TELOMERES REVEAL MELANOMA SECRETS
It’s a pleasure to bring you up to date with
our work in the Genetic Epidemiology
of Melanoma study. Since the 1980s we
have been working together with people
who have a family history of melanoma.
Since the year 2000, thousands more
people joined our study of melanoma
in the community – the Australian
Melanoma Family Study.
Both these projects run concurrently
now, with the aim of fully understanding
the ways that genes affect our risk of
developing melanoma. We work towards
this goal in tandem with studies based
in Queensland – the Q-MEGA project,
so that information from people with
melanoma around Australia and New
Zealand can be pulled together in the
most effective way.
out. So we have special mechanisms to
keep them at the right length. Cancer
cells learn how to misuse them so they
can keep growing – without this they
would age and die like normal cells.
it is not clear how much extra risk is
produced and the number of families
with these mutations seems to be quite
small, we intend to clarify this over the
coming year.
2014 has brought more progress in
understanding the melanoma puzzle. In
every cell, telomeres are the fragile ends
of our chromosomes, the big bundles
of DNA in which our genes are grouped.
Telomeres are hard to replace each
time a cell divides, and they can wear
Shelterin proteins (See Figure) are part
of these protections and telomerase is
the protein that does the repair work. In
the past year we and others have shown
that some melanoma families have
inherited a faulty version of the shelterin
genes POT1, ACD or TERF2IP [1,2]. While
And this is part of a bigger picture.
Everyone varies a little in how long
their telomeres are. We have recently
shown that this tendency is connected
to melanoma risk, for the first time in
any cancer [3]. So telomeres have a lot
to teach us about melanoma!

NEW BUILDING
Melanoma research at the Westmead Millennium
Institute has been given a boost with the official
opening of the institute’s new building in October.
The nine-storey complex includes new melanoma
research facilities funded by $7 million in grants
awarded by the Australian Cancer Research
Foundation (ACRF). Located on Level 7 in the Centre for Cancer
Research, the ACRF Melanoma Research
Laboratories provide state-of-the-art facilities
for melanoma research. The melanoma program
investigates all its aspects, from risk in families to
developing better diagnostic tests and treatments.
The new building brings all of WMI’s 11 centres of
research - which were previously scattered across
six locations on the Westmead Hospital campus together under one roof for the first time.
According to WMI Executive Director, Professor
Tony Cunningham, the building creates efficiencies
and new opportunities for trans-disciplinary
research collaboration.
“The building encourages interaction and the
exchange of knowledge and ideas between
researchers who were previously physically
isolated from one another,” said Professor
Cunningham. “This is enhancing collaborations
across disciplines and I believe it will lead to some
significant research advances.”
In June the Genetic Epidemiology of Melanoma
project team relocated to the Centre for Cancer
Research.* “For the first time we have our entire
melanoma team in one place,” said Professor
Graham Mann. “This has already made every
aspect of our work easier, and we can now
really take advantage of the excellent research
environment in WMI.” *Formerly the Westmead Institute for Cancer Research
THE MELANOMA HIGH
RISK CLINIC
Melanoma High Risk Clinics (HRC) have been
established under Cancer Institute NSW (CINSW)
Translational Research Program funding to trial a
program of computer-assisted photographic monitoring
that aims to detect melanoma efficiently at an early
stage. Clinics are currently operating at Royal Prince
Alfred Hospital, Melanoma Institute Australia, Newcastle
Skin Check and recently opened at Westmead Hospital.
These research clinics are free to attend but places are
restricted to those who have:
• had two or more invasive melanomas
• had at least one invasive melanoma as well as
Dysplastic Naevus Syndrome
• had at least one invasive melanoma as well as three
or more relatives who have had melanoma
• been diagnosed as carrying a family mutation in a
known melanoma gene, whether or not they have
had melanoma (NB they must have attended a family
cancer clinic or genetic counsellor and have had
clinical genetic testing).
A major report on our first five years experience was
published earlier this year: Moloney, F., et al., Detection
of primary melanoma in individuals at extreme high
risk: a prospective five-year follow-up study. JAMA
Dermatology 150(8):819-27 (2014)

Risk Clinic please call Helen Schmid on 02 8627 3786

SOLARIUMS BAN UPDATE
Research results from the Australian Melanoma Family
Study were a key reason for this government action. In
2011 we showed for the first time that solarium use was
a cause of melanoma in Australia.
Furthermore, the increased risk was strongest in young
people. Among solarium users we estimated that about
three quarters of the melanomas occurring before the
age of 30 were due to sunbed exposure.
By January 2015 bans on sunbeds will have come
into effect in New South Wales, Queensland, Victoria,
Tasmania and the Australian Capital Territory. Western
Australia and the Northern Territory are currently
debating this issue.
UV AND NAIL VARNISH
There has been concern about the UV exposure
to fingers when curing nail varnish in nail salons.
Evidence about the safety of the practice is lacking at
the moment, although the UV used is similar to that in
solariums, the total dose received by the fingers is quite
small. A recent letter in JAMA Dermatology 150 (7), 2014
expressed the situation well:
“Although the in vivo risk from multiple manicure
visits remains untested, our data suggest that, even
with numerous exposures, the risk for carcinogenesis
remains small. That said, we concur with previous
authors in recommending use of physical blocking
sunscreens or UV-A protective gloves to limit the risk
of carcinogenesis and photoaging.”

CHECKING YOUR SKIN
Checking your skin regularly for melanoma is essential
for early detection and can be lifesaving. Here is a
useful guide:

LIFE INSURANCE AND
OUR RESEARCH
In Australia, the life insurance industry has agreed that
it will not require people to have DNA tests before
taking out life insurance. However, if individuals have
had DNA tests, they must report the results in their life
insurance application.
DNA results from research projects only have to be
declared to insurers if the participant in the project is
informed about their individual results.
