Biostatistics Training Initiative (BTI) alumnus brings on new BTI trainee to study Canada’s largest population health dataset using today’s top technologies
Recently, circulating tumour DNA (ctDNA) – DNA released from cancer cells that freely circulates in the blood – has garnered much attention not only as an alternative to traditional tissue biopsies, but as a potential blood-based biomarker for early cancer diagnosis.
The ability to detect the earliest blood-borne traces of cancer largely rests in our ability to determine which molecular markers indicate that a cancer is developing – or which patterns in ctDNA can predict whether a cancer will grow. Dr. David Soave sees this as a mathematical challenge that, if solved, could have huge impact for better predicting and diagnosing a wide variety of cancers.
“To find cancer earlier or predict who will develop the disease, we need to carefully compare human samples from those who will develop cancer and samples from those who won’t,” Soave, an Assistant Professor at Wilfrid Laurier University and OICR Associate, says. “This type of challenge requires new statistical models, methods and computational techniques that can decipher large, complex and high-dimensional data.”
Last year, the Canadian Partnership for Tomorrow Project (CPTP) unified the data from several provincial longitudinal health studies into a national cohort consisting of more than 325,000 participants who are voluntarily donating their health and biologic samples to research. As some CPTP participants will develop disease and others will not, this dataset provides an unprecedented resource for researchers like Soave to discover the earliest traces of cancer that appear several months to years prior to an initial diagnosis.Continue reading – Blood samples, biostatistics and a fresh perspective: The makings of a cancer prediction machine

Big data are ushering in a new era of individualized cancer care and prevention, but not without conceptual and practical challenges. Canadian advances in genomics will be made by or limited by bioinformatics analytical capacity as well as the ability to store and analyze data in new and more sophisticated ways.
To help realize the potential of genomics research in cancer, the Canadian Data Integration Centre (CDIC) platform, led by OICR, offers third generation bioinformatics and genomics tools to support both functional and clinical genomics research. CDIC is the largest academic cancer informatics program in the country – offering customizable, client-oriented access services for data challenges across diverse research areas.

Acute myeloid leukemia (AML) progresses quickly and requires treatment soon after diagnosis, but the disease begins long before becoming symptomatic. Early indicators of AML were thought to be indistinguishable from healthy aging. But now, an international group of researchers led in part by Dr. Sagi Abelson, a postdoctoral fellow in the lab of Dr. John Dick at the Princess Margaret Cancer Centre, has discovered distinctive traces of AML in patients up to 10 years before they were diagnosed with the disease.

Study shows that environmental exposures such as air pollution are more determinant of respiratory health than inherited genetics
Toronto (March 6, 2018) – Researchers have found strong evidence that environmental exposures, including air pollution, affect gene expressions associated with respiratory diseases much more than genetic ancestry. The study, published today in Nature Communications, analyzed more than 1.6 million data points from biological specimens, health questionnaires and environmental datasets, making this study one of the largest ever to examine the relationship between gene expression and environmental stimuli. These findings represent a groundbreaking use of big data to uncover the environmental factors that are behind diseases and inform strategies for prevention, an approach that would apply to a number of diseases, including cancer.

For scientists working to understand diseases and develop new treatments, access to data is key. Ontario Health Study (OHS) participants have already provided the Study with a wealth of information about their health and lifestyle through the OHS online survey, and in some cases, blood samples and physical measures. Researchers can use this information to uncover the causes of various chronic diseases and to inform further research. Now, OHS participants are being given an opportunity to further help researchers by completing a follow-up questionnaire.

OICR researcher receives $2 million in federal funding to study metabolic conditions that can lead to cancer
Dr. Philip Awadalla and the Ontario Health Study team.
Chronic health conditions place a heavy burden on patients and their families, and cost the healthcare system and the Canadian economy staggering amounts. Chronic diseases were behind 67 per cent of total direct costs in health care and 60 per cent of total indirect costs as a result of early death, loss of productivity and foregone income, according to a 2006 study by the Public Health Agency of Canada. Globally, non-communicable disease (NCD) was made a priority by the World Health Organization, leading to the formation of the NCD Alliance and the Sharjah Declaration, which aims to reduce the global burden of NCDs.

$2 million in new funding from Canadian Institutes of Health Research will help Ontario team study metabolic syndromes
Toronto (May 2, 2016) – Dr. Philip Awadalla, Senior Investigator at the Ontario Institute for Cancer Research and Principal Investigator for the Ontario Health Study has been awarded $2 million by the Canadian Institutes of Health Research (CIHR). The award will fund the study of the role of both genes and the environment on the development of metabolic syndrome, a cluster of medical conditions that are common in aging adults, including obesity, hypertension, high cholesterol, high blood sugar and insulin resistance.
These conditions are considered to be both risk factors and causal factors in the development of cancer and chronic diseases like heart disease, stroke and diabetes. A better understanding of how to prevent and treat the conditions of metabolic syndrome could also help in the design of new strategies to prevent these diseases before they develop.
