Meta Analysis
Evolution and refinement of magnetically guided sentinel lymph node detection in breast cancer: meta-analysis.
Superparamagnetic iron oxide nanoparticles (SPIO) have been used as a tracer for sentinel lymph node (SLN) localization in breast cancer, demonstrating comparable performance to the combination of radioisotope (RI) and blue dye (BD). ⋯ The performance of SPIO is comparable to that of RI ± BD. Preoperative injection increases the detection rate and nodal yield, without affecting concordance. Whether skin staining and MRI artefacts are reduced by lower dose and peritumoral injection needs to be investigated.

This nationwide retrospective study was undertaken to evaluate impact of hospital volume and influence of liver transplantation activity on postoperative mortality and failure to rescue after liver surgery. ⋯ From more than 25 liver resections per year, rates of in-hospital mortality and failure to rescue declined. Management of specific postoperative complications appeared to be better in high-volume centres.
