This phase II clinical trial studies the side effects of giving dose dense doxorubicin-cyclophosphamide and paclitaxel regimen without pegfilgrastim in the paclitaxel portion in treating patients with stage I-III breast cancer. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Granulocyte-colony stimulating factors, such as pegfilgrastim, are used to increase the numbers of white blood cells in patients who are receiving chemotherapy in order to prevent fevers and infections. Giving dose dense doxorubicin-cyclophosphamide and paclitaxel regimen without pegfilgrastim in the paclitaxel portion may be a better way to treat patients with stage I-III breast cancer.

PRIMARY OBJECTIVE:
I. To evaluate the rate of paclitaxel treatment completion omitting Neulasta (pegfilgrastim) using pre-specified safety rules within 7 weeks (from day 1 [D1] of cycle 1 of paclitaxel to D1 of cycle 4 of paclitaxel).
SECONDARY OBJECTIVES:
I. To characterize the utilization of Neulasta (pegfilgrastim) using pre-specified safety rules in patients receiving dose dense paclitaxel.
II. To evaluate safety of omitting Neulasta (pegfilgrastim) support using pre-specified safety rules in patients receiving dose dense paclitaxel (according to the Cancer Therapy Evaluation Program [CTEP] active version of the National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE], version 4).
IIa. To estimate the rate of hematological toxicity, including the incidence of grade 3-5 neutropenia and febrile neutropenia among the 4 cycles of paclitaxel;
IIb. To estimate the rate of other toxicities grade 3-4 among the 4 cycles of paclitaxel.
III. To evaluate the schedule impact of omitting Neulasta (pegfilgrastim) support using pre-specified safety rules in patients receiving dose dense paclitaxel.
IIIa. To estimate the percentage of patients who receive all planned cycles of chemotherapy;
IIIb. To characterize reasons for treatment delays (defined as schedule/preference, absolute neutrophil count [ANC] < 1,000/mm^3, hypersensitivity, neurotoxicity, transaminitis, other).
IV. To estimate the safety of simplifying the pre-medication regimen used for the paclitaxel portion of the regimen (withholding premedication after 2 cycles without evidence of allergic reactions).
IVa. To evaluate the rate of hypersensitivity reactions on cycles 3-4 of paclitaxel, when steroid is avoided.
EXPLORATORY OBJECTIVE:
I. To estimate the impact on costs of omitting Neulasta (pegfilgrastim) support using pre-specified safety rules in patients receiving dose-dense paclitaxel.
Ia. To calculate the costs of omitting Neulasta (pegfilgrastim) using the planned treatment algorithm.
OUTLINE:
Patients receive paclitaxel intravenously (IV) over 3 hours on day 1 of each cycle. Treatment repeats every 2 weeks for up to 4 cycles in the absence of disease progression or unacceptable toxicity. If during the course of treatment with paclitaxel patients experience an episode of fever and neutropenia or have an active infection, patients receive pegfilgrastim subcutaneously (SC) on day 2 for all future cycles.
After completion of study treatment, patients are followed up for 4 weeks.
