The clinical and morphologic features in 14 cases of urachal adenocarcinoma are reviewed. The disease occurred more frequently in men than in women. Seven patients (50%) remain alive and currently free of disease at periods ranging from fifteen months to ten years (median: 6 years). Neither the histologic appearance nor the differentiation of the tumor appeared to affect prognosis. It is concluded that the criteria previously recommended to establish the diagnosis of this rare malignancy were too restrictive.
回顾了14例脐尿管腺癌的临床和形态学特征。该疾病在男性中比在女性中更常见。7例患者（50%）存活，目前在15个月至10年（中位数：6年）的时间段内无疾病。肿瘤的组织学表现和分化程度似乎均不影响预后。结论是，先前推荐的用于诊断这种罕见恶性肿瘤的标准过于严格。
