Study Description

Brief Summary

Purpose of this study is to understand the clinical feasibility of duodenal juice diagnosis to screen UICC stage II pancreatic ductal adenocarcinoma patients.

Detailed Description

Pancreatic cancer (PC) is the most lethal of all major cancers with a five year survival rate of 5 %. While stage I and II tumors leads to an improvement in survival, almost all PCs are currently diagnosed at more advanced non-resectable stages since minimally invasive technique which is capable of screening early-stage PC does not exist. Serum CA19-9 is not recommended as a screening technique because of its low sensitivity and specificity. Imaging modalities such as MRI, CT, EUS and ERCP are more accurate but are not appropriate screening tools due to their high cost, discomfort and complications. Therefore, there is a strong demand for a screening tool with high sensitivity and specificity which is highly acceptable for the patient.

The investigators would like to standardize the detection method of pancreatic cancer that uses the duodenal juice as an optional endoscopic diagnosis. It's a very useful chance to collect pancreatic juice from duodenum, it is called "duodenal juice" ,if we collect them without additional invasion. The investigators would like to collect duodenal juice during undergoing upper gastrointestinal endoscopy and analyze the pancreatic tumor markers in duodenal juice. A definite diagnosis of the patient is made with histology, cytology or imaging diagnosis and the result of each definite diagnosis is correlated to the each marker analyzing result of duodenal juice. Therefore this study can be positioned as a feasibility study to confirm clinical performance.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Test subject

Other: Tumor markers
Duodenal juice are collected using endoscope and cannula. Tumor markers of collected samples are analyzed. The marker concentration is applied to statistical analysis.

Outcome Measures

Primary Outcome Measures

  1. The Concentration of the Pancreatic Cancer Markers of the Normal Cohort and UICC Stage II Pancreatic Ductal Adenocarcinoma Cohort [1year]

    We hypothesized that there is a statistically-significant difference between two cohorts. The cancer marker is S100P.

Secondary Outcome Measures

  1. The Sensitivity and Specificity to Detect UICC Stage II Pancreatic Ductal Adenocarcinoma Among All Participants. [1 year]

    Based on each analyzing result of pancreatic cancer markers and corresponding final diagnosis, a receiver operating characteristic (ROC) is evaluated. A cut-off is then chosen from this ROC curve to maximize both sensitivity and specificity.<Method>1. create an ROC curve using the measured concentrations, 2. set a threshold, 3. report how many patients in each group would are exceeded the threshold. (The rate of exceeded threshold in Test subject group is sensitivity, The rate of 1-(the rate of exceeded threshold in Control group) is specificity.)
