Early detection
Downstage cancer to

improve outcomes and
reduce mortality

Setting up an Integrated Screening Program in existing
government run hospitals and Primary health centers:
Problems…

 Health care facilities are not easily accessible
to rural poor population
 Are over utilized, understaffed and
underfunded
 An asymptomatic woman is unlikely to make
use of a screening program in such a setting

Well Woman Clinic Concept
 Integrated cost effective approach of
combining a routine health check up with
screening and early diagnosis of Breast and
Gynecological cancers delivered through fixed
site or mobile clinics

GOALS…
 To promote the concept of free standing Well
Woman’s Clinics to improve outcomes from
lethal cancers affecting women
 The WCF clinic and the strategy adopted for
screening should serve as a model for
establishment of a chain of similar clinics to be
funded by NGO’S and local and national charities.

SCREENING AND EARLY CANCER DETECTION OF BREAST AND
GYNECOLOGICAL CANCERS

BACKGROUND

BREAST CANCER
 Breast cancer is the most prevalent cancer in
the world today. 4.4 million Women are alive
today in whom breast cancer was diagnosed
within the last five years
 Over 1 million new cases of Breast cancer will
be reported worldwide

 LOW RESOURCE COUNTRIES ARE BURDENED
WITH 50% OF BREAST CANCER CASES AND 60%
OF DEATHS DUE TO BREAST CANCER

Global cancer statistics, CA Cancer J Clin
2011;61;69-90;

 Breast cancer is the most frequently
diagnosed cancer and the leading cause of
cancer death among females, accounting for
23% of the total cancer cases and 14% of the
cancer deaths.

Breast Cancer
 Downstage Breast Cancer from Stage 3 and 4
to Stage 1 and 2A reducing mortality from
20-57% (before intervention) to 82-92% (after
intervention)

CERVICAL CANCER
 There are 1.4 million women worldwide with
cervical cancer
 7 million worldwide may have precancerous
lesions that need to be identified and treated
before they turn cancerous and lethal
 The highest absolute numbers of cervical
cancer cases occur in Asia

Cervical Cancer
 Globally nearly 500,000 new cases of cervical
cancers are reported yearly with 285,000
deaths, about 85% of these cases occur in the
developing countries where screening
programs are not established

Cervical Cancer
Aim is to Prognosis: 5year
downstage survival
from Stage 3 Stage 1 A Micro invasive 99%
to 4 to Stage
1 to reduce Stage 1 B Small confined to 80-90%
morbidity cervix
and mortality
resulting Stage 3 and 4 Local and distant 15 to 40%
from cervical spread
cancer

SCREENING AND EARLY CANCER DETECTION
STRATEGY: CERVICAL CANCER

CERVICAL CANCER: SCREEN AND TREAT
APPROACH STRATEGY
 HPV DNA TESTING
 CRYOTHERAPY FOR SCREEN POSITIVE SMALL
LESIONS
 LEEP FOR LARGER LESIONS

STRATEGY: BREAST CANCER

BREAST CANCER SCREENING STRATEGY
 Screening Clinical Breast Examination

 Screen positive cases

 Ultrasound breast examination

 Fine needle Aspiration of palpable masses that appear
suspicious for cancer on ultrasound

Ultrasound: Advantages
 Portable equipment easy to transport and for use in mobile
clinics
 No need to recall for additional imaging evaluation as in
mammography
 Sonographic examination of the breast is better tolerated by
women due to lack of the need for breast compression
 Fine needle aspiration biopsy feasible: Procedure is
cytology based and similar to PAP smears. US is used as the
imaging guide to obtain the sample

Screening Mammography: Why not suitable
in low resource settings
 Expensive to set up
 Resource intensive modality
 Poor sensitivity in women with dense breasts
 Mammographic findings of breast masses and focal
asymmetry need additional sonographic evaluation
 Minimally invasive biopsy procedures for
mammographic findings requires stereotactic biopsy
equipment which are expensive and time consuming

Screening Mammography:
Limitations
 10-15% or higher recall rate is to be expected for
women undergoing screening mammography
requiring an additional clinic visit
 Breast compression required for mammography
involves patient discomfort, and may be less well
tolerated and accepted
 Telemedicine impractical
 FNAB[fine needle aspiration biopsy] is not an option
to sample abnormalities detected by this modality

STRATEGY: OVARIAN CANCER

Ovarian Cancer: Early detection
 Goff and others have reported that symptoms
that were associated with ovarian cancer were
pelvic abdominal pain, urinary
frequency/urgency, increased abdominal size and
bloating and difficulty eating/feeling full. These
symptoms are particularly significant if present
for less than year and present > 12 days per
month.

Ovarian Cancer: Early detection
 A symptom index was considered positive if any
of the following symptoms occurred > 12 times
per month and present for < 1 year:
Pelvic/abdominal pain, increased abdominal
size/bloating, difficulty eating/feeling full. In
the confirmatory sample the index had a
sensitivity of 56.7% sensitivity for early disease.
Specificity was 90% for women > 50 years

ENDOVAGINAL SONOGRAPHY
NORMAL OVARY OVARIAN CANCER

STRATEGY: ENDOMETRIAL CANCER

ENDOMETRIAL CANCER EARLY
DETECTION
 Assessment of the endometrial stripe in
women with post menopausal bleeding

ENDOVAGINAL SONOGRAPHY
ENDOMETRIAL CANCER
NORMAL ENDOMETRIAL LINING

FUTURE STRATEGIES

 BREAST CANCER: AUTOMATED WHOLE BREAST
SCREENING ULTRASOUND MAY BE A VIABLE
ALTERNATIVE TO SCREENING MAMMOGRAPHY
AND NEEDS TO BE STUDIED TO TEST EFFICACY
AND COST EFFECTIVENESS

FUTURE STRATEGIES…….
 CERVICAL CANCER VACCINE……
 USE OF TUMOR MARKERS FOR EARLY
DIAGNOSIS OF OVARIAN CANCER…….

Proposed Clinic locations
 Nova Andradina, Mato Grosso do Sul, Brazil
 Phnom Penh, Cambodia
 Calcutta, India

TARGET POPULATION
 Each clinic would serve an approximate target
population of about 9000-15000 eligible women

EARLY CANCER DETECTION STRATEGY
SCREENING EXAMINATION
 Cervical cancer: Age group: 30 through 59 at three
year intervals
 Breast cancer: Age group: 35 through 65 at three
year intervals
DIAGNOSTIC EXAMINATION IN SYMPTOMATIC WOMEN
 Ovarian and Endometrial cancer: Age group 50
through 69 years

EARLY CANCER DETECTION STRATEGY
 BREAST CANCER: CBE and BUS followed by FNAB
of screen and Ultrasound positive cases
 CERVICAL CANCER: HPV DNA followed by
Cryotherapy or LEEP : Screen and treat approach
 Ovarian and Endometrial cancer: Endometrial
and Transvaginal ovarian sonography in
symptomatic women

EMR and Patient data entry

RESEARCH COMPONENT
Data collection and measurement
 Population registry of the community served to determine
number of eligible women in the target population
 Compliance rate: To determine potential for effectiveness
of the program
 Prevalence rate at initial screening for breast and cervical
cancer: Provides estimates of sensitivity, lead time and rate
of interval cancers, sojourn time and predictive value

 Stage distribution of screen detected breast and cervical
cancers: Indicates potential for reduction in absolute
screen-detected cancers rate of advanced cancers. The
same for Endometrial and ovarian cancer in the
symptomatic population
 Rate of advanced breast and cervical cancers: Early
surrogate of mortality. The same for Endometrial and
ovarian cancer in the symptomatic population
 Sensitivity, specificity, Positive predictive value for each
screening method

Confounding variable/study
limitations:
 An organized screening program is a novel healthcare
intervention in these communities; hence
participation of eligible women in the target
population is the confounding variable. A screening
program which essentially aims to draw in
asymptomatic women in a low resource setting will
face a challenge of convincing women who are
otherwise healthy to attend a health clinic given the
social constraints on women with limited financial
resources and maternal obligations.

 The screening strategy has to be adapted to conform
to local and national guidelines making it difficult to
test efficacy of a similar strategy combined
screening program because of inherent differences
in methodology of cancer screening necessitated by
local and national guidelines’
 The study design is not that of a randomized clinical
trial so mortality reduction cannot be ascertained
from implementation of such a screening strategy

Timetables/project management
 The study period will be for a total of six years.
 The investigators will include select members of
the Medical Advisory board, Clinic director, a
physician from the partner organization
 Project will be managed by local clinic
administrative and medical team in consultation
with the medical advisory council members who
are listed as Clinical Investigators

Performance Indicator Acceptable outcome
Participation rate 70%

Additional Imaging at time of screening 5%

Pre treatment diagnosis of malignancy 70 %

Insufficient FNA results 25%

Benign to malignant ratio 50 %

Re invitation within specified period 95%

Reporting of findings:
 Initial data will be analyzed at the end of three years
and presented at appropriate scientific meetings
 Final data at the end of a six year study period will
be analyzed and published in peer reviewed journals.
