CERVIX- ANATOMY
The cervix or cervix
uteri (Latin: neck of
Uterus) is the lower part
of the uterus in
the human female
reproductive system.
In a non-pregnant
woman, the cervix is
usually 2 to 3 cm long (1
inch) and roughly
cylindrical in shape.
The narrow,
central cervical
canal runs along its
entire length,connecting
CERVIX- ANATOMY
The opening into the
uterus is called
the internal os, and the
opening into the vagina
is called the external os.
The lower part of the
cervix, known as the
vaginal portion of the
cervix (or ectocervix),
bulges into the top of the
vagina.
The cervix has been
documented
anatomically since at
least the time
of Hippocrates, over
CERVICAL CANCER- DEFINITION
Cancer that forms in tissues of the cervix (the organ connecting the uterus and vagina) is known as cervical cancer.
It is usually a slow-growing cancer that may not have symptoms but can be found with regular Pap tests .
Cervical cancer is almost always caused by human papillomavirus (HPV) infection.

RISK FACTORS OF CERVICAL CANCER
HPV (human papillomavirus) - a sexually transmitted virus. There are more than 130 different types of HPVs, at least 18 of which can cause cervical cancer.
Many sexual partners or becoming sexually active early - cervical cancer-causing HPV types are nearly always transmitted as a result of sexual contact with an infected individual.
Women who have had many sexual partners generally have a higher risk of becoming infected with HPV, which raises their risk of developing cervical cancer.
RISK FACTORS OF CERVICAL CANCER
Smoking - increases the risk of developing many cancers,
including cervical cancer.
A weakened immune system - such as in people
with AIDS, or transplant recipients taking
immunosuppressive medications.
Long-term mental stress - women who experience high
levels of stress over a sustained period may be less able to
fight off HPV.
A study from the American Academy of Pediatrics in 2016
supported this. Principal investigator Dr. Anna-Barbara
Moscicki said: "Women who reported self-destructive
coping strategies, like drinking, smoking cigarettes or
taking drugs when stressed, were more likely to
develop an active HPV infection."
RISK FACTORS OF CERVICAL CANCER
Giving birth at a very young age - women who give birth before the age of 17 are significantly more likely to develop cervical cancer compared with women who have their first baby after the age of 25.
Several pregnancies - women who have had at least three children in separate pregnancies are more likely to develop cervical cancer compared to women who have never had children.
Contraceptive pill - long-term use of some common contraceptive pills slightly raises a woman's risk.
RISK FACTORS OF CERVICAL CANCER
Other sexually transmitted diseases
(STD) - women who become infected
with chlamydia, gonorrhea, or syphilis have a
higher risk of developing cervical cancer.
Socio-economic status - studies in several
countries have revealed that women with low
SES have significantly higher rates of
cervical cancer.
HPV DISEASE SPECTRUM
HPV is a member of the family Papillomaviridae.
They are small, non-enveloped deoxyribonucleic acid (DNA) viruses.
Over 130 serotypes of HPV have been discovered, of which 15–20 are oncogenic.
The lag period between the oncogenic HPV infection and the invasive cervical cancer is 15–20 years.
Based on the association with cervical cancer, genital HPVs are further grouped into high-risk types, probable high-risk types and low-risk types.
HPV DISEASE SPECTRUM
Worldwide, high-risk type HPV-16 and 18 contribute over 70% of all cervical cancer cases (the most prevalent being HPV-16 in at least 50–60% and HPV-18 in at least 10–12%).
Similarly, in Indian women, the most common prevalent genotypes are HPV-16 and 18.
Non-oncogenic HPV serotypes-6 and 11 contribute over 90% of benign genital infections such as genital warts.
Oncogenic HPV serotypes have also been implicated in the causation of anal, vulvar, vaginal, penile and oropharyngeal cancers.
HPV DISEASE SPECTRUM
HPVs infect the basal epithelium and are grouped as cutaneous and mucosal types.
HPV cervical infection results in cervical morphological lesions ranging from normal (cytologically normal women) to development of different stages of high-grade precancerous lesions cervical intraepithelial neoplasia:
Cervical intraepithelial neoplasia (CIN)-1, CIN-2, CIN-3/Carcinoma in-situ) and, subsequently, invasive cervical cancer (ICC)

BURDEN OF CERVICAL CANCER- INDIA
In India, cervical
cancer contributes
to approximately 6–
29% of all cancers
in women.
The ASR is highest
23.07/100,000 in
Mizoram( Aizawl
city) state and the
lowest is
4.91/100,000 in
Dibrugarh district.
BURDEN OF CERVICAL CANCER- INDIA
India has a population of approximately 365.71 million women above 15 years of age, who are at risk of developing cervical cancer.
The current estimates indicate approximately 132,000 new cases diagnosed and 74,000 deaths annually in India, accounting to nearly 1/3rd of the global cervical cancer deaths.
(Reference- WHO/ICO Information Centre on HPV and Cervical Cancer (Available from:http://www.who.int/hpvcentre.)
BURDEN OF CERVICAL CANCER- INDIA
At any given time, about 6.6% of women in the general population are estimated to harbor cervical HPV infection.
HPV serotypes 16 and 18 account for nearly 76.7% of cervical cancer in India.
Warts have been reported in 2–25% of sexually transmitted disease clinic attendees in India; however, there is no data on the burden of anogenital warts in the general community.
BURDEN OF CANCER- BIHAR
Vaishali followed by Bhojpur, Begusarai,
Muzaffarpur and Patna districts have the
highest incidence of cancer in the state.
Mahavir Cancer Sansthan (MCS) has come
out with a new research saying over 50, 000
deaths are caused by cancer every year in
Bihar, while over 80,000 new cancer
patients come up every year in the state.

Mostly asymptomatic.
When present, common symptoms of cervical cancer may include:
Vaginal bleeding: This includes bleeding between periods, after sexual intercourse or post-menopausal bleeding.
Unusual vaginal discharge: A watery, pink or foul-smelling discharge is common.
Pelvic pain: Pain during intercourse or at other times may be a sign of abnormal changes to the cervix.
SIGNS AND SYMPTOMS OF CERVICAL CA
Cervical cancer may spread (metastasize) within the pelvis, to the lymph nodes or elsewhere in the body.
Signs of advanced cervical cancer include:
Weight loss
Fatigue
Back pain
Leg pain or swelling

SCREENING OF CERVICAL CANCER
Cervical screening is the process of
detecting and removing abnormal tissue
or cells in the cervix before cervical
cancer develops.
By aiming to detect and treat
cervical neoplasia early on, cervical
screening aims at secondary
prevention of cervical cancer.
CERVICAL CANCER SCREENING
Cervix is amenable to screening by a number
of methods
1. visual inspection with acetic acid (VIA),
2. magnified VIA (VIAM)
3. visual inspection with Lugol's iodine
(VILI),
4. the Papanicolaou test (also Known as
PAP test),
5. and HPV DNA testing.

PAP TEST
The Pap test is recommended for all women between the ages of 21 and 65 years old.
can be done in a doctor’s office or clinic.
During the Pap test, the doctor will collect a few cells and mucus from the cervix and the area around it.
The cells are then placed on a slide or in a bottle of liquid and sent to a laboratory.
HOW TO PREPARE FOR PAP TEST?
You should not schedule
your Pap test for a time
when you are having your
period.
If you are going to have a
Pap test in the next two
days—
You should not douche
(rinse the vagina with
water or another fluid).
You should not use a
tampon.
You should not have sex.
You should not use a birth
control foam, cream, or
HPV TESTING
The HPV test checks for the virus, not cell changes.
The test can be done at the same time as the Pap test, with the same swab or a second swab.
You won’t notice a difference in your exam if you have both tests.
A Pap test plus an HPV test (called co-testing) is the preferred way to find early cervical cancers or pre-cancers in women 30 and older.

DIAGNOSIS OF CERVICAL CANCER
If the Pap test showed some abnormal
cells, and the HPV test is also positive,
the doctor may suggest 1 or more of the
following diagnostic tests:
Colposcopy
Biopsy
Pelvic examination
X-Ray
DIAGNOSIS OF CERVICAL CANCER
CT Scan ( CAT Scan)
PET/PET-CT Scan
Cystoscopy
MRI
Proctoscopy
Laproscopy
COLPOSCOPY
The colposcope is
not inserted into the
woman’s body and
the examination is
not painful, can be
done in the doctor's
office, and has no
side effects.
It can be done on
pregnant women
also.
BIOPSY
Other tests can suggest that cancer is present, but only a biopsy can make a definite diagnosis.
If the lesion is small, the doctor may remove all of it during the biopsy.
There are several types of biopsies:
TYPE OF BIOPSY- ECC
One common method uses an instrument to
pinch off small pieces of cervical tissue.
endocervical curettage (ECC) has been
done to check an area inside the opening of
the cervix,.
the doctor scrapes a small amount of tissue
from inside the cervical opening.
TYPE OF BIOPSY- LEEP/CONE BIOPSY
A loop electrosurgical excision procedure (LEEP) uses an electrical current passed through a thin wire hook.
The hook removes tissue for examination in the laboratory.
A LEEP may also be used to remove a precancer or an early-stage cancer.
Conization (a cone biopsy) removes a cone-shaped piece of tissue from the cervix.
Conization may be done as treatment to remove a precancer or an early-stage cancer.
DIAGNOSIS OF CERVICAL CANCER
Pelvic examination. The specialist may re-
examine the pelvic area while the patient is
under anesthetic to see if the cancer has
spread to any organs near the cervix,
including the uterus, vagina, bladder, or
rectum.
X-ray.
intravenous urography
DIAGNOSIS OF CERVICAL CANCER
Computed tomography (CT or CAT) scan.
A CT scan can also be used to measure the
tumor’s size.
Sometimes, a special dye called a contrast
medium is given before the scan to provide
better detail on the image.
This dye can be injected into a patient’s vein
or given as a pill to swallow.
DIAGNOSIS OF CERVICAL CANCER
Magnetic resonance imaging (MRI). MRI
can also be used to measure the tumor’s
size.
Positron emission tomography (PET) or
PET-CT scan. A PET scan is usually
combined with a CT scan , called a PET-CT
scan
A PET scan is a way to create pictures of
organs and tissues inside the body.
DIAGNOSIS OF CERVICAL CANCER
Cystoscopy. A cystoscopy is used to
determine whether cancer has spread to the
bladder.
Proctoscopy (also called
sigmoidoscopy). A proctoscopy is used to
see if the cancer has spread to the rectum.
Laparoscopy. A laparoscopy is a procedure
that allows the doctor to see the spread of
cancer within abdominal cavity.

PREVENTION OF CERVICAL CANCER
Majority of the women become infected with HPV at some point in their lives, soon after the onset of sexual activity.
The lifetime risk for genital HPV is 50–80% and genital warts is approximately 5%.
In women who undergo routine screening, the risk of having an abnormal Papanicolou (Pap) smear is 35%, CIN 20% and ICC is <1% approximately.
Both HPV Vaccination ( Primary Prevention) and Screening ( Secondary prevention) is important for prevention of cervical cancer.
WHY VACCINATION IS THE BEST FORM OF
PREVENTION
There is no clear evidence that barrier methods of contraception, most notably use of condoms, confer a protection against HPV infection.
Secondly, except for genital warts, the infection is asymptomatic.
Adherence to routine screening by the susceptible female population through periodic Pap smears even in developed countries has been unsatisfactory.
In developing countries like India, large-scale routine screening is difficult to achieve.
DEVELOPMENT OF HPV VACCINE HISTORY
Recombinant DNA technology is used to express the L1 major capsid protein of HPV in yeasts (Saccharomyces cerevisiae), which self-assemble to form empty shells resembling a virus, called virus-like particles (VLPs).
The VLPs have the same outer L1 protein coat as HPV but contain no genetic material.
The vaccine uses these VLPs as antigens to induce a strong protective immune response.
TYPES OF HPV VACCINE
Two vaccines licensed globally are available in
India; a quadrivalent vaccine (Gardasil™
marketed by Merck) and a bivalent vaccine
(Cervarix™ marketed by Glaxo Smith Kline).
Clinical trials with both vaccines have used
efficacy against CIN-2/3 and
adenocarcinoma in situ (AIS) caused by HPV.
These vaccines do not protect against the
serotype with which infection has already
occurred before vaccination.
GARDASIL
Gardasil™ is a mixture of
L1 proteins of HPV
serotypes 16, 18, 6 and 11
with aluminum-containing
adjuvant.
Clinical trials with three
doses at 0, 2 and 6 months
in more than 16,000
women aged 16–26 years
from five continents,
including Asia, have
shown 100% efficacy .
This vaccine confers
protection against both
cervical cancer and genital
warts.
CERVARIX
Cervarix™ is a mixture of L1
proteins of HPV serotypes
16 and 18 with AS04 as an
adjuvant.
Clinical trials with three
doses at 0, 1 and 6 months
in more than 18,000 women
globally has shown 90%
efficacy against type 16/18-
related CIN-2/3 and AIS .
Follow-up studies in a
subset of participants over
4–5 years showed no
evidence of waning
immunity.
This vaccine confers
protection only against
EFFICACY OF VACCINES
Participants who were already positive to any
vaccine HPV types before vaccination
acquired protection against disease caused
by other vaccine types.
Additionally, 99–100% efficacy was reported
against vaccine-type related genital warts,
vaginal intraepithelial neoplasia and vulvar
intraepithelial neoplasia.
EFFICACY OF VACCINES
Immunogenicity studies in females aged 9–15 years showed antibody titers non-inferior to those aged 16–26 years.
In a combined analysis of all participants over 3 years and a subset through 5 years, efficacy against vaccine-HPV type disease was 95.8% and efficacy against vaccine-type-related CIN or external genital lesions was 100%.
Longer follow-up studies are under way.
DOSAGE AND SCHEDULE
The vaccine dose is 0.5 mL given
intramuscularly, either in the deltoid muscle or in
the antero-lateral thigh.
It is available as a sterile suspension for
injection in a single-dose vial or a prefilled
syringe.
HPV vaccines can be given simultaneously with
other vaccines such as Hepatitis B and Tdap.
At present, there is no data to support the use of
boosters.
DOSAGE AND SCHEDULE
The recommended age for initiation of vaccination is 9–12 years.
Catch-up vaccination is permitted up to the age of 26 years.
A total of three doses at 0, 2 and 6 months are recommended with Gardasil™ or 0, 1 and 6 months with Cervarix™ (minimum interval of 4 weeks between the first and the second dose, 12 weeks between the second and third dose and 24 weeks between the first and third dose).
DOSAGE AND SCHEDULE
If the HPV vaccine schedule is interrupted,
the vaccine series need not to be restarted.
If the series is interrupted after the first dose,
the second dose should be administered as
soon as possible, with an interval of at least
12 weeks between the second and third
doses.
If only the third dose is delayed, it should be
administered as soon as possible.
SIDE EFFECT AND CONTRAINDICATIONS
The most common adverse reactions are local reactions like pain (mild to moderate) in 83%, swelling with erythema in 25% and systemic adverse effects such as fever in 4% of the vaccinees.
No serious vaccine-related adverse events have been reported.
The HPV vaccine is currently not licensed for use in female patients younger than 9 years or older than 26 years or for use in male patients.
SIDE EFFECT AND CONTRAINDICATIONS
It is contraindicated in people with a history of immediate hypersensitivity to yeast or to any vaccine component.
The vaccine should be deferred in patients with moderate or severe acute illnesses.
The vaccine may be administered in a sitting or lying down position and the patient should be observed for 15 min post-vaccination for syncope.
SIDE EFFECT AND CONTRAINDICATIONS
The vaccine is not recommended for use in pregnant women.
Although it has not been causally associated with adverse outcomes of pregnancy, data are limited.
Any exposure to the vaccine during pregnancy must be immediately reported.
Lactating women and immunosuppressed female patients can receive the vaccine.
The efficacy and the degree of immune response could be poor in the immunosuppressed group.
HPV VACCINATION IN MALE
HPV vaccine is not licensed for use among males in India.
Efficacy studies among males are under way.
Australia is the first country to approve the quadrivalent HPV vaccine in males (between 9 and 15 years old), and the vaccine was approved for administration to males between the ages of 9 and 26 years in other developed nations.
IAP RECOMMENDATIONS
The Indian Academy of Pediatrics Committee on Immunisation (IAPCOI) recommends offering HPV vaccine to all females who can afford the vaccine (Category 2 of IAP categorisation of vaccines).
The Advisory Committee on Immunization Practices currently recommends routine vaccination of females aged 11–12 years with three doses of the HPV vaccine.
Vaccination can be given to females as young as 9 years as well as in those aged 13–26 years who have not previously completed vaccination.
CONCERN AND SAFETY
The primary obstacle to HPV vaccination is
financial.
Because of the high cost of the present
vaccines, the affordability and accessibility of
these vaccines is a major concern for a mass
vaccination program in developing countries
like India.
CONCERN AND SAFETY
One study in India has been conducted by the State governments in collaboration with the Indian Council of Medical Research (ICMR) and PATH for operational feasibility .
The other was a clinical trial to investigate the immunogenic efficacy of two doses (6 months apart) compared with the conventional three doses (0–2–6 months) of Gardasil.
There were allegations in the media of vaccine-caused death of four girls in north India, and the Union Government suspended both studies and initiated enquiry into the safety of both vaccines.
CONCERN AND SAFETY
The causes of death have been scrutinized by the State Government and reported to ICMR and DCGI; all were satisfied that no deaths were related to the vaccine.
The vaccines continue to remain as a licensed product approved by the DCGA.
To date, no deaths have been causally associated with HPV vaccination in India or elsewhere.
LACUNAE AND FUTURE
More research is needed regarding duration of protection induced by these vaccines, need for boosters, effect on prevalence and incidence of HPV types included in the vaccine.
The efficacy in female patients older than 26 years and in male patients, the role of routine HPV vaccine in males for prevention of genital warts and emergence of other rarer HPV types after the current common types are controlled has to be studied in detail.
LACUNAE AND FUTURE
The effect on cervical cancer screening practices, safe sex behavior and further economic analysis are a few questions to be answered in the future.
As prophylactic, vaccines will be effective pre-exposure to virus and, hence, the target population for vaccination will be 9–10-year-old pre-pubertal girls, but this will raise cultural and social issues.
There is an urgent need to conduct epidemiological studies in countries like India on the long-term efficacy, logistics and economics of universal HPV vaccination in eligible females.

NATIONAL CANCER CONTROL PROGRAMME
The National Cancer Control Programme for India was formulated in 1984 with four major goals:
1. Primary prevention of tobacco related cancers.
2. Early detection of cancers of easily accessible sites
3. Augmentation of treatment facilities, and
4. Establishment of equitable, pain control and palliative care network throughout the country.
NATIONAL CANCER CONTROL PROGRAMME
National programme for prevention and control of Diabetes, cardiovascular disease and stroke (NPDCS) was initiated in 2010.
National cancer control programme (NCCP) has been integrated with NPDCS to formulate a national programme for control of cancer, Diabetes, cardiovascular disease and stroke (NPCDCS) in 2011.
The focus of NPCDCS is on promotion of healthy lifestyle, early diagnosis and management.

NCRP began with a population based cancer registries (PBCRs) at Bangalore, Chennai, Mumbai and hospital-based cancer registries (HBCRs) at Chandigarh, Dibrugarh, and Thiruvananthapuram.
NATIONAL CANCER REGISTRY PROGRAMME( NCRP)
NCRP, it has been now been extended to cover other common noncommunicable diseases under the National Centre for Disease Informatics and Research (NCDIR) under the ICMR in March 2011.
The broad and overall objectives of the NCDIR is to sustain and develop a national research data-base on cancer, diabetes, CVD and Stroke
The current thrust areas of NCDIR are cancer registries, patterns of care and survival studies (POCSS) and development of software applications programmes.
NATIONAL CANCER AWARENESS DAY
Cancer Awareness day was first observed on 7–

CONCLUSION
HPV vaccination is for primary prevention (serotype-specific with limited cross-protection) of carcinoma cervix.
A cost-effective second-generation HPV vaccine is needed for developing countries to address various issues specific to the region.
However, till such time, secondary prevention through periodic cervical cancer screening should be in place to use the existing infrastructure and cost-effective screening methods such as Pap smear and HPV DNA tests.
CONCLUSION
There is no risk of getting an HPV infection
from the vaccine as the vaccine does not
contain live virus.
HPV vaccination and regular cervical
screening is the most effective way to
prevent cervical cancer.
