There has been a trend for increase in endometrial carcinoma in. Japan in recent years, and many attempts have been made to put endometrial cytodiagnosis into practice in order to detect endometrial carcinoma in the early stage.
In the Department of Gynecology of the Cancer Institute in Tokyo, endometrial cytodiagnosis by the so-called Masubuchi method for endometrial aspiration has been carried out since 1955. The apparatus used for this suction method is a 10ml injection syringe, which can be placed under negative pressure continuously, connected with a polythylene tubing. It is a simple device, its procedure is simple, and the cells can be collected without any pain to the patient. This procedure can be carried out easily on out-patients, in addition to various tests hitherto used for uterine cervical carcinoma.

This Masubuchi method of aspiration cytology and results of endometrial cytodiagnosis in the Department of Gynecology, Cancer Institute Hospital, Tokyo, will be described.
