Phase I/II Study of Paclitaxel Added to High-Dose Carboplatin/Cyclophosphamide with Autologous Peripheral Blood Stem Cell Support for Women with High-Risk Stage II/III Breast Cancer (Summary Last Modified 07/2000)
Alternate Title Addition of Paclitaxel to High-Dose Combination Chemotherapy in Treating Patients With High-Risk Breast Cancer
Objectives I. Estimate the maximum tolerated dose of paclitaxel when given with high-dose carboplatin/cyclophosphamide with autologous peripheral blood stem cell support in women with high-risk stage II/III breast cancer. II. Assess the nonhematologic toxicities associated with this combination. III. Assess the progression-free and overall survival of these patients following this treatment. Entry Criteria Disease Characteristics: Histologically diagnosed adenocarcinoma of the breast of the following stages: Stage II/IIIA disease with 4 or more involved axillary lymph nodes Stage IIIB Inflammatory No bone marrow involvement documented on bone marrow aspiration and biopsy Prior breast cancer allowed Hormone receptor status: Not specified Prior/Concurrent Therapy: At least 3 courses of induction therapy required, with regimen at the discretion of the investigator No disease progression during induction Patient Characteristics: Age: 18 to 65 Sex: Women only Menopausal status: Not specified Performance status: Karnofsky 70%-100% Hematopoietic: Not specified Hepatic: Bilirubin no greater than 2.0 mg/dL Renal: Creatinine clearance at least 60 mL/min Cardiovascular: Left ventricular ejection fraction at least 50% by MUGA No abnormal cardiac conduction documented as second- or third-degree heart block or bundle branch block Pulmonary: DLCO at least 60% of predicted Other: Not HIV positive No history of second malignancy within 5 years except: Nonmelanomatous skin cancer In situ carcinoma of the cervix No pregnant women Projected Accrual It is expected that 24-30 patients will be accrued; a study duration of 1-1.5 years is anticipated. Outline This is a dose-finding study. All patients undergo collection of peripheral blood stem cells (PBSC) with granulocyte colony-stimulating factor (G-CSF) mobilization prior to high-dose chemotherapy. Cohorts of 3-5 patients are treated at successively higher dose levels of paclitaxel until a maximum tolerated dose (MTD) is found. Paclitaxel is given as a single 6-hour infusion, followed by fixed doses of high-dose cyclophosphamide for 2 days, then carboplatin for 3 days. Four days later, patients receive PBSC and G-CSF for hematopoietic reconstitution. Additional patients are entered at the MTD. Patients are followed every 3 months for 1 year, every 4 months for 1 year, then every 4-6 months thereafter. Disclaimer The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. Trial Lead Organizations St. Louis University Hospital Cancer Center
