Study of S-1 Oxaliplatin (SOX) for Biliary Tract Cancer (BTC) (Ampullary Adenocarcinoma)

Study Overview
=================
Brief Summary
-----------------
To evaluate efficacy and safety of S-1 Oxaliplatin (SOX) regimen to patients with unresectable, metastatic or locally advanced biliary tract or ampullary adenocarcinoma.

Detailed Description
-----------------
To list in cases with unresectable, metastatic or locally advanced biliary tract or ampullary adenocarcinoma that have not been treated before,confirm the efficacy and safety of combined S-1/L-OHP regimen for the biliary tract or ampullary carcinoma, providing evidence-based proof for the future treatment.
