Combination Chemotherapy and Peripheral Stem Cell Transplantation in Treating Patients With Stage II or Stage IIIA Breast Cancer

• Status: Completed
• Trial end date: 2003-03-01
• 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. Combining chemotherapy with 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 regimen of combination chemotherapy is more effective for breast cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of two regimens of combination chemotherapy followed by peripheral stem cell transplantation in treating patients who have stage II or stage IIIA breast cancer.

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

Details

• Lead Sponsor: Fred Hutchinson Cancer Research Center
• Collaborator: National Cancer Institute (NCI)
• Treatments: Busulfan; Carboplatin; Cyclophosphamide; Melphalan; Paclitaxel; Sargramostim; Tamoxifen; Thiotepa
