Academic Research Activities


Last update: July, 2020

Dr. Ragaz initiated his clinical research activities in the late 1970s at the British Columbia Cancer Agency (BCCA), University of British Columbia, Vancouver, BC. These continued between his 2003-2008 tenure at McGill University, Montreal, PQ, and currently (2020) as Clinical Professor, through the School of Population and Public Health [SPPH], University of British Columbia, Vancouver, BC, Canada.


Summary of recent and past activities


2010 - 2020 [present] Breast Cancer [BrCa] Outcome Projects - CANADA. Long-term [BrCa] Incidence & Mortality trends in the Canadian Provinces, correlating outcomes with the organization of cancer care (collaboration: Public Health Agency of Canada, Canadian Cancer Registry, and Statistics Canada).

2010 - 2020 [present]. Breast Cancer Outcome Projects - CHINA. Comparative analyses of Breast Cancer Incidence and Mortality trends between urban and rural China (Collaboration: Cancer Registries in Shanghai & Qidong).

1990s - 2020. HRT reviews. Since the 1990s, Dr. Ragaz and his team have been monitoring, and at times providing additional analyses of HRT data to clarify new HRT paradigms [i.e., Estrogen Breast Cancer DUALITY; mechanisms & estimates of estrogen-associated Br Ca mortality reduction]. Provided also is evidence for strengths and shortcomings of existing HRT trials, to identify issues responsible for the lack of clarity of HRT data.

These include the recent HRT analyses by Dr. Ragaz and his team [AACR, 2019], highlighting the association of estrogen-based HRT with substantial and statistically significant [BrCa] mortality reduction in the PREVENTION setting versus no BrCa mortality reduction with Tamoxifen; and estimates of Number of avoided deaths due to estrogen-based HRT, as based on recent results of randomized trials - (see below, HRT references).

2000s - 2020. Issues of Breast Cancer Prevention:

2000 - 2004. BCCA Molecular Biology project with Tissue Microarrays. Start and completion of the first phase of the BCCA Tissue Microarray project, in collaboration with the UBC Pathology Group [GPEC] and several groups of international collaborators [Drs. M. Lippman, G. Sledge, K. Miller, S. Badwe, A. Brodie, A. Harris, D.Hayes, et al.] This project correlated, in 930 patients participating in British Columbia Breast Cancer trials, the 20-year breast cancer survival outcome according to the expression of novel molecular markers: Her2/Neu, VEGF, Cox2, uPA, Aromatase, EMSY, etc.

1990 - 2000. Breast Cancer Outcome unit. In the late 1980s, Dr. Ragaz and his team conceptualized and obtained funding for the British Columbia Breast Cancer Outcome Unit - soon afterwards becoming one of the largest and most active Clinical Breast Cancer Outcome units in North America.

1997 - 2005. Post-Mastectomy Radiation therapy. This seminal British Columbia randomized trial [of Post-Mastectomy Radiation therapy versus not] coordinated by Dr. Ragaz and his team (New England Journal of Medicine, 1997; Journal of National Cancer Institute, 2005) helped to change in the late 1990s, along with a similarly designed Danish trial, the post-mastectomy radiation therapy guidelines for stage I-II breast cancer.

1977 - 1985. Neoadjuvant Therapy Program for early Breast cancer was piloted since the late 1970s by Dr. Ragaz's team in British Columbia, and eventually led to the guideline-acceptance of Neo-Adjuvant therapy for Breast Cancer in North America and Europe. In the process, Dr. Ragaz and his team conceptualized Neoadjuvant setting as an ideal one to test new agents for cancer efficacy, substantially reducing the time required in testing and activating new agents into guidelines.

1978 - 1980. Aromatase Inhibitors with Medical Adrenalectomy (Aminoglutethimide) in British Columbia and Canada. One of the first international projects of Aromatase Inhibitors for breast cancer therapy.
