Development of a Prediction Platform for Neoadjuvant Treatment and Prognosis in Pancreatic Cancer Using Organoid

Study Overview
=================
Brief Summary
-----------------
The investigators create organoid from the pancreatic cancer tissue obtained via EUS-FNA and EUS-FNB within the pancreatic cancer diagnostic process. And also the investigators create organoid from the pancreatic cancer tissue obtained after surgery as part of the pancreatic cancer treatment process. Check for the reactivity to anti-cancer drugs through cell viability assay after treating with various anti-cancer drugs, such as anti-cancer drugs used as neoadjuvant chemotherapy for pancreatic cancer to the organoid. Also, perform genomic analysis on each organoid, and then check if there are any unique genomic mutations for each organoid. By recognizing the relationship between the unique genomic mutations and reactivity to the anti-cancer drug within pancreatic cancer patients eligible for surgery, the investigators aim to strategize appropriate neoadjuvant chemotherapy before surgery, thus developing a platform to predict the outcomes of each patient.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall survival rate | The percentage of people in a group who are still alive for a certain period of time after they were started adjuvant chemotherapy for pancreatic cancer | From date of initiation of adjuvant chemotherapy after surgery until the date of death from any cause, assessed up to 36 months |
