JERUSALEM, ISRAEL – The Hadassah Cancer Research Institute (HCRI) has achieved a major breakthrough in personalized cancer care: the development of a neural embedding model that uses machine learning, a kind of artificial intelligence (AI), as well as natural language processing (NLP) to detect dominant mutational signatures in targeted gene panels using only a few mutations, making it ideal for everyday clinical use. The research that led to the new model, called MESiCA for “mutational embeddings for signatures identification in clinical assays,” is descried in Cell Reports Medicine.
“MESiCA represents a major leap forward in personalized medicine,” said Dr. Michal Lotem, head of HCRI. “This innovative model offers a practical tool for oncologists, enabling them to make more informed decisions, ultimately leading to improved patient outcomes.”
The Hadassah Cancer Research Institute is the transitional research arm for oncology for the Hadassah Medical Organization, a leading teaching and research hospital system in Jerusalem.
Unlocking the Potential of Mutational Signatures
Cancer development is driven by mutations in DNA that leave behind so-called mutational signatures, i.e., unique patterns that act as fingerprints, revealing the underlying causes of the cancer. Some of these fingerprints have clinical implications for treatment plans. Traditionally, identifying these signatures has required analyzing a vast amount of data, often exceeding what is available in routine clinical settings.
“Current methods rely on targeted gene panel testing, which only analyzes a small portion of the genome,” said Dr. Aron Popovtzer, head of Hadassah’s Sharett Institute of Oncology, which works in partnership with HCRI. “This limitation has hindered our ability to detect mutational signatures and apply this information to personalize treatment plans.”
MESiCA: A Game-Changer for Personalized Care
Said Dr. Shai Rosenberg, Senior Neuro-Oncologist, head of Hadassah’s Laboratory for Cancer Computational Biology and the study’s principal investigator, “MESiCA has been validated in over 60,000 cancer samples, revealing crucial signatures linked to better survival rates and treatment responses.”
Added Dr. Adar Yaacov, the study’s lead author, “By enabling the detection of these signatures in routine tests, MESiCA empowers clinicians to prescribe more accurate personalize treatment plans, ultimately improving patient outcomes.”
This groundbreaking research paves the way for a new era of personalized cancer care. With MESiCA, the Hadassah Cancer Research Institute continues to demonstrate its commitment to developing innovative solutions to combat cancer.
