LAGUNA HILLS, Calif., Nov. 16, 2022 /PRNewswire/ -- Prelude Corporation (PreludeDx™), a leader in molecular diagnostics and precision medicine for early-stage breast cancer, announced today that data will be presented in four separate poster presentations at the 2022 San Antonio Breast Cancer Symposium (SABCS), to be held on December 6 – 10, 2022 at the Henry B. Gonzalez Convention Center in San Antonio, TX. Presentations will include a spotlight poster on DCISionRT and its identification of a low-risk group of DCIS patients with no benefit from adjuvant radiation, a poster addressing the role of DCISionRT in treatment implications for HER2(+) patients, and two separate presentations on the latest data in the Predict Registry studies from both the U.S. and Australia.

"We are pleased with how broadly our DCISionRT biosignature is being utilized and are excited to present this latest data at the prestigious SABCS," said Dan Forche, President and CEO of PreludeDx. "We remain committed to continual improvement of personalized medicine for early-stage breast cancer patients and their clinicians."

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.
