Lung cancer treatments and outcomes are changing, but survival remains a challenge

Lung cancer is the second most common cancer in the world, accounting for 11.4% of all cancers, but with 18.0% of total cancer‐related deaths, it is the leading cause of cancer death.1 In Australasia, the incidence of lung cancer varies between 19.1 and 42.1 per 100 000 population, with the strongest risk factors historically being increasing age and tobacco smoke exposure.2,3 However, the proportion of (predominantly) female never smokers with lung cancer is increasing in many countries, particularly across South‐East Asia, together with an enlarging proportion of adenocarcinomas and molecular mutations, especially of the epidermal growth factor receptor (EGFR).2,4 Lung cancer in never smokers is increasingly being recognised as biologically distinct from smoking‐related lung cancers, although there is overlap with other risk factors such as environmental and genetic interactions, biofuel and occupational exposures, and indoor and outdoor pollution.2,4 The incidence of lung cancer in several developed countries (eg, the United Kingdom and the United States) has started to fall. However, despite a projected fall in age‐standardised lung cancer rates in Australia over the next two decades, the number of deaths from lung cancer is expected to continue to increase due to population growth and ageing.2,5

Treatable traits in asthma: moving beyond diagnostic labels

A precision medicine approach to asthma places the patient at the centre of their care

Asthma is a common inflammatory disease, affecting over 300 million people worldwide,1 including one in nine Australian adults.2 Asthma imposes a major burden on the health care system, on patients, and within society.3 In the late 20th century and the early 2000s, there were major improvements in asthma outcomes, largely because of the introduction of inhaled corticosteroids to treat eosinophilic airway inflammation, and asthma self‐management education initiatives.4 These improvements in asthma outcomes are now being lost. Hospitalisations and mortality from asthma have begun to rise as adoption of new assessment techniques and biomarkers into practice stagnates, and we experience sluggish development of new drug discovery in comparison to other diseases.4 Asthma deaths have risen in Australia, the United Kingdom and the United States,4 with at least one person in Australia dying every day from asthma.2

Barriers to accessing HIV pre‐exposure prophylaxis for Medicare‐ineligible people in Melbourne, Australia: analysis of patients attending the PrEPMe Clinic

Vincent J Cornelisse, Jude Armishaw, Mike Catton, Dean Murphy and Edwina J Wright
Med J Aust 2022; 216 (6): . || doi: 10.5694/mja2.51455
Published online: 4 April 2022

To the Editor: People without Medicare coverage cannot access Pharmaceutical Benefits Scheme (PBS)‐subsidised human immunodeficiency virus (HIV) pre‐exposure prophylaxis (PrEP) or associated clinical care. Rates of HIV infection diagnosis are disproportionately higher among overseas‐born gay and bisexual men compared with Australian‐born gay and bisexual men.1 In response, in June 2020, the Alfred Hospital and the Victorian Infectious Diseases Reference Laboratory established the free PrEPMe Clinic for Medicare‐ineligible people. Data were collected using proformas after patients provided verbal consent (Alfred Health Ethics Committee approval No. 656/18).

Population DNA screening for medically actionable disease risk in adults

Paul A Lacaze, Jane Tiller and Ingrid Winship, For the DNA Screen Investigator Group†
Med J Aust 2022; 216 (6): . || doi: 10.5694/mja2.51454

Australia will take a world‐first step towards offering preventive DNA screening through the public health care system

In adult‐onset genomic conditions, such as hereditary breast and ovarian cancer (HBOC), Lynch syndrome and familial hypercholesterolaemia, certain DNA variants confer high risk of developing future disease.1 DNA screening for these conditions could thereby identify medically actionable genetic risk factors, prompting timely risk management and informed decision making from early adulthood to facilitate early detection or prevention.2 Despite this opportunity, diagnostic rates for these conditions remain low,2,3,4 limited by restricted access to genetic testing and lack of awareness.

“There is a Chinese curse which says ‘May he live in interesting times’. Like it or not, we live in interesting times. They are times of danger and uncertainty; but they are also the most creative of any time in the history of mankind.” — Robert F Kennedy, 1966

As we continue to live through the COVID‐19 pandemic, climate change pressures including floods and fires, anti‐vaccine rhetoric, anti‐science sentiments and war in Ukraine, the words of Robert F Kennedy over 50 years ago ring true. Despite all the uncertainty, science and medicine have made tremendous strides in an unprecedented fashion, as exemplified by the very rapid development, testing and delivery of life‐saving vaccines for SARS‐CoV‐2. The past 2 years of the pandemic have reinforced how important high quality peer‐reviewed medical journals are as a trusted source of the best available information, in order to guide public health and the safe and effective practice of medicine.1 I am very proud of the role of the Medical Journal of Australia throughout the pandemic in publishing living guidelines, new research and evidence‐based viewpoints that have helped shape Australia’s response.1,2

Preparing Australasian medical students for environmentally sustainable health care

Medical educators and representatives of medical student associations in Australia and New Zealand are collaborating on an initiative on climate change and health in medical education

Climate change and environmental degradation are harming the health of Australians and New Zealanders and pose a serious challenge to our health care systems.1,2 The World Health Organization in 2019 identified climate change and air pollution as the top threat to human health globally;3 a threat clearly visible in the sustained air pollution over south‐eastern Australia from bushfire smoke during the 2019–20 bushfire season. The health consequences of the bushfires and the associated prolonged, hazardous air quality prompted the Australian Medical Association and three medical colleges to declare climate change a public health emergency.4 Health care systems also contribute to climate change and environmental degradation. In Australia, health care contributes 7% of the country’s total carbon emissions and produces considerable waste which is either incinerated or sent to landfill.5 Despite these environmental challenges, there has been little response by medical programs to prepare medical graduates to manage the health impacts of climate change, and to practise environmentally sustainable health care. In 2018, we described an initiative to support medical educators and medical student organisations to work collaboratively to develop proposed learning objectives, curricula and learning resources addressing the health effects of climate change.6 This article describes the development of the model graduate outcome statements and learning objectives which have been shared with all medical schools in Australasia.

Parental consent and the treatment of transgender youth: the impact of Re Imogen

Published online: 21 March 2022

Recent legal changes are negatively affecting provision of timely medical care to Australian transgender youth

The number of transgender and gender diverse (henceforth, trans) youth seeking medical treatment has risen sharply over the past two decades in Australia and overseas.1,2 Unique legal requirements for consent to this treatment in Australia have developed through Family Court case law since 2004. Until recently, it was necessary for a young person seeking pubertal suppression or gender‐affirming hormone treatment to secure Family Court approval before treatment could commence, even in circumstances where both parents and the young person’s treating doctors supported treatment and considered it to be in their best interest, and the young person was deemed Gillick competent, which is achieved when a young person has “a sufficient understanding and intelligence to enable him or her to understand fully what is proposed”.3 The requirement for court approval was removed for puberty suppression in 2013 by Re Jamie,4 but the restrictions on gender‐affirming hormone treatment remained until the Full Family Court decision of Re Kelvin in 2017.5

Responding to the rising number of suicides using barbiturates

Bridin P Murnion and Darren M Roberts
Med J Aust 2022; 216 (4): . || doi: 10.5694/mja2.51409
Published online: 7 March 2022

Suicide prevention requires ensuring that social media are responsible and accountable, and that poisoning surveillance systems are adequately supported

Barbiturates have a narrow therapeutic index, and accidental or deliberate poisoning can cause coma and cardiorespiratory arrest. Barbiturate‐related death rates were high in the mid‐20th century, when barbiturates were still commonly prescribed, but safer alternatives mean that clinical indications for prescribing them are now extremely limited.1 Over the past twenty years, however, interest in barbiturates has increased, particularly in their use at the end of life.2

Time for equal access to breast reduction surgery in Australia

Elisabeth Elder
Med J Aust 2022; 216 (3): . || doi: 10.5694/mja2.51386
Published online: 21 February 2022

Women with symptomatic macromastia need relief from a condition that can seriously impair their quality of life

In this issue of the MJA, Crittenden and colleagues report their cost–utility analysis of breast reduction surgery for women with symptomatic breast hypertrophy in Australia.1 Their key finding is that breast reduction surgery is cost‐effective, the cost per quality‐adjusted life‐year (QALY) being considerably lower than the recommended willingness to pay thresholds in the Australian health care system. The authors prospectively assessed health‐related quality of life (SF‐6D utility scores) for 209 women with symptomatic breast hypertrophy before and 12 months after breast reduction surgery. The SF‐6D, a six‐dimensional single health utility score, is derived from the Short Form‐36 (SF‐36), one of the most widely used instruments for assessing health‐related quality of life (range: 0 for death to 1 for perfect health). Their scores were compared with those for 124 women with similar symptoms who had not yet had reduction surgery. The mean SF‐6D scores were similar at baseline, and improved significantly for the women who had undergone surgery (0.313; standard deviation [SD], 0.263 to 0.626; SD, 0.277) but declined slightly (0.296; SD, 0.267 to 0.270; SD, 0.257) for those who had not. The effectiveness of the procedure was measured as the mean differential QALY gain (1.519; 95% confidence interval, 1.362–1.675), obtained at an incremental cost‐effectiveness ratio (ICER) of $7808 per QALY gained.
