ASTRO 2023 Logo
LAGUNA HILLS, Calif., Sept. 19, 2023 (GLOBE NEWSWIRE) — 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 identify limitations in current clinicopathologic factors alone to predict radiation benefit in women with ductal carcinoma in situ (DCIS). This comparison data was selected for a scientific session oral presentation at the 65th Annual American Society for Radiation Oncology (ASTRO) Meeting, to be held on October 1-4, 2023 at the San Diego Convention Center, San Diego, CA.
“We are pleased to have our new comparison data on DCISionRT selected for oral presentation at the prestigious ASTRO Annual Meeting,” said Dan Forche, President and CEO of PreludeDx. “This new data is being presented by Dr. Frank A. Vicini, who will share how this data further validates the value of DCISionRT in guiding treatment decisions for DCIS patients.”

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.
