Cervical cancer is a major health problem, but HPV vaccination and screening can reduce rates. HPV is transmitted sexually and can cause cervical cancer. The vaccine protects against high-risk HPV types 16 and 18, which cause most cancers. Northern Ireland has high HPV vaccination rates. While the vaccine reduces cancer risk, screening is still needed since the vaccine does not protect against all HPV types and cannot help women already infected. In the future, screening may shift to HPV testing as prevalence decreases due to vaccination.

Cervical cancer is caused by sexually acquired infections with certain types of HPV. Two HPV types (16 and 18) cause 70% of cervical cancers and pre-cancerous cervical lesions. There is also evidence linking HPV with cancers of the anus, vulva, vagina, penis, and oropharynx

HPV Vaccine: A Breakthrough In Prevention of Cervical CancerApollo Hospitals
Cervical cancer is one of the commonest cancers in women. As it affects young women it has grave
personal, social and economic consequences. It is unfortunate that despite cancer cervix being a preventable
disease, we have failed to reduce the number of deaths related to it. Recent developments in the understanding of the disease process and its link to the oncogenic strains of Human Papilloma Virus (HPV) has opened new avenues in
the way of prevention of cervical cancer.

2. Learning objectives
Define high- and low-risk HPV genotypes
Describe the prevalence of HPV positivity
in Northern Ireland
Discuss the implications of the HPV
vaccination on cervical cancer screening
3. What is HPV
Human papillomavirus is a double-stranded DNA virus that infects
the epithelial cells of skin and mucosa.
The epithelial surfaces include all areas covered by skin and/or
mucosa such as the cervix, vagina, penis, anus, mouth, throat,
tongue, and tonsils.
Referred to papillomavirus as certain types may cause benign skin
warts, or papillomas.
4. High and low-risk HPV subtypes
More than 100 different human papillomavirus (HPV) genotypes have been
identified.
HPV genotypes can be categorized into 2 types depending on oncogenic
potential
“Low-risk” HPVs account for the majority of genital warts; “high-risk” HPVs
refer to those associated with certain types of cancer.
Disease HPV type High/ Low Risk
Anogenital warts 6, 11, 42, 44 and others Low-risk
Genital cancers
16, 18, 45, 31, 33, 52, 58, 35, 59,
56, 39, 51, 73, 68 and 66.
High risk
Head and neck cancer 16, 18 and others High risk
5. Transmission and Activity of HPV
Virus spread by skin contact – mainly by sexual activity.
Many HPV infections are transient.
The virus can remain inactive for a long period after the infection.
Usually the body's immune system responds and clears the HPV
infection.
Persistent HPV infections, pre-malignant conditions and cervical
cancer.

7. How does HPV infection lead to malignancy ?
1. Inactivation of the cellular p53 gene by the E6 oncoprotein
2. Inactivation of the pRB gene by the HPV E7 oncoprotein.
8. Cervical Cancer
Cervical cancer is the second most common cancer in
females after breast cancer.
Globally every year 470,000 new cases are diagnosed,
and 230,000 deaths occur, 80% are in low resource
countries
In Northern Ireland: Each year approximately 80 cases of
cervical cancer are diagnosed; and an average of 30
deaths due to cervical cancer.
5-year relative survival rates are 67.8%.
(Northern Ireland Cancer Registry data)
9. Cervical Cancer
Predominately affects younger women (half of cases aged
44 years or younger).
Large numbers of premalignant Lesions:
Annually an average 700 CIN III lesions, 650 moderate to
severe dysplasia (CIN II) lesions and 170 mild dysplasia
(CIN I) are diagnosed. (Northern Ireland Cancer Registry)
Even after successful treatment of CIN lesions and cervical
cancer, infertility, physical morbidity and psychological
effects can occur.
10. HPV Testing
Testing for HPV is generally not available on request through the NHS.
If a cervical smear test shows signs of borderline changes or mild
dyskaryosis then HPV testing will be carried out.
Identifies whether there is a HPV infection (HPV positive/ HPV
negative) and the genotype of the HPV (high/ low risk) .
Helps determine whether a woman requires treatment and what follow-
up is necessary. (www.nhs.uk)

13. The HPV Vaccine
Two prophylactic vaccines have been developed
Gardasil (Merck) - A quadrivalent vaccine protecting against four
types of HPV – 16,18, 6 and 11.
Cervarix (GlaxoSmithKline) - A bivalent vaccine and protects
against two HPV types - 16 and 18.
Both vaccines require 3 doses over a 6 month period for maximum
effectiveness.
Do not provide protection if already infected with HPV.
14. The HPV Vaccine
Highly effective in preventing infection with the types
of HPV they target.
Avert 70% or more of SCCs by preventing some HPV
infections.
Vaccines duration of protection is uncertain – booster
vaccinations may be needed.
15. The HPV Vaccination Programme (N.I.)
Programme launched on 3 September 2008.
Aimed at girls within year 9 (aged 12 -13)
Cervarix vaccine
Figures from January 2009 – showed a high uptake of
vaccine (89.56% for the first dose and 84.28% for the second
dose).
Catch up programme introduced to include girls aged 13 -18
16. HPV Vaccine And Cervical Screening
Effects of the HPV vaccination programme will take decades
before a noticeable effect on cervical cancer incidence can be
observed.
Long lasting impact on the prevalence of cervical cancer.
The vaccine should:
1. Reduce the need and hence cost for medical care, biopsies, and
invasive procedures associated with the follow- up of abnormal
smear tests.
2. Alleviate the associated anxieties of these procedures.
17. HPV Vaccine And Cervical Screening
Cervical cancer screening will still be required to detect:
1. Cancers and precancerous lesions caused by other
HPV types ~ 30% of cervical cancers.
2. The development of cancers in women who have not
been vaccinated or who are already infected with HPV.
18. HPV Vaccine And Cervical Screening -
Future Considerations
Impact of vaccination on the effectiveness of screening for cervical
cancer.
1. As the prevalence of cervical dysplasias decreases, the positive
predictive value of smear tests (i.e. the likelihood that a positive
screening test will give a correct result ) will decrease. Leading to more
women being referred for unnecessary diagnostic procedures and follow-
up.
2. Maintaining cytology as the primary cervical screening test may become
too costly
Possible introduction of HPV testing as a population screening tool
