Abstract

PIP: This study attempted to elucidate the etiology of cervical cancer by examining its association with a number of factors in a relatively unselected group of women. In 1963, a cytologic screening program was undertaken in Washington County, Maryland. The irrigation smear method was used. The final study group of 4341 was 46% of all white women aged 30-45 years enumerated in the census. Of the 4290 satisfactory smears, 46 were positive or suspicious. Subsequent investigation confirmed 31 cases of which 28 were at Stage 0 and 3 were invasive carcinoma of the cervix. Of 15 with suspicious cytologic findings 6 had confirmed findings, all of which were at Stage 0. Women who were never married had no confirmed cases. Currently-married women had lower rates than women whose marriages had been disrupted. Those who were married at age 16 or earlier had higher rates of cervical cancer as did those from lower socioeconomic levels. Having had multiple sex partners was associated with an increased risk of developing cervical cancer. Smokers had slightly higher rates than nonsmokers. Trichomonas vaginali s infestation was associated with higher rates. Findings indicate that trichomoniasis and cervical cancer are both associated with sexual activity.
