Adjuvant Stage 2-3A Breast Cancer With Positive Lymph Nodes

Breast Cancer Clinical Trial

Official title: A Phase II Study Of Safety And Tolerability Of Adjuvant Chemotherapy With Continuous Infusion Paclitaxel And Dose Intense Cyclophosphamide And Hematopoietic Growth Factor Support Followed By Doxorubicin For Stage II-IIIA Breast Cancer Involving Greater Than or Equal to 10 Lymph Nodes

Status Completed

Clinical Trial 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. Radiation therapy uses high-energy x-rays to damage tumor cells.

PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with filgrastim and radiation therapy works in treating patients with stage II or stage IIIA breast cancer.

Clinical Trial Description

OBJECTIVES:

• Determine the feasibility of administering adjuvant paclitaxel, dose-intensive cyclophosphamide, and filgrastim (G-CSF), followed by doxorubicin and then radiotherapy in patients with stage II or IIIA breast cancer involving > 4 lymph nodes.

• Determine the incidence of febrile neutropenia in these patients during the first course of therapy.

• Compare the incidence of febrile neutropenia and duration of neutropenia in patients treated with this regimen with that seen in patients treated on protocol CWRU-4194.

• Determine the disease-free and overall survival of patients treated with this regimen.

• Evaluate the quality of life of these patients.

• Correlate HER-2/neu overexpression with disease-free and overall survival in these patients.

OUTLINE: Patients receive paclitaxel IV continuously and cyclophosphamide IV over 2 hours on days 1-3. Patients also receive filgrastim (G-CSF) subcutaneously (SC) beginning on day 5 and continuing until day 14 or until blood counts recover. Treatment repeats every 21 days for 3 courses. Patients then receive doxorubicin IV on day 1 and G-CSF SC on days 2-11 every 21 days for 4 courses.

Patients with hormone receptor positive disease also receive oral tamoxifen daily for 5 years beginning at the completion of chemotherapy.

Beginning 3-6 weeks after the completion of chemotherapy, patients receive radiotherapy 5 days a week for 6-7 weeks.

Quality of life is assessed days 1 and 4 of the first course of chemotherapy, day 1 of the second course, the last day of the final course, and at 6 months after the completion of treatment.

Patients are followed every 3 months for 2 years and then every 6 months thereafter.

PROJECTED ACCRUAL: A total of 26 patients will be accrued for this study. ;
