A clinicopathologic study of 15 cases of primary adenocarcinoma of the uterine tube occurring over a 12-year period is presented. The mean age of the patients was 54.8 years. Predominant symptoms were abnormal bleeding, abnormal vaginal discharge, and pelvic pain. Abnormal vaginal cytology was noted in two instances (13%). A pelvis mass was detected in two thirds of patients. The neoplasm was bilateral in three instances (20%). Lymph nodes were involved in eight cases (53%), and metastatic spread to the para-aortic nodes was present in five (33%). The most common primary treatment was total abdominal hysterectomy and bilateral salpingo-oophorectomy. Various combinations of adjuvant radiation therapy and chemotherapy were also employed. Six patients (40%) are alive without evidence of recurrent cancer. It is concluded that lymphatic spread, especially to the para-aortic nodes, is a major pattern of disseminaton for adenocarcinoma of the uterine tube. The presence of tumor in capillary-like spaces bears a strong relationship to lymph node metastases, and the para-aortic nodes are a frequent site of involvement even when the disease is apparently limited to the tube.
