Chipping away of the yearly exam
Dr. Mutch: With this moving away from the yearly exam and Pap test, women may not get yearly examinations. Do you feel that this could affect a stage migration to a higher stage at diagnosis, for instance, of a cervical cancer? Or that it might adversely impact other health issues?
Dr. Huh: I think that’s a good question. I am worried about the interval—I think 5 years is a bit long. I am more worried that patients will miss out on visits because they may think that they need to only come back for their Pap, even though they should be re-educated on that.
COVID-19 has made this a little hard for us to analyze because, clearly, we have had access to care issues. But I am a little concerned that we could see an uptick in invasive cancer rates in this country, including an uptick in the stage and more locally advanced cervical cancer because of the changes in the screening paradigms. But we don’t know that to be the case.
As with all screenings, the bottom line is you have to worry about what the false-negative and false-positive rates of screening are, and that affects everything. I want the readers to know that primary HPV should be used for screenings. It is not perfect, but it is much better than cytology alone. We need to think about how to better adapt screening in the age that we live in.
HPV self-sampling
Dr. Mutch: Could self-sampling for HPV testing, which obviously would be easier for the patient, and certainly useful in terms of screening, address some health care disparities with regard to cervical cancer?
Dr. Huh: The short answer is, yes. Self-sampling is not US Food and Drug Administration-approved in this country. It’s not being widely used without that approval. But there are multiple countries, including the United States, that have done lots of studies on this topic. There are many public health experts and champions for HPV self-sampling. I think we have learned, based on some studies, that the sensitivity is reasonable.6
I live in a part of the country that is woefully underserved; where you are there are pockets in Missouri that are woefully underserved as well. So the issue is, can we reduce these disparities and access to care with something like self-sampling? My personal feeling is I think that we can make a dent in that, and it is never going to fully replace screening, but it at least will allow us to reallocate our resources and attention to those women that are at highest risk for developing cervical cancer or precancer based on the self-sampling result.
I don’t think it will ever replace screening per se, but if we have an abnormal self-sampling test, we might say to that patient, “You really do need to come in to get re-tested or to get re-evaluated.” So it could be a better resource and use of our health care dollars and investments in terms of trying to reduce the incidence of cervical cancer. Of course the verdict is out, but I think there are a lot of people who would love to see this scenario.
If we screen and treat perfectly in this country, we would not even need the HPV vaccine when it comes to cervical cancer. That is how effective screening is. But, up to 50% to 60% of women in this country now still are underscreened or unscreened. We were talking about that number almost 25-30 years ago, Dr. Mutch. So access to screening is a big problem, but the other problem is how do you get patients in to be seen if they have an abnormal screening test? It’s not just about screening. It’s about screening, evaluation, and treatment; all 3 components are really important.
