TORONTO, April 27 /CNW/ - A new Canadian Cancer Society-funded study
will investigate the genetic puzzle of a devastating nervous system
cancer that strikes infants, and identify potential new treatments for
the disease. The study is one of 52 new research projects worth more
than $21 million announced today by the Society. The projects cover a
broad spectrum of cancer research from risk reduction to genetic
studies to drug development and palliative care.
"With these new projects, the Canadian Cancer Society continues to
support a vibrant research community that is seeking ways to reduce
cancer risk, reduce cancer deaths and improve the quality of life of
those living with cancer," says Dr Christine Williams, Director of
Research, Canadian Cancer Society Research Institute. "We're making
this announcement on our first nationwide Daffodil Day to underscore
the importance of research in the fight against cancer and to remember
those people who are on a cancer journey. We encourage Canadians to
join us by wearing our new daffodil pin."
Putting together the pieces of the neuroblastoma puzzle
With a grant of $430,302, Dr Meredith Irwin, a researcher and clinician
at The Hospital for Sick Children (SickKids), is leading the
neuroblastoma study. This cancer of the nervous system, which causes
tumours in the spinal cord, abdomen, chest and adrenal glands, is one
of the most common childhood cancers and also one of the most frequent
causes of childhood cancer death.
In her dual role as a scientist working in the lab and a doctor caring
for these young patients and their families, Dr Irwin brings a unique
"I feel like I'm fighting the disease in two ways - I'm helping families
through a tremendously difficult time with treatment and support, and
I'm trying to make a difference in how we understand neuroblastoma and
how we can make an impact on this disease," Dr Irwin says.
There is another reason for Dr Irwin's curiosity about this disease -
her own cancer journey. "My experience makes me want to answer those
basic biology questions - to know what makes cancer cells tick - so we
can understand the cancers our patients are fighting and what types of
treatment they need."
Dr Irwin and her research team will use two approaches to better
understand and potentially treat neuroblastoma:
They will study the various genes and proteins involved in killing
neuroblastoma cells and try to determine how to activate these "death
They will also study neuroblastoma cells that have spread to the bone
marrow and try to understand how they are different from other
neuroblastoma tumour cells that have spread to other locations in the
body. Using this information, they will test drugs already used in
other diseases to see if they can specifically kill neuroblastoma cells
in the bone marrow, the most frequent site to which the disease
"Ultimately, what I want to do as a clinician-scientist is to be able to
have a different conversation with children and their parents about a
neuroblastoma diagnosis. If the results of our research allow me to say
to some patients that we can successfully fight the disease once it
comes back, that would be the best thing in my career."

A survivor's story: Leanne Waddell
Leanne Waddell was only 10 months old when she was diagnosed with
Today, more than 30 years later, Leanne knows how fortunate she is to be
a survivor and to be able to help others going through a cancer
"Fighting cancer has always been a mission of mine; it's something I've
always felt strongly about," Waddell says.
It was Waddell's babysitter who noticed one evening that the baby girl
had difficulty breathing when she was lying down, but when she sat up
she was fine. When Waddell's parents rushed her to the hospital, the
doctors found a massive tumour - about the size of a man's fist -
wrapped around her small spinal cord.
Surgery followed by radiation treatment left Waddell disease-free but
her doctors had warned her parents she would never be able to walk
because of the damage to her spine. Waddell proved them wrong.
And so began her personal fight against cancer. She started volunteering
with the Society as a child, selling daffodils with her mom, and
continued volunteering well into her adult years. Just two months ago
she became the manager of a Canadian Cancer Society unit office. She
also spends time with neuroblastoma patients and their families,
showing her first-hand the many ways this disease can affect children.
She says research projects like Dr Meredith Irwin's are vital in
advancing our understanding of neuroblastoma. "We know it can be a
deadly disease and it's especially devastating when it relapses. It's
important we try to find it and treat it early so maybe it doesn't get
to that point."
The effectiveness of treatments for neuroblastoma can also vary. Not all
young patients respond to current treatments, which is why more
research is needed. "Research is the only way we will find better
treatments that will help more children."
"My experience fuels my drive. I constantly do my best to make an impact
against this disease, especially fundraising for research. Even if it's
a small difference, it's still a difference."
Highlights of other new Canadian Cancer Society research projects
The Society's long-term goals are to deter, defeat and defy cancer, and
research is a vital part of achieving these goals. The following are
just a few examples of the new research projects we are funding which
will help support Canadians fighting cancer throughout all stages of
their cancer journey.
Dr Angela Cheung, Toronto, $632,192 - Dr Cheung is studying the long-term effects of the drug exemestane on
bone health as part of a large clinical trial testing whether the drug
is effective at preventing breast cancer in post-menopausal women at
increased risk for the disease. Exemestane is in a class of
medications that may have negative effects on bone health, and this
study will provide crucial information about the long-term safety of
the drug and the risks and benefits for this group of women.
Dr Shelley Harris, Toronto, $846,000 - Brominated flame retardants are an emerging group of pollutants
showing up with increasing frequency in the environment. Using blood
and urine samples of women aged 18 to 44 - some who have cancer and
some who do not - Dr Harris will investigate whether increased exposure
to one type of brominated flame retardants, specifically polybrominated
diphenyl ethers (PBDEs), is associated with increased breast cancer
Dr Raymond Andersen, Vancouver, $420,527 - Many of the most effective anti-cancer drugs have come from nature,
and Dr Andersen's study looks to the world's oceans as a resource for
naturally occurring anti-cancer substances. The goal of this project is
to discover organic compounds that are present in marine invertebrates
and micro-organisms to develop new drug treatments for cancer, with a
particular focus on advanced stage prostate cancer.
Dr John Dick, Toronto, $432,000 - Dr Dick's lab was the first to discover leukemia stem cells (LSCs)
and is now working to identify genes and other molecular elements that
determine how blood cells get programmed into LSCs. Using large-scale
tests in human blood samples, the research team will induce leukemia by
manipulating the MLL gene and characterize the biological effects that
lead to the development of LSCs and leukemia.
Dr Aaron Marshall, Winnipeg, $418,977 - Dr Marshall's team is focused on understanding molecular processes
that lead to poorer patient outcomes by helping leukemia cells move out
of the blood and into bone marrow and lymph nodes. In this study, they
will focus on components in a molecular pathway called PI3K that help
leukemia cells "team up" with other cells to proliferate and spread, to
identify which patients might benefit most from chemotherapy that
targets this process.
Dr Hanne Ostergaard, Edmonton, $432,000 - Some cancer drugs currently in clinical trials block the function of
a protein called Pyk2 that helps cancer cells move, but Dr Ostergaard's
team believes this protein also helps the body's natural killer cells
fight cancer. This study will advance the understanding of Pyk2 and
another protein called paxillin to help determine how to prevent cancer
cells from metastasizing and promote killer cell function.
Dr Maru Barrera, Toronto, $566,969 - After overcoming the hurdle of childhood brain cancer, some young
survivors face the additional challenge of weakened social skills due
to injury to the brain. Dr Barrera's team will evaluate the impact of a
new program that helps to remediate social skills deficits - a program
with the potential to improve these children's abilities to manage
relationships at home and at school.
Dr Ari-Nareg Meguerditchian, Montreal, $124,639 - Taking a daily anti-estrogen pill has significantly improved breast
cancer survival rates, but many patients discontinue the treatment
prematurely, particularly women 65 and older. Dr Meguerditchian's study
will use Quebec's drug insurance databases to determine how many women
in this age group took anti-estrogen pills between 1998 and 2005 and
predict who is at highest risk of stopping the therapy before the end
of the five-year treatment in order to better support this group of
