Purpose: To show the importance of complete surgical pathologic staging of clinical Stage I endometrial adenocarcinoma.
Methods: A total of 106 consecutive cases of clinical Stage I endometrial adenocarcinomas in two different centers were studied.
Results: We found an isolated paraaortic invasion in one patient without pelvic node invasion (0.94%). There were only three cases of pelvic lymph-node invasion (2.83%) and three cases of pelvic-paraaortic lymph-node invasion.
Conclusion: We recommend complete lymphadenectom; the real stages of the cases can be determined more correctly and excessive treatments can be avoided.
