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.
- 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.
Treatment continues in the absence of disease progression or unacceptable toxicity.
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.

Safety and efficacy of alternating treatment with EP2006, a filgrastim biosimilar, and reference filgrastim: a phase 3, randomised, double-blind clinical study in the prevention of severe neutropenia in patients with breast cancer receiving myelosuppressive chemotherapy.
In 2015, the biosimilar filgrastim EP2006 became the first biosimilar approved by the US Food and Drug Administration (FDA) for commercial use in the United States, marketed as Zarxio®. This phase 3 ...

One of the SELECTIVE ESTROGEN RECEPTOR MODULATORS with tissue-specific activities. Tamoxifen acts as an anti-estrogen (inhibiting agent) in the mammary tissue, but as an estrogen (stimulating agent) in cholesterol metabolism, bone density, and cell proliferation in the ENDOMETRIUM.
Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.
An enzyme that, in the presence of ATP and COENZYME A, catalyzes the cleavage of citrate to yield acetyl CoA, oxaloacetate, ADP, and ORTHOPHOSPHATE. This reaction represents an important step in fatty acid biosynthesis. This enzyme was formerly listed as EC 184.108.40.206.
Radiotherapy given to augment some other form of treatment such as surgery or chemotherapy. Adjuvant radiotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
