Sensitivity, specificity and correlations among several biomarkers for monitoring occupational exposure to complex mixtures of genotoxic agents were assessed in occupational environments in Hungarian study populations. The studies have been focused on DNA adduct formation, urinary metabolites, mutations and micronuclei induced by exposures to complex(More)
BACKGROUND/AIMS Human papilloma virus (HPV) infection in esophageal cancer cases has been found in 0-70%, depending on different methods and geographical variances. Complete pathological response has been found in 30% of cases after neoadjuvant chemo-radiation (CRX). The aim of this study was to discover a possible relation between HPV-infection and(More)
BACKGROUND Preoperative radio-chemotherapy (RCX) was introduced to improve the outcome of patients with oesophageal cancer (EC), but conflicting results have been released. Some 20-30% of patients show a complete pathological response, however, the perioperative morbidity and mortality is increased. To search for factors indicating response prior to the(More)
A subunit vaccine in the form of immunostimulating complex (iscom) was prepared to contain the envelope glycoproteins of bovine herpesvirus type 1 (BHV-1). This iscom preparation was tested in a vaccination experiment on 4-month-old calves seronegative to BHV-1. In this experiment, four groups with three animals per group were used. Two groups were(More)
BACKGROUNDS/AIMS The present study was designed to provide an analysis of factors for tumor vascularisation and proliferation in 37 rectal cancer patients with concurrent and recurrent liver metastasis underwent preoperative radiotherapy, surgery and adjuvant chemotherapy with emphasis on the time of presence of hepatic spread. METHODOLOGY(More)
We analyzed a teaching institution's experience with intra-operative cholangiography (IOCG) and endoscopic retrograde cholangiopancreatography (ERCP) and established an algorithm for their timing and use. The records of all patients undergoing LC during a five year period were reviewed. Patients with a history of jaundice or pancreatitis, abnormal(More)
BACKGROUND/AIMS Gastrointestinal stromal tumors (GIST) are the most frequent non-epithelial tumors of the alimentary tract. The interstitial cells of Cajal or more primitive progenitor mesenchymal cells are suggested as their cells of origin. GIST's occur throughout the gastrointestinal tract but are generally located in the stomach and the intestine. About(More)
Dermatofibrosarcoma protuberans (DFSP) is a morphologically distinct dermal/subcutaneous fibrohystiocytic neoplasm seen mainly on the trunk and the proximal extremities, which generally is regarded as a low-grade or "borderline" neoplasm. Dermatofibrosarcoma protuberans is characterized clinically by locally aggressive growth and a high rate of local(More)
The etiological role of human papillomavirus (HPV) in a number of squamous malignant tumors is well known. Squamous cell carcinoma (SCC) of colon is a rare disease with uncertain etiology. Our objective was to detect possible HPV infection in a colon SCC patient. The 94-year-old female patient was operated due to colon tumor causing passage disturbances.(More)
Centrally located breast cancers account for 5-20% of all breast cancer cases. Historically, patients with central breast cancers were not offered breast conservation surgery but conventional mastectomy only. The relatively frequent nipple-areola-complex involvement and consequent nipple-areolar resections with an adequate safety margin around the tumor(More)
