Research examines healthcare experience for cancer patients who also have diabetes

Hospital waiting room

Dr. Lorraine Lipscombe investigates why the 20 per cent of cancer patients with diabetes often experience worse outcomes

Several studies show that health outcomes – such as overall survival and preventable hospitalizations – are worse for cancer patients who also have diabetes. However, the reasoning behind this disparity is unclear. Dr. Lorraine Lipscombe, an endocrinologist at Women’s College Hospital and Diabetes Canada Investigator Award holder, is investigating why these differences exist and what we can do to avoid preventable complications.

Researchers investigated almost 200,000 cases of breast cancer: Here’s what they found

Dr. John Bartlett poses for a photo at a table next to a laptop computer displaying lines of code.

 

Research team finds aggressive breast cancers are less frequent than previously thought, and less aggressive breast cancers need more of our attention.

Different subtypes of breast cancer respond to treatment differently and require different treatment approaches. Understanding the distribution of these subtypes and their respective clinical outcomes allows researchers to better understand the disease and identify key research priorities that may have been previously overlooked.

Breast cancer radiotherapy in a single visit provides more convenient option to patients, reduces burden of therapy

Seeds used in radiation therapy are shown, along with a penny to provide scale.

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.

Breaking down barriers to translation: A case of standardization in digital pathology

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.

Targeting epigenetic proteins could help prevent breast cancer

Dr. Julie Livingstone

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

Dr. Laszlo Radvanyi

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.

New guidelines for HER2 testing in breast cancer

An image of the HER2 protein.

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.

Restorative Breast Cancer Solution Start-Up Wins the 2018 FACIT Pitch Competition

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.

Scientists create method to sensitize triple-negative breast cancer to common immunotherapy

Drs. Marie-Claude Bourgeois-Daigneault and John Bell

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.

Large-scale study provides clearer picture of recurrence risk for ER-positive breast cancer

Dr. John Bartlett

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?’

Study shows virus-boosted immunotherapy can be effective against aggressive breast cancer

The Maraba virus is seen under an electron microscope

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.

Novel approach yields four robust biomarkers for breast cancer drug response

Dr. Benjamin Haibe-Kains and Zhaleh Safikhani pose for a photo

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.
