title: [Clinicopathological analysis of endometrial carcinoma in young women].
abstract: Endometrial carcinoma in 40 women under 40 years of age (group A), was analyzed clinicopathologically in comparison with that in 126 women over 50 years of age (group B). 1. The incidence of endometrial carcinoma in women under 40 years of age tends to increase. 2. Sixteen (41.0%) of 39 patients in group A had adenoacanthoma, while 28 (23.7%) of 118 patients in group B had it. The tumor in group A was characterized by less myometrial invasion, lower metastatic potential and coexisting endometrial hyperplasia than that in group B. 3. In group A, patients having ovaries with corpus luteum were characterized by less coexisting endometrial hyperplasia and more myometrial invasion than patients having ovaries without corpus luteum.
