AIMS To evaluate aspects of the current practice of sentinel lymph node (SLN) pathology in breast cancer via a questionnaire based survey, to recognise major issues that the European guidelines for mammography screening should address in the next revision. METHODS A questionnaire was circulated by mail or electronically by the authors in their respective(More)
To assess the variability of oestrogen receptor (ER) testing using immunocytochemistry, centrally stained and unstained slides from breast cancers were circulated to the members of the European Working Group for Breast Screening Pathology, who were asked to report on both slides. The results showed that there was almost complete concordance among readers(More)
Controversies and inconsistencies regarding the pathological work-up of sentinel lymph nodes (SNs) led the European Working Group for Breast Screening Pathology (EWGBSP) to review published data and current evidence that can promote the formulation of European guidelines for the pathological work-up of SNs. After an evaluation of the accuracy of SN biopsy(More)
BACKGROUND The pre-operative diagnosis of primary and metastatic malignant ovarian tumors in patients treated for breast cancer is difficult. The objective of this study was to analyze and compare the characteristics and outcome of women with a history of breast cancer in order to identify pre-operative markers useful in differential diagnosis and the role(More)
Multivisceral surgical resection for cure was successfully performed in a 70-year-old man suffering from a primary hepatocellular carcinoma (HCC) associated with direct invasion to the stomach and pancreas. The patient presented with gastric outlet obstruction, upper abdominal pain and a history of chronic liver disease due to hepatitis B virus (HBV)(More)
INTRODUCTION The expression of E-cadherin, beta-catenin and topoisomerase II has been associated with clinical outcome of several cancers including sarcomas. We aimed to evaluate the expression of these markers in leiomyosarcomas (LMS). MATERIALS AND METHODS Paraffin blocks of 19 primary, nonmetastatic LMS were analysed immunohistochemically for the(More)
The present study assessed the immunohistochemical expression of ras p21 oncoprotein in 41 cases of benign and cancerous lesions of the prostate gland and correlated p21 expression with survival of patients operated for prostate cancer. Our results show that p21 is detected in both categories of patients, the expression being weak in adenomatous hyperplasia(More)
Two groups (group A = 25 cases and group B = 34 cases) of vulvar cancer patients, treated with a modified "butterfly" operation (MBO = group A) and a triple incision (TI = group B) technique, were evaluated retrospectively. The aim was to compare the two operative methods, regarding perioperative morbidity and clinical outcome. The histopathologic and(More)
We examined the expression of ras p21 oncoprotein using monoclonal antibody Y13 259 and applied the streptavidin-biotin method. A total of 79 imprints of breast lesions were taken during frozen section. Our purpose was evaluation of the staining intensity, at the cellular level, without the technical disadvantages of formalin-fixed, paraffin-embedded(More)
A detailed analysis of the consistency with which pathologists from 12 different European countries diagnose and classify breast disease was undertaken as part of the quality assurance programme of the European Breast Screening Pilot Network funded by the Europe against Cancer Programme. Altogether 107 cases were examined by 23 pathologists in 4 rounds.(More)
