Advancements in Breast Cancer Research at UT Austin
Recent advancements in technology and research have greatly improved breast cancer treatment. At the University of Texas at Austin, scientists are working on innovative methods to better detect and treat even the most challenging forms of this disease. This research is part of a collaborative effort involving various fields to bring new insights and solutions.
The anticipated UT Medical Center, linked with Dell Medical School and the esteemed MD Anderson Cancer Center, is set to enhance how researchers and doctors work together, speeding up progress in cancer care and research.
Tackling Aggressive Breast Cancers
Some breast cancers, like inflammatory breast cancer (IBC) and triple-negative breast cancer (TNBC), are notably tough to treat. Even though they are rare, these aggressive types make up a significant portion of breast cancer deaths due to their resistance to conventional treatments.
To combat this, researchers from UT and the MD Anderson Cancer Center are pooling their resources. By analyzing samples from MD Anderson, teams from UT’s engineering and life sciences schools are pinpointing weaknesses in IBC and TNBC cells. They aim to create new protein-based treatments that specifically target these vulnerabilities.
Advancements in Computer Modeling
Biomedical engineering professor Michael Sacks is leading efforts to develop a detailed computer model of the breast. This model aims to predict how a patient’s body may react to different treatments, which could significantly enhance personalized care and surgical training. Funded by the National Institutes of Health, this model will help identify tumors and improve recovery wear for patients.
The Role of Enzymes in Cancer
Research is also focusing on the enzyme APOBEC3B. While its usual job is to help fight off viruses, it can also cause mutations in cancer cells, making them harder to treat. Professor Kyle Miller and his team are exploring whether increasing the number of R-loops in cancer cells could overwhelm them with mutations, potentially leading to their destruction. Drugs that elevate R-loops have already been approved, which may allow this strategy to move into clinical use soon.
Increasing Access to Screening
While about 80% of women aged 50-74 in the U.S. have had a mammogram in recent years, that number drops for those without insurance. To address this, Dell Medical School has been offering free mobile mammograms since 2021, aiming to reach underserved communities in Central Texas. With the help of a $2 million grant, they’ll expand their services, making screenings more accessible for women who need them.
Using Technology in Treatment
Researchers are leveraging advanced computing to enhance diagnosis and treatment for breast cancer. Using patient MRI scans, Thomas Yankeelov and his team have developed mathematical models to better understand how triple-negative tumors respond to therapies. In the future, they hope that this “digital twin” approach can help predict responses to various treatments.
Additionally, researcher Ernesto Lima is optimizing treatment plans for HER2-positive breast cancer. By using simulations, his team has discovered a more effective way to administer two essential drugs, shrinking tumors significantly and reducing side effects for patients.
Revolutionizing Reconstruction
For many women, breast reconstruction after surgery can be a long and complicated process. Professor Mia Markey is working on creating custom 3D molds to streamline this process, allowing for personalized reconstruction that better suits each patient’s body. This innovation aims to improve outcomes and lower costs for patients undergoing reconstructive surgery.
A Wealth of Data
Thanks to a generous donation from cancer researchers Jim and Mitzie Wittliff, UT now has a vast collection of breast cancer data, including over 5,000 samples from various cancers. This data will provide critical insights into cancer behavior and treatment responses, further enhancing research and potentially leading to improved patient care.
Through these collaborative efforts and technological advancements, researchers at UT Austin are paving the way for innovative approaches to breast cancer treatment and care.
