HYPOTHESIS Accurate differentiation between inflammatory and neoplastic tumors of the pancreas remains a diagnostic dilemma for surgeons. The aim of the study was to assess the utility of 2 neoplastic markers, cancer antigen (CA) 19-9 and CA 125, in the differential diagnosis of pancreatic tumors. DESIGN The patients were assigned to a malignant or benign(More)
OBJECTIVE The aim of this study was to evaluate the efficacy of adjuvant chemotherapy with etoposide, Adriamycin and cisplatin (EAP) after potentially curative resections for gastric cancer. METHODS After surgery, patients were randomly assigned to the EAP or control arm. Chemotherapy included 3 courses, administered every 28 days. Each cycle consisted of(More)
Circulating anti-p53 protein antibodies (p53-Abs) have been detected in some cancer patients. The aim of the study was to determine the presence of circulating anti-p53 protein antibodies and their clinical significance in patients with esophageal carcinoma. Serum specimens from 75 consecutive patients with squamous cell carcinomas and 10 healthy subjects(More)
The following, from the 12th OESO World Conference: Cancers of the Esophagus, includes commentaries on the role of salivary stimulation and esophageal secretion of protective factors in prevention of adenocarcinoma sequelae in gastroesophageal reflux disease; the pediatric conditions associated with esophageal cancer; the relationship of achalasia and(More)
THE AIM OF THE STUDY was to assess angiogenesis markers - endostatin and endothelial growth factor (EGF) as markers of detection of gastric carcinoma. MATERIAL AND METHODS. The study involved 20 patients with colorectal cancer (10 women, 10 men) aged 35 - 75 years, mean age = 55 years ± 11.2 who referred to the 2nd Department of General Surgery, Medical(More)
UNLABELLED Two molecules - vascular endothelial growth factor involved in new vessels formation and survivin - antiapoptotic protein, reported to be associated with worse prognosis in various malignancies have been chosen for the study. Both are potential target for novel therapies. THE AIM OF THE STUDY Was to determine the immunostaining of VEGF and(More)
Little is known about how the immune system impacts human colorectal cancer invasiveness and stemness. Here we detected interleukin-22 (IL-22) in patient colorectal cancer tissues that was produced predominantly by CD4(+) T cells. In a mouse model, migration of these cells into the colon cancer microenvironment required the chemokine receptor CCR6 and its(More)
Inflammatory fibroid polyp is one of the chronic inflammatory diseases in the digestive tract, which often mimics the submucosal tumor. Precise diagnosis is possible after removal of the detected lesion. Endoscopic removal is recommended as a safe and efficient method of the treatment. In this report the authors present a case of inflammatory fibroid polyp(More)
Survivin is a member of the family of proteins, which inhibit apoptosis (inhibitor of apoptosis proteins - IAP). Expression of survivin was found in colorectal cancer, neuroblastoma, bladder cancer, non-small cell lung cancer, and breast cancer. There is some recent data indicating the correlation of poor prognosis and worse response to chemotherapy in(More)
