Filgrastim Plus Chemotherapy Compared With Filgrastim Alone In Treating Women Undergoing Peripheral Stem Cell Transplantation For Breast Cancer

• Status: Completed
• Trial end date: 2006-03-09
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system recover from the side effects of chemotherapy. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. It is not yet known which treatment regimen is more effective for breast cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy plus filgrastim with filgrastim alone in treating women undergoing peripheral stem cell transplantation for stage II, stage III, or metastatic breast cancer.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No
