TL;DR: The Expert Panel continues to recommend ER testing of invasive breast cancers by validated immunohistochemistry as the standard for predicting which patients may benefit from endocrine therapy, and no other assays are recommended for this purpose.
Journal ArticleDOI
Society of surgical oncology-American Society for Radiation Oncology consensus guideline on margins for breast-conserving surgery with whole-breast irradiation in stages i and II invasive breast cancer
Meena S. Moran,Stuart J. Schnitt,Armando E. Giuliano,Jay R. Harris,Seema A. Khan,Janet K. Horton,Suzanne Klimberg,Mariana Chavez-MacGregor,Gary M. Freedman,Nehmat Houssami,Peggy L. Johnson,Monica Morrow +11 more
TL;DR: The use of no ink on tumor as the standard for an adequate margin in invasive cancer in the era of multidisciplinary therapy is associated with low rates of IBTR and has the potential to decrease re-excision rates, improve cosmetic outcomes, and decrease health care costs.
