RATIONALE: Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop tumor cells from dividing so they stop growing or die. Anticoagulants such as dalteparin may help prevent blood clots in patients being treated with gemcitabine for unresectable or metastatic pancreatic cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of gemcitabine with or without dalteparin in treating patients who have unresectable or metastatic pancreatic cancer.

Condition	Treatment or Intervention	Phase
adenocarcinoma of the pancreas Pancreatic Cancer Quality of Life Thromboembolism	Drug: dalteparin  Drug: gemcitabine  Procedure: anti-cytokine therapy  Procedure: antiangiogenesis therapy  Procedure: anticoagulation  Procedure: biological response modifier therapy  Procedure: chemotherapy  Procedure: growth factor antagonist therapy  Procedure: quality-of-life assessment  Procedure: supportive care/therapy	Phase III

OBJECTIVES:

• Compare the quality of life of patients with unresectable or metastatic pancreatic cancer treated with gemcitabine with or without dalteparin.
• Compare the survival of patients treated with these regimens.
• Compare the incidence of venous thromboembolic complications in patients treated with these regimens.
• Determine the safety of dalteparin, in terms of bleeding complications, in these patients.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to disease stage (unresectable nonmetastatic vs metastatic). Patients are randomized to one of two treatment arms.

• Arm I: Patients receive gemcitabine IV over 30 minutes once weekly on weeks 1-7 for the first course only. Beginning on week 9, patients receive gemcitabine IV over 30 minutes once weekly for 3 weeks. Treatment then repeats every 4 weeks for up to 6 months in the absence of unacceptable toxicity or disease progression.
• Arm II: Patients receive gemcitabine as in arm I and dalteparin subcutaneously once daily for 6 months in the absence of unacceptable toxicity. Quality of life is assessed at baseline and every 4 weeks during study therapy.

Patients are followed every 4 weeks.

PROJECTED ACCRUAL: A total of 400 patients (200 per treatment arm) will be accrued for this study within 40 months.
