[Malignant and premalignant lesions of the uterine cervix. Cytologic contribution to the diagnosis].
A retrospective investigation covering the period 1980-84 showed that in 552 women the histological diagnosis was invasive or pre-invasive (CIN-III) lesion of the uterine cervix. The role of cervical cytology in the diagnosis was evaluated. Cytological smears had been taken from only 34% of women with invasive lesions as compared with 89% of women with pre-invasive lesions. False negative cytological diagnosis was submitted in 7%. In 38% of the patients the cytological smears brought to light less advanced changes than did the subsequent histological examination. Lack of endocervical cells in the smears gave less reliable material than when endocervical cells were present. The investigation gives grounds for the following recommendations: Women over the age of 45 should take greater advantage of the offer of having cervical smears taken. Women with even mild cytological changes must be controlled particularly if there are no endocervical cells present. Lack of endocervical cells in the smears should be reported. Cytological laboratories should send written reminders if requested repeat-smears or biopsies are not received.
