HPV and throat cancer - NEW

ABOUT THE CONDITION

What is HPV?

Some cancers of the very back of the throat (tonsil, back of the tongue and soft palate) may be caused by the human papillomavirus, known as HPV.

A small piece of tissue, called a biopsy, can be taken from the back of your throat to find out whether your cancer has been caused by the HPV virus.


Throat cancers caused by HPV and the chance of cure.

The most important feature of throat cancers caused by HPV is that they respond differently to treatment, compared to other throat cancers. The chances of successful treatment and cure are higher than with throat cancers not caused by HPV. This tends to be the case no matter how the cancer is treated – by surgery, radiotherapy, chemotherapy, or a combination of treatments.


How does HPV infect the throat?

HPV infection of the mouth and throat area is extremely common. Most of us will have an HPV infection of the mouth or throat area at some point in our lives, usually as young adults. Most people will overcome an oral or throat HPV infection within a year. However, a very small proportion of the population will not get rid of the infection and it will remain. It is in this very small group of people that cancerous changes may develop, sometimes up to 30 years later, as a result of this infection.

It is important to note that there is often a very long gap, sometimes decades, between the initial infection and the development of cancer in those who do not overcome the infection. This means there is no suggestion that a patient who develops this type of throat cancer has been recently unfaithful. The same applies to their partner.


Are partners of patients with HPV cancer at risk of HPV infection and HPV-related cancer?

Long-term partners of patients with HPV cancer of the throat are usually not at an increased risk of acquiring HPV-associated throat infection. Some HPV 16 subtypes can occur within a small area, but this is very rare. It is thought there is a slightly increased risk of cervical cancer in the female partners of patients with HPV throat cancer, but this has not been proven. Female partners of patients with HPV-related cancer are advised to attend routine cervical screening and have regular smears, as recommended by the National Cervical Screening Programme. No other action is needed.


HPV vaccination

Commercial vaccines (such as Gardasil and Cervarix) are available and protect against HPV 16. These vaccines do not work in people who have already been exposed to the virus. They have no benefit for a patient who has already had a cancer caused by the HPV virus and are unlikely to be effective in their partners.

Since September 2008, the NHS has provided free vaccination against HPV viruses that can cause cervical cancer for girls from the age of 12-13 years old. From September 2019, boys at the age of 12-13 years old have been offered the HPV vaccine in the United Kingdom. If you are eligible but missed your vaccine (or it was not yet offered to you as part of the vaccination schedule e.g. boys born after 1 September 2006) it is available for free on the NHS up until your 25th birthday.

Men who have sex with men (MSM) are also eligible to have the vaccine on the NHS in the United Kingdom if they are aged 45 or under.

Trans-women who were assigned male gender at birth can have the vaccine on the NHS in England and on a case-by-case basis in Scotland.

Trans-men who were assigned female gender at birth, who have sex with other men and are aged 45 or under, can have the vaccine on the NHS in England and on a case-by-case basis in Scotland.


QUICK FACTS

  1. More than 100 types of HPV virus can infect the human body.

  2. HPV infection is common, and the body’s immune system will clear the virus in most people.
  3. HPV infections can be dormant for many years before causing problems.
  4. Certain types of viruses can cause warts.
  5. Some can cause cancers (HPV 16 and 18)
  6. HPV throat infections are common in young adults and most of us will clear the infection without symptoms. In the small proportion of patients who do not clear the virus, a cancer of the throat may develop many years later.
  7. Head and Neck cancers caused by HPV have good outcomes
  8. The HPV vaccine is offered to children between 12 & 13 in the UK
