HPV vaccinations could eliminate cervical cancer, researchers say

The success of the HPV vaccination offers hope of one day eradicating cervical cancer, say scientists who carried out a major review of evidence.

Vaccination against the human papilloma virus, which causes most cervical cancers, began over a decade ago.

A Lancet review of 65 studies covering 60 million people showed a fall in HPV cases and in pre-cancerous growths.

Over decades, this should translate into a significant fall, and possible eradication, of the cancer they said.

The review covered studies in 14 high-income countries, including the UK. They looked at HPV rates, plus cases of genital warts and pre-cancerous cells in the cervix called CIN.

It found that when rates were compared before vaccination started and eight years after:

  • Cases of HPV 16 and 18 were down 83% in girls aged 15-19 – 66% in women 20-24
  • Genital warts cases fell 67% in girls 15-19 – 54% in women 20-24
  • Pre-cancerous growths were down by 51% in girls 15-19 – 31% in women 20-24

It also showed people who were not vaccinated benefited. Cases of genital warts in boys aged 15-19 fell by almost 50%, and also significantly in women over 30.

[Researcher Marc Brisson] said cervical cancer elimination – defined as fewer than four cases per 100,000 – “might be possible if sufficiently high vaccination coverage can be achieved and maintained”.
