Brief Summary

The present study is aimed at detecting and measuring mRNA levels of genes involved in epithelial to mesenchymal transition (EMT) in biological samples, i.e. in peripheral blood samples of pancreatic cancer (PC) patients and healthy controls, to determine the presence of disease, its progression and risk of recurrence.

Detailed Description

The investigators first provided evidence that human pancreatic cancer (PC) cells can undergo EMT during local invasion, and that EMT transcription factors (i.e.Twist family basic helix-loop-helix transcription factor 1 (TWIST1)) are increased in the blood of PC patients. In addressing the relevance of EMT in the metastatic process, the prognostic role of M-like cancer cells entering into the circulation remains to be determined.

Currently, the notion that cancer disseminates via the circulation led to increased attention on the identification of circulating tumor cells (CTCs) in blood samples ("liquid biopsy"; LB), so far exclusively based upon epithelial (E) markers. However, an un-biased evaluation of CTCs, providing meaningful information for cancer diagnosis up to therapy, cannot exclude cells with M features. LB data show that circulating TWIST1, zinc finger E-box binding homeobox 2 (ZEB2) and E-Cadherin (CDH1) messenger ribonucleic acids (mRNA) are significantly and steadily increased in the blood of PC patients.These findings indicate that high levels of EMT players in the circulation efficiently discriminate PC patients, irrespectively of tumor resectability.

The present study is aimed at detecting and measuring mRNA levels of genes involved in epithelial to mesenchymal transition in biological samples, i.e. in peripheral blood samples of tumor patients, to determine the presence of disease, its progression and risk of recurrence.

Aim of the study is to depict the molecular profile of EMT-Transcription factor (EMT-TFs) variations in the blood of patients with early, intermediate or advanced PC, with respect to disease progression and delivered treatments.

Primary endpoint: to determ the stage, the remission or the progression of a pancreatic cancer in a pancreatic cancer affected subjects. This end-point comprising the step of assaying a biological sample from said subject for the presence of a panel of mRNAs encoding for transcription factors involved in epithelial to mesenchymal transition.

Secondary endpoint: to identify biomarkers suitable for the selection of patients amenable of responsiveness to medical and surgical treatment.
