Pap smear screening in women 65 and older

Pap smear screening in women 65 years of age and older is controversial. To assess the need to offer screening in this group, we examined Pap results of women 65 and older whose charts were reviewed as part of a cancer screening study in two San Francisco hospitals. Two hundred thirty women (41%) were 65 years of age or older (mean age, 73). Compared with younger women, they were less likely to have had a Pap smear during the past 3 years (61% versus 72%), less likely to have seen a gynecologist (24% versus 34%), and were more likely to have refused Pap screening (11% versus 5%). Of the 140 women who had Paps, five showed atypia (class II). None exhibited dysplasia or carcinoma in situ. Those with atypia were all nonwhite. One had had a hysterectomy; two had a history of previously abnormal Paps. Overall, women with a history of abnormal Paps were far more likely to be screened (91% versus 58%). Those who had had a hysterectomy were significantly less likely to be screened (51% versus 68%). These results showed a low rate of cervical dysplasia/carcinoma in older, low-income women. Although our sample was small, the low rate of abnormals may reflect the relatively high rate of prior screening in this population. Because older women are not likely to see gynecologists, primary care physicians should continue Pap screening in older women (including those with a history of hysterectomy) until a history of repeated, technically adequate, normal Pap smears is documented.
