PreludeDx™ presents new data demonstrating utility of DCISionRT® to de-escalate radiation therapy for women with DCIS (PreludeDx Press Release)
"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."

PreludeDx to Present New Data on the Clinical Utility of DCISionRT in Australian Patients with DCIS at the 2023 San Antonio Breast Cancer Symposium (GlobeNewswire)
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. The poster...demonstrates that the use of DCISionRT resulted in significant changes in recommendations to add or omit RT compared to clinicopathologic factors (CP) alone. Specifically, in the interim analysis of 483-patients treated with breast conserving surgery in Australia, the use of the test resulted in a 41% change in RT recommendations and a 9% change in hormone therapy (HT) recommendations."

PreludeDx to Present Data for a Novel Molecular Biosignature to Predict Radiation Therapy Benefit in Early-Stage Invasive Breast Cancer at the 2023 San Antonio Breast Cancer Symposium (GlobeNewswire)
P=NA | N=NA | "Prelude Corporation...announced it will be presenting data on a novel biosignature that predicts radiation therapy (RT) benefit in invasive (Stage I, II) breast cancer patients. 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....While RT following breast conserving surgery was associated with a reduction for recurrence rates (HR=0.3, 95%CI [0.1, 0.5], p<0.001) in the overall patient population, in multivariable analysis, the biosignature was predictive for RT benefit adjusted for clinicopathologic factors, where patients identified as 'Residual-Risk' by the biosignature had a higher ipsilateral breast recurrence rate after RT compared to other risk groups with a positive interaction with RT (HR=3.7 95%CI [1.6,8.7], p=.0026)."
