Brief Summary:
The investigators are going to explore the diagnostic and prognostic value of circulating tumor cells and exosomes extracted from the portal venous blood obtained with endoscopic ultrasound in pancreatic cancer patients.

Condition or disease Intervention/treatment
Pancreatic Cancer Procedure: Endoscopic ultrasound-guided protal venous blood sampling

Detailed Description:
As the prognosis of pancreatic cancer, a kind of malignant tumor, remains poor due to the low diagnostic rate at the early stage, there is still a significant clinical need to determine individualized tumor molecular profiles and personalized risk for recurrence. Circulating tumor cells (CTCs) and exosomes from patients with primary tumors may hold promise in serving as an informative biomarker to address this clinical need. Here in this study, the investigators are going to explore the feasibility and safety of sampling portal venous blood via endoscopic ultrasound (EUS), and detect portal venous CTCs and analyze mRNA markers of exosomes by RNA-seq. The investigators aim to explore the potential molecular mechanisms in tumor microenvironment and mechanisms of drug resistance.

Study Type : Observational
Estimated Enrollment : 30 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Acquisition of Portal Venous Circulating Tumor Cells and Exosomes From Patients With Pancreatic Cancer by Endoscopic Ultrasound: a Prospective Study
Actual Study Start Date : August 1, 2018
Estimated Primary Completion Date : August 2020
Estimated Study Completion Date : September 2020


Group/Cohort Intervention/treatment
Pancreatic cancer
Endoscopic ultrasound-guided protal venous blood sampling will be performed for each patient. And the diagnosis will be confirmed by tissue pathology.
Procedure: Endoscopic ultrasound-guided protal venous blood sampling
We wil obtain portal venous blood samples via endoscopic ultrasound(EUS) in patients with suspected pancreatic masses.

Benign pancreatic diseases
Endoscopic ultrasound-guided protal venous blood sampling will be performed for each patient. And the diagnosis will be confirmed by tissue pathology, e.g. PCLs.
Procedure: Endoscopic ultrasound-guided protal venous blood sampling
We wil obtain portal venous blood samples via endoscopic ultrasound(EUS) in patients with suspected pancreatic masses.




Primary Outcome Measures :
  1. The difference of the amount of circulating tumor cells acquisited from portal venous blood between patients with pancreatic cancer and benign pancreatic diseases [ Time Frame: 08/01/2018-08/01/2020 ]
    In this study, the amount of the circulating tumor cells obtained from portal venous blood of suspected pancreatic masses patients will be determined by analyzing the expression of folate receptors. The investigators will compare the difference of the CTC amount between patients with pancreatic cancer and benign pancreatic diseases.

  2. The difference of the exosomes acquisited from portal venous blood between patients with pancreatic cancer and benign pancreatic diseases [ Time Frame: 08/01/2018-08/01/2020 ]
    Exosomes will be acquisited from portal venous blood of patients with suspected pancreatic masses. Then the total RNA will be extracted from the exosomes. The investigators will compare the expression of certain mRNA markers of the exosomes between patients with pancreatic cancer and benign pancreatic diseases. (The mRNA markers will be selected from RNA-seq results.)


Secondary Outcome Measures :
  1. The difference of the amount of circulating tumor cells between portal venous and peripheral blood [ Time Frame: 08/01/2018-08/01/2020 ]
    In this study, the amount of the circulating tumor cells obtained from portal venous blood and peripheral blood will be assessed for each patient respectively. The investigators will compare the difference of the CTC amount between portal venous blood and peripheral blood.

  2. The difference of the exosomes between portal venous and peripheral blood [ Time Frame: 08/01/2018-08/01/2020 ]
    Exosomes will be acquisited from portal venous blood and peripheral blood for each patient. Then the total RNA will be extracted from the exosomes. The investigators will compare the expression of certain mRNA markers of the exosomes between portal venous and peripheral blood for each patient. (The mRNA markers will be selected from RNA-seq results.)


Biospecimen Retention:   Samples With DNA
We will obtain portal venous blood samples via endoscopic ultrasound(EUS) in patients with suspected pancreatic masses, detect circulating tumor cells and analyze the mRNA markers of the exosomes by RNA-seq.
