PreludeDx™ to Present Comparative Analysis of Treatment Recommendations of Black and White DCIS Breast Cancer Patients Using DCISionRT® at ASBrS 2023 Annual Meeting

Prelude Corporation (PreludeDx™), a leader in molecular diagnostics and precision medicine for early-stage breast cancer, today announced it will be presenting data using DCISionRT^® to examine the decision impact on physician recommendation for adjuvant radiation therapy by race (White vs. Black) in women with ductal carcinoma in situ (DCIS) enrolled in the PREDICT study. This race/ethnicity data will be presented at the 24^th Annual Meeting of the American Society of Breast Surgeons (ASBrS), being held on April 26 – 30, 2023 at the John B. Hynes Veterans Memorial Convention Center in Boston, Massachusetts.

Poster Presentation
Title: A Comparative Analysis of Changes in Treatment Recommendations for Black and White Patients with Ductal Carcinoma in Situ Using a 7-gene Predictive Biosignature: Analysis of the PREDICT Study 
Presenter: Pat Whitworth, MD, FACS, FSSO, Director of the Nashville Breast Center
Date: Friday, April 28, 6:15 PM – 7:30 PM

“While there is a significant body of evidence addressing race/ethnic treatment differences among women with invasive breast cancer, there is limited evidence for DCIS. We are excited to present this new and valuable data for DCIS patients,” says Dan Forche, President and CEO of PreludeDx. “We are confident that the new DCISionRT data will help guide physicians and their patients to make more informed treatment decisions.”

About DCISionRT for Breast DCIS

DCISionRT is the only risk assessment test for patients with ductal carcinoma in situ (DCIS) that predicts radiation therapy benefit. Patients with DCIS have cancerous cells lining the milk ducts of the breast, but they have not spread into surrounding breast tissue. In the US, over 60,000 women are newly diagnosed with DCIS each year. DCISionRT, developed by PreludeDx on technology licensed from the University of California San Francisco, and built on research that began with funding from the National Cancer Institute, enables physicians to better understand the biology of DCIS. DCISionRT combines the latest innovations in molecular biology with risk-based assessment scores to assess a woman’s individual tumor biology along with other pathologic risk factors and provide a personalized recurrence risk. The test provides a Decision Score^™ that identifies a woman’s risk as low or elevated. Unlike other risk assessment tools, the DCISionRT test combines protein expression from seven biomarkers and four clinicopathologic factors, using a non-linear algorithm to account for multiple interactions between individual factors in order to better interpret complex biological information. DCISionRT’s intelligent reporting provides a woman’s recurrence risk after breast conserving surgery alone and with the addition of radiation therapy. In turn, this new information may help patients and their physicians to make more informed treatment decisions.
