USPSTF Updates Recommendations on Cervical Cancer Screening

The US Preventive Services Task Force (USPSTF) has posted a draft updated statement on cervical cancer screening. The statement is open for public comment until January 13, 2025, on the task force’s website. 

Nearly all cases of cervical cancer are caused by human papilloma virus (HPV) and most occur in women who have not been regularly screened or appropriately treated, the task force stressed.

New Screening Option

In 2024, there will be an estimated 13,820 new cases of cervical cancer and 4360 deaths.

“Evidence shows that screening saves lives, and all women aged 21-65 need to be screened,” said task force member Esa Davis, MD, MPH, FAAFP, a professor of family and community medicine and associate vice president for community health at the University of Maryland, Baltimore, in an interview. A new feature in the 2024 draft statement endorsing self-collection of cervical samples for HPV testing may facilitate broader screening. 

“We hope the new effective option of self-collecting will expand screening and allow even more women to get screened regularly,” Davis said. “Some may feel more comfortable collecting samples themselves, and the collection can be office-based or home-based, but it’s very important that it be done under the direction of a clinician.” 

In agreement is Diego Aviles, MD, an assistant professor and a gynecologic oncologist with UTHealth Houston, Houston. “Self-collection will absolutely expand screening. I think it’s an incredible advancement in medicine that patients are able to collect in the comfort of their own homes with no need to come into the office for an uncomfortable pelvic exam,” he said in an interview. “This empowers the patient and gives her a choice.”

As to concern about potential error, he added that while this is a concern on paper, “a lot of studies have shown that self-collection is just as effective doctor collection.” 

Largely consistent with the task force’s 2018 screening recommendations, the updated suggestions also align with those of other organizations such as the American College of Obstetricians and Gynecologists (ACOG), Davis said.

Christopher M. Zahn, MD, ACOG’s chief of clinical practice and health equity and quality, stressed the importance of cervical cancer screening and said his organization will be reviewing the USPSTF recommendations. He urges ACOG members to consider them and offer their comments on the public-input platform.

Drawing on the latest evidence, the task force is also highlighting for the first time that stand-alone HPV screening gives women aged 30-65 years the best balance of benefits and harms when it comes to finding and preventing cervical cancer, while continuing to reinforce that Pap testing and co-testing are also effective screening options for these women. 

The current draft statement applies to cisgender women and those assigned female sex at birth, including transgender men and nonbinary individuals. The recommendations do not apply to women at increased risk of cervical cancer such as those with HIV infection, a compromised immune system, or a history of treatment for precancerous lesions or cervical cancer. 

Based on a review of evidence on the benefits and harms of screening, the USPSTF’s independent panel of national experts proposed the following: 
 

Recommendations for screening (based on Grade-A evidence):

• Ages 21-65 years: All women should get screened regularly for this preventable disease.
• Ages 21-29 years: All women in this age group should undergo a Pap test every 3 years but do not need HPV testing. “In this age group most HPV infections will go away on their own because young women have strong immune systems. Older women are likely to have HPV that lasts longer and so they need testing for the virus,” Davis said.
• Ages 30-65 years: As noted, HPV screening gives women in this age category the best balance of benefits and harms in terms of preventing and finding cervical cancer. Pap testing or co-testing (Pap tests and HPV tests) are also effective screening options for this population. Ideally, these women should have an HPV test every 5 years or, alternatively, a Pap test every 3 years, or a combined HPV and Pap test every 5 years (co-testing).

Recommendations against screening (no benefit or benefit outweighed by harms – Grade-D evidence):

• Womenaged less than 21 years: Screening is not necessary.
• Other women not needing screening: Nor is screening necessary for those of any age who have had a total hysterectomy with removal of the cervix and those aged > 65 years who have had regular screenings with normal results. That means normal results from their last three Pap tests or their last two HPV tests, completed in the past 10 years, with at least one of the tests done in the past 5 years.
• Women aged 65 or more: These women should continue screening only if they have not been screened regularly or have had abnormal results in the past decade such as a high-grade precancerous lesion (cervical intraepithelial neoplasia grade 2 or 3) or cervical cancer.

Davis noted that none of the current recommendations are likely to be controversial or to spark pushback. “But,” said Aviles, any time I see recent change in medicine, there’s always a little bit of pushback and it may take some time for everyone to be comfortable with the self-collection option. The recommendations still give doctors the grace to use the screening test they feel comfortable with, but I think eventually everyone will get on board with self-collection.”

As for the future, he added, “Over the next few years we’ll have to look at women who are on immune-weakening medications like Skyrizi [risankizumab] for skin conditions like psoriasis. These are commonly used in young people and can increase the risk of cervical cancer. I haven’t seen a lot of conversation about this, but patients should be aware of this risk and recommendations for this group should be different than for the general population.”

The USPSTF also noted a need to assess the magnitude of the incremental benefit and harms of screening and the interval of multiple rounds of HPV-primary screening in HPV-vaccinated cohorts in US populations.
