Diagnosis of endometrial carcinoma and its precursors by means of cytologic examination of jet-washing material.

Experience with cytologic examination of 138 consecutive jet washings showed the value of the technique as a method of screening for endometrial carcinoma in symptomatic and at-risk patients. In the 127 adequate specimens obtained (92%), all 16 endometrial carcinomas were diagnosed cytologically. The necessity of physician experience in sampling as well as good cytopreparatory techniques in the use of jet washings is emphasized. A dual preparatory routine, including the use of Millipore filter preparations to evaluate cellularity and the type of clusters and the use of smears on chilled slides to evaluate cellular details, was found to be optimal.
