BACKGROUND Proper preoperative staging is vital in the treatment of breast cancer patients. The aim of our study was to assess the value of the diagnostic information provided by PET/CT in surgical practice in breast cancer cases considered early-stage by conventional diagnostic modalities. METHODS Whole-body 18-FDG PET/CT was performed on 115 breast(More)
INTRODUCTION Hereditary Non-polyposis Colorectal Carcinoma is the most frequent genetic disease leading to colon and other malignancies. Recognizing the condition requires extensive family history going back several generations focusing particularly on the types of tumors occurring in the family at different age groups. METHODS In families who met the(More)
AIM To screen a suspected Hungarian HNPCC family to find specific mutations and to evaluate their effect on the presentation of the disease. METHODS The family was identified by applying the Amsterdam and Bethesda Criteria. Immunohistochemistry was performed, and DNA samples isolated from tumor tissue were evaluated for microsatellite instability. The(More)
The Bethesda guidelines may offer more useful criteria in patients’ selection for germline mismatch repair gene mutation analysis than guidelines merely based on family background. An early onset double primary colorectal cancer patient with poor family history with MSI-H status was investigated for MLH1 promoter methylation, expression of the MLH1 and MSH2(More)
Hereditary Nonpolyposis Colorectal Carcinoma (HNPCC) is the most frequent inherited disease which can lead to the development of tumors in the colon and other locations. Its genetic basis is related to the germline mutation of the Mismatch Repair (MMR) genes. Muir-Torre syndrome is considered one of the subtypes of this disease, in which the HNPCC tumor(More)
Lynch syndrome (Hereditary nonpolyposis colorectal cancer, HNPCC) is an inherited disease with variable phenotype causing the development of colon cancer and other malignancies. The basis of the disease is believed to be the mismatch repair gene mutations. Genetic screening has been performed among the patients who have undergone surgery for colon cancer at(More)
β-catenin and E cadherin are both membrane-associated proteins which are essential regulators and providers of cellular adhesion. In the metastatic cascade of malignant tumours, detachment of tumour cells from each other is a very important step. It has been shown in several tumour types, that reduced expression of these proteins is important. The aim of(More)
BACKGROUND In acute myeloid leukemia (AML), the internal tandem duplication (ITD) in the juxtamembrane domain of the FLT3 (Fms-like tyrosine kinase 3) gene is one of the most frequent genetic alterations associated with poor prognosis. METHODS A complex evaluation of the analytical properties of the three most frequently used detection methods--PCR(More)
BACKGROUND/AIMS To examine the clinical and protein expression characteristics of tumor tissues for prediction of prognosis in colorectal cancer (CRC). METHODOLOGY We retrospectively analyzed the clinicopathological data of patients with stage T3N0 CRC, operated between 1997-2003 and the surgical materials for the relation between disease prognosis and(More)
INTRODUCTION Secondary bladder neoplasms are uncommon and they represent only 2% of all malignant bladder tumors. CASE PRESENTATION The authors present a case of a 59-year-old Caucasian man with a primary gastric adenocarcinoma that had been surgically removed 10 years before he developed bladder metastasis. He presented with low abdominal pain after 10(More)
