Diagnosis / Prognosis - DCISionRT Test

Ductal Carcinoma In Situ (DCIS) - Patients must have histologically confirmed ductal carcinoma in situ (DCIS) in a single breast without evidence of invasive cancer (presence of lobular carcinoma in situ (LCIS) or other benign breast disease in addition to DCIS is acceptable).


Diagnosis / Prognosis: DCISionRT Test
The Prelude DCISionRT Test was developed by Prelude Corporation and is performed at its CLIA laboratory facility. The biomarkers used to evaluate the biologic signature of DCIS tissue are based on over a decade of research including the University of California, San Francisco, Yale University as well as Prelude Corporation. The test is prognostic for 10-year recurrence risk and predicts RT treatment benefit for invasive breast cancer. The laboratory is regulated under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) as qualified to perform high-complexity clinical testing and is accredited by the College of American Pathologists (CAP).

Summary
Brief summary
This is a prospective cohort study for patients diagnosed with ductal carcinoma in situ
(DCIS) of the breast. The primary objective of the study is to create a de-identified
database of patients, test results, treatment decisions and outcomes that can be queried to
determine the utility of the DCISionRT™ test in the diagnosis and treatment of ductal
carcinoma in situ of the breast.
