Multicenter Study
Sentinel node biopsy using a magnetic tracer versus standard technique: the SentiMAG Multicentre Trial.
The SentiMAG Multicentre Trial evaluated a new magnetic technique for sentinel lymph node biopsy (SLNB) against the standard (radioisotope and blue dye or radioisotope alone). The magnetic technique does not use radiation and provides both a color change (brown dye) and a handheld probe for node localization. The primary end point of this trial was defined as the proportion of sentinel nodes detected with each technique (identification rate). ⋯ The magnetic technique is a feasible technique for SLNB, with an identification rate that is not inferior to the standard technique.

Comparative Study
Radioactive iodine remnant uptake after completion thyroidectomy: not such a complete cancer operation.
Given limitations in preoperative diagnostics, thyroid lobectomy followed by completion thyroidectomy (CT) for differentiated thyroid cancer (DTC) may be required. It is unclear whether resection quality by CT differs from that by total thyroidectomy (TT). Additional surgeon or patient factors may also influence the "completeness" of resection. This study evaluated how CT and surgeon volume influence the adequacy of resection as measured by radioactive iodine (RAI) remnant uptake. ⋯ Single-stage TT provides a better resection based on smaller thyroid remnant uptakes than CT for patients with thyroid cancer. If a staged operation for cancer is necessary, surgeon volume may affect the completeness of resection.

The development of breast lymphedema (BLE) after breast/axillary surgery is poorly characterized. We prospectively evaluated clinical and surgical factors associated with development of BLE. ⋯ Risk of BLE is primarily related to performance of any axillary surgery but not the extent of axillary surgery or number of lymph nodes removed. Other factors associated with BLE were increased body mass index, incision location, and prior surgical excisional biopsy.

Management of peritoneal disseminated gastric cancer (GC) remains a challenging problem. The purpose of our study was to evaluate the outcome of bidirectional induction chemotherapy [bidirectional intraperitoneal and systemic induction chemotherapy (BIPSC)] in patients with peritoneal carcinomatosis (PC) arising from GC who underwent cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). ⋯ As a viable option, BIPSC with CRS and HIPEC for patients with PC arising from GC may be performed safely, with acceptable morbidity and mortality, in a specialized unit. Response to BIPSC, optimal CRS and limited peritoneal dissemination seem to be essential to achieve the best outcomes in these patients.

The objective of this study was to determine the success rate and complications of using the percutaneous approach of the external jugular vein (EJV) for placement of a totally implantable venous-access port (TIVAP) with a preoperative estimate of the detailed anatomical orientation of the cervical venous plexus using computed tomography venography (CT-V). ⋯ The percutaneous EJV approach with CT-V guidance is an optional method for patients with multiple central venous cannulations, those in hemodialysis, or those with long catheter indwelling periods.
