[Management of the uterine endometrial cancer cases whose cytological and histologic specimens cannot be obtained from the uterine cavity--assessment by CA125 or vaginal ultrasonography].
An examination for endometrial cancer has been done by cytology. However, cytology is sometimes not possible because of closed or narrow cervix of postmenopausal woman. We did a retrospective study regarding the usefulness of CA125 or transvaginal ultrasonography in postmenopausal cases. The mean +/- S.D. of CA125 in normal menopausal women was 10.3 +/- 3.0 U/ml. The value of mean +/- 2S.D., the finding of Relative Operating Characteristic curve and the purpose that false positive was 0%, so we set 17 U/ml as the cut off value for CA125. In 46 cases with postmenopausal endometrial carcinoma, 23 cases were screened; and in 30 cases with surgical stage I, 10 cases were screened with this cut off value. The echoic patterns for uterine cavities which were observed by transvaginal ultrasonography were divided into 4 patterns (type I: anechoic pattern, type II: linear pattern, type III: clear mass pattern, type IV: unclear mass pattern). In 20 cases with postmenopausal endometrial cancer, 19 cases had type III or IV. In 41 normal postmenopausal women, 26 cases showed an anechoic pattern and 14 cases showed a linear pattern. It was found that 97.5% of cases with anechoic or linear patterns were normal endometrium. The screening by transvaginal ultrasonography was more useful than CA125. However CA125 was more useful than transvaginal ultrasonography in detecting lymph node metastasis.
