Study Highlights Hospital's Commitment to Lifespan Research
PHILADELPHIA, June 14, 2024 /PRNewswire/ -- Researchers at
Children's Hospital of Philadelphia (CHOP) announced the discovery of a novel immune-based biomarker that could pave the way for potential lifesaving early detection of high-grade ovarian cancer (HGOC). The findings were published today in the journal Cell Reports medicine .
High-grade ovarian cancer (HGOC) is the fifth-leading cause of cancer-related death among women.
More than 90% of women are diagnosed when the disease has reached advanced stages and has already spread, presenting significant treatment challenges. Ovarian cancer is highly treatable when caught early, but tests that look for conventional biomarkers haven't been able to detect microscopic, metastatic early lesions that often develop in the fallopian tubes. However, with the discovery of a novel immune-based biomarker, there is potential to change the trajectory for many women.
Although CHOP is a pediatric environment, its comprehensive Research Institute is dedicated to improving children's lives and helping them thrive into adulthood through transformative solutions, such as new diagnostic tools, medicines, technologies, and policy recommendations. By tackling the most pressing healthcare challenges, CHOP dramatically advances wellness beyond pediatrics across the entire lifespan.
"Early detection of ovarian cancer could mean the difference between life and death for millions of women," said Bo Li , PhD, a
core faculty member in the Center for Computational and Genomic Medicine at Children's Hospital of Philadelphia. "We believe our findings can be a gamechanger, providing insights for the development of an immune-based biomarker to detect early-stage ovarian cancers, as well as helping to potentially advance pediatric cancer research."
In this study, researchers at CHOP and UT Southwestern Medical Center in Dallas analyzed T-cell receptors (TCRs) in nearly 500
blood samples from pre-diagnostic patients with ovarian cancer, as well as
healthy/benign controls from the Nurses' Health Study . TCRs are proteins found on T cells, a type of immune cell that recognizes and binds to foreign substances.
Study analysis revealed that in the early stages of HGOC, approximately two to four years before most cases of HGOC are currently diagnosed, a healthier immune system reacts significantly stronger, producing a measurable biomarker. Therefore, researchers deduced that tracking the disease within that specific timeframe, before a shift in the body's immune response, allowed for earlier treatment interventions.
The researchers also noted that additional research is needed to aid in the development of a diagnostic test sensitive enough to detect the novel immune biomarker. They envision the testing as a compliment to current approved HGOC screening protocols.
The research was supported by NCI R01 grants CA258524 and Q16 CA245318. Sample collection was partially supported by the Department of Obstetrics and Gynecology at UTSW.
