Comparative Study
International rates of breast reconstruction after prophylactic mastectomy in BRCA1 and BRCA2 mutation carriers.
Breast reconstruction is an option for women with BRCA1 or BRCA2 mutations who elect to undergo prophylactic mastectomy to prevent breast cancer. We report on the uptake of breast reconstruction after prophylactic mastectomy in women with BRCA mutations from eight countries. ⋯ The majority of women elect for breast reconstruction after prophylactic mastectomy. However, younger women and those without a previous diagnosis of breast cancer are more likely to have breast reconstruction than older women or those with a previous diagnosis of cancer.

Intraductal papillary mucinous neoplasms (IPMNs) are the most common cystic precursor lesions of invasive pancreatic cancer. The recent identification of activating GNAS mutations at codon 201 in IPMNs is a promising target for early detection and therapy. The purpose of this study was to explore clinicopathological correlates of GNAS mutational status in resected IPMNs. ⋯ GNAS activating mutations can be reliably detected in IPMNs by pyrosequencing. In terms of clinicopathological parameters, only histological subtype was correlated with mutational frequency, with the intestinal phenotype always associated with GNAS mutations.

Comparative Study
Usefulness of stroke volume index obtained with the FloTrac/ Vigileo system for the prediction of acute kidney injury after radical esophagectomy.
To assess the impact of stroke volume index (SVI) at the end of esophagectomy upon postoperative renal function. ⋯ Low SVI at the end of esophagectomy may represent a risk factor for AKI in the early postoperative period. Further studies are required to examine whether maintaining SVI above 35 ml/m2 reduces the incidence of AKI after esophagectomy.

Complex, oncologic surgery is an important component of resident education. Our objective was to evaluate the impact of resident participation in oncologic procedures on overall 30-day morbidity and mortality. ⋯ Trainee participation in complex, oncologic surgery is associated with significantly higher rates of 30-day postoperative complications in NSQIP-participating hospitals; however, this effect is countered by overall lower 30-day mortality and improved rescue rate in preventing death among patients suffering complications.

Comparative Study
Cost-effectiveness of minimally invasive versus open esophagectomy for esophageal cancer.
A recent randomized trial comparing minimally invasive (MIE) and open esophagectomy for esophageal cancer reported improved short-term outcomes. However, MIE has increased operative costs, and it is unclear whether the short-term benefits of MIE outweigh the increased operative costs. Therefore, the objective of this study was to determine the cost-effectiveness of MIE compared to open esophagectomy for esophageal cancer. ⋯ MIE is cost-effective compared to open esophagectomy in patients with resectable esophageal cancer.
