DCISionRT provides physicians with the first radio-genomics tool to predict radiation therapy benefit.
In an independent clinical validation of DCISionRT in the landmark SweDCIS randomized clinical trial, patients with low Decision Scores no significant invasive risk reduction from radiation therapy after surgery whereas patients with elevated Decision Scores had a 9% reduction in invasive risk (HR 0.24, p=0.012). This study, for the first time, demonstrates a DCIS test that predicts the extent to which patients benefit from radiation therapy.
Results are shown are for the 196 patients treated with conserving surgery treated patients with clear margins in a multisite study. Total recurrence risks shown are adjusted for year of diagnosis. This was demonstrated in a multisite study of 474 patients1.

What information does DCISionRT give me?
Based on the biology of your DCIS, the DCISionRT test provides you and your physician the information needed to make a decision whether surgery alone or surgery with radiation therapy is appropriate.
