Routine vaginal Pap test is not useful in women status-post hysterectomy for benign disease

The US Preventive Services Task Force (USPTF) has recommended that routine vaginal Pap (V-Pap) screening is unnecessary for women status-post (S/P) total hysterectomy (T-Hyst) for benign disease (Guide to Clinical Preventive Services. 2nd ed. Baltimore, MD: Williams & Wilkins; 1996. p 105-118). However, many US women continue to have V-Pap despite no risk for cervical cancer and minimal risk for primary vaginal cancer (JAMA 2004;291:2990). Herein, we report our experience with such patients. Computerized data of patients S/P T-Hyst for benign conditions over a 6-yr-period were retrospectively evaluated. Pap diagnoses of epithelial abnormalities (Ep Abnl), negative for intraepithelial lesion or malignancy with/without nonneoplastic findings (NILM-NN and NILM), were reviewed based on three age groups: group A, 18-44 yr; group B, 45-64 yr; and group C, > or =65 yr (JAMA 2004;291:2990). A control group was used.Of 1,860 T-Hyst 1,303 (70%) were for benign disease. Of these 581/1303 (44.5%) patients had 819 current V-Paps (range, 1-5; mean, 1.4). The 581 patients were group A, 288 (49.5%); group B, 272 (46.8%); and group C, 21 (3.6%). Overall, the 819 V-Paps showed Ep Abnl, 28 (3.4%); NILM-NN, 252 (30.7%); and NILM, 539 (65.8%). Of the 28 Ep Abnl, 19 (67.8%) were atypical squamous cells of undetermined significance (ASCUS), and 9 (32%) were low-grade vaginal intraepithelial lesions (LG-VAIN). The NILM-NN findings included organisms, atrophy, and endometriosis. On the basis of individual age groups, Ep Abnl were only seen in V-Paps of 7/288 (2%) of group A and 21/272 (8%) of group B patients. In 23 control patients, 7/71 (9.8%) current V-Paps showed Ep Abnl (ASCUS, 4 (57%); LG-VAIN, 3 (43%)). Continued V-Pap in women S/P T-Hyst for benign disease does not appear to be useful, particularly in those aged > or =65 yr.
