Cancer researchers often confront quantitative challenges and puzzles that are best addressed by biostatisticians – specialists in a field for which there is a growing demand. In a 2008 survey of Ontario oncologists, eight in 10 respondents identified the lack of trained biostatisticians as a factor limiting their progress in cancer research. OICR has recently renewed funding for the Biostatistics Training Initiative (BTI) following a successful review. With this funding, the BTI will continue to benefit Ontario’s cancer research community and develop the next generation of cancer biostatisticians. The BTI is run in partnership with in the University of Waterloo and McMaster University.

Strict e-cigarette policies are meant to keep non-smokers from smoking. But they may also be preventing many smokers from quitting
Regulatory strategies on electronic cigarettes vary from country to country. The International Tobacco Control Policy Evaluation Project, led by Dr. Geoffrey Fong, explored how different regulatory environments might influence the effectiveness of e-cigarettes for smoking cessation. This research could be used to help shape e-cigarette control policies that minimize the potential health risks and recognize the potential benefits of e-cigarettes as a smoking cessation aid.

According to the World Health Organization (WHO), tobacco is used by over 1 billion people and is the number one preventable cause of death and disease. Tobacco—especially smoked tobacco—causes 30 per cent of the world’s cancer cases and so tobacco control is the number one strategy for preventing cancer. Tobacco use kills six million people a year. It also brings a staggering economic cost of US$1 trillion a year in health care expenditures and lost productivity.
The WHO Framework Convention of Tobacco Control (FCTC) is a treaty that was created to combat the global tobacco epidemic. Currently, 179 countries and the European Union have joined the treaty, which obligates countries covering about 90 per cent of the world’s population to implement a set of strong evidence-based measures to reduce tobacco use. The FCTC is, in effect, the most extensive cancer prevention effort in history. The FCTC recently marked ten years since its coming into force. But how much impact have these measures made? A research team centered at the International Tobacco Control Policy Evaluation Project (the ITC Project), University of Waterloo (UW), recently published a study that demonstrated the positive impact of the FCTC on smoking rates.
Dr. Shannon Gravely, Research Assistant Professor at UW, was the lead author on the study, which was published in Lancet Public Health in March. The study examined how the implementation of five key FCTC tobacco policies affected smoking prevalence across 126 countries. “We looked at the highest-level implementation (i.e. fully satisfying the requirements of the FCTC) of these measures between 2007-2014 and the smoking prevalence estimates for the first 10 years of the FCTC, from 2005 to 2015,” says Gravely. “We found a strong and statistically significant association between the number of these FCTC measures and decreases in smoking rates.”
The five tobacco demand-reduction measures studied by the ITC Project team were: 1) Taxation; 2) Smoke-free policies; 3) Warning labels; 4) Bans on advertising, promotion and sponsorship; and 5) Cessation programs. The researchers found that with each additional measure implemented at its highest level, countries experienced an average decline in smoking prevalence of 1.57 percentage points, or a relative decrease of 7.09 per cent.
“It is indeed good news that the FCTC measures are associated with decreasing the number of smokers, but the bad news is that few countries are actually implementing these effective measures,” says Gravely. Only a fifth of the countries covered in the study had implemented taxes on tobacco at the highest levels called for under the treaty. “We found this to be particularly worrisome as it is known that increasing the price of tobacco via taxes is the most effective way to reduce tobacco use,” says Gravely. In fact, none of the five key FCTC policies had been implemented by even half of the countries.
“Overall, the study found that these measures, when implemented at their highest levels are very effective at reducing smoking rates,” comments Gravely. “Our findings highlight the importance of tobacco control measures in improving global health by directly decreasing the rates of smoking thus in turn indirectly reducing tobacco-attributed-non-communicable diseases.”
Dr. Geoffrey Fong, Professor of Psychology and Public Health and Health Systems at UW and OICR Senior Investigator, is Chief Principal Investigator of the ITC Project. Fong, a co-author of the article, commented, “This study should be a call to arms for governments to strengthen and accelerate their efforts to fully implement the FCTC secure in knowing that such efforts will significantly reduce the devastation caused by tobacco products in their countries.”

OICR’s Geoff Fong receives major funding to examine e-cigarettes and the impact of public health policy
Around the world it has become common to walk down the street and see a new trend – people vaping (using e-cigarettes). The widespread use of e-cigarettes has caught the attention of the scientific community. Recently, OICR Investigator Dr. Geoff Fong was awarded funding from Canadian and U.S. federal funding agencies to evaluate the impact of e-cigarettes and determine the effectiveness of policies around their use.

For many years, smoking was considered a sophisticated and glamorous pastime advertised to millions as a source of relaxation and freedom. But today, in the face of decades of research showing the harmful short and long-term side effects of smoking, including cancer and lung disease, that perception has almost entirely disappeared.
Yet many people continue to smoke. Almost 15 per cent of Canadians (more than four million people) were active smokers in 2013, with the majority of smokers reporting that they smoked daily. Tobacco use is the leading cause of cancer and cancer deaths in the world and it contributes to many other serious health conditions. According to the World Health Organization (WHO), tobacco kills approximately six million people per year globally. Preventing the use of tobacco and helping users quit are the important first steps in a long-term effort to ensure fewer people develop and die from lung cancer and other related diseases.

This meeting sets stage for next four years of biostatistics training
As the cancer research landscape rapidly changes, so to do the needs of hospitals and research institutes for the types of young researchers on their teams. New technological advances have led to the need for qualified biostatisticians who can work with the large amounts of data that are now an essential part of many cancer research projects.
