Improving Quality of Life

Now Recruiting Research Participants


The Canadian/US Integrative Oncology Study (CUSIOS). Advanced integrative oncology treatment for patients with advanced stage cancer

The OICC is now actively recruiting patients to participate in this observational study. Working in partnership with Bastyr University, the OICC and CCNM research have initiated a North American study to explore the impact of advanced integrative care delivered by NDs for patients with advanced cancer. Seven clinics across NA are recruiting patients to participate in this prospective observational study to describe quality of life and survival outcomes for patients with advanced stage breast, colorectal, ovarian, and pancreatic cancers. This study will run over six years with the goal of enrolling over 400 patients with late stage cancer. Outcomes associated with quality of life and survival will be assessed. Potentially eligible patients at the OICC may be contacted by their Naturopathic Doctor for study participation.

Please contact Research Fellow Dr. Julie Ennis, PhD; (; 613-792-1222) to learn more about this study.

High-Dose Vitamin D3 Supplementation in Stage 4 Colorectal Cancer Patients

As part of a collaborative research study with InspireHealth in British Columbia, the OICC is seeking people diagnosed with Stage IV metastatic colorectal cancer to participate in this randomized, controlled study assessing the tolerability and toxicity of high-dose vitamin D3 supplementation. Participants will be randomized into either a high-dose vitamin D treatment group or a control group. Both groups will also maintain their current anti-cancer treatments.

Oncology SONAR (Study Of Natural Health Product Adverse Reactions)

The OICC is collaborating with the CARE Program for Integrative Health and Healing at the University of Alberta to conduct a study that investigates suspected adverse reactions associated with the use of prescription drugs and/or natural health products such as herbs and other supplements. We are asking all people who visit the OICC for a clinic consultation to complete a brief questionnaire assessing their use of drugs and natural health products, and whether they have experienced an adverse event. People who indicate that they have experienced an adverse event will be invited to participate in a voluntary telephone interview lasting up to 1 hour to answer some questions about the adverse reaction as well as any drugs, herbs, supplements and other health-related products used over the past month.

Cross-Cultural Differences in the Breast Cancer Trajectory

English-speaking Chinese and White women who are living cancer-free after a previous breast cancer diagnosis are being recruited for a study investigating cultural differences between female breast cancer survivors. The study is looking for women between the ages of 30 to 70 years residing in Ottawa or Toronto. If you are interested in participating (or know someone who may be), please contact Cynthia Wan, the PhD student coordinating the study (or pass along her contact information) at or 613-562-5800 ext. 3892 for the complete eligibility criteria.

Participation in this study involves two steps: 1) providing saliva samples over two consecutive days, and 2) coming to the laboratory at the University of Ottawa or Ryerson University to complete a brief psychological experiment (90 to 120 minutes). Hair and saliva samples will be collected and participants will also be asked to complete a set of questionnaires. You will receive $50 as compensation for any travel costs incurred. Selection for participation is on a first-come, first-served basis.
