Breaking Down Barriers: The Urgent Need for Equitable Biomarker Testing in Canada
Breaking Down Barriers: The Urgent Need for Equitable Biomarker Testing in Canada
Cancer is the leading cause of death in Canada, with nearly half of Canadians expected to face a diagnosis in their lifetime. Precision medicine—treatments tailored to an individual's unique cancer profile—offers the best chance for effective and less toxic therapy. But this approach depends on timely biomarker testing, which is far from accessible to all Canadians.
A recent article published in Current Oncology in 2024 by Snow et al. highlights critical gaps in Canada’s healthcare system that prevent equitable access to biomarker testing. This testing is essential for identifying genomic mutations in tumors, guiding targeted treatments, and improving patient outcomes. Yet, systemic barriers—funding limitations, interprovincial disparities, and lack of awareness—mean that many Canadians are missing out on potentially life-saving options.
What is Biomarker Testing, and Why Does It Matter?
Biomarker testing, also known as molecular or genomic testing, analyzes tumor DNA to identify genomic mutations that can inform treatment decisions. This allows oncologists to prescribe therapies that directly target a cancer’s unique characteristics, often improving outcomes and reducing unnecessary side effects.
For example, in lung cancer, biomarker testing can reveal mutations like EGFR, ALK, or KRAS, which determine whether a patient is eligible for specific targeted therapies. Without timely testing, patients may receive standard treatments that are less effective or have harsher side effects.
Barriers to Biomarker Testing in Canada
Despite its proven benefits, biomarker testing is not consistently available across Canada. Snow et al. outline several challenges:
Lack of Awareness: Many patients and even some healthcare providers are unaware of the importance of biomarker testing. Without informed discussions, crucial tests may not be ordered.
Long Wait Times: Delays in testing and result reporting prevent timely treatment decisions. Biomarker results should ideally be available before the first oncologist appointment, but this often doesn’t happen.
Geographic and Provincial Disparities: Access varies widely between provinces and urban versus rural areas. Some patients must travel long distances or face outright denial of testing due to local policies.
Financial Barriers: Many tests are not publicly funded, forcing patients to pay thousands of dollars out-of-pocket or seek coverage through private insurance.
Limited Standardization: There is no national policy ensuring equal access to biomarker testing, leading to inconsistent guidelines and practices across the country.
The Call for Change
To address these inequities, the article recommends:
Standardizing biomarker testing across Canada to ensure every patient has equal access, regardless of location.
Implementing reflex testing, where biomarker tests are automatically conducted when a cancer diagnosis is confirmed.
Increasing physician and patient education about the benefits of genomic medicine.
Securing public funding for biomarker testing to remove financial barriers.
