RATIONALE: Drugs used in chemotherapy, such as gemcitabine and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. It is not yet known whether gemcitabine is more effective with or without cisplatin in treating cholangiocarcinoma or biliary tract tumors.

PURPOSE: This randomized phase III trial is studying gemcitabine and cisplatin to see how well they work compared to gemcitabine alone in treating patients with unresectable locally advanced or metastatic cholangiocarcinoma or other biliary tract tumors.

OBJECTIVES:

Primary

• Compare the overall survival of patients with unresectable locally advanced or metastatic cholangiocarcinoma or other biliary tract tumors treated with gemcitabine hydrochloride with vs without cisplatin.

Secondary

• Compare the progression-free survival of patients treated with these regimens.
• Compare the toxic effects of these regimens in these patients.
• Compare quality of life of patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to participating center, primary site of disease (gallbladder vs bile ducts vs ampulla), prior therapy (photodynamic therapy [PDT] vs non-PDT therapy vs none), ECOG performance status (0 vs 1 vs 2), and disease status (locally advanced vs metastatic). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1, 8, and 15. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.
• Arm II: Patients receive gemcitabine hydrochloride IV over 30 minutes and cisplatin IV over 1½ hours on days 1 and 8. Treatment repeats every 21 days for 8 courses in the absence of disease progression or unacceptable toxicity.

Quality of life is assessed at baseline, 12 weeks, and after finishing treatment.

After completion of study treatment, patients are followed periodically for at least 3 years.

PRIOR CONCURRENT THERAPY:

Chemotherapy

• At least 6 months since prior adjuvant chemotherapy
• No prior gemcitabine hydrochloride
• No prior cisplatin
• No prior systemic chemotherapy for locally advanced or metastatic disease except low-dose radiosensitizing chemotherapy in conjunction with radiotherapy

Radiotherapy

• Prior radiotherapy for localized disease allowed provided there is clear evidence of disease progression afterwards

Surgery

• Prior curative surgery allowed provided there is evidence of nonresectable disease relapse requiring systemic chemotherapy

Other

• Recovered from all prior therapies

• Prior photodynamic therapy (PDT) allowed provided it was given for localized disease only (with no evidence of metastatic disease) and resulted in subsequent disease progression after completion of therapy OR to relieve biliary obstruction in the presence of metastatic disease

  • PDT must have been completed ≥ 4 weeks ago

• At least 4 weeks since prior investigational agents

• No other concurrent, curative anticancer therapy
