Noninvasive papillary serous carcinoma of the endometrium

Objective: To determine the clinical course of noninvasive uterine papillar y serous carcinoma and whether it indicates advanced metastatic disease. Methods: We reviewed the charts of women with noninvasive uterine papillary serous carcinoma who were treated at our institution and abstracted surgic al stage, sites of metastases, disease progression, and length of follow-up . Results: There were 595 cases of endometrial adenocarcinoma between January 1990 and February 2000, 69 of which had papillary serous histology. Sixtee n were noninvasive tumors. Six were confirmed stage IA by complete surgical staging and ten were associated with metastasis at staging. Two of the six women with stage IA tumors had disease recurrence. Conclusions: Noninvasive papillary serous carcinoma is often widely metasta tic. In our experience, approximately two thirds of patients had metastasis , indicating the need for complete surgical staging. Even in those with dis ease limited to the endometrium, a significant percentage will have disease recurrence. (C) 2001 by The American College of Obstetricians and Gynecolo gists.
