[Basic concept in screening for endometrial carcinoma].

A basic concept toward the popularization of screening for endometrial carcinoma was discussed. Cytology obtained from endometrial cavity is mandatory for such a screening method and is more valuable than cytology from the cervix or biopsy obtained by endometrial curettage. When utilized in combination with hysteroscopy, it will be worthwhile for the detection of early endometrial carcinoma with better prognosis. A prospective screening trial was performed on 7,847 women and both high-risk and low-risk factors were evaluated. From these data, the present criteria for starting the screening for endometrial carcinoma are introduced to be as follows; "women who complain of any kind of metrorrhragia" especially, aged 50 or above, postmenopausal, and nulligravida or gravida without pregnancy in recent years. Finally, the future problems of such screening were also discussed.
