Oxaliplatin With Or Without Floxuridine and Leucovorin in Treating Patients With Metastatic Cancer of the Peritoneum

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 may kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of oxaliplatin with or without floxuridine and leucovorin in treating patients who have metastatic cancer of the peritoneum.

OBJECTIVES:

• Determine the maximum tolerated dose of intraperitoneal oxaliplatin with or without intraperitoneal floxuridine and leucovorin calcium in patients with metastatic cancer confined to the peritoneal cavity.
• Determine dose limiting and nondose limiting toxicities and pharmacokinetics of these treatment regimens in this patient population.

OUTLINE: This is a dose escalation study of oxaliplatin.

Patients receive intraperitoneal (IP) oxaliplatin over 1 hour on day 1 every 2 weeks for 2 courses.

Beginning at course 3, patients receive oxaliplatin with floxuridine and leucovorin calcium IP on day 1 and floxuridine and leucovorin calcium IP alone on days 2 and 3. Treatment repeats every 2 weeks in the absence of disease progression or unacceptable toxicity. Patients with complete surgical resection of disease receive a total of 6 courses of combination chemotherapy.

Cohorts of 3-6 patients receive escalating doses of oxaliplatin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose limiting toxicity.

PROJECTED ACCRUAL: A total of 3-40 patients will be accrued for this study.
