The records of 41 patients diagnosed with adenosarcoma of the female genital tract between 1982 and 1996 were reviewed. The median age at diagnosis is 51 years (range, 14-84). The most common symptom is vaginal bleeding (71%). Clinical signs at presentation include pelvic mass (37%), uterine polyps (29%), and enlarged uterus (22%). In 71% of patients, the tumor originates from the uterus. Other sites include ovary (15%), pelvis (12%), cervix (2%). A history of thyroid cancer, benign ovarian cyst, and polycystic ovarian disease is found more frequently than expected in this patient population, whereas no relationship to endometriosis is observed. Surgery is the mainstay of treatment, but platin-based chemotherapy given upfront in inoperable patient has definite efficacy. An overall response rate of 92.5% was observed after primary therapy (surgery with or without radiotherapy, and/or chemotherapy), with a median survival of 48 months (range, 1-174). Thirty-eight percent of patients had recurrent disease. The median time to recurrence is 12 months (range, 5-132). Although 60% of patients with recurrence achieved a complete remission after treatment, only 1 (8%) is alive without disease, and 3 (22%), with disease at the time of this analysis. In our series, histologic sarcomatous overgrowth is a predictor of poor prognosis (p<0.03), however myometrial invasion and stage of disease seem to be of less prognostic significance. Adenosarcoma is a tumor with a fair prognosis. Most tumor can be cured with surgery, but recurrence carries a bad prognosis.
