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.

Oncoplastic surgical techniques offer an option of breast conserving surgery for larger tumors with the use of glandular reshaping to prevent postoperative deformity. A technique for the excision of lower inner quadrant tumors via a V incision is described, the lower-inner quadrant-V (LIQ-V) mammoplasty, and the results of a pilot study are reported. ⋯ The deformity often associated with tumors of the LIQ is adequately addressed by this new technique. It has a complication rate comparable to other mammoplasty series and a high rate of clear resection margins. Many oncoplastic surgery techniques are based on inverted T mammoplasty, but these are not suited for all tumor locations. The LIQ-V mammoplasty is an adaptation of the standard techniques that best suit the LIQ. It is oncologically safe and provides disease-free margins, and although the resection volumes are large, the cosmetic outcome is not compromised.
