July 27, 2006, GCF 2006 GCAM Tool Kit
Dear Colleagues and Friends,
The Gynecologic Cancer Foundation's (GCF) 15th anniversary provides a
special opportunity to make this year's Gynecologic Cancer Awareness Month (GCAM) the most effective to date. To help you achieve this goal, please
click here to view the 2006 GCAM Tool Kit. In addition to promoting general gynecologic cancer education and awareness for our September campaign, GCF will address issues related to Familial Breast-Ovarian Cancer Syndrome.
Women stricken with this syndrome - caused by genetic mutations in the Breast Cancer 1 (BRCA1) gene or Breast Cancer 2 (BRCA2) gene - have an 80 percent lifetime risk of developing breast cancer and a 20 to 40 percent chance of developing ovarian cancer (with a mutation in the BRCA1 gene) or a 10 to 20 percent chance of developing ovarian cancer (with a mutation in the BRCA2 gene).
These statistics may sound bleak; however, options are available for women who are considered high risk due to family history or positive genetic testing. These options include: clinical monitoring (mammograms, a blood test, pelvic exams and ultrasound), medication, life-style changes and preventative surgery.
The link between ovarian cancer and breast cancer is quite profound. We urge you, on behalf of GCF, to highlight this important link during GCAM, and once again during National Breast Cancer Awareness Month in October.
We would be remiss if we did not highlight a major advance in cancer prevention that should be part of our September observance. The first vaccine for a cancer-cervical cancer-was recently approved by the FDA. GCF and SGO have an aggressive education agenda aimed at speeding widespread adoption of the vaccine program. For more information, visit GCF's National Cervical Cancer Public Education Campaign Web site at
www.cervicalcancercampaign.org. Also, to review SGO's position statement on the cervical cancer vaccine, log onto the SGO Web site at
www.sgo.org.
As always, thank you for your efforts to educate women about gynecologic cancers during GCAM and the remainder of the year.
Sincerely,
Karl C. Podratz, MD, PhD

March 9, 2006, Protect the Ovarian Cancer Research
Program at the Department of Defense
Dear OCAN members and advocates,
This month we have an important and easy opportunity for ovarian
cancer advocates to take action and make a difference for ovarian
cancer.
Please read about how you can help protect the Ovarian Cancer Research
Program at the Department of Defense. Just follow the links to the
Alliance website to take action and contact your Congress members.
Taking action makes a difference and takes less than 5 minutes of your
time.
Ask Your Elected Officials to Sign the “Dear Colleague” Letter on
Research Funding
Issue background: Every year we have to fight to secure funding for
the Ovarian Cancer Research Program at Department of Defense (DoD). We
are asking for $15 million for the program in Fiscal Year (FY) 2007.
This much-needed and long-pursued $5 million increase was granted by
the House of Representatives last year, but the Senate provided only
$10 million. In the end, the final funding bill unfortunately
reflected the Senate allocation.
Congressional Status: Congressional Champions of the cancer community
are circulating a “Dear Colleague” Letter to their fellow lawmakers on
behalf of the ovarian, breast and prostate cancer DoD research
programs. Members of Congress in both the House and the Senate can
pledge their support by signing this letter, but likely will not do so
unless they are requested to do so by their constituents. The House
letter is open this week and the Senate letter will open the third
week of March. You will receive another e-mail alert when the Senate
letter opens.
Take Action: Call or write your Senators and Representative and tell
them to sign the DoD Cancer Research Programs’ “Dear Colleague”
letter. All the information and details are available at
www.ovariancancer.org/action.
Thank you for taking action to support ovarian cancer research and
legislation that support our national battle against ovarian cancer.
Remember you can review issue briefs on all Action Alerts and the
federal budget process at the Alliance’s Legislative Action Center
www.ovariancancer.org/advocacy. Please share this e-mail with your
friends, family and group members. Feel free to contact the Alliance
with any questions at advocacy@ovariancancer.org or 202-331-1332.

July 27, 2005, Kentucky Derby Festival Press Office, $31,000 raised through Meijer Derby Festival races
 Team Force raised money for Ovarian Awareness of Kentucky
This year’s Meijer Derby Festival Marathon/miniMarathon helped participating runners raise more than $31,000 for seven designated Official Charities. The Derby Festival in 2005 implemented a new charity module on its race website – www.derbyfestivalmarathon.com. – that allowed runners to more easily navigate the process of designating a particular charity for fund-raising. Runners were able to set a fund-raising goal online, as well as email potential donors, keep track of donations and send “thank-you” responses.
The Derby Festival designated seven Official Charities of the Meijer Derby Festival Marathon/miniMarathon: Cystic Fibrosis Foundation, Dream Factory of Louisville, Ovarian Awareness of Kentucky, St. Jude Children’s Research Hospital, Visually Impaired Preschool Services and the WHAS Crusade for Children.
The Kentucky Derby Festival annually helps raise more than $200,000 for charitable causes and its new race online charity module proved to be a successful tool for runners seeking to not only give of themselves physically, but give to others as well.
2004 Lippincott Williams & Wilkins, Immunological treatment of ovarian cancer
Development of immunological treatments for ovarian cancer
has not been a conspicuous success story over the past few
years. Only a handful of clinical trials have reported
immunological responses, and correlation with clinical benefit
has been elusive. Several recent studies presented in this
review, however, point to a revival of optimism for the
development of novel immunotherapeutic strategies. More...
June 6, 2005, Courier Journal (by
Scheri Smith), Ovarian cancer survivors celebrate
Star Prestigiacomo of Germantown knew nothing about ovarian cancer until it
invaded her life four years ago.
Prestigiacomo said she was stunned when doctors found a football-sized tumor in
one of her ovaries.
"I wasn't even sick," she said. "I never thought anything about it."
Prestigiacomo said she found peace and learned about the disease as a member of
Ovarian Awareness of Kentucky, a support group for cancer patients and their
families.
The group, a nonprofit organization with an office in Norton Suburban Hospital,
celebrated yesterday at Des Pres Park, on Lowe Road near Taylorsville Road,
with a picnic for cancer survivors.
Prestigiacomo and other survivors shared their stories with friends and family
at the picnic, which drew about 50 people.
Jill Doimer of the Eastwood area, a co-founder of the group, said that giving
women support when they are found to have cancer has been shown to improve
their lives.
"Statistics say that if you're involved in a support group, then you have a
better quality of life," Doimer said. "We have to keep this thing going because
we've all been touched by it."
And getting women to talk about the disease is one of the best ways to create
awareness, said SuzAnne Caraway, a member of the group's board. Caraway, who
lives near Springhurst and whose mother has had more than 200 treatments for
the disease, said that many women don't realize that they aren't being tested
for ovarian cancer during their annual gynecological exams.
"I think that's the biggest farce," she said. "They think everything's fine,
but it's not."
According to the group's Web site, ovarian cancer, the deadliest of the
gynecologic cancers, is the fifth-leading cause of cancer death among U.S.
women. Ovarian cancer occurs in 1 out of 58 women, according to the American
Cancer Society.
Symptoms of the disease include abdominal pressure, bloating, nausea,
indigestion, constipation, diarrhea, frequent urination, abnormal bleeding,
unusual fatigue, unexplained changes in weight and shortness of breath.
Caraway's mother, DiAnne Estes, who lives near Brownsboro Road, said that many
times women just don't think ovarian cancer is something they should be
concerned with. Estes, whose cancer has been in remission for a couple of
years, said she's not embarrassed to tell other women that the disease even
caused her to have a colostomy bag for a time.
"It's not a pretty picture," she said. "People need to know that it can happen
to them."
But belonging to the support group and educating others isn't always "a
downer," Estes said.
The best advice that survivors can give is for women to know their bodies,
Caraway said.

survivors at Des Pres Park in Louisville. Estes spoke frankly about the effects
of the disease. "It's not a pretty picture," she said. (PHOTOS BY CHRIS HALL,

February 15, 2005, WHAS News, Students raise money for cancer-stricken teacher
(view
story online)
They are counting money. Dollars, tens, twenties, quarters, a hundred dollars
over here. And when many of the 1,100 students at Crosby Middle School raise
their hands in class, a light blue bracelet reminds them of a teacher who
should be here.
Sixth grade science teacher Deirdre Edwards is missing from the classroom.
"I was thinking I need to bring some in," says sixth grader Jeffrey Owens.
"She's one of the fantastic teachers I've ever had. I just really want to help
her."
"I miss her a lot. She would always make something make sense," says student
Emily Reid.
Edwards, 33, stunned the school with her news. She has had a recurrence of an
aggressive ovarian cancer. She's been gone from the classroom for a few weeks
after major surgery February 1.
Students at Crosby Middle School are wearing these bracelets in honor of teacher
Dierdre Edwards, who has ovarian cancer "I experienced stomach pain in January
of last year," she explains. "When they opened me up there was cancer all along
my abdominal wall. The doctor removed all he could."
She was first diagnosed a year ago. But the cancer had been in remission. The
fundraising is to get her to the M.D. Anderson Cancer Center in Houston for an
extended stay. Five thousand dollars has been raised so far. She was in
disbelief.
"They have just lifted a huge worry off of me. I'm overwhelmed by the support
they've shown. I'm speechless," says Edwards. "And I know some of my students
don't have all that much money. For them to give means the world to me."
Her fellow teachers say it also been a huge lesson to everyone, including the
students.
"They've had a lot of questions, don't know what ovarian cancer means," says
Crosby teacher Annette Ellis.
Edwards will be leaving Tuesday with her husband, Frank. Her 3-year-old son
stays behind with relatives. The school will keep raising money as she's away.
She is not on the school's health insurance plan, and since her treatments in
Houston may be experimental, insurance coverage through her husband's plan is
unlikely.
We asked her if she had a message for her class.
"I hope you guys are being good, learning science and doing best you can, like I
know you can," she says.
And at Crosby, they think of her every time they write lessons and see that
bracelet.
"We love you, Ms. Edwards, and we miss you and we hope you get well soon," says
sixth grader Stephanie Wilson.

February 3, 2004, NY Times, New Cancer Test Stirs Hope and Concern by Andrew
Pollack
Jill Doimer's mother died in 2002 from ovarian cancer, detected too late to be
effectively treated. So Ms. Doimer is eagerly awaiting the introduction of a
new test that holds the promise of detecting early-stage ovarian cancer far
more accurately than any test available now, using only blood from a finger
prick. Not only does she plan to be tested, but an advocacy group she helped
found, Ovarian Awareness of Kentucky, also intends to spread the word to women
and doctors. "If it's going to happen to me or anyone I know, I want it to be
caught at an early stage," said Ms. Doimer, who lives in Louisville. The new
test, expected to be available in the next few months, could have a big effect
on public health if it works as advertised. That is because when ovarian cancer
is caught early, when it is treatable by surgery, more than 90 percent of women
live five years or longer. But right now, about three-quarters of cases are
detected after the cancer has advanced, and then only 35 percent of women
survive five years. The test is also the first to use a new technology that
some believers say could revolutionize diagnostics. It looks not for a single
telltale protein - like the prostate-specific antigen, or P.S.A., used to
diagnose prostate cancer - but rather for a complex fingerprint formed by all
the proteins in the blood. Similar tests are being developed for prostate,
pancreatic, breast and other cancers. The technique may work for other diseases
as well. "I've been in cancer research for 40 years and I think it's the most
important breakthrough in those years," said Dr. John S. Kovach, director of
the Long Island Cancer Center at Stony Brook University. "I think in 10 years
ladies will have blood tests instead of a mammogram for breast cancer." Some
experts, however, say that the technique, while promising, is still unproved.
They say the ovarian test in particular has not been adequately validated and
is being put on the market prematurely through a route that does not require
approval by the Food and Drug Administration. If the test is not accurate, they
say, it could result in unnecessary surgery for biopsies or ovary removal for
many women. "Certainly there's no published work that would make me tell a
woman she should get this test," said Dr. Nicole Urban, head of gynecologic
cancer research at the Fred Hutchinson Cancer Research Center in Seattle. Three
statisticians from the M. D. Anderson Cancer Center in Houston analyzed data
put on the Internet by the test developers and say they found various
inconsistencies. "We're saying that on the basis of the data they posted, no,
we don't believe this works," said one of the statisticians, Dr. Keith A.
Baggerly, assistant professor in the department of biostatistics and applied
mathematics. The test, called OvaCheck, was developed by Correlogic Systems
Inc., of Bethesda, Md., with scientists from the National Cancer Institute and
the Food and Drug Administration. Correlogic Systems has licensed the test to
Quest Diagnostics of Teterboro, N.J., and Laboratory Corporation of America
Holdings, known as LabCorp, of Burlington, N.C., the nation's two biggest
clinical laboratory companies. Quest Diagnostics and LabCorp, which will
compete, say they expect to begin offering the test in the next few months. The
price is expected to be $100 to $200. Quest Diagnostics and LabCorp will
analyze blood samples sent by doctors, rather than sell test kits to doctors
and hospitals. Tests performed at a central location do not require F.D.A.
approval. Diagnostic companies say such "home-brew" tests are a common way to
make them available quickly and that for some tests it would not be
economically practical to conduct the clinical trials needed for F.D.A.
approval. At times, though, the agency has had concerns that such tests have
not been adequately validated. The agency recently ordered Roche to take a
complex genetic test off the market until it could be approved by the agency.
Dr. Emmanuel F. Petricoin III, an agency scientist who helped develop OvaCheck,
said the criticisms of it were based "in some instances on not understanding
the entirety of the science." And executives at Correlogic Systems, Quest
Diagnostics and LabCorp say it is not fair to cite lack of validation because
they are validating the test now. Gary Samuels, a spokesman for Quest
Diagnostics, said his company and LabCorp were each testing the same 1,000
samples to see if they got the same results, a validation process he called
"lengthy and meticulous." He said Quest Diagnostics expected to decide by the
end of the month whether the test was reliable enough to market. Brad Smith,
executive vice president for public affairs at LabCorp, agreed, saying, "If
we're not comfortable with it, it won't launch." Many companies and academic
labs have joined the race to find so-called biomarkers, blood components like
proteins or lipids that can signal disease. "There are very few diseases, when
you really go through it, that we can diagnose with a simple blood or urine
test," said Dr. Gordon Ringold, chairman and chief executive of SurroMed, a
Menlo Park, Calif., company looking for such markers. Until now, said Dr.
Howard Schulman, vice president of research and development at SurroMed,
"biomarker discovery has relied on knowing everything possible about the
disease," searching for proteins involved in the cause of the disease. But
results have been sparse. In the last decade only about 10 proteins have been
the basis for diagnostic tests approved by the F.D.A. For instance, Matritech
Inc., a company in Newton, Mass., sells a bladder cancer screening test that
looks for a protein called NMP22. A single biomarker may not work because a
disease is heterogeneous or because more than one condition can cause a
protein's level to rise, resulting in false positives. That is the case with
the P.S.A. for prostate cancer. So, now, the search for biomarkers is shifting.
Instead of trying to understand disease mechanisms, some companies are using
new technology called proteomics to screen cells or blood rapidly, looking for
proteins present in diseased people but not in healthy ones. Similar efforts
are being used for genes and metabolites, substances like fatty acids made by
cells. Moreover, in many cases, scientists are trying to find not a single
marker but several that could be used together to get a more accurate reading.
OvaCheck goes a step beyond that. It analyzes patterns made by all the proteins
in the blood without even knowing what the proteins are. In the tests, proteins
in the blood sample are analyzed by a mass spectrometer, a complex machine that
can cost hundreds of thousands of dollars. The proteins are vaporized, given an
electric charge and propelled down a tube. How fast they make the trip depends
on their mass. The machine produces a squiggly graph that essentially shows the
distribution of masses in the blood sample. There are thousands of data points,
with spikes corresponding to particularly abundant proteins. Correlogic Systems
developed a computer program that analyzes these complex patterns and learns to
distinguish between blood from patients with cancer and blood from those
without. When the technique was first tried on 116 blood samples from women
whose disease status was already known, it correctly detected all cases of
ovarian cancer, including 18 in the earliest stage. It classified only 5
percent of the noncancerous samples as cancerous. When the results were
published in the medical journal Lancet in 2002, it suggested a powerful
testing method was at hand. "We think now that there is an entire ocean of
biomarkers that never before was known to exist," said Dr. Petricoin. He is
co-director of the clinical proteomics program run by the F.D.A. and the
National Cancer Institute with Dr. Lance A. Liotta, who helped develop the
ovarian test. Ovarian cancer, which causes about 14,000 deaths a year in the
United States, is now diagnosed with a test for a single protein called Cancer
Antigen 125. But CA-125 is best at detecting a recurrence of cancer or a
late-stage cancer, not a disease in the early stages. Vaginal ultrasound,
another often-used technique, is also not so good for early-stage disease,
experts say. But experts say OvaCheck must give virtually no false positives to
make it useful for general screening. Fifteen women out of 100,000 get ovarian
cancer each year, said Dr. Beth Y. Karlan, director of gynecologic oncology at
Cedars-Sinai Medical Center in Los Angeles. So if OvaCheck were used for yearly
checks on the whole population, even a 1 percent rate of false positives would
mean 1,000 false diagnoses for every 15 cases detected. Peter J. Levine,
president of Correlogic Systems, said for that reason, the test would be
recommended only for women at high risk for ovarian cancer, a population of
about 10 million in the United States. This includes women with relatives who
have had ovarian cancer, women who have had breast cancer, and women with
mutations in genes called BRCA1 and BRCA2 that indicate a high risk of breast
and ovarian cancer. Other experts said that women who tested positive would be
given the CA-125 test and vaginal ultrasound to try to confirm the diagnoses,
rather than being sent for surgery immediately. Yet another problem, some
experts said, is that the samples taken to test the technique so far have come
mainly from women who were scheduled for surgery, meaning their cancer had
produced noticeable symptoms. Dr. Petricoin conceded that it was unclear if the
test would work equally well for early-stage ovarian cancer that does not
produce symptoms, as is often the case. Some experts say they would not trust a
test in which the proteins being measured and their biological relationship to
cancer are unknown. "If you don't know what you're measuring, it's a dangerous
black-box technology," said Dr. Eleftherios P. Diamandis, head of clinical
biochemistry at Mount Sinai Hospital in Toronto. He said the rare proteins that
might indicate cancer were likely to be drowned out by abundant proteins in the
blood. "They are rushing into something and it could be a disaster," Dr.
Diamandis added. Dr. Petricoin countered that recent studies had shown that the
rare proteins adhere to more abundant blood proteins, so their concentration is
increased to detectable levels. And he said the failure to develop many
biomarkers so far showed how hard it was to identify specific proteins. "We
don't understand many of the basic mechanisms of cancer yet, and we think we
have knowledge of what markers to use?" Dr. Petricoin said. "It's false." Some
critics say that for the test to be accepted, the Lancet data must be
reproduced by others and the technique tested in larger trials. For instance,
Dr. Karlan of Cedars-Sinai said, a few years ago scientists were excited by
early results of an ovarian cancer test using a marker called LPA, but results
of a larger test were disappointing. LPL Technologies, a Cleveland company, is
still working to validate that test. The Lancet data could not be reproduced
exactly even by the test developers. They found that the mass spectrometer they
used, which was made for research, not high-volume work, produced different
patterns even when the same samples were tested on different days. So they
switched to a new machine. William E. Rich, president and chief executive of
Ciphergen Biosystems Inc., which made the equipment used in the Lancet study,
said that the machines were reliable and that his company had stopped working
with Correlogic Systems because "we don't have confidence in that approach."
Ciphergen Biosystems, which is based in Fremont, Calif., hopes to introduce its
own ovarian cancer test, based on three known proteins, by the end of this
year, Dr. Rich said. Developers of OvaCheck said that though different machines
and sample preparation techniques resulted in different patterns, the computer
could figure out how to discriminate cancer from noncancer. They retested the
Lancet samples with different equipment and got the same good results, they
said. With a larger sample, they had 100 percent accuracy, with no false
positives. So as long as Quest Diagnostics and LabCorp are consistent in how
they process samples, they should get good results, they said. And others have
shown the approach works. Dr. O. John Semmes, an associate professor at Eastern
Virginia Medical School, is using protein patterns to develop a prostate cancer
diagnostic. He said his group had found that multiple labs got the same results
when they ran the same set of samples. Still, he said, more extensive
validation is needed and is under way. OvaCheck's developers plan to conduct a
clinical trial to win F.D.A approval for diagnosing recurrences of ovarian
cancer. A trial for approval as an early-stage diagnostic tool would take too
long, they said. Dr. Petricoin says that even if the test is not perfect, it is
"blowing away what's being used now," like the CA-125 test. "You have women
right now that are getting prophylactic oophorectomies based on CA-125," he
said, referring to the surgical removal of ovaries to prevent cancer. For that
reason, some doctors think the test will be in great demand from anxious women
who view ovarian cancer as a death sentence. "Before you mass-market to the
uninformed, fearful population, it should be peer-reviewed," said Dr. Karlan of
Cedars-Sinai. But when asked whether she would recommend her patients not get
tested, she said: "It doesn't matter what I recommend. They are going to do it
anyway."
