Abstract

Adenocarcinoma of the bladder is a rare tumor with incidence in the range between 0.6 and 2.0 % of all epithelial bladder neoplasms. Its prognosis is generally poor compared to transitional cell carcinoma of the bladder. During the past 10 years since 1979, we have experienced 8 cases (3.2%) of adenocarcinoma the bladder among 252 cases of epithelial bladder neoplasms. Six cases of these were primary adenocarcinoma and 2 cases were of urachal origin. Overall two year survival rate was 23% with only 1 case free of cancer up to 3 years. Histologically, the tumors were classified as colonic type (4 cases), clear cell type (1 case), and not otherwise specified type (3 cases), without signet ring cell and colloid type. It might as well be concluded that there is no significant correlation between histologic type and survival rate. However there seems to be a significant correlation between clinical stage and survival rate. Key word : Adenocarcinoma, Bladder tumor.
