A study was made of discrepancy between cytologic diagnosis and histologic diagnosis of 64 cases in collective examinations of patients with suspected uterine cancer in Fukushima Prefecture. A few find ings in this study are described hereunder:
1.The average age of the patients was 48.4. of these patients, 73.43% displayed no signs of vaginal or uterine erosion.
2.The average age of patients who are found at the time of surgery to have been affected by intraepithelial cancer was 46.8, while that of patients with early invasive cancer was 50.9, there being a difference of about four years between these two averages.
3. The accuracy of punch biopsy in the cases which had been cytologically diagnosed as Class IV or Vwas 73.91% in the calendar year 1972 and 70.16% in the calendar year 1973.
4. The accuracy in diagnosing cancer by means of cytologic checks was 95.31%.
5. The discrepancy between cytologic diagnosis and histologic diagnosis may be attributed to retro gression of the squamocolumnar junction, i. e., it should be located within the cervix, and also to the minor share of less than 1/4 by ring-shape propagation of foci in the cases of intraepithelial cancer, whereas they were mainly located within the S. C. J.
6.On the basis of the above findings, it is considered mandatory to perform cone biopsy and cone section diagnosis (Sturmdorf's operation) for purposes of deciding which surgical procedures may be required.
