Skin reactions during radiation therapy preventable: new finding
Severe skin reactions during
radiation therapy could be prevented by applying a thin
transparent silicone dressing to the skin from the first day
of treatment, a clinical trial shows.
Although many
skincare products have been tested in clinical trials over
the years, until now none have been able to completely
prevent severe skin reactions, says senior lecturer Dr
Patries Herst of University of Otago Wellington’s
Department of Radiation Therapy.
Dr Herst and her team
of radiation therapists, oncology nurses and medical
physicists have completed five randomised controlled
clinical trials in public hospitals in Dunedin, Wellington,
Palmerston North and Auckland Radiation Oncology over the
past five years, all focusing on side effects caused by
radiation therapy.
Their most recent trial was a close
collaboration with Dunedin Hospital, and demonstrated it is
possible to prevent skin reactions from developing in breast
cancer patients undergoing radiation therapy.
Skin
reactions are common in these patients, ranging from mild
redness to ulceration with symptoms of pain, burning and
itchiness, Dr Herst says.
“This can impact
negatively on day-to-day life for patients who already have
to cope with being diagnosed with and treated for
cancer.”
She is delighted with the results, and
identification of a product that really works.
“This
is fantastic news for cancer patients and it has put New
Zealand firmly on the world map as a leader in clinical
research into radiation-induced acute side
effects.”
The dressings work by adhering closely to
the small folds in the skin without the use of adhesives, so
do not stick to open wounds. By protecting the
radiation-damaged skin from friction against items of
clothing or other parts of the body, they allow the stem
cells of the skin to heal from the radiation damage in an
undisturbed environment. The dressings are also free of
chemicals that could react with the skin.
Dr Herst is
currently setting up a trial that will test the dressings in
head and neck cancer patients.
The results have been
published online in the international journal
Radiotherapy and
Oncology.
