About

RATIONALE: Drugs used in chemotherapy, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving capecitabine after surgery may kill any tumor cells that remain after surgery. Sometimes, after surgery, the tumor may not need more treatment until it progresses. In this case, observation may be sufficient. It is not yet known whether capecitabine is more effective than observation in treating biliary tract cancer.

PURPOSE: This randomized phase III trial is studying capecitabine to see how well it works compared with observation in treating patients with biliary tract cancer.

Full description

OBJECTIVES:

Primary

• To determine whether adjuvant chemotherapy with capecitabine has any effect on 2-year survival compared to expectant treatment alone (observation) in patients who have undergone a macroscopically complete surgical resection of a biliary tract cancer.

Secondary

• To compare capecitabine versus observation in terms of 5-year survival, relapse-free survival, toxicity, quality of life, and health economics.

OUTLINE: This is a multicenter, prospective, randomized study. Patients are stratified according to surgical center, disease site (hilar/extrahepatic cholangiocarcinoma vs intrahepatic cholangiocarcinoma vs gallbladder vs intrapancreatic/common bile duct), type of resection (R0 vs R1), and ECOG performance status (0 vs 1 vs 2). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive oral capecitabine twice a day on days 1-14. Treatment repeats every 3 weeks for 8 courses in the absence of disease progression or unacceptable toxicity.
• Arm II: Patients undergo expectant treatment (observation). Quality of life is assessed at baseline, every 3 months for 1 year, and then every 6 months for 1 year.

All patients are followed for up to 5 years post-randomization.

Inclusion and exclusion criteria

DISEASE CHARACTERISTICS:

• Histologically confirmed biliary tract cancer (including intrahepatic or extrahepatic/hilar cholangiocarcinoma or muscle invasive gallbladder cancer or cancer of the distal bile duct)

• 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 other than adequately treated nonmelanoma skin cancer or in situ carcinoma of the uterine cervix
• No serious co-existing 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

PRIOR CONCURRENT THERAPY:
