Sentinel lymph node (SLN) biopsy is an accurate method for the detection of axillary metastases in early breast cancer patients and is of value as a replacement for axillary dissection. However, variations in the methods and protocols used for the pathological evaluation of SLN exist in everyday practice. Therefore, standardization how to detect, dissect, process, stain, assess and report SNL is required in order to stratify patients into adequate prognostic groups. The aim of this study was to present our experience in SLN analysis in patients with early breast cancer and clinical stage T1-2 and N0. In the period between 2003 and 2011, 1071 consecutive patients or 1915 SLN were analyzed. The protocol included intraoperative analysis of histological frozen sections and cytological imprint, followed by analysis of paraffin sections according to the protocol that included sections of whole SLN with the interval of 250 prm. According to the accepted protocol 75% of SLN were negative. The obtained results were correlated with literature data.

As a promising candidate for tackling drug-resistant cancers, triptolide, a diterpenoid derived from the Chinese medicinal plant Tripterygium wilfordii, has been developed. This review summarizes potential antitumor activities, including the suppression of RNA polymerase II, the suppression of heat shock proteins (HSP70 and HSP90), and the blockade of NF-kB signalling. Triptolide is the first known compound to target cancer cells specifically but spare normal cells, and it has success in treating cancers that are difficult to treat, including pancreatic, breast, and lung cancers.

Background: Whilst it is inconvenient and time-intensive, predominantly (PP) and exclusively pumping (EP) mothers rely on breast expression to provide milk for their infants and to ensure continued milk supply, yet these populations are poorly understood.
Methods: We assessed and characterised Western Australian PP mothers ( = 93) regarding 24 h milk production (MP) and infant milk intake and demographics, perinatal complications and breastfeeding difficulties, the frequencies of which were compared with published general population frequencies. Pumping efficacy and milk flow parameters during a pumping session in PP mothers ( = 32) were compared with those that pump occasionally (reference group, = 60).
Changes in the Microcirculation and Physiologic Perfusion Dynamics of Free DIEP Flaps in the First 72 h After Breast Reconstruction.

The autologous reconstruction of the female breast using a microsurgical DIEP flap is a reliable and safe method. To detect impairments early and preserve the microvascular flap through timely revision, a better understanding of physiologic perfusion dynamics is necessary. This exploratory study examines changes in microcirculation in free DIEP flaps within the first 72 h after vascular anastomosis using laser Doppler flowmetry and white-light spectrophotometry.

Sentinel lymph node (SLN) detection has been widely investigated in recent years as a part of the surgical staging of women with endometrial cancer (EC), gradually overtaking lymphadenectomy (LND) in this respect. In this study, thirty EC patients, assumed as stage I, were investigated using superparamagnetic iron oxide (SPIO) as a tracer for SLN detection followed by LND. The endpoints of this research were the proportion of successful SLN detection, the average number of SLNs per patient, the percentage of bilaterally detected SLNs, and the proportion of metastatic SLNs.
