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).

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.
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.

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.

Dipeptidyl peptidase-IV (DPP-IV) and fibroblast activation protein alpha (FAP) are aminopeptidases that regulate several bioactive peptides involved in glucoregulation, and are frequently dysregulated in cancer. The present study analyzes blood plasma levels and the quantity and localization of DPP-IV and FAP in PDAC tissues.

Methods: Expressions of miRNA-192, -196, -200, -21, -30 and -423 were measured in 77 patients with PAC and 64 non-cancer patients (34 patients with type 2 DM and 30 control persons). 60 patients with PAC (78%) had DM or prediabetes and it was of new-onset (less than 2 years before the cancer diagnosis) in 44 out of them.
Diabetes mellitus and pancreatic cancer establish both-side relationship, one disease may have influence a development of the other. Pathogenic mechanisms sharing their relationship are overviewed. Early diagnosis may contribute to better prognosis of the patients with malign tumor.

Risk factors (long-term diabetes, obesity) and early symptoms (new-onset diabetes, loss of weight, or persistent low body mass) are the initial symptoms of pancreatic carcinogenesis. They may be influenced by antidiabetic drugs and their correct evaluation is a prerequisite for early diagnosis of pancreatic cancer (PC). We review the risk factors, early symptoms, and the impact of antidiabetic drugs on early pancreatic carcinogenesis.

Promising method, which helps to distinguish between chronic pancreatitis and cancer, is point mutations of the proto-oncogene KRAS test. This method is not established in routine clinical practice yet.

Its prevalence continuously increases, mortality does not decrease, diagnosis is frequently late, radical surgery is limited to 15-20 % of patients, postoperative relapses are frequent, and chemotherapy has a palliative character. Preventive programs are the only possibility of improvement.

Local symptoms are present at a late stage of the disease and in the majority of cases do not enable radical surgery. Intervention is possible only in locally restricted tumor and remains the only chance of significant survival.

Colorectal cancer (CRC) is the second most common cancer in Europe and its incidence is steadily increasing. This trend could be reversed through timely secondary prevention (screening). In the last twenty years, CRC screening programs across Europe have experienced considerable improvements (fecal occult blood testing; transition from opportunistic to population based program settings).

Its differentiation from the common type 2 diabetes is the prerequisite for early diagnosis of pancreatic adenocarcinoma. Little attention has been paid to pancreatic stroma and surface proteases.

Contamination with prolamins of other cereals is frequent, and some clinical and experimental studies support the view that a subgroup of celiac patients may be intolerant to pure oats. Thus, this issue is more complex than previously suggested.

Every year, 412 000 people are diagnosed with this condition, and 207 000 patients die of it. In 2003, recommendations for screening programs were issued by the Council of the European Union (EU), and these currently serve as the basis for the preparation of European guidelines for CRC screening.

Methods: Thirty-nine patients with liver cirrhosis diagnosed by means of biopsy and clinical examinations were randomly allocated to treatment with E. coli Nissle or placebo for 42 days.
