Faced with a positive human papillomavirus (HPV) test, patients are quickly overwhelmed by anxiety-inducing questions. It is crucial to provide them with adequate responses to reassure them, emphasized Jean-Louis Mergui, MD, president of the International Federation for Colposcopy, during the press conference of the Congress of the French Society of Colposcopy and Cervico-Vaginal Pathology.
“Do I have cancer? When did I catch this papillomavirus? Is it dangerous for my partner? How do I get rid of it?” “Not everyone is equipped to answer these four questions. However, it is extremely important that healthcare professionals provide correct answers to patients so that they stop worrying,” Dr. Mergui explained.
Papillomavirus and Cancer
One of the first instincts of patients who receive a positive HPV test is to turn to the Internet. There, they read about “high-risk HPV, which is potentially oncogenic,” and become completely panicked, said Dr. Mergui.
However, among women, the probability of having a high-grade CIN3 lesion or higher on the cervix when the HPV test is positive is about 7%, according to the ATHENA study. “About 93% of patients do not have a severe lesion on the cervix. That’s why colposcopy is not performed on all patients. They need to be reassured,” said Dr. Mergui. When the papillomavirus persists, there is a risk for a cervical lesion. After 11 years, between 20% and 30% of patients develop a high-grade lesion on the cervix. However, on average, a high-risk HPV is spontaneously eliminated within 1-2 years. “After 14 months, 50% of women will test negative for their papillomavirus,” Dr. Mergui noted.
“High-risk HPV does not mean there is a lesion; it means there is a risk of developing a lesion on the cervix one day. That’s why these patients need to be monitored and explored,” he added.
In practice, when a patient aged between 30 and 65 years has a positive HPV test, cytology is performed to look for lesions. Only in the case of an abnormal smear, ASC-US, is colposcopy recommended. In the absence of a lesion, a control HPV test is conducted 1 year later to monitor virus persistence.
It should be noted that patients who have been treated for a cervical lesion have a five times higher risk of developing invasive cervical, vaginal, or vulvar cancer. Therefore, treated patients must be monitored once every 3 years for life.
Time of Infection
Many patients ask, “When did I catch this papillomavirus?” In response, Dr. Mergui first emphasized that HPV infection is common. “Between ages 15 and 30 years, most of us are infected with a high-risk HPV. When we look at the incidence between ages 15 and 25 years, every year, 20% of all young girls are infected with HPV, including 17% with high-risk HPV. The virus is usually caught within the first 5 years of sexual activity, and typically disappears after about a year,” he explained.
However, the most disturbing scenario for patients is when their last examination was negative, and there is no apparent reason for having caught the virus since then. Suspicion often falls on the partner. Once again, the gynecologist seeks to reassure.
It is possible that the last time screening was conducted, the virus was not sought (HPV test), but rather cervical lesions were sought by smear. However, a normal smear does not mean that the papillomavirus is not present. A negative cytology does not mean a negative HPV test. As we have seen, the virus is not always associated with the presence of a lesion, explained Dr. Mergui.
Also, having had a negative HPV test a few years earlier does not mean that one was not already infected. The HPV test determines the quantity of virus. Therefore, it is possible that the virus was present in small quantities that were without clinical significance (hence, a negative test). However, a few years later, the virus may have multiplied, and the HPV test became positive.
“Sometimes, the virus re-emerges 40, 50 years after infection due to age-related immune decline,” said Dr. Mergui. “So, just because the smear was negative or the HPV test was negative at the last examination does not mean that one was infected between the two.” Moreover, only 15% of couples have the same virus present on the penis or vagina, he pointed out.
