fluorouracil with or without cisplatin in treating patients with advanced or metastatic cancer of the pancreas

Conditions: Pancreatic Cancer

Summary: rationale: drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. combining more than one drug and giving drugs in different ways may kill more tumor cells. it is not yet known whether fluorouracil plus cisplatin are more effective than fluorouracil alone in treating patients with metastatic cancer of the pancreas. purpose: randomized phase iii trial to compare the effectiveness of fluorouracil with or without cisplatin in treating patients who have advanced or metastatic cancer of the pancreas.

objectives: * confirm the value of chronomodulated infusion with respect to survival in patients with locally advanced or metastatic pancreatic cancer. * test the value of adding cisplatin to fluorouracil in extending survival in these patients. outline: this is a multicenter, randomized study. the study design is a 2 x 2 factorial such that patients are allocated to one of 4 treatment groups involving the use or absence of chronomodulation and cisplatin (cddp). treatment in each of the 4 groups is repeated for 3 courses where each course is a 5-day course of treatment. patients in the first group receive a chronomodulated schedule based on delivery of fluorouracil (fu). patients in the second group receive a chronomodulated schedule of fu and cddp. patients in the third and fourth experimental groups receive flat schedules of fu alone or fu and cddp, respectively. dosages of fu are increased across the three courses whereas dosages of cddp remain constant. treatment is continued until disease progression, severe toxicity, or complete remission for more than 4 months occurs. projected accrual: 200 patients will be accrued.
