Advances in molecular biology have led to the identification of potential markers of prognostic and therapeutic importance in human cancers. HER-2 testing and targeted therapy now represents a critical cornerstone in the management of breast cancer. The objectives of the current study were to determine the frequency and prognostic significance of HER-3 over-expression and HER-4 over-expression by invasive breast cancer. ⋯ HER-3 status is an important prognostic marker of disease-specific survival in patients with invasive breast cancer. Accordingly, evaluation of the HER-3 expression level may identify a subset of patients with a poor disease prognosis, and who could undergo further evaluation for the efficacy of HER-3 targeted anticancer agents.

To determine the prognostic influence of residual tumor at or within 1 mm of the mobilization margins (R1Mobilization) compared with transection margins (R1Transection) following pancreaticoduodenectomy for pancreatic ductal adenocarcinoma (PDAC). ⋯ Following pancreaticoduodenectomy for PDAC, involvement of the transection margins in contrast to mobilization margins defines a group whose outcome is significantly worse. This may impact upon the allocation of adjuvant therapy within the setting of randomized controlled trials.

To evaluate the relationship between burnout and perceived major medical errors among American surgeons. ⋯ Major medical errors reported by surgeons are strongly related to a surgeon's degree of burnout and their mental QOL. Studies are needed to determine how to reduce surgeon distress and how to support surgeons when medical errors occur.

The goal of this study was to evaluate the effect of Roux-en-Y gastric bypass (RYGBP) on 2 metabolic disorders, diabetes and dyslipidemia, in obese type 2 diabetes mellitus (T2DM) patients. ⋯ Laparoscopic RYGBP has a beneficial effect on glucose metabolism and serum lipid composition in obese T2DM patients. Sustained weight loss was associated with maintenance of euglycemia in postoperative obese T2DM patients.
