Precision Medicine and AI Poised to Revolutionize Hereditary Breast cancer Treatment
Barcelona, Spain — An international collaboration of breast cancer research groups, Soli and Geicam, recently convened with the Seom section of hereditary cancer for the XI Day on hereditary breast cancer. At the April 17, 2025 meeting, medical experts focused on the latest advancements in precision medicine, artificial intelligence, and genetic testing that promise to transform the landscape of hereditary breast cancer management.
The conference, coordinated by Judith Balmaña, a medical oncologist at Vall d’Hebron – Vhio (Barcelona) University Hospital; raquel Andrés, medical oncologist at the Lozano Blesa University Hospital (Zaragoza); and Elena Aguirre, medical oncologist at the Quirónsalud Zaragoza hospital, drew over 100 oncology professionals. Key discussions centered on integrating emerging technologies to personalize therapeutic strategies,optimizing treatment for each patient’s specific situation.
The Clinical Meaning of Hereditary breast Cancer
Hereditary breast cancer (HBC), while accounting for only an estimated 5% to 10% of all breast cancer cases according to the American Cancer Society, carries significant clinical implications. Patients frequently enough present with the disease at a younger age and may develop bilateral tumors (affecting both breasts) or multiple primary tumors within the same breast. These factors necessitate tailored prevention and treatment approaches.
Furthermore, identifying a germline pathogenic variant, or a hereditary mutation, extends beyond the individual patient, directly impacting family members. Genetic counseling and monitoring programs can benefit multiple relatives by assessing and managing their risk.
Precision Medicine: A New Era in HBC Management
The meeting underscored the potential of precision medicine to revolutionize the management of hereditary breast cancer. The agenda focused on the clinical submission of genetic knowledge, the development of new predictive tools, and the consolidation of targeted treatments.
Balmaña, coordinator of the event and a member of Soli, emphasized the importance of current research, stating that, “Hereditary breast cancer remains a paradigm of biological, genetic, social and therapeutic knowledge of breast cancer. In recent years we have advanced greatly in the characterization of the genetic alterations involved and in the possibility of making more precise risk estimates for each woman.”
Unlocking the Genetic Component of breast Cancer
Characterizing pathogenic variants in genes such as *BRCA1*, *BRCA2*, *PALB2*, and *TP53*, along with the growing understanding of polygenic risk (the combined effect of multiple genes), allows for the creation of increasingly precise risk profiles. These profiles inform tailored prevention strategies and early detection protocols, considering factors like the age to begin screening, the frequency of screenings, and the appropriate imaging tests.
Currently, models are being validated that integrate clinical, family, genetic, and imaging variables to calculate an individual’s risk of developing hereditary breast cancer. These tools promise to customize follow-up care from early adulthood, adjusting the frequency of imaging and facilitating informed decisions about surgical or medical risk-reduction strategies.
“We are investigating whether these models can help change the early detection of breast cancer based only on age or family history incorporating other variables such as genetic risk, breast density, or the result of the image. The objective is to achieve a personalized and actionable prediction or preventive medicine,” said Balmaña.
Artificial Intelligence: Transforming Radiological Image Analysis
One of the moast groundbreaking aspects discussed was the application of artificial intelligence in radiological image analysis. Mikael Eriksson, from the Karolinska institute in Sweden, presented research on predicting cancer risk from mammograms using validated algorithms in the Swedish population.
These algorithms have demonstrated a high discriminatory capacity for predicting short-term events (≤2 years), offering the potential for earlier and more accurate detection of breast cancer.
Targeted Therapies and Clinical Trial Advancements
the conference also spotlighted therapeutic advances, notably the impact of targeted therapies, notably PARP inhibitors, in patients with germline pathogenic variants. Recent studies have demonstrated benefits not only in metastatic disease but also in early stages, leading to improved overall survival rates.
Raquel Andrés, coordinator of the day and a member of Geicam, moderated the session on therapeutic advances, emphasizing the critical need to translate clinical trial results into patient care. “Therapeutic innovation has brought important improvements in the treatment of hereditary breast cancer, advocating a personalized medicine, with directed therapies such as PLP inhibitors, CDK4/6 inhibitors and immunotherapy,” said Andrés, who added that “the integration of these treatments is basic in the previous surroundings and after surgery with positive impact on survival.”
The Olympia clinical study, which demonstrated improved global survival with the use of olaparib (a PARP inhibitor) in patients with high-risk hereditary breast cancer, celebrated ten years of follow-up, confirming the durability of its results.
Bridging the Gap: From Evidence to Patient Access
A central challenge identified during the conference is ensuring that evidence-based findings from clinical trials are translated into accessible and equitable protocols for all eligible patients. The availability of genetic testing, the training of healthcare professionals, and the establishment of specialized hereditary cancer units are essential for ensuring that therapeutic benefits reach all women with pathogenic variants in cancer predisposition genes.
The Role of Modifiable Risk Factors
The conference emphasized the importance of modifiable risk factors in reducing breast cancer risk among women carrying pathogenic variants. Lifestyle interventions, including physical exercise, diet, and stress management, were highlighted as key preventive measures to be used alongside medical surveillance.
Elena Aguirre, coordinator of the day and a member of SEOM, addressed this issue with an integrative approach: “Physical exercise has a key role in the prevention and treatment of breast cancer, both in general population and in people with a hereditary predisposition to cancer.” Aguirre added, “Scientific evidence indicates that, in carriers of pathogenic variants in genes such as BRCA1/2, regular physical exercise can delay the appearance of cancer and its positive impact on hormonal regulation, inflammation and immune function makes it a first -order public health tool.”
Aguirre stressed the need for interdisciplinary preventive strategies involving genetics specialists, sports medicine professionals, oncologists, primary care physicians, and public health experts.
A Call to action for Improved Care
The conference concluded with a call to action to further strengthen specialized care pathways for women with a genetic predisposition to breast cancer. Implementing clinical recommendations based on genetic studies, ensuring equitable access to targeted treatments, and integrating genetic counseling into medical decision-making remain top priorities.
Addressing a Counterargument: The Cost of Genetic Testing
While the benefits of genetic testing for hereditary breast cancer are clear, concerns remain regarding the cost and accessibility of these tests. The financial burden can be a significant barrier for many individuals, particularly those from underserved communities.However, several initiatives are underway to address this issue.Many insurance companies now cover genetic testing for individuals who meet certain criteria, and patient assistance programs offered by pharmaceutical companies and non-profit organizations can help offset the costs. Additionally, ongoing research is focused on developing more cost-effective genetic testing methods, making them more accessible to a wider population.
FAQ: Hereditary Breast Cancer and Genetic Testing
| Question | Answer |
|---|---|
| What is hereditary breast cancer? | Hereditary breast cancer is breast cancer caused by inherited genetic mutations, such as those in the BRCA1 and BRCA2 genes. It accounts for about 5-10% of all breast cancer cases. |
| Who should consider genetic testing for breast cancer risk? | Individuals with a family history of breast cancer, especially if diagnosed at a young age, ovarian cancer, or other related cancers, should consider genetic testing. Also, those of Ashkenazi Jewish descent have a higher risk of carrying BRCA mutations. |
