Australian Associate Professor Guy Hingston confirms that MINDACT proves that less Australian women will now need chemotherapy for breast cancer
Late last week, the investigators of the large international MINDACT (Microarray in Node Negative and 1-3 Positive Lymph Node Disease May Avoid Chemotherapy) Trial, published in the New England Journal of Medicine, proved that potentially 46% of women with clinically high risk oestrogen positive HER2 negative early breast cancer with up to three lymph nodes involved, may receive no benefit from chemotherapy if they return a low risk 70 gene signature (MammaPrint) genomic result.
According to Associate Professor Hingston, he believes that this is the best news in breast cancer management in 2016. “As of late last week, the world of breast cancer treatment has undergone another paradigm shift. We should now manage women with breast cancer differently, by incorporating the 70 gene MammaPrint signature testing in all women who are being considered for chemotherapy – if they have T1c or T2 oestrogen receptor positive HER2 negative disease with up to three nodes involved. We now have Level 1A data confirming the significant clinical utility of MammaPrint testing, and therefore we should all now routinely use this test on the approximately 4,000 Australian women who each year develop this type of breast cancer.”
He is not alone in this view. Dr Clifford Hudis, the current Chief Executive Officer of the American Society of Clinical Oncology (ASCO) has stated in an accompanying editorial in last week’s New England Journal of Medicine that “On the basis of the MINDACT study, clinicians may consider ordering the 70-gene signature for patients in line for chemotherapy who hope to forgo it on the basis of a possibly low genomic risk.”
Associate Professor Hingston is now calling on all medical oncologists to consider using MammaPrint due to the publication of the Level 1A data late last week confirming that the envisaged benefit of chemotherapy in a selected subgroup of Australian women with breast cancer may not actually be present. MammaPrint testing could potentially benefit around 2,000 Australian women each year, preventing them needlessly suffering the risks of chemotherapy – namely long term cardiotoxicity, secondary leukemia, impairment in cognitive function and neurotoxicity.
Further, he is renewing his call to the Australian Government Department of Health Medical Services Advisory Committee, asking that MammaPrint be funded in full by the Government. “MINDACT has now clearly shown that MammaPrint is both prognostic and predictive, and Australian women should join women from all over the world who are now benefitting from this new genomic microarray technology. Approximately 2,000 Australian women each year could benefit from MammaPrint testing, and they should not undergo the harms of chemotherapy if there is no significant benefit to this treatment, just because they can not afford this new test”. The price of MammaPrint has been stable at $USD4,200 for the last several years.
Associate Professor Hingston introduced fixed formalin paraffin embedded (FFPE) MammaPrint testing into Australia in late 2013, and he has personally seen the benefits of this genomic test on many of his own patients. A small part of the breast cancer (either one core of the preoperative core biopsy or a small piece of the surgically resected tumour) is sent overseas to the MammaPrint laboratory located in Los Angeles for testing. There is a 12 – 14 day turn around, and the result is returned as either low risk or high risk. Testing is ordered online by medical or surgical oncologists looking after women with a new diagnosis of early breast cancer.
The 70 gene signature MammaPrint microarray test was initially developed in Holland by Dr Laura Van’t Veer on a sample group of 100 women who had breast cancer. She first published her findings in Nature back in 2002. Since then, MammaPrint testing has been approved by the FDA, and has now been proven in many large retrospective studies. However, MammaPrint is now the first genomic test to provide Level 1A prospective randomized data from a large Phase 3 trial of women with an early diagnosis of breast cancer who have been followed for five years. MINDACT tested MammaPrint on 6,693 women from 111 medical centres from 9 European countries. No other genomic test has yet provided Level 1A prospective randomized data to support its use in clinical practice.
The authors of the MINDACT publication state that “The primary goal of MINDACT was to assess whether, among patients with high-risk clinical features and a low-risk gene expression profile who did not receive chemotherapy, the lower boundary of the 95% confidence interval, for the rate of 5-year survival without distant metastasis would be 92% (i.e. the noninferiority boundary) or higher.”
The MINDACT results have shown that out of 1,550 women who were allocated to the high clinical risk:low genomic risk subgroup, that the rate of survival without distant metastasis was 94.7% (95% confidence interval, 92.5 to 96.2) among those not receiving chemotherapy. The authors of MINDACT therefore conclude that “Given these findings, approximately 46% of women with breast cancer who are at high clinical risk might not require chemotherapy” if they return a low genomic risk MammaPrint result.
MINDACT has now confirmed beyond any reasonable doubt that MammaPrint genomic testing represents a new paradigm shift in modern breast cancer management. Dr Bernard Fisher published back in 2002 the National Surgical Adjuvant Breast and Bowel Project (NSABP) 25 year follow up data confirming that partial mastectomy and radiotherapy had the same long term survival rates as mastectomy. This was the first major paradigm shift in modern breast cancer management, and sentinel node biopsy has now been accepted as being the second significant paradigm shift, replacing axillary clearance in the majority of women with breast cancer. Associate Professor Hingston now states that MammaPrint testing, as shown by the Level 1A prospective randomized MINDACT data, is being recognized as being the next significant paradigm shift in modern breast cancer management, and clinicians the world over are now embracing this MammaPrint technology on behalf of their patients.
Associate Professor Guy Hingston is a surgical oncologist with nearly 20 years experience in the oncoplastic management of women with breast cancer. He resides in Port Macquarie providing comprehensive breast cancer surgical service in a private capacity to women from northern New South Wales. He is currently setting up a breast cancer genomic study through the University of Newcastle’s Hunter Medical Research Institute, using next generation sequencing and droplet digital polymerase chain reaction equipment to individually characterise mutations in breast cancer, and he is hoping to shortly commence measurement of circulating tumour DNA in women with breast cancer. He is a new breed of oncoplastic breast cancer surgeon who believes that modern genomic assessment (like MammaPrint) is now part of the future management of all women who develop breast cancer. He is also currently the surgical oncology representative on the TransTasman Radiation Oncology Group Scientific Trials Independent Data Safety & Monitoring Committee.
Breast cancer patients could be spared chemotherapy with new genetic test, study shows
by Kate Aubusson, The Sydney Morning Herald
It’s a gruelling decision every breast cancer patient and their doctor must consider: do we need to start chemotherapy, or could we spare you the ravages of the toxic, yet potentially life-saving treatment?
A genetic test could see thousands of Australian women with early-stage breast cancer safely avoid chemotherapy, a landmark trial shows.
Based the genetic profile of their tumours, nearly half of women (46 per cent) with early-stage breast cancer who are at high clinical risk of the cancer returning may not require chemo, found one of the largest and most robust studies of genetic testing published.
The trial investigated whether the test (dubbed MammaPrint in Europe and Australia) could identify which patients had a low genetic risk of their cancer re-emerging among women in the early stages of the most common type of breast cancer: HER2 negative tumours.
Researchers screened more than 6600 patients and found 1550 had a high clinical risk, but low genetic risk, of their cancer returning.
Women deemed to have a high clinical risk of recurrence are usually treated with chemo.
The researchers randomly assigned these women to chemo treatment or no chemo after their first-line treatments (surgery, hormone therapy and radiation).
After five years, 94.4 per cent of the women who did not receive chemo had no distant metastasis; their cancer hadn’t spread, found the study published in the New England Journal of Medicine on Thursday.
There was only 1.5 percentage points that separated them from the women who did receive chemo, with 95.9 per cent of these patients showing no distant metastasis at the five-year mark.
“We found that chemotherapy with its toxic effects could be avoided in these patients,” the authors concluded. They plan to follow the women for another five years to document their ongoing survival rates.
“Given these findings, approximately 46 per cent of women with breast cancer who are at high clinical risk might not require chemotherapy, they said.
The risks from certain types of chemo increase with the patient’s age. The risk of leukemia is about 0.5 per cent to 1 per cent, and the heart risk can reach 4 per cent or 5 per cent in older women, Dr Freedman said.
Australian oncologist Associate Professor Guy Hingston – who pioneered access to MammaPrint for Australian women – recommended all Australian women who were about to undergo chemo should check with their oncologist to see if they would benefit from the test.
Between 4000 and 5000 Australian women diagnosed with breast cancer every year would be eligible for the test. The study results suggest roughly 2000 to 2500 women could be spared chemo every year.
“We now live and work in a different world of breast cancer management. Women already shattered with a new diagnosis of breast cancer, should not needlessly be put through chemotherapy, if genomically their cancer can be shown to have a low risk of recurrence,” Associate Professor Hingston said.
“As a medical profession, we are here to help women, not hurt them, and this form of genomic testing is a great step forward in our ability to more accurately target treatment and provide personalised cancer therapy.”
But MammaPrint is not universally accessible. Australian samples are sent to Los Angeles for testing and come with an out of pocket cost of roughly $5500 in Australia.
The medical services advisory committee is assessing an application for government funding.
A sobering editorial published alongside the study findings warned the trial was not the final proof that chemotherapy could be tossed aside for this group of patients.
“The immediate question for many observers is this: Was withholding chemotherapy in such patients actually safe?” wrote Drs Clifford Hudis and Maura Dickler at the Memorial Sloan Kettering Cancer Center, New York.
“[A] difference of 1.5 percentage points, if real, might mean more to one patient than to another.
“What doctors and their patients do with the results of such testing will be highly individualised — and will inevitably be finessed by the findings from future studies,” they wrote.
Targeted Breast Cancer Medical Treatment Now A Reality – MINDACT is Out!
Dr Martine Piccart and her colleagues have today published in the New England Journal of Medicine their results of the landmark international prospective randomized Microarray In Node negative Disease May Avoid Chemotherapy (MINDACT) study. MINDACT assessed MammaPrint genomic testing of nearly 7,000 women with early breast cancer. In Australia, Associate Professor Guy Hingston says that this is the biggest news in breast cancer management in 2016!
Going against the prevailing Australian view at the time, Associate Professor Guy Hingston commenced using this modern international genomic test in northern NSW in 2014, and published his initial MammaPrint results back then in the Asia Pacific Journal of Oncology. However, with the publication of MINDACT today, Associate Professor Guy Hingston considers that MammaPrint is now set to become the international standard of care in genomic testing in breast cancer. “MammaPrint testing has now been shown to be the most reliable international testing platform for the genomic assessment (of approximately one third) of women who present with a new diagnosis of early breast cancer. This means that each year in Australia, around 5,000 Australian women could benefit from this new technology.”
“MammaPrint is the first genomic test in early breast cancer that has been shown through a prospective randomised international five year follow up cohort of nearly 7,000 women to be both prognostic and predictive.” As of today, Associate Professor Guy Hingston recommends that all Australian women who are about to undergo chemotherapy for early breast cancer should now check with their medical oncologist to see if they could benefit from MammaPrint testing. He has made this bold statement because MINDACT has shown that there is a 46% reduction in the need for adjuvant chemotherapy in the subgroup of women who have hormone positive breast cancers between 20mm and 50mm in diameter, including those with node negative or node positive disease (with up to three nodes involved).
According to Associate Professor Guy Hingston, MINDACT has shown that there is no advantage for undergoing chemotherapy if the MammaPrint genomic test returns a low risk result, as the large group of women in MINDACT randomized to receive or not receive chemotherapy obtained no statistically significant benefit in terms of 5 year distant metastasis free survival or overall survival. Therefore, Associate Professor Guy Hingston asks why women should needlessly undergo all of the side effects, and run the risk of major complications of having chemotherapy, if no benefit is to be obtained? More information about MINDACT and MammaPrint testing can be obtained online at www.mammaprint.com.au.
Back in late 2013, and to help Australian women access this new technology, Associate Professor Guy Hingston set up a company called Genome Investigation Pty Ltd which now assists Australian women to obtain this form of breast cancer testing. Genome Investigation also commenced an application for public funding of MammaPrint through the Australian Government Department of Health Medical Services Advisory Committee. While this application remains afloat, it is Associate Professor Guy Hingston’s view that today’s publication of MINDACT means that the Department of Health should now immediately commence funding of MammaPrint testing for those women who are eligible, after appropriate referral from a specialist oncologist.
“As of today, and because of MammaPrint testing proven through MINDACT, we now live and work in a different world of breast cancer management. Women already shattered with a new diagnosis of breast cancer, should not needlessly be put through chemotherapy, if genomically their cancer can be shown to have a low risk of recurrence. As a medical profession, we are here to help women, not hurt them, and this form of genomic testing is a great step forward in our ability to more accurately target treatment and provide personalized cancer therapy.”
Further, Associate Professor Guy Hingston states that we are now heading into an exciting era of breast cancer management, where over-treatment is being replaced with targeted treatment. Surgical oncologists initially lead the way with partial mastectomy (avoiding mastectomy), and then sentinel node biopsy (avoiding unnecessary axillary clearance). However, proven MammaPrint genomic testing is now leading the way with more personalized targeted medical treatment options, and this is great news for all those involved in breast cancer management, both patients and clinicians alike.”
Associate Professor Guy Hingston is an expert in the clinical management of breast cancer, with nearly 20 years of clinical experience as a specialist surgical oncologist. He currently resides in Port Macquarie, where he maintains a private practice in oncoplastic breast care. However, he is currently trying to establish a significant breast cancer research project through the Hunter Medical Research Institute, and is focused on establishing the genomic basis of breast cancer using next generation sequencing technology looking for the underlying somatic breast cancer mutations. He sees this as the next important practical step which is needed to help women with a new diagnosis of breast cancer.

70-Gene Signature Identifies Breast Cancer Subgroup Unlikely to Benefit From Adjuvant Chemo
Article by Wayne Kuznar
A 70-gene signature (MammaPrint) demonstrated a high level of accuracy at identifying a large subset of women with clinically high-risk early stage breast cancer for whom adjuvant chemotherapy was unlikely to produce benefit, according to findings from a phase III trial presented at the AACR Annual Meeting 2016.
In the study known as MINDACT, patients deemed high risk clinically but low risk by the gene signature had a similar 5-year rate of distant metastasis-free survival (DMFS) whether randomized to adjuvant chemotherapy or not, said Martine Piccart, MD, PhD. “The important message here is among the clinically high-risk patients, the clinical use of MammaPrint is associated with almost a halving of the use of chemotherapy,” she said
The rate of 5-year DFMS in women who were clinically high risk/genomically low risk and randomized to no chemotherapy was the primary statistical test for MINDACT. In this group, in which 48% of the women had positive nodes, the 5-year DMFS was 94.7% (95% CI, 92.5%-96.2%), which passed the bar for significance of 92%.
Overtreatment with adjuvant therapies, especially chemotherapy, is common for patients with breast cancer, in an attempt to eradicate micrometastases. In this setting, overtreatment is considered adjuvant chemotherapy that is associated with a small survival benefit, in the range of 2%, while exposing the patient to long-term risks such as secondary cancers, secondary leukemia, and congestive heart failure, said Piccart, Head, Department of Medicine, Jules Bordet Institute in Brussels, Belgium, and Co-Founder and Chair of the Breast International Group.
The MINDACT trial was opened in 2007 and originally included women with negative nodes, but was amended in 2009 to enroll women with one to three positive nodes. “Essentially, we got very confident that the genomic assay would outperform the clinical criteria by reducing the prescription of adjuvant chemotherapy without impairing patient outcome,” said Piccart. As such, MINDACT is the only clinical trial pitting tumor biology against tumor anatomy with a few biological features added, she said.
MINDACT enrolled 6693 patients with early breast cancer from 112 centers in nine European countries who had their risk of tumor recurrence following surgery assessed in two ways: through use of MammaPrint, performed on frozen tumor tissue, and also via Adjuvant! Online. Overall, 2745 women were categorized as low risk using both methods, 1806 were categorized as having high risk of recurrence by both methods, 592 were categorized as high risk of recurrence by MammaPrint and low risk of recurrence by Adjuvant! Online, and 1550 were categorized as low risk of recurrence by MammaPrint and high risk of recurrence by Adjuvant! Online.
Patients characterized by both assessments as low risk were spared adjuvant chemotherapy while chemotherapy was advised for those characterized as high risk by both methods. Those with discordant results were randomized to adjuvant chemotherapy or no adjuvant chemotherapy.
Altogether, 88% of the patients enrolled had hormone receptor (HR)-positive tumors and 10% had biologically aggressive HER2-positive disease. After a median follow-up of 5 years, 3% of the study population died and 5.4% experienced either distant metastases or death.
Five-year DMFS was 97.6% among the women who were low risk by both assessment methods. In contrast, DMFS was 90.6% among the women who were high risk by both methods and received adjuvant chemotherapy. “The low-risk patients were mostly node-negative [with] small tumors with hormone receptors,” said Piccart. The high-risk patients had larger tumors, were node-positive in 25% of the cases, and triple-negative in about one third of cases, she added.
The “discordant” groups, meaning low by one measure and high by another, had a rate of DMFS in between that of the “concordant” groups (low-low and high-high). The 5-year DMFS rates were 94.8% and 95.1% in the patients who were clinically low risk/genomically high risk and clinically high risk/genomically low risk, respectively.
The trial was not powered to detect a clinical benefit to chemotherapy in discordant risk groups, she explained, but on intent-to-treat analysis, a 22% relative reduction in the risk of 5-year DMFS with chemotherapy was observed “which would translate into a very small absolute benefit that would not justify the risks of chemotherapy,” she said.
Among the entire MINDACT population, using a clinical strategy to assign chemotherapy would result in 50% of patients receiving chemotherapy, compared with only 36% using the genomic strategy, for an absolute reduction of 14% in chemotherapy prescription, Piccart noted.
“MINDACT provides level 1A evidence of the clinical utility of MammaPrint,” she concluded. This is the highest level of evidence shown to date for a risk assessment tool for determining whether chemotherapy should be used.
Because nearly all ER-negative or HER2-postive tumors would be expected to rate as both clinically and genomically high risk, MammaPrint and the MINDACT results bear mostly on the heterogeneity within ER-positive, HER2-negative cancers, commented Harold Burstein, MD, PhD, clinical oncologist at Dana-Farber Cancer Institute, Boston.
The study “confirms the primary hypothesis that integration of genomic signature permits identification of a cohort of ER-positive tumors with good prognosis with endocrine therapy alone, regardless of larger T stage and N1 status,” he said, advocating that most ER-positive, HER2-negative stage 1 and 2 cancers, including N1, warrant tumor genomic profiling for optimal adjuvant decision-making.
New Agreed Prostate Cancer Screening Guidelines
The Prostate Cancer Foundation of Australia (PCFA) and the Cancer Council Australia gathered all the disciplines involved in testing – urologists, pathologists, epidemiologists, GPs, radiation oncologists, medical oncologists and allied health professionals – and produced consensus guidelines.
It took three years, it cost $1 million (although experts gave their time gratis) and its recommendations have now been approved by Australia’s highest scientific body, the National Health and Medical Research Council.
Called PSA Testing and the Early Management of Test-detected Prostate Cancer, it is intended for general practitioners, working with middle-aged and older men who have no symptoms of prostate cancer but are considering having a blood test for the cancer.
The PSA test measures for a protein called prostate specific antigen in the blood which is an unreliable marker for cancer but the best we have.
Prostate cancer is the second-most important cause of cancer death in Australian men and these guidelines should give them the confidence to go to their GP and discuss the benefits and harms of testing before making a decision.
Some of the old rules of thumb have changed. It’s known that any mortality benefit from early diagnosis of prostate cancer due to PSA testing is not seen within the first six or seven years following testing.For this reason, the guidelines recommend no PSA testing for men, with other health issues who are unlikely to live another seven years.
The guidelines also say harms of testing – it can lead to unnecessary treatment which can, in turn, lead to urinary incontinence, erectile dysfunction and bowel problems – may outweigh benefits.
The area is complex but their simple message is that Australian men at average risk of prostate cancer who decide to have regular testing should be offered PSA test every two years from the ages of 50 to 69.
If, on this test, their PSA is greater than 3 nanograms per millilitre.
The recommendation is different for those with a family history of prostate cancer who may be at higher risk and should be offered testing every two years from the age of 40 or 45 depending on the strength of the history.
The removal of the standard rectal examination conducted by GPs on men without symptoms will be widely welcome.
One third of cancers are preventable, Queensland research finds
Landmark Queensland research has found almost a third of cancers could be prevented by simple lifestyle changes.
Researchers found that 37,000 cancers were preventable, following research of 13 known cancer risk factors, including smoking, diet, obesity and UV light exposure.
The QIMR Berghofer Medical Research Institute study, funded by Cancer Council Australia, used statistics analysis to track just how many cancers were caused by each risk factor.
Smoking was by far the leading cause but lead author Professor David Whiteman and his team found 7000 new cancer cases were attributable to low fruit and vegetable intake, low fibre intake and eating excess red meat.
The epidemiologist said it meant if people followed the cancer council’s lifestyle guidelines they could reduce their cancer risk by a third.
“There are many benefits from following the guidelines and the advice but reducing the cancer risk is one of them,” he said.
“And having 37,000 fewer people each year being diagnosed with cancer would make a huge economic impact each year for the country in days of working life lost, as well as just the direct treatment cost, financial and economic benefits.”
Alcohol caused 3200 incidences of cancer and not eating enough fruit was responsible for 1550 cases, the study found.
The researchers used a common statistical formula to work out how responsible each of the 13 risk factors was for each of 24 cancer types, which when combined with patient data helped to estimate the total number of cancers caused.
Many risk factors were linked to multiple cancer types.
The researchers found 32 per cent of cancers diagnosed in Australia in 2010 were attributable to the 13 risk factors, one percentage point higher in men and one lower in women.
It was the first time such a study had been done in Australia and one of the first applications of the technique in the world.
A look at cancer epidemiology in the UK a few years ago found a similar percentage were preventable but Professor Whiteman said the results were still striking.
“It’s quite sobering to realise that in an ideal world we could relieve 37,000 people each year of being given a diagnosis of cancer,” he said.
“Prevention takes a long time.
“It’s not a quick fix and prevention of cancer requires people to change their lifestyle but also requires government and society to recognise this is a priority and to encourage people to not take up these exposures.”
Cancer Council Australia CEO Professor Sanchia Aranda was hopeful the research would help more Australians avoid cancer.
“Of 13 identified risk factors, smoking, UV radiation, body weight, poor diet and alcohol caused around 90 per cent of all preventable cancers,” she said.
“It’s time to bust the myth that everything gives you cancer and do more to reduce the risks that we know cause cancer.”
The research was published in the Australian and New Zealand Journal of Public Health on Wednesday.
Calculate Your Risk Of Developing Breast Cancer
This user-friendly, interactive calculator is intended for use by women who have not had breast or ovarian cancer. It will help you to gain a good understanding of your level of risk for breast cancer compared to another woman of your age group. National Breast Cancer Centre* has based the questions in this calculator on the most important risk factors for breast cancer based on an up-to-date review of international evidence.
The calculator only takes a few minutes to complete, and the relevant risk factor is explained at each stage.
It is important to remember that the results of this calculator are not a guarantee of your risk levels, and that all women are at risk for breast cancer, no matter what their risk category. Some women at increased risk never develop breast cancer, and some women at low risk may develop the disease.
New form of intraoperative breast cancer radiotherapy
Intrabeam radiotherapy, which has go-ahead for NHS use, is given during surgery, eliminating need for additional hospital trips. Tens of thousands of breast cancer patients could benefit from a new type of radiotherapy which would be delivered during surgery instead of them having to take a course of treatment. Intrabeam radiotherapy has been given a provisional go-ahead for NHS use by the health finance watchdog. In draft guidance, the National Institute for Health and Care excellence (Nice) said the treatment option should be considered for people with early stage breast cancer. A single dose of radiotherapy could be more convenient for patients, Nice said. Some patients have to make 15 trips to hospital for radiotherapy, but the latest treatment could be given during breast surgery, reducing “disruption, stress and inconvenience”, the charity Breakthrough Breast Cancer said.
Those at risk avoid bowel cancer kits
Only a third of Australians who were sent a bowel cancer screening kit returned a sample for testing, despite the disease being the second greatest cause of cancer-related deaths.
The federal government sends a free kit to eligible Australians aged 50, 55, 60 and 65, but figures released by the Australian Institute of Health and Welfare on Monday showed only 33.5 per cent of these people sent back a faecal sample for laboratory analysis last financial year. Of those who returned a sample, 7.5 per cent required a follow-up visit with a medical practitioner.
Almost 4000 Australians died from bowel cancer in 2012, making it the second most common cause of cancer-related death after lung cancer. In the budget, the government committed $96 million to implement biennial bowel cancer screening for Australians aged 50 to 74 by 2020.
“About 80 Australians die each week from bowel cancer, despite the fact that, if it’s detected early, it’s one of the most treatable cancers there is,” Health Minister Peter Dutton said. “Test kits were sent to 964,000 people, and about 333,000 returned a sample. The participation rate in 2012-13 was slightly lower than in the previous year, when 35 per cent of people returned a sample.
Skin: Slip, slop, slap ads lower cancer rates
The melanoma rate is plummeting among the slip, slap, slop generation, according to an 18-year study of teenagers and young adults. It shows the effectiveness of the sun safety messages, research leader Professor Adele Green said.”It has been one of the most successful cancer prevention campaigns”, said Professor Green, whose team reviewed melanoma cases among 15 to 24 year olds in Queensland from 1982 to 2010. The success would be similar for the rest of Australia, said Professor Green, who has spent more than three decades studying skin cancer at the QIMR Berghofer Medical Research Institute in Queensland. Despite the fall, Queensland still has the highest rate of melanoma in the world. For people aged 20 to 24, the rate has fallen from 25 cases per 100,000 in 1996 to 14 per 100,000 in 2010.
Turning the Tide – Skin cancer rates fall for young Australian
Rates of non-melanoma skin cancer are finally dropping among younger Australians, according to a Queensland study. While the incidence of non-melanoma skin cancer continued to increase in older Australians during the period studied, the QIMR found the first recorded drop in Australians aged under 45 – down 1.5 per cent a year and more than 10 per cent over the decade – with even more rapid decreases in younger age groups. This is Great News for all working to prevent the unnecessary suffering caused by skin cancer. Dr Guy Hingston.
Obesity Spreading Worldwide
Almost a billion people in the developing world are now overweight or obese as they start to eat like people in the West. South Africa and Mexico have higher obesity rates than Britain, while rates have doubled in China in three decades, an analysis by the Overseas Development Institute has found. People in North Africa, the Middle East and Latin America are just as likely to be overweight as Europeans after an obesity explosion, says a study of statistics from the World Health Organisation and elsewhere. Rising incomes in poorer countries account for some of the change, but that does not mean governments could not do more to stem the rising ride of obesity. One in four adults in the developing world is now obese or overweight; numbers rose from 250 million in 1908 to 904 million in 2008.
Obesity now Cancer’s new best friend
Obesity has become the biggest preventable risk factor for cancer in Australia after smoking, experts have warned. A World Health Organisation report has confirmed the huge global toll from cancer, which is now the world’s biggest killer, responsible for 8.2 million deaths a year and rising. The World Cancer Report predicts that the number of cases will increase 75 per cent over the next two decades, topping 20 million new cases a year by 2025.
New breast cancer research regarding the Symphony® suite of genomic tests (MammaPrint®, BluePrint® and TargetPrint®)
New breast cancer research incorporating the Symphony® suite of genomic tests (MammaPrint®, BluePrint® and TargetPrint®) will be presented in 10 scientific posters at the upcoming 2013 San Antonio Breast Cancer Symposium (SABCS), Dec. 10-14.
“These ten studies further demonstrate Agendia’s continued commitment to providing the oncology community and their breast cancer patients with the most comprehensive and validated picture of tumor biology available in the market,” said Neil Barth, M.D., Agendia’s Chief Medical Officer.
Symphony is the only widely available test suite providing molecular subtyping — a recent advancement in breast cancer prognosis and treatment that is highlighted in several SABCS posters. The second-generation MammaPrint test provides definitive High Risk or Low Risk information about breast cancer recurrence, with no “intermediate” results.
Cancer Vaccination Victory
The HPV jab has halved the number of the precancerous lesions in young vaccinated Victorian women. Research shows that five years after the immunisation program started, the number of serious cervical abnormalities has fallen. Previous studies have shown a decrease in the prevalence of human papillomavirus in the population but Victorian Cytology Service (VCS) study director Professor Marion Saville said this was the first study to prove that the decline was due to vaccination. The study, published in the journal BMC Medicine, found that a population-based HPV vaccination program in schools significantly reduced cervical abnormalities for vaccinated women.
Too Busy for Breast Cancer Screening
One in two women are increasing their risk of breast cancer by skipping regular mammograms simply because they are too busy, according to alarming new research. Breast Screen NSW recently surveyed 1000 women aged 50-74 and found half missed their regular appointment, with most citing a “lack of time” as the reason despite 95 per cent agreeing the free screening could save their life. “Twelve women get diagnosed every day in NSW and 17 a week die of breast cancer, and many of these deaths don’t need to happen because screening can pick up a cancer as small as a grain of rice before it’s even able to be felt,” Cancer Institute of NSW deputy CEO Professor Sanchia Aranda said.
I consider breast cancer screening time well spent, particularly if it saves your life! Dr Guy Hingston.

Meter warns of sunburn risk
The Cancer Council WA wants public UV index meters installed in school playgrounds and at popular beaches, parks and sporting grounds to warn of sunburn and skin cancer risks.
Australia’s first public UV index meter, which measures solar radiation intensity every minute, was switched on at Deep Water Point in Mt Pleasant this week. The real-time UV index meter, which only recently became possible with new technology, would show when the UV level was above three – the level when people are advised to protect themselves from the sun.
Sounds like a good idea – to help people know how much radiation they are receiving from the big radiator in the sky.

Alcohol Consumption Before Pregnancy Increases Breast Cancer Risk
A paper, published today in the Journal of the National Cancer Institute, shows alcohol intake between a woman’s first period and her first pregnancy – when breast tissue is undergoing rapid growth – is associated with her likelihood of developing breast cancer.
Victorian Smoking Rates at All Time Low
Smoking rates in Victoria continue to fall with just 13 per cent of Victorians now smoking regularly and young people turning their back on the habit, new figures show. This means less people will have an early demise due to lung cancer, chronic airways disease, heart attack, stroke, etc. etc.
A new tool to help women predict their risk of developing cancer…
Women who want to avoid breast, ovarian and endometrial cancer should avoid booze and cigarettes, keep their weight low, have children early and avoid oral contraceptives. A breakthrough new tool developed at the National Cancer Institute in the USA released today allows women to predict their absolute risk of developing breast ovarian and endometrial cancer. Dr Guy Hingston.
Smokers made to stop before surgery allowed
Smokers will be asked to quit their habit before surgery and will be referred for help while on waiting lists under new medical guidelines. In an effort to better protect patients, a strengthened smoking policy from the Australian and New Zealand College of Anesthetists will require all elective surgery patients to be asked whether they smoke, and for tobacco users to be given referrals to help them quit before their operations.
ANZCA president Dr Lindy Roberts said the guidelines would offer smokers the best chance to avoid life-threatening complications by providing them with support. Dr Guy Hingston.
It was courageous of Angelina Jolie to go public on her bilateral mastectomy & reconstruction, although we are now doing this surgery more often for women who are breast cancer gene (BRCA1 or 2) positive. Preventing breast cancer is much better than trying to cure it! Guy Hingston.
Fatal Toll of Cancer Test Snub
Australians are shunning the cancer test that could save their lives with about half those eligible refusing the chance to be screening for bowel, breast and cervical cancer. The latest data shows just 40 per cent of the three million Australians aged over 50 who were sent a free bowel cancer test in the mail completed it in the first five years of the government program. This is despite researchers estimating 20-30 lives per week could be saved by a higher take-up rate. Similarly, only 55 per cent of women are undergoing breast screens and just 57 per cent are having tests for cervical cancer, the Department of Health and Ageing told a Senate estimates committee.

RACGP launches 8th Edition of the ‘Red Book’
The Royal Australian College of General Practitioners has just launched the 8th Edition of the Guidelines for Preventive Activities in General Practice (the red book). This is a synthesis of evidence-based guidelines from Australian and international sources and provides recommendations for everyday use in general practice. The red book provides a single entry point to common conditions seen in Australian general practice and offers practical advice on the kind of screening and services that should be provided to the general population.
Breast Cancer Screening Halves Risk of Death from Breast Cancer
One of the largest breast screening studies in the world found women halve their risk of dying from breast cancer if they are screened regularly. The research involving about 4000 women from the Western Australian BreastScreen program found screening rates were much lower among women who died from breast cancer. The results were similar to studies carried out in South Australia and around the world, according to the study just published in the journal Cancer Epidemiology, Biomarkers and Prevention.
By comparing the results with other studies, researchers estimated regular breast screens reduced the risk of death by 49 per cent.
Prevention: Eat less and live longer
Eating 40 per cent less food could extend a person’s life by 20 years, according to scientists. Age-related diseases such as cardiovascular disease, cancer and neurodegeneration could be combated by reducing food intake, it is claimed. Researchers at the Institute of Health Ageing at University College London is looking at how the life of a rat can be increased by up to 30 per cent by reducing its food. One of the study’s lead researchers said: “If you reduce the diet of a rat by 40 per cent it will live for 20 or 30 per cent longer. So we would be talking 20 years of human life.”
Federal Government increases Bowel Screen Funding
The life-saving National Bowel Cancer Screening Program will be expanded under the 2012-13 Budget to provide additional screenings to people aged 60 and 70. The program will receive a $49.7 million boost and be extended to screen Australians turning 60 from 2013 and 70 from 2015. This achieves regular five yearly screening for the at-risk population between 50 and 70 years of age. The program will be further extended in 2017-18, when a phased implementation of biennial screening will commence, beginning with 72 year olds. Invitations to undergo screening every two years will then be progressively extended to all Australians between 50 and 74 years of age. Currently, bowel cancer screening is provided free to people aged 50, 55 and 65.
Sharp rise in women with lung cancer
The rate of new lung cancer cases in Australia is raising sharply for women while dropping for men, new government data shows. The report, Lung Cancer in Australia: An overview, was released yesterday by the Australian Health and Welfare Institute and Cancer Australia. It revealed that the rate of new lung cancer diagnoses rose by 72 percent for women but fell by 32 per cent for men between 1982 and 2007.
