  • Title: The contribution of endocervical smears to cervical cancer detection.
    Author: Shingleton HM, Gore H, Austin JM, Littleton HJ, Straugin JM.
    Journal: Acta Cytol; 1975; 19(3):261-4. PubMed ID: 1096515.
    Abstract:
    Data from a Colposcopy Clinic have been presented in which endocervical and cervical smears were evaluated in singly and in combination for accuracy and effectiveness. In patients with marked dysplasia, carcinoma in situ and early invasive cancer, false negative results rarely occurred using either cervical or endocervical smears; more false negatives were encountered in the minimal to moderate dysplasia group of lesions. Endocervical smears were found to be unreliable in determining the distribution of cervical neoplasia when correlated with endocervical curettage specimens. These smears contributed little as supplemental screening procedures for early cervical neoplasia since less procedures for early cervical neoplasia since less than three per cent of lesions would have been missed had only a cervical scrape smear been performed. It should be pointed out, however, that this was a young population in which cervical eversion with exposure of endocervical tissue and the neoplastic lesions was the rule. The accuracy of endocervical aspiration and endocervical swab techniques was similar although there was a much higher proportion of unsatisfactory specimens with the dry cotton swab technique.
