BACKGROUND Ideally, intraoperative sentinel lymph node (SLN) analysis in breast cancer should be automated, have high concordance with extensive histopathology, and be applicable in any hospital setting. A prospective multicentre evaluation of the one-step nucleic acid amplification (OSNA) automated molecular diagnostic system of SLN analysis was(More)
Recent advances in digital imaging have made Faxitron microradiography an attractive alternative to intra-operative conventional specimen radiography (CSR) for the excision of wire-localized breast lesions. Faxitron specimen analysis time, usefulness of digital image manipulation and re-excision rates were evaluated in comparison to CSR in 299 consecutive(More)
The expression of cyclin-dependent kinase inhibitor p27(kip1) in human tumors and normal tissues was investigated using a panel of novel anti-p27(kip1) mAbs. An inverse correlation between expression of p27(kip1) and cell proliferation was generally observed after analyzing its expression in 25 different normal human tissues. In some highly proliferative(More)
Breast cancer micrometastases in axillary lymph nodes have been detected by serial sectioning and immunohistochemistry, and shown to have prognostic significance. We have used polymerase chain reaction (PCR) to see whether we could further improve the detection rate of micrometastases. Fifty-seven axillary lymph nodes from patients with breast cancer were(More)
AIMS Prolactin plays an important role in the proliferation and differentiation of normal breast epithelium, and possibly in the development of breast carcinoma. The effects of prolactin are mediated by its receptor; thus, alteration in the expression of this receptor could be important in studying the biology of breast cancer. This investigation was aimed(More)
Patients with chronic renal failure who were undergoing dialysis were recently shown to have a low prevalence of duodenal Helicobacter (Campylobacter) pylori colonisation in spite of a high incidence of gastric metaplasia. The prevalence of the organism in the gastric antrum of 50 similar patients was estimated and compared with that in a control group(More)
PURPOSE Ser(167) was first identified as a major phosphorylation site of the estrogen receptor -alpha (ER) positive in the MCF7 breast cancer cell line. Subsequent studies have shown that Ser(167) phosphorylation is important in the regulation of ER activity and have identified p90RSK and AKT as protein kinases that phosphorylate Ser(167). The purpose of(More)
Oestrogen receptor-alpha (ERalpha) is an important prognostic marker in breast cancer and endocrine therapies are designed to inhibit or prevent ERalpha activity. In vitro studies have indicated that phosphorylation of ERalpha, in particular on serine 118 (S118), can result in activation in a ligand-independent manner, thereby potentially contributing to(More)
A cDNA library constructed from mRNA from a human breast carcinoma metastasis was screened with a polyclonal antibody to deglycosylated human milk fat globule membrane, resulting in the isolation of eight clones from a total of 10(5) plaques. One of these (J16) was identified as lactoferrin. It was highly expressed (as a 2.5 Kb mRNA) in lactating breast and(More)
Epstein-Barr virus (EBV) is associated with human B cell lymphomas, but is also commonly found in the epithelial cells of undifferentiated nasopharyngeal carcinoma. As recent reports have also suggested a wider distribution particularly in lymphoepithelioma-like carcinomas, we investigated its presence in breast carcinomas of varying histology. Using PCR(More)
