Adjuvant Capecitabine vs Gemcitabine Plus Cisplatin in Resected Extrahepatic Cholangiocarcinoma

There is no proven adjuvant treatment after curative surgical resection in patients with cholangiocarcinoma, although previous meta-analysis suggested potential survival benefit of adjuvant chemotherapy or radiotherapy in patients with lymph node-positive resected cholangiocarcinoma. Despite of lack of level 1 evidence and no data which regimen is optimal, adjuvant chemotherapy is widely used in daily practice setting. Based on this background, the investigators designed the randomized phase 2 trial comparing capecitabine and gemcitabine plus cisplatin in patients with resected lymph node-positive extrahepatic cholangiocarcinoma.
