PreludeDx

"Prelude Corporation (PreludeDx™)...presented data on the use of DCISionRT® to identify a subset of patients with high-risk clinicopathology who had a low 10-year risk of in-breast recurrence (IBR) and no significant benefit from radiation therapy (RT). In contrast, patients who had both high risk DCISionRT and high-risk clinicopathology had high 10-year IBR rates and significant RT benefit. The data was presented at the 25th American Society of Breast Surgeons (ASBrS) Annual Meeting, held on April 10 – 14, 2024 at the Orlando World Center Marriott."

P=NA | N= 483 | "Prelude Corporation...announced it will present data demonstrating the decision impact on physician recommendations for radiation therapy (RT) in ductal carcinoma in situ (DCIS) patients in Australia. The data will be presented at the 2023 San Antonio Breast Cancer Symposium (SABCS), held on December 5 - 9, 2023 at the Henry B. Gonzalez Convention Center, San Antonio, Texas.
