Breast cancer radiotherapy in a single visit provides more convenient option to patients, reduces burden of therapy
Cross-Canada research team moves image-guided ultrasound system into clinical development
Traditional breast cancer radiation treatment requires multiple hospital visits over a period of weeks or months, which may be onerous to patients who live far from hospitals or in remote communities. An alternative radiotherapy technique, Permanent Breast Seed Implantation (PBSI), requires only a single hospital visit, but it involves the implantation of multiple small radioactive metal pellets into the breast of the patient within millimetres of a target. The procedure to administer this treatment is difficult to plan and complex to execute – impeding the adoption of PBSI in the clinic.

OICR takes part in international multicentre study to standardize promising breast cancer digital pathology test
The Ki67 immunohistochemistry assay is a test that can help evaluate the aggressiveness of breast tumours, predict disease outcomes, monitor cancer progression and identify patients who are more likely to respond to a given therapy. Despite its potential to help patients with breast cancer, the analysis of Ki67 has not been widely adopted in the clinic, mostly due to the lack of standardization across laboratories.

Researchers further clarify the role of epigenetic proteins in the development of breast cancer, and discover that inhibiting these proteins could prevent the disease in women at high risk.

New OICR President and Scientific Director comments on breakthrough in breast cancer T-cell immunotherapy
For the first time, a patient’s late-stage breast cancer has been successfully treated with T-cell immunotherapy. This cutting-edge approach, which is currently in clinical trials in the U.S., modified the patient’s naturally-occurring immune cells to fight her tumours that had spread throughout her body. The patient has been cancer free for the past two years and her remarkable tumour regression represents the potential impact of this new immunotherapeutic approach.

Current HER2 tests help predict which breast cancer patients will respond to HER2-targeted therapies, but sometimes these tests provide unclear results. An Expert Panel of pathologists and cancer researchers, including Dr. John Bartlett from OICR, recently published revised clinical practice guidelines for HER2 testing in breast cancer to help improve clarity of HER2 test results.

Biotechnology competition modeled after popular TV program Dragons’ Den
TORONTO, ON (April 12, 2018) – A panel of investor-judges has selected Ontario-based oncology researcher Soror Sharifpoor of Polumiros Inc. as the winner of the 2018 FACIT Falcons’ Fortunes competition. The $50,000 award is intended to support further development of their innovative cancer research. FACIT runs the annual competition as part of its broader mandate to support translating research into Ontario companies to impact the lives of patients with cancer.
Now in its fifth year, the FACIT Falcons’ Fortunes competition is open to any Ontario-based oncology researcher (academics, research institutions, research hospitals and start-ups). Entrepreneurial scientists are invited to pitch innovative research ideas to a panel of four investors in a competition that is modeled after the popular CBC television program Dragons’ Den. The winners receive the $50,000 “Ernsting Entrepreneurship Award.” After follow-up technical evaluation of the underlying innovation, the money funds product development for one year.

Immunotherapy, which boosts the body’s immune system to kill cancer cells, has shown remarkable promise in treating many types of cancer. Now researchers have found a way to use immunotherapy against triple-negative breast cancer (TNBC), one of the most lethal forms of breast cancer. Previously, TNBC was resistant to immune checkpoint inhibitors, a common class of immunotherapies. Using a new strategy, the scientists achieved a cure rate of up to 90 per cent in mouse models.

Endocrine therapy uses hormone antagonists to greatly reduce the risk of disease recurrence in women with early-stage, estrogen-receptor (ER) positive breast cancer. However, the treatment can come with severe side effects. Around 30 per cent of women stop taking the therapy after three years largely due to these negative impacts. Usually patients receive the hormone therapy for five years following initial treatment (e.g., chemotherapy, surgery), but it can also be taken longer-term. A central question facing patients and clinicians is how to balance, in their decision making, the side effects of long-term treatment with the potential reduction in recurrence risk. In short, they want to know: ‘is it worth it?’

Researchers at The Ottawa Hospital and the University of Ottawa have found that a combination of two immunotherapies – oncolytic viruses and checkpoint inhibitors – was successful in treating triple-negative breast cancer in mouse models. Triple-negative breast cancer is the most aggressive and hard-to-treat form of the disease.

Biomarkers that can help predict a patient’s response to a given drug are central to testing new therapies in clinical trials as well as selecting which drugs to use in the clinic. Some of the biomarkers in use today rely on the overall expression of a given gene to predict if a drug will be of benefit. While these types of biomarkers have aided cancer research and treatment, a group led by Dr. Benjamin Haibe-Kains recently published research that is ushering in a new class of biomarkers – those based on gene isoforms (the different expression of the same gene within an individual). This work opens the door to more precise biomarkers.

New software uses machine learning to identify mutations in tumours without reference tissue samples
One of the main steps in analyzing cancer genomic data is to find somatic mutations, which are non-hereditary changes in DNA that may give rise to cancer. To identify these mutations, researchers will often sequence the genome of a patient’s tumour as well as the genome of their normal tissue and compare the results. But what if normal tissue samples aren’t available?

A newly published paper in Genetics in Medicine has reinforced the fundamental importance of collecting information about genetic variances in a single large database. With so much important genetic information being used globally to understand the underlying genetic influences of diseases, researchers and clinicians need an accessible repository to share this information.
