53 Initial results of a canadian feasibility study of accelerated partial breast irradiation (APBI) using 3-D conformal radiation therapy (3D CRT)

Does a Three-Field Electron/Minitangent Photon Technique Offer Dosimetric Advantages to a Multifield, Photon-Only Technique for Accelerated Partial Breast Irradiation?

“…The contouring of the target volumes followed previously defined guidelines, 6 which have been applied in the RAPID trial and a prospective Canadian pilot 3D-CRT APBI trial with promising 2-year results. 7,8 Subjects were treated with APBI using a 4 or 5 field, noncoplanar, photon-only technique. The photon energy used was 6 MV or a combination of 6 plus 18 MV.…”
