About this study
Official title: Phase III Trial of Continuous Schedule AC + G vs. Q 2 Week Schedule AC, Followed by Paclitaxel Given Either Every 2 Weeks or Weekly for 12 Weeks as Post-Operative Adjuvant Therapy in Node-Positive or High-Risk Node-Negative Breast Cancer
RATIONALE: Drugs used in chemotherapy, such as doxorubicin, cyclophosphamide, and paclitaxel, use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving them after surgery may kill any remaining tumor cells. It is not yet known which combination chemotherapy regimen is more effective in treating resected breast cancer.
PURPOSE: This randomized phase III trial is comparing 2 different regimens of combination chemotherapy to see how well they work in treating patients who have undergone surgery for stage I, stage II, or stage III breast cancer.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
RATIONALE: Drugs used in chemotherapy, such as doxorubicin, cyclophosphamide, and paclitaxel, use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving them after surgery may kill any remaining tumor cells. It is not yet known which combination chemotherapy regimen is more effective in treating resected breast cancer.
PURPOSE: This randomized phase III trial is comparing 2 different regimens of combination chemotherapy to see how well they work in treating patients who have undergone surgery for stage I, stage II, or stage III breast cancer.
Detailed description
OBJECTIVES:
- Compare the disease-free survival of patients with node-positive or high-risk node-negative breast cancer treated with 2 different schedules of adjuvant doxorubicin, cyclophosphamide, and paclitaxel.

- Correlate outcome with putative prognostic markers in patients treated with these regimens.

Beginning 2 weeks after completion of doxorubicin and cyclophosphamide, patients receive paclitaxel IV over 1 hour on day 1. Treatment repeats every 7 days for 12 courses.
In all arms, treatment continues in the absence of disease progression or unacceptable toxicity.
In all arms patients with HER2/neu-positive tumors also receive trastuzumab (Herceptin®) weekly or every 3 weeks beginning concurrently with paclitaxel OR 3 months after the last dose of paclitaxel and continuing for up to 52 weeks.
In all arms, patients with estrogen-receptor or progesterone-receptor positive tumors receive hormonal therapy beginning within 28 days of the completion of adjuvant chemotherapy or radiotherapy (if given).

Where is the study taking place?
The record lists 542 sites in United States, Canada, Puerto Rico. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 17 Apr 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Disease-free Survival (time frame: every 6 months (annually for mammograms) for 5 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00070564, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Aug 2026.
