The impact of palliative resection of the primary tumor on outcomes in patients with metastatic colorectal cancer (mCRC) remains unclear. The primary objective of this study was to evaluate the association between palliative resection and overall survival (OS) in a population-based cohort of mCRC. ⋯ In this cohort of mCRC patients, palliative resection of the primary tumor was associated with improved OS.

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.

While human epidermal growth factor receptor 2 (HER2) overexpression is an adverse breast cancer prognostic factor, it is unclear whether there are differences in outcomes between types of local treatment in this population. This retrospective study examined locoregional recurrence and survival in women with node-negative, HER2+ breast cancer treated with breast-conserving therapy (BCT) versus mastectomy. ⋯ BCT is safe in the population of women with pT1-2, N0, HER2+ breast cancer, providing high rates of locoregional control and survival equivalent to mastectomy. Trastuzumab was associated with improved survival in both groups.

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.
