Catalytic Nanomedicine offers new Hope for Brain Tumor Patients
Mexico City – A revolutionary approach to treating malignant brain tumors, known as catalytic nanomedicine, is gaining momentum thanks to the pioneering work of Dr. Tesy María López Goerne. Her research, presented recently at the Faculty of medicine of the National Autonomous University of Mexico (UNAM), details a method that targets cancer cells with unprecedented precision, offering a potential option to conventional chemotherapy.
The Promise of Nanomedicine
Nanomedicine, the submission of nanotechnology to medical treatment, operates on an incredibly small scale – between 1 to 100 nanometers [2].To put that into perspective,a human hair is approximately 80,000 nanometers wide. This allows for targeted drug delivery and innovative therapies, as explained by WebMD [1]. Dr. López Goerne’s work specifically focuses on catalytic nanomedicine, a cutting-edge field within this discipline.
A Personal Mission drives Innovation
Dr. López Goerne,a professor at the Metropolitan Autonomous University,Xochimilco Unit,shared a deeply personal motivation behind her dedication to cancer research. Having lost both her father and mother to the disease, and having battled cancer herself seven times, she described her work as a profound mission. “I am totally married to cancer… surely I have a very critically important mission as I am here,” she stated during her presentation.
Breaking from Traditional Chemotherapy
dr. López goerne and her team challenged the conventional approach of chemotherapy, recognizing it’s damaging effects on healthy cells. Instead of a broad-spectrum attack, they developed a “nanobiocatalyzing” system. This innovative method utilizes nanoparticles to specifically target the DNA of tumor cells, disrupting their critical nitrogenous base links without harming surrounding healthy tissue. [3] defines nanomedicine as the use of nanomaterials for the diagnosis,monitoring,control,prevention and treatment of diseases.
Did You Know? Traditional chemotherapy often damages healthy cells alongside cancerous ones, leading to debilitating side effects. Nanobiocatalysis aims to eliminate this collateral damage.
Remarkable Results in Preclinical Trials
Early results from animal models have been remarkably promising. The nanobiocatalyzing treatment achieved an 85% reduction in tumor size,significantly outperforming Cisplatino,a standard chemotherapy drug,which achieved only a 30% reduction.Crucially, the catalyst demonstrated a lack of the adverse side effects commonly associated with traditional chemotherapy.
| Treatment | Tumor Reduction (Animal Models) | Side Effects |
|---|---|---|
| Nanobiocatalyzing | 85% | None Reported |
| Cisplatino | 30% | Notable |
The Role of artificial Intelligence
Dr. López Goerne also highlighted the crucial role of artificial intelligence (AI) in both diagnosing and treating brain tumors. AI algorithms, especially those employing “Deep Learning,” can precisely delineate tumor boundaries and differentiate them from healthy brain tissue, enabling more accurate surgical planning. AI also aids in the early detection of tumor recurrence through the analysis of biomarkers in blood or cerebrospinal fluid.
Pro Tip: AI isn’t meant to replace doctors, but to augment their abilities, providing them with more precise data and tools for better patient care.
However, Dr. López Goerne emphasized that technology should not overshadow the importance of the doctor-patient relationship. “They will not be able to treat the patient with artificial intelligence.They have to face their patient and know him, know who he is. Each patient is an individual, he is unique.”
Patient Success Stories
The presentation featured inspiring stories of patients who have benefited from this innovative treatment. One case involved a Canadian patient with glioblastoma and five metastases who, after receiving the nanobiocatalyzing treatment, regained the ability to walk and speak, and lived for five years, witnessing his children grow up. Additionally,ten children in palliative care at the Children’s Hospital of Mexico Federico Gómez,who received the experimental treatment,remain alive,with some surviving for over seven years.
Future Directions
Dr. López Goerne’s team is currently developing a new generation of nanobiocatalyzers designed to target not only DNA but also lipids and genes associated with tumor growth. Clinical trials are anticipated to begin in 2026.
What challenges do you foresee in translating these promising preclinical results into widespread clinical application?
The scientific and humanitarian contributions of Dr. López Goerne were met with resounding applause, underscoring the potential of combining technological innovation with compassionate patient care.
The Future of Nanomedicine
Nanomedicine is a rapidly evolving field with the potential to revolutionize healthcare. Beyond cancer treatment, nanomedicine is being explored for applications in drug delivery, regenerative medicine, and diagnostics. The development of more sophisticated nanoparticles and targeted therapies promises to improve treatment outcomes and reduce side effects for a wide range of diseases. The convergence of nanomedicine with artificial intelligence is expected to accelerate these advancements, leading to personalized and precision medicine approaches.
