Accuracy of EUS and CEH EUS for the diagnosis of pancreatic tumours.

Objectives: The main objective is to compare the accuracy of EUS and CEH EUS for the diagnosis of pancreatic cancer (PC). The secondary objective is to evaluate the accuracy of EUS FNA and to determine to what extent EUS and CEH EUS findings are affected by endosonographer subjectivity.

Methods: A prospective single-centre study was conducted in patients with pancreatic lesions detected on CT.

Early detection of sporadic pancreatic cancer: time for change.

Sporadic pancreatic cancer amounts to ∼90% of all pancreatic cancers. It is a gloomy depressive disease and the most recalcitrant malignancy, with a very low 5-year survival (3-6%). At present, diagnostic methods are commonly applied, as used half a century ago, after the appearance of local and systemic symptoms (abdominal and back pain, cholestasis, painless jaundice, fatigue, anorexia, weight loss, anemia, peripheral phlebitis, and cachexia).

Lower plasma levels of glucose-dependent insulinotropic peptide (GIP) and pancreatic polypeptide (PP) in patients with ductal adenocarcinoma of the pancreas and their relation to the presence of impaired glucoregulation and weight loss.

Background: The changes in gastrointestinal hormones associated with pancreatic ductal adenocarcinoma (PDAC) in patients with impaired glucoregulation have yet to be evaluated. The aim of this study was to determine plasma concentrations of selected gastrointestinal hormones in PDAC patients with and without diabetes and to compare them with levels found in Type 2 diabetic patients without cancer.

Methods: In this study we examined plasma concentrations of glucose-dependent insulinotropic peptide (GIP), glucagon-like peptide 1 (GLP-1), pancreatic polypeptide (PP), peptide YY (PYY) and neuropeptide Y (NPY), and cytokines leptin and adiponectin in 94 patients with histologically confirmed PDAC.

Precursors of pancreatic cancer.

Pancreatic cancer (PC) behaves very differently in comparison with other malignancies. Its incidence has been increasing continuously; mortality has not decreased, the diagnosis is frequently late, radical surgery is performed only in 15-20% of patients, and chemotherapy is only palliative. PC occurs in three different forms.

Early detection of pancreatic cancer: impact of high-resolution imaging methods and biomarkers.

High-resolution imaging methods (HRIMs) and biomarkers present the second step of pancreatic cancer (PC) diagnostics in at-risk individuals. These include patients with positive risk factors, early symptoms, nonresponders to the initial antidiabetic therapy, patients older than 50 years of age with new-onset unstable diabetes requiring insulin as well as patients with long-term insulin-non-dependent diabetes and recent (up to 6 months) failure of antidiabetic therapy. The procedures should be started without delay and the co-operation between the primary and tertiary medical centers is highly desirable.
