Biostatistics Training Initiative

Leaders

Dr. Richard Cook, University of Waterloo
Dr. Gregory Pond, McMaster University

Background

Recent technological advances have led to far more complex and much larger datasets in cancer research. There is a critical need for biostatisticians who can work with these data, ensuring they can be used to inform on the next generation of cancer treatments. Since 2010, the Biostatistics Training Initiative (BTI), previously known as the Oncology Research Training and Methods Program (ORTMP), has placed Master’s students from the University of Waterloo in eight-month internships with mentors at Ontario cancer centres. In doing so, the BTI is training the next generation of biostatisticians in the province, ensuring they are equipped with the technical knowledge, skill set and experience to deal with the changing landscape of cancer treatment and clinical trials.

Based on the success of the program in its first five years and feedback from the Ontario research community regarding its continued need for training, expertise and placement, the BTI expanded in 2016. The new expanded BTI engages a broader group of trainees, including PhDs and postdoctoral fellows, and fosters a sense of community amongst participants through a visiting lecture and monthly seminar series.

The BTI is funded through the Ontario Institute for Cancer Research.

Internships

The BTI Internship Program is a continuation of the earlier OICR-funded ORMTP in which selected top Master’s students in Biostatistics from the University of Waterloo are placed in eight-month internship positions in cancer research centres across Ontario with joint mentorship by a biostatistician and an oncology researcher. Up to four fully funded placements will be made each year from 2016-2020.

Fellowships

The BTI Fellowship Program is designed to support doctoral and postdoctoral training in biostatistics for cancer research. The primary objective of the Program is to support the training of the next generation of biostatisticians in the province, ensuring they are equipped with the technical knowledge, skill set and capability for the application of rigorous quantitative methods for cancer research. Through the receipt of a BTI Studentship/Fellowship Award, biostatistics or statistics doctoral students and postdoctoral fellows at an Ontario university will engage in interdisciplinary, collaborative cancer research with investigators located at an Ontario Host Institution.

Any questions about these awards or how to apply may be emailed to scientificsecretariat@oicr.on.ca.

Seminar series

A monthly seminar series will be held by WebEx/teleconferencing on advanced issues in clinical and population health advances, as well as methodological challenges arising in cancer research. The aim is to engage clinicians, statisticians, interns and fellows. The focus of the seminars will include:

  1. recently completed high impact trials in oncology within the group and internationally,
  2. recent developments in the design and analysis of cancer clinical trials,
  3. biostatistical and more general methodological challenges arising in the planning or conduct of trials, and
  4. reports of ongoing methodological research conducted by engaged faculty, students and interns.

BTI Seminar Series

September 25, 2018, 2 – 3:00 p.m.

Dr. David Soave, PhD, Assistant Professor, Department of Mathematics, Wilfrid Laurier University

Population Health Cohorts and Two-Phase Studies

Large prospective cohorts like the Canadian Partnership for Tomorrow Project (CPTP) follow participants longitudinally and capture incident cases of disease. In two-phase studies, researchers select a subset of the complete cohort based on observed outcomes and covariates and measure additional, possibly expensive, variables. In the CPTP, blood samples are collected and stored when participants enrol. During follow-up a small fraction of the cohort will present with rare diseases, and researchers often select a matched case-control sample and obtain biological information from their blood samples, seeking to discover biomarkers that predict disease. This presentation will review methods for analyzing rare events based on two-phase studies and discuss areas needing development, including study design, methods for assessing genomic and other risk factors, and predictive modelling. An illustration will be based on predicting leukaemia risk in healthy individuals.

Key presentation objectives:

  • Describe the data arising from large, prospective population cohorts such as the Canadian Partnership for Tomorrow Project
  • Present issues related to the design and analysis of two-phase (case-cohort) studies involving expensive covariates
  • Demonstrate penalized regression for building a multivariate prediction model for leukaemia risk based on two-phase study data

Biosketch:

David Soave is an Assistant Professor in the Department of Mathematics at Wilfrid Laurier University.  Prior to joining WLU, David was a postdoctoral fellow with the Biostatistics Training Initiative working in Computational Biology at the Ontario Institute for Cancer Research.  He completed his a PhD in Biostatistics (2016) at the University of Toronto while working in the Genetics and Genome Biology Department at the Hospital for Sick Children.  David’s research interests are focused on statistical genetics, predictive modeling for health outcomes, and the design and analysis of two-phase studies.

TExamining cancer screening adherence in Ontario using multistate transitional models.

Abstract:
Understanding disparities among women in breast cancer screening adherence is of considerable interest, however prior work has been methodologically limited. Our work longitudinally examines adherence to screening, and determines factors associated with becoming adherent. The cohort consisted of 2, 537, 960 women age 50-74 from Ontario, Canada. Using age as the time scale, a relative rate multivariable regression was implemented under the 3-state transitional model to examine the association between covariates (all time-varying) and the rate of becoming adherent. Individual- and physician-level characteristics played an important role in a woman’s adherence to screening. Our research improves the quality of evidence regarding disparities among women in adherence to breast cancer screening, and provides a novel methodological foundation to investigate adherence for other types of cancer screening, including cervix and colorectal cancer screening.

Methodology to Identify Environmental and Host Genomic Association on Human Microbiome Data
Dr. Wei Xu
Assistant Professor, University of Toronto, Dalla Lana School of Public Health

Abstract:
Technological advances in genomic sequencing have enabled researchers to unveil the wide variability of bacteria presented within different locations of the body, i.e. the microbiome, and how it relates to disease. However, our understanding of how microbiomes affect diseases is still unclear. It is necessary to better understand both environmental and host genetic factors impact the composition of the microbiome to improve disease management. Powerful statistical and bioinformatics tools are needed to overcome these knowledge gaps.

Senior Investigator, Cancer Clinical Trials Group, Queens University

BTI title slide from Friday November 25
Download the slides

Abstract:
The Phase II trial has a pivotal role in drug development since the decision to proceed with further evaluation of a drug/ drug combination is based on the efficacy and safety data generated from this type of study. Important additional generated from the Phase II trial may include elucidation of the mechanism of action of a new therapy and delineation of the target population for administration. The objectives of this webinar are to provide the clinician perspective on Phase II trial design and conduct including classification of designs and statistical framework. Examples of actual clinical trials will be drawn from the casebook of the Canadian Cancer Trials Group.

Abstract:
Cancer clinical trials are routinely designed on the basis of event-free survival time where the event of interest may represent a complication, metastasis, relapse, or progression. This talk is concerned with a number of statistical issues arising from the use of such endpoints including the interpretation of results based on composite endpoints, the consequences of naïve analysis of event times subject to dual censoring schemes, and the causal interpretation of treatment effects. Related issues in the joint analysis of longitudinal and survival data will also be highlighted.
