Abstract
To investigate the role of vaginocervical smears in alleged victims of rape, we reviewed the findings in 4,220 consecutive rape victims between the years 1982 and 1989. These rape victims showed a slight increase in cellular abnormalities (1.18% vs .93%) when compared to a group of 17,187 routine smears from an indigent population in 1989. While the differences in the spectrum of cellular abnormalities were not statistically significant, the increase in abnormal smears is remarkable because of the younger age distribution and lower risk factors for cervical cancer in this group of rape victims (41% of the victims were never seen at our institution before their evaluation for alleged rape and were most probably of higher socioeconomic status and at lower risk for cervical cancer than the indigent population served at our hospital). This finding may reflect the low incidence of vaginocervical cytology screening among the general population of which rape victims are a random sample. Fifty-seven percent of the rape victims with cellular abnormalities who were also regular patients at our hospital returned for follow-up by appropriate repeat smears or biopsies. This was lower than the 95% general follow-up rate of vaginocervical smear abnormalities among the rest of the population screened at our hospital. We detected spermatozoa in 56% of the smears from victims who were examined within three days of the alleged sexual assault. Cytology adds to the criminal investigation of rape cases as we detected spermatozoa in four of 16 semen-negative cases from a random sample of 53 cases evaluated by the state crime lab.
