachal tumours were treated with either partial cystectomy or radical cystectomy. The 5-year survival following partial cystectomy was 56.3% compared with 25.9% following a radical cystectomy and the difference between the two was not statistically significant (P = 0.76).
