Brief summary: This prospective, open-Label, comparative, randomized, controlled phase III trial was designed to compare the clinical performance of gemcitabine with capecitabine vs. capecitabine alone for patients with biliary tract cancer (BTC) after curative resection.

Detailed description: Currently, complete surgical resection represents the only potentially curative treatment option for cholangiocarcinoma (CCA, including intrahepatic, hilar and distal CCA) and gallbladder carcinoma (GBCA). Because of high rates of disease recurrence and poor survival rates following surgical resection, postoperative treatment have been considered to improve patient survival after resection of BTC. The systematic review showed a beneficial impact of adjuvant treatment in BTC, particularly in patients with involved lymph nodes or resection margins and distal or hilar CCA. However, in regard of the paucity of randomized data, current guidelines recommend inclusion in clinical trials.

Previously, the data of the BILCAP trial showed an improvement in median overall survival for capecitabine compared to observation alone for BTC, indicating capecitabine as the new standard postoperative treatment after curative resection of BTC.

Previous phase II studies for advanced BTC showed superiority of the combination gemcitabine/ capecitabine regimen vs. the capecitabine monotherapy, the median OS was 12.7-14 vs. 7.9 months.

Based on these data, this AdBTC trial will was designed to compare the clinical performance of gemcitabine with capecitabine vs. capecitabine alone for patients with biliary tract cancer (BTC) after curative resection, aiming for superiority of the combination regimen vs. the oral monotherapy. This will be based on the BILCAP protocol, applying the similar dosing, assessments and dose modifications.

The primary endpoint is DFS and secondary endpoints include recurrence free survival, OS, safety and tolerability of adjuvant CTx, quality of life, and patterns of disease recurrence.

Eligibility criteria: DISEASE CHARACTERISTICS:

* Histologically confirmed biliary tract cancer (including intrahepatic, extrahepatic, hilar cholangiocarcinoma or muscle invasive gallbladder cancer or cancer of the distal bile duct)
* Must have undergone a radical surgical approach which includes liver resection, pancreatic resection, or less commonly both
* Patients with pathological evidence of microscopic involvement of the margins of the excised specimen are eligible as long as resection is macroscopically complete
* Must be able to start treatment within 12 weeks of surgery
* No pancreatic or periampullary cancer
* No mucosal gallbladder cancer

PATIENT CHARACTERISTICS:

* Adequate surgical biliary drainage with no evidence of infection
* Not pregnant or nursing
* Negative pregnancy test for women of childbearing age and childbearing potential
* Fertile patients must use effective contraception during study treatment and for at least 3 months after study treatment has ended
* Must provide written informed consent
* No history of other malignant diseases within the past 5 years
* No serious coexisting medical condition likely to interfere with protocol treatment, including a potential serious infection
* No evidence of significant clinical disorder or laboratory finding that makes it undesirable for the patient to participate in the trial
* No psychological, familial, sociological, or geographical factors considered likely to preclude study compliance
* No other serious uncontrolled medical conditions
* No unresolved biliary tree obstruction
