What is gynecologic cancer ?
Gynecologic cancer is the uncontrolled growth and spread of abnormal
cells originating in the female reproductive organs, including the cervix,
ovaries, uterus, fallopian tubes, vagina and vulva.
What causes gynecologic cancer ?
Biomedical research has discovered that some genes, called oncogenes
and tumor suppressor genes, promote the growth of cancer . You can
acquire these genetic mutations during life (e.g. through smoking, aging
or environmental influences) or you can inherit these mutations from
your parents or grandparents.
Can gynecologic cancer be prevented?
Diet, exercise and lifestyle choices play a significant role in the
prevention of cancer . Additionally, knowing your family history can
increase your chance of early diagnosis and can help you take action
towards prevention. Regular screening ...

Abstract
Genetic testing for breast and ovarian cancer has been publicly available since the mid-1990
discovery of two breast/ ovarian cancer susceptibility genes named BRCA1 and BRCA2.
Although many professionals say that genetic testing may be the best available preventative
medicine breakthrough, controversy abounds over whether the medical benefits of BRCA1/2
mutation testing outweigh the psychological and financial costs. This study uses three models to
analyze 104 women’s responses to a self-designed questionnaire: a logit regression model, an
ordered probit regression model, and a cost effectiveness model. The regression models use
questionnaire responses to learn how the benefits and costs of genetic testing affect a woman’s
decision to ...

Abstract : Recent observational studies and clinical trials that have investigated the relation-
ship between carotenoids (or diets rich in these compounds) and cervical, breast, ovarian , and
colorectal cancer have increased knowledge in this area. Although epidemiological studies
suggest a protective association, five randomized controlled trials testing the effect of beta-
carotene supplementation on regression of cervical dysplasia, a preneoplastic lesion, did not
find an effect on rate of regression. In the Women’s Healthy Eating and Living (WHEL)

SURGERY FOR OVARIAN CANCER
DAVID M. GERSHENSON and J. TAYLOR WHARTON
Ovarian cancer , one of the most challenging diseases
facing gynecologic oncologists, is currently the second
most common malignancy of the female genital tract in
the United States. According to the American Cancer
Society,
1
25,200 new cases of ovarian cancer and 14,500
deaths from the disease in the United States were esti-
mated for 1999.
Surgery remains the cornerstone in the management
of ovarian cancer . This chapter reviews current prac-
tices in surgical management, including primary sur-
gery, secondary procedures, second-look laparotomy,
and surgery for complications of ovarian cancer and its
therapy. Although many of the concepts and principles
apply equally to all three broad categories of ovarian
cancer —epithelial, germ cell, and sex cord–stromal—

WHEREAS:
Ovarian cancer has long been called a “silent killer,” because it occurs in an
organ deep in the pelvis and produces vague symptoms that may be
dismissed; and
WHEREAS:
Recent studies have identified factors that put women at higher risk of
developing ovarian cancer , such as a family history of breast and ovarian
cancer , no pregnancies or infertility, no history of oral contraceptive use,
or the use of high-dose estrogen for long periods without progesterone;
and
WHEREAS:
Early detection remains the most valuable weapon against ovarian cancer ;
however, there is not a simple early detection method. Subtle symptoms
include pelvic and abdominal pressure; bloating; pain, swelling or
discomfort; unexpected weight gain or loss, especially weight gain in the
abdominal area; gastrointestinal problems; and back pain and fatigue.

THE LANCET • Vol 359 • February 16, 2002 • www.thelancet.com
Background New technologies for the detection of early-
stage ovarian cancer are urgently needed. Pathological
changes within an organ might be reflected in proteomic
patterns in serum. We developed a bioinformatics tool and
used it to identify proteomic patterns in serum that
distinguish neoplastic from non-neoplastic disease within
the ovary.
Methods Proteomic spectra were generated by mass
spectroscopy (surface-enhanced laser desorption and
ionisation). A preliminary “training” set of spectra derived
from analysis of serum from 50 unaffected women and
50 patients with ovarian cancer were analysed by an
iterative searching algorithm that identified a proteomic
pattern that completely discriminated cancer from non-
cancer . The discovered pattern was then used to classify

The treatment of advanced ovarian cancer has
evolved over the past 20 years. Although effective
early diagnosis continues to be elusive and the man-
agement of relapsed ovarian cancer does not offer a
cure, new therapeutic advances offer many women
longer disease-free intervals and improved quality of
life with disease.
The focus of this program has been to explore the
management of advanced ovarian cancer in ways that
would promote optimum disease response to various
antitumor agents and maximize quality of life during
the disease trajectory.

A resident asks.
Why should a primary care doctor know about breast or ovarian cancer genetics?
Key Points :
Family history is an important tool in the assessment of breast and ovarian cancer
risk
Women are concerned about breast cancer and often over-estimate their risk.
They may view themselves as candidates for genetic testing when their likelihood
of a positive test is minimal.
BRCA1/2 mutations are rare and there are few data to assess the outcome
benefits of interventions to reduce risk
Testing for BRCA1/2 is mentioned frequently in the medical and lay press. Your

SCOPE OF THE PROBLEM
Ovarian cancer is the seventh most common
malignancy diagnosed in Connecticut women,
accounting for 3.5 percent of invasive cancers. It
is the leading cause of death from gynecological
malignancies, accounting for about 5 percent of
cancer deaths among Connecticut women or 200
deaths each year.
Stage at Diagnosis and Relative Survival
Rate
Ovarian cancer has the worst prognosis of
any gynecological cancer , because it produces no
symptoms until it is at an advanced stage. In the
United States, cancer incidence and survival
rates are reported through the SEER program
(see Appendix A). Between 1992 and 1997, 26
percent of ovarian cancers were localized at

Ovarian Cancer
What Is Cancer ?
Cancer is a group of many related diseases. All forms of cancer involve out-of-control growth
and spread of abnormal cells.
Normal body cells grow, divide, and die in an orderly fashion. During the early years of a
person's life, normal cells divide more rapidly until the person becomes an adult. After that,
normal cells of most tissues divide only to replace worn-out or dying cells and to repair injuries.
Cancer cells, however, continue to grow and divide, and can spread to other parts of the body.
These cells accumulate and form tumors (lumps) that may compress, invade, and destroy normal
tissue. If cells break away from such a tumor, they can travel through the bloodstream, or the
lymph system to other areas of the body. There, they may settle and form "colony" tumors. In
their new location, the cancer cells continue growing. The spread of a tumor to a new site ...

[40,1 KB]
From [www.sciencenews.org] Last viewed: 07.09.2006
Ovarian cancer usually grows for about 2 years before it produces symptoms, a large
British study indicates. The delay explains why doctors diagnose only about one-fourth of
cases before the disease has spread to other tissues, according to the researchers.
A sensitive blood test, used in the study to indicate when disease originated, could be
widely employed to screen postmenopausal women for ovarian cancer , the researchers
assert. Such screening could detect more cases early, when treatments are most effective,
they say.
When the cancer is detected while confined to the ovaries, 90 percent of women survive at
least 5 years, says Robert C. Bast Jr., an oncologist at the University of Texas M.D. Anderson
Cancer Center in Houston. Only 15 to 20 percent of women in whom the cancer has spread
beyond the pelvic cavity survive 5 years.

[40,2 KB]
From [www.sciencenews.org] Last viewed: 07.09.2006
For the female body, ovulation is hard work. An ovary secretes hormones, produces an egg,
thrusts it through a wall of tissue, and afterward repairs the rupture. Four weeks later, the
process repeats.
Scientists have suspected that the frequency and rigor of tissue rebuilding can lead to ovar-
ian cancer because, after each ovulation, the manufacture of new cells requires synthesis of
DNA. This cell proliferation is thought to open the door to mutations in the p53 gene, which
produces one of the body’s natural cancer fighters.
Now, a new study bolsters this incessant-ovulation theory (SN:10/31/92, p. 298) and its
corollary that pregnancy, breast feeding an infant, or taking oral contraceptives lessens a
woman’s cancer risk by giving her welcome rests from ovulation and easing wear and tear on
the ovaries.
The key element in this theory is the p53 gene, which normally blocks cell division when a
cell has sustained ...

Reducing the risk of ovarian cancer
Birth control pills lessen risk of ovarian cancer even among women carrying harmful muta-

A team led by researchers at the University of Toronto and Women’s College Hospital in
Toronto compared 207 patients who had ovarian cancer and a mutated BRCA gene with 161 of
these women’s sisters who didn’t have the cancer . The patients averaged 54 years old and the
sisters 52 years old. Half of the patients reported having used birth control pills at some
point in their lives, on average for 4 years. Among the 50 sisters without cancer who carried
the BRCA1 mutation, 77 percent had taken oral contraception, averaging 5 years on the pill.
Only three of the sisters showed the BRCA2 mutation.
The data demonstrated that risk of ovarian cancer decreases as years of birth-control pill ...

Gene therapy for breast, ovarian cancer
A novel gene therapy technique may one day hold out promise for women with breast or
ovarian cancer .
Naoto T. Ueno of the University of Texas M.D. Anderson Cancer Center in Houston and his
colleagues knew that 20 to 30 percent of ovarian and breast cancer patients have a gene, called
HER-2/neu, that is hyperactive. They also knew that women with this overactive gene tend to
have a poor therapeutic outlook. “The cancer is aggressive,” Ueno says.
The team wanted to see if it could slow the cancer by countering the action of HER-2/neu in
cancer cells. To do that, the researchers turned to another gene, E1A, which is thought to work
by turning off HER-2/neu. They had previously used the E1A gene to treat mice with ovarian
cancer .
The Texas team recruited 12 people with advanced ovarian or breast cancer . Each recruit
received weekly injections ...
