Association of the Recurrence Score (Oncotype DX) with Local Recurrence

Online in the JCO:

The recurrence score (oncotype DX) has been an extremely valuable tool in decision making for the delivery of systemic therapy in node negative, ER+ breast cancer. The primary analyses published to date describe it's association with distant failure, survival and the relative benefit of cytotoxic chemotherapy. This article describes the association of this score with loco-regional recurrence, of upmost interest to radiation oncologists as we move to an era of personalized medicine. Perhaps not surprisingly, an association is indeed found. Of course whether radiation should be intensified somehow in the higher risk patients, or de-intensified in the lower risk patients is something that this report cannot address, but does open up the door to some potentially quite interesting clinical questions to test prospectively....
