Since the emergence of breast conserving surgery (BCS) as an alternative to mastectomy in the 1980's, there has been little consensus on what constitutes acceptable margins for cases of invasive breast cancer, how best to evaluate margins in the operating room, or an understanding of the challenging process of margin assessment by pathologists. The program committee for the 15th Annual Meeting of The American Society of Breast Surgeons organized a plenary session to discuss the latest thinking and guidelines for these important issues. The SSO/ASTRO Consensus Guideline on Margins for BCS was an important focus of discussion. ⋯ The College of American Pathologists protocols for breast specimen margin evaluation consider multiple variables that can impact the proper assessment of margins. These variables include: tissue fixation time, specimen orientation, cold ischemia time, leaking ink, specimen pancaking and others that surgeons need to be aware of. Determining when "enough is enough" should not only be the application of guidelines and national standards, but also a multidisciplinary discussion between breast cancer specialists for what is right for the individual patient's unique circumstances.

Embracing national cancer registries for improved care of rare tumors.

Mastectomy is associated with postoperative nausea and pain. We evaluated whether paravertebral block (PVB) use altered opioid use, antiemetic use, and length of stay in patients undergoing mastectomy. ⋯ PVB results in decreased opioid use and decreased need for postoperative antiemetic medication in patients undergoing mastectomy. The greatest benefit is seen in patients undergoing bilateral mastectomy with immediate breast reconstruction.

Availability of immediate breast reconstruction (IBR) varies among institutions, yet the impact of IBR availability on the rates of bilateral mastectomy (BM) versus unilateral mastectomy (UM) for breast cancer is unknown. ⋯ In this analysis of national data, BM rates were higher in hospitals where IBR was available, suggesting a significant influence of institutional factors on treatment options for breast cancer patients. Efforts are needed to ensure patients have access to IBR when desired and to better understand the reasons for hospital variation in BM rates.

Comparative Study
Localizing high-risk lesions for excisional breast biopsy: a comparison between radioactive seed localization and wire localization.
Improved resolution and utilization of screening breast imaging has increased identification of nonpalpable high-risk lesions (HRL) and subsequent excisional breast biopsies (EBBs). Wire localization (WL), used most commonly for EBBs, may have shortcomings, including wire displacement, patient discomfort, limitations with incision planning and scheduling logistics. Radioactive seed localization (RSL) may overcome these drawbacks. The purpose of this study was to compare WL and RSL for EBBs for HRLs. ⋯ RSL is comparable to WL for EBB of HRLs with similar OR times and upstage rates. SV is significantly decreased with RSL and may translate into improved cosmetic outcomes without sacrificing the diagnostic accuracy of the EBB.
