Cytologic detection of cervical and endometrial carcinoma with other genital tract involvement.
OBJECTIVE
To investigate the possibility of a correct cytologic diagnosis of cervical and endometrial carcinoma with other genital organ involvement.


METHODS
From uteri removed during hysterectomy due to cervical (33 cases) and endometrial (44 cases) cancer, samples were taken by cytobrush or spatula from the ectocervix, endocervix and endometrium of uteri opened longitudinally. Smears and cytosediments were stained by the Papanicolaou polychrome method. Moreover, acid beta-galactosidase activity was demonstrated in serial cytosediments by the indigogenic method of Lojda. From quenched tissue samples taken from the same sites as those for cytology, a series of cryostat sections was prepared and stained by hematoxylin and eosin or azure A, or subjected to the reaction for acid beta-galactosidase.


RESULTS
In 17 of 33 patients with cervical cancer, the same type of cancer was also found in smears of the endocervix and endometrium. In six patients the type of cancer was different. Of 44 patients with endometrial cancer, 16 had an endocervical malignancy of the same type. In seven cases the type of cancer was different. The reaction for acid beta-galactosidase helped in the differentiation between squamous (negative reaction in cancer cells) and cylindrocellular (positive reaction) cancer in cytologic preparations.


CONCLUSIONS
Before treatment, it is necessary to determine if there is involvement of the endocervix in endometrial cancer and of the endometrium in cervical cancer. Routine cytologic examination supplemented by the reaction for acid beta-galactosidase proved to be useful for this purpose.
