[The Szontágh IUD and cervix carcinoma (results of a 10-year follow up study)].

Based on a ten-year follow-up of 8334 Szontágh IUD (a non-medicated, Hungarian-made device) cases, the author evaluates the connection between the IUD and the cervical cancer. At the end of the tenth year, the number of those at risk is 1159, and the cumulative woman-month of use is 397 817. During the observation period, 35 devices were removed for suspect colposcopic and/or cytologic findings. Using life table rates the author analyses the occurrence of the invasive and the in situ carcinoma, the dysplasia and those cases where the histopathology performed after the IUD removal resulted in "negative" finding. The 35 removals represent a 5.2 net cumulative termination rate at the end of the 120th month (calculated for 1000 women). The same figure for the 2 in situ and the 3 invasive carcinoma is 0.3 and 0.4, respectively. Evaluating the gross specific (annual) rates, it is stated that there is not any correlation between the duration of the IUD use and the occurrence of cervical malignancy; consequently, the intrauterine contraceptive device does not cause carcinoma. These rates were compared to the overall country figures, and the IUD users showed lower frequency. Of course, it does not mean that the device gives protection against malignancy, but it proves that the regular follow-up helps to discover the suspect cases in time.
