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.

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.

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.

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?’

OICR launches Tissue Portal to support tissue-based research projects

Fu Yan - In the lab.

OICR’s Tissue Portal is a new central entry and exit point for human tissue derived samples handled at OICR. This will serve as a gateway for tissue-based research projects to access over 100 services and resources at OICR being made available through the OICR Collaborative Research Resources on a cost-sharing basis. The Tissue Portal will standardize and streamline the storage, processing and distribution of samples for collaborative research studies at OICR.

Could diagnosing cancer as rare diseases improve outcomes for patients?

Dr. John Bartlett

Breast cancer is the most common form of cancer amongst women in Canada and worldwide, but despite its prevalence, a group of researchers believes that it should often be treated as a rare disease. Doing so would change clinical approaches and improve treatment for patients.
