Condition(s) targeted: Breast Cancer
Intervention: filgrastim (Biological); carboplatin (Drug); cyclophosphamide (Drug); doxorubicin hydrochloride (Drug); paclitaxel (Drug); thiotepa (Drug); peripheral blood stem cell transplantation (Procedure)
Phase: Phase 2

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: This randomized phase II trial is studying two different regimens of combination
chemotherapy and comparing them to see how well they work in treating patients with
high-risk primary stage II or stage III breast cancer.
Official title: Randomized Phase II Study of Adriamycin/Cytoxan/Taxol (ACT) vs. Cytoxan, Thiotepa, Carboplatin (STAMP V) in Patients With High-Risk Primary Breast Cancer
Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
Primary outcome: Five-Year Relapse-free Survival
Secondary outcome: Five-Year Overall Survival
- Compare the toxic effects of doxorubicin, cyclophosphamide, and paclitaxel vs
cyclophosphamide, thiotepa, and carboplatin in patients with high-risk primary breast
cancer. (Arm I closed to accural as of 4/6/2006.)
- Compare the efficacies of these regimens followed by peripheral blood stem cell rescue
in these patients.
- Determine the efficacy of a bisphosphonate to prevent relapse/metastasis after
high-dose chemotherapy in these patients.
OUTLINE: This is a randomized study. Patients are stratified by stage of disease.
Peripheral blood stem cells (PBSC) are collected after mobilization with filgrastim (G-CSF),
administered subcutaneously or IV, twice daily beginning 3 days before collection and
continuing until collection is complete.
All patients receive conventional-dose adjuvant chemotherapy, probably comprising
doxorubicin IV, cyclophosphamide IV, and fluorouracil IV over 1 hour on days 1, 22, 43, and
64. Patients are then randomized to receive 1 of 2 treatment arms of high-dose chemotherapy.
(Arm I closed to accrual as of 4/6/2006.)
- Arm I (ACT) (closed to accrual as of 4/6/2006): Patients receive doxorubicin IV over 24
hours on days - 9 to -6, cyclophosphamide IV over 2 hours on day -5, and paclitaxel IV
over 24 hours on day - 2. PBSC are reinfused on days -2 and 0. G-CSF is administered
beginning on day 0 and continuing until blood counts recover.
- Arm II (STAMP V): Patients receive cyclophosphamide IV, carboplatin IV, and thiotepa IV
over 24 hours on days - 7 to -4. PBSC are reinfused and G-CSF is administered as in arm
Within 4-6 weeks of day 0 of high-dose chemotherapy, patients with estrogen and/or
progesterone receptor positive tumors receive oral tamoxifen twice daily for 5 years.
Patients are also randomized to receive a bisphosphonate comprising pamidronate IV every 4
weeks for 2 years.
Quality of life is assessed before therapy, at 30 days after high-dose chemotherapy, and at
6 and 12 months.
Patients are followed every 3 months for 1 year and then every 6 months for at least 10
