Newswise — DALLAS – Feb. 08, 2023 – Utilizing artificial intelligence (AI) along with traditional pathology offers promise for swiftly developing treatment plans for patients with non-small cell lung cancers, a team led by UT Southwestern Medical Center researchers discovered.
“We found that combining digitized clinical pathology slides with AI algorithms holds the potential to improve precision treatment of cancer patients,” said Yang Xie, Ph.D., Professor in UTSW’s Peter O'Donnell Jr. School of Public Health and in the Lyda Hill Department of Bioinformatics, and Associate Dean of Data Sciences at UTSW Medical School.
The findings, published in The Journal of Clinical Investigation, identified lung cancers most likely to respond to one common treatment. They focused on metastatic non-small cell lung cancers from 272 patients with the epidermal growth factor receptor (EGFR) gene mutation who were enrolled in studies conducted by the Lung Cancer Mutation Consortium (LCMC). The consortium comprises more than 20 U.S. cancer centers that match patients with drugs and clinical trials targeting cancers of the chest area.
Dr. Xie, also founding Director of the Quantitative Biomedical Research Center at UTSW, and Guanghua “Andy” Xiao, Ph.D., Professor of Bioinformatics and in the O’Donnell School of Public Health, are corresponding authors on the study. Drs. Xie and Xiao are members of the Harold C. Simmons Comprehensive Cancer Center.
Dr. Xie said tyrosine kinase inhibitors (TKIs) are effective drugs for many patients with tumors that contain EGFR mutations, but some tumors are unresponsive. The researchers’ goal was to find a way to determine tumor characteristics that predict responsiveness to this treatment.
“By studying interactions between tumor cells and cells in the microenvironment that surround tumors, we found an important marker that could predict which metastatic cancers would show resistance to TKIs,” Dr. Xie said.
The work builds on an AI-based computational algorithm previously developed by the study’s first author, Shidan Wang, Ph.D., Assistant Professor in the O’Donnell School of Public Health.
The team’s integrated analysis identified potential mechanisms of resistance to EGFR-targeted therapy, suggesting potential alternative treatments for TKI-resistant tumors and a direction for future studies.
Other UTSW researchers who contributed to the study include Ruichen Rong, Donghan M. Yang, Justin A. Bishop, Shirley Yan, Ling Cai, and John Minna.
Dr. Bishop holds the Jane B. and Edwin P. Jenevein, M.D. Distinguished Chair in Pathology. Dr. Minna holds the Max L. Thomas Distinguished Chair in Molecular Pulmonary Oncology and the Sarah M. and Charles E. Seay Distinguished Chair in Cancer Research. Dr. Xiao holds the Mary Dees McDermott Hicks Chair in Medical Science. Dr. Xie holds the Raymond D. and Patsy R. Nasher Distinguished Chair in Cancer Research, in Honor of Eugene P. Frenkel, M.D.
