Synopsis: Updated cervical cytology screening guidelines by the American College of Obstetrics and Gynecologists recommend a decreased frequency of pap smears for women younger than age 30.

American College of Obstetrics and Gynecologists (ACOG) recently published updated recommendations on the frequency of cervical cytology screening. The main changes were in women younger than age 30, including the first pap to occur no earlier than age 21 (no longer based on the date of sexual debut) and a pap every 2 years for women age 21-29 years. No changes were made to the frequency of pap testing in women older than age 30 (healthy, immune-intact women with three consecutive negative paps may be screened every 3 years).
November was a busy month for women's health care with big changes in screening practices. If you tend toward the paranoid, you may wonder if this is part of a conspiracy to decrease costs. Let me reassure you that the recent pap recommendations have been in the pipeline for well over a year and the changes aren't actually that drastic (see table). These changes are not as controversial as the mammography recommendations and have the support of the American Society for Colposcopy and Cervical Pathology (ASCCP) and the American Cancer Society.1
There are some general caveats to decreasing the frequency of pap smears for any age group. These recommendations are for "low-risk" women, which means not immunocompromised (i.e., HIV/AIDs, transplant patients), or those with prior exposure to diethylstilbestrol (DES). Additionally, women who have undergone previous treatment for CIN 2, CIN 3, or cervical cancer are at risk for recurrent disease and are advised to have annual screening for at least 20 years.2-4
How do these recommendations translate to the office? Unfortunately, you probably have some women younger than age 21 who are already being followed for dysplasia. Become familiar with the ASCCP's guidelines published in 2006 for management of abnormal cytology and histology in adolescent women.2,5 You can download the clinical algorithms at: www.asccp.org/consensus.shtml. The recommendations vary significantly from the management of adult women with a lot more watchful waiting and a lot fewer excisional procedures.
Educating and reassuring our patients about these new screening guidelines can be challenging and time-consuming. Interestingly, my patients younger than age 30 seem thrilled by the prospect of avoiding a pelvic exam and have been very accepting of the new recommendations, while my patients older than age 30 are still skeptical regarding the triennial pap, even though this recommendation has been around for almost 10 years. In any case, here are my "60-second" counseling points, which hopefully will keep your busy clinic running on time, too:
