1) Purpose and methods:
In recent years, the mass population of screening of uterine cancer by methodof irrigation smears has been carried out in many cities, and considerable results have been obtained.
Setting aside positive cases by this method, however, early cancer may be found in negative cases.
The re-check-up correctly in the level of mass population of screening has been thought as a difficult problem.
The studied about the degree of appearance and quantity of malignant tumor in each cases by method of irrigation smears by patients (a), of smears taken from patients by a gynecologist (doctor) in the some method (b), and the smears in the first examination (c) in 40 cases of Dysplasia and carcinoma in situ by histological examination.
2) Results:
In stage II and more cases of cervical cancer of uterus, the three cases of (a), (b) and (c) are positive. In the irrigation smears taken by a gynecologist, a little better results were obtained than bpatients, however, there is no great difference bey tween them. Carcinoma in situ and Dysplasia are apt to be missed only by the method of irrigation smears. In early cancer, a number of malignant cases are found by cytologic finding at out-clinic and are easy to be diagnosed, while in the method of irrigation smears, there is a small number of cells and more abnormal cells than stage II cases tend to be found.
Comparing the irrigation smears taken correctly by doctors with smears taken by patients, there is no great difference in quantitative relation of malignant tumor.
