Effect of smoking on micronucleated epithelial cells in smears from the uterine cervix.
A pilot study was conducted to determine whether any relationship exists between micronucleated cell rates of female uterine cervical epithelium and current smoking status. Cervical uterine cells obtained from 118 pre-menopausal females, seen between September 1994 and June 1995 at the Occupational Medecine Interprofessional Association (AIMT), were tested for micronucleated cells by the micronucleus assay. Of the 68 subjects taken from this population that provided a least a 1000 analysed cells, 36 were non-smokers and 32 were smokers. Age distributions were different between smokers and non-smokers but results showed that age had no effect on micronucleated cell levels. Micronucleated cervical cell rates reached 0.66% in non-smokers and 1.11% in smokers: these two levels were not statistically different. No association was noted between number of cigarettes smoked and micronucleated cell levels. Results suggested that consuming 5-20 cigarettes per day was not enough to show a smoking effect on cervical micronucleated cells. A test with a greater number of female subjects would be necessary to confirm this.
