Recurrence rates for MammoSite vs. 3D Conformal?

Page last modified on: November 20, 2008
Question from Aliceb: How do the recurrence rates for MammoSite Radiation and 3D Conformal Radiation compare at this point in the clinical trials for each?
Answer —Generosa Grana, M.D., F.A.C.P.: The trial that is currently ongoing comparing whole breast conformal radiation to MammoSite has not completed accrual and is still ongoing, so no data is available from this national trial. There is data from smaller institutional trials with limited follow-up, suggesting that MammoSite has good effectiveness at preventing recurrence of cancer in the breast and has good cosmetic outcomes. For now, multiple organizations have suggested that it is imperative that this trial be completed and that patients whenever possible be enrolled on this trial, so that the data will become available.
