Combination Chemotherapy Plus Warfarin in Treating Patients With Prostate Cancer

Status:
Completed
Trial end date:
1969-12-31
Target enrollment:
0
Participant gender:
Male
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 may kill more tumor cells. Anticoagulant drugs such as warfarin may reduce the risk of blood clots. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus warfarin in treating patients who have prostate cancer.
Phase:
Phase 2
