MedicalResearch.com: What is the background for this study?
Response: Although we know that bigger surgery does not result in better patient outcomes in breast cancer, since 2005 rates of lumpectomy have been decreasing accompanied by an increase in bilateral mastectomy for unilateral cancer.
High rates of second surgery after initial lumpectomy are one deterrent for patients. In 2013 the SSO and ASTRO developed an evidence based consensus guideline endorsing no ink on tumor as the standard negative margin width for women with stage 1 and 2 cancer having breast conserving surgery with whole breast irradiation. The purpose of our study was to examine time trends in the use of additional surgery after lumpectomy before and after guideline dissemination and to determine the impact of these trends on final rates of breast conservation.
