Why vaccinate women ???
• Vaccination before during and after
pregnancy helps protect women from serious
infections .
• It can also help in improving the women’s
health in general .
• It is an important preventable measure which
should be adopted rationally
4. 4
What is Cancer?
• Cancer is the uncontrolled growth of certain
cells in the body, causing tumors or growths.
• Not all growths are cancer.
• Those cells which may spread to other parts of
the body and can interfere with normal
functions are called cancer.

What is Cervical Cancer?
•It is cancer that begins on the
cervix, which is the mouth of
the uterus.

What is Cervical Cancer?
Cells on the cervix begin to grow abnormally and sometimes, if they are not treated, they
become cancer.
However, these early changes can disappear on their own, without causing problems.

What causes Cervical Cancer?
• Cervical cancer is caused by infection with a virus
called human papillomavirus or HPV.
– Approximately 15 to 20 high-risk types are associated
with cancer
– Approximately 10 to 15 low-risk types associated with
genital warts and other benign lesions.
• Most of the time, HPV infection disappears
without treatment; sometimes, however, HPV
stays in the cells for years and, in some women,
eventually causes cervical cancer.

Cervical cancer and HPV infection
• Human papillomavirus (HPV) infection is now a well-
established cause of cervical cancer. HPV causes
virtually 100% of cervical cancer cases
• There is growing evidence of HPV being a relevant
factor in other anogenital cancers (anus, vulva,
vagina and penis) and head and neck cancers.
• HPV is also responsible for other diseases such as
recurrent juvenile respiratory papillomatosis and
genital warts

Cervical cancer and HPV types
• HPV types 16 and 18 are responsible for about 70% of all
cervical cancer cases worldwide. After HPV16/18, the six
most common cervical cancer causing HPV types are 31,
33, 35, 45, 52 and 58
• In India 82.7% of invasive cervical cancers are attributed
to HPVs 16 or 18.
• In India about 5.0% of women in the general population
are estimated to harbor cervical HPV-16/18 infection at a
given time
• HPV types 6 and 11 are responsible for over 90% of all
anogenital warts

How HPV is transmitted?
• Sexually Transmitted
– Genital skin to skin contact
• Non Sexually Transmitted
– Mother to Child
– Fomites
18. 18
Who is at risk of cervical cancer?
• Young age at first sexual intercourse
• Greater number of lifetime and recent sex
partners
• Sex with a new partner
• Male partner sexual history
• In addition to sexual behavior, other potential
risk factors include
– smoking,
– oral contraceptive (OC) use
– nutritional factors
WHO Book - Comprehensive cervical cancer control : a guide to essential practice.
19. 19
What are the signs of cervical cancer?
• Early cervical cancer usually has no signs, which is why
screening is so important.
• Signs of cancer are:
– vaginal spotting or bleeding after sexual intercourse,
between menstruations, or after menopause, and
– foul-smelling discharge that does not go away even
with treatment
WHO Book - Comprehensive cervical cancer control : a guide to essential practice.
20. 20
How is Cervical Cancer diagnosed?
Screening
• It is a test done on people who are healthy and without
symptoms,
– to identify those with a higher chance of getting a particular
disease.
• A cervical cancer screening test can determine if a cervix is
normal or not.
• It can detect early signs of disease before a woman has
symptoms, when treatment can prevent the disease from
developing.
WHO Book - Comprehensive cervical cancer control : a guide to essential practice.
21. 21
What exactly is done during
screening?
• The most common screening test is the Papanicolaou (Pap)
smear.
– Physician will do a genital examination to look at the cervix,
collect a sample of cells from your cervix, and send it to the
laboratory to be examined.
• Other tests are sometimes used to screen for cervical cancer,
– such as looking at the cervix after putting Vinegar/Lugol’s
Iodine on it (VIA or VILI)
WHO Book - Comprehensive cervical cancer control : a guide to essential practice.
23. 23
Can Cervical Cancer be treated?
• Most cervical cancer can be successfully
treated if it is found early.
• In middle aged women who have never been
screened,
– cancer may be discovered late, when it has
already spread beyond the cervix and is more
difficult to treat.

Can Cervical Cancer be prevented?
• Yes, cervical cancer can be prevented by
– Education
– Screening
– Vaccination
28. 28
28
• The definitive cause of cervical cancer is primarily due to high risk HPV infection.
• The disease takes a long time to develop after initial infection.
• Unlike most other types of cancer, it is preventable when precursor lesions are
detected early and treated.
• Therefore, screening can reduce both the incidence and mortality of cervical
cancer.
Preventable?- YES

29. 29
Prevention strategies
Screening:
• Well-organised cervical screening programmes or widespread
good quality cytology can reduce cervical cancer incidence
and mortality.
• However, competing health care priorities, insufficient
financial resources, weak health systems, and limited
numbers of trained providers have made high coverage for
cervical cancer screening in most low- and middle-income
countries difficult to achieve.
Vaccination:
• The introduction of HPV vaccination has considerably
reduced the burden of Cervical cancer.

Why Vaccination?
• HPV vaccines are highly effective at preventing the
infection of susceptible women with the HPV types
covered by the vaccine.
• HPV vaccine should be given to females before they
reach an age when the risk of HPV infection increases
and they are at subsequent risk of cervical cancer.
• HPV vaccine should be ideally given to 10-12 year old
girls as per the IAP recommendation. FOGSI
recommends HPV vaccination at various stages of a
woman's life starting from 9 to 45 years of age
• HPV vaccine is given as 2/3 doses (depending on the
age of recipient) over a period of 6 months.

91. 91
Quadrivalent HPV vaccine
• Offers protection against four HPV types
• Indicated for preventing cervical, vaginal and
vulvar cancers and genital warts
• Can be given to girls as young as 9 years
• Not associated with any serious vaccine
related adverse affects
92. 92
Do these vaccines offer protection against
any non-vaccine HPV types?
Cross-Protection??
93. 93
Cross Protection
• Both the vaccines are supposed to protect against the
infection caused by the HPV types included in them
(QHPV against types 6, 11, 16 & 18 and bHPV against
types 16 & 18).
• Cross protection is when the vaccines offer protection
against any other HPV types which were not included in
the vaccine.
• Both vaccines have shown certain degree of cross
protection against non-vaccine HPV types. But the
clinical significance and longevity of this cross
protection are unclear.

No. 43, 2014, 89, 465–492
94. 94
Potential new vaccines in
development
• To increase the protection conferred by HPV
vaccines, a vaccine has been developed in
which the number of HPV types is increased to
9 by the addition of types 31, 33, 45, 52 and
58 to the quadrivalent vaccine.
• Vaccine based on the HPV L2 viral capsid
protein.

Adolescent vaccination: summary
• Adolescent females may have increased susceptibility
to HPV infection, compared with adults
• Exposure to HPV at a Young Age Increases the Risk of
Cervical Lesions and Cancer
• Studies have shown that early qHPV vaccination is
effective and safe
• Population based/national HPV immunization
programs have shown significant reduction in the HPV
infection and disease burden
• Organization like WHO, FOGSI, API recommend early
HPV vaccination

Cervical Cancer Awareness Level!
• People may not be aware of the tremendous
burden of disease and magnitude of the problem
caused by cervical cancer.
• People may lack accurate information on its
natural history, detection and treatment.
• Many women and men have not heard of cervical
cancer and do not recognize early signs and
symptoms when they occur.
• Women at risk may not be aware of the need to
be tested, even when they do not have any
symptoms.

Key Points
• Cervical cancer is one of the leading causes of
cancer death in Indian women.
• The primary underlying cause of cervical
cancer is infection with human papillomavirus
(HPV), a very common virus.
• Most HPV infections resolve spontaneously;
those that persist may lead to the
development of precancer and cancer.
113. 113
Key Points
• It usually takes 10 to 20 years for lesions caused
by HPV to develop into cancer.
• Over 80% of women newly diagnosed with
cervical cancer live in developing countries; most
are diagnosed when they have advanced disease.
• If left untreated, cervical cancer is almost always
fatal.
• HPV vaccines are highly effective at preventing
the infection of susceptible women with the HPV
types covered by the vaccine
