Tamoxifen With or Without Combination Chemotherapy in Treating Postmenopausal Women With Operable Invasive Breast Cancer
A Phase 3 study testing cyclophosphamide, fluorouracil and methotrexate in people with Breast Cancer, run by Scottish Cancer Therapy Network at 9 sites in United Kingdom.
Trial summary
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen. Combining combination chemotherapy with hormone therapy may kill more tumor cells. Read more about this study

About this study
Official title: PROTOCOL FOR THE SCOTTISH POSTMENOPAUSAL CHEMO-ENDOCRINE TRIAL
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen. Combining combination chemotherapy with hormone therapy may kill more tumor cells.
PURPOSE: Randomized phase III trial to compare the effectiveness of tamoxifen with or without combination chemotherapy in treating postmenopausal women with stage I or stage II breast cancer that can be surgically removed.
Read the detailed description
OBJECTIVES: I. Compare the potential benefits of adjuvant tamoxifen with or without cyclophosphamide, methotrexate, and fluorouracil (CMF) in postmenopausal women with stage I-IIIA, unilateral, invasive breast cancer.
OUTLINE: This is a randomized study, multicenter study. Patients are stratified according to nodal status (positive vs negative or unknown) and hospital region. Patients undergo surgical resection with or without local radiotherapy, as appropriate. Radiotherapy begins within 8 weeks of surgery for patients randomized to arm I and within 4 weeks after completion of chemotherapy for patients randomized to arm II. Patients are randomized to 1 of 2 treatment arms, preferably within 2 weeks after surgery. Arm I: Beginning within 4 weeks after surgery, patients receive oral tamoxifen daily. Treatment continues for 5 years. Arm II: Beginning within 4 weeks after surgery, patients receive tamoxifen as in arm I and cyclophosphamide IV, methotrexate IV, and fluorouracil IV on day 1 (CMF). Chemotherapy continues every 3 weeks for 6 courses. Patients are followed every 6 months for 5 years and then annually thereafter.
PROJECTED ACCRUAL: A total of 1,000 patients will be accrued for this study.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing cyclophosphamide, fluorouracil and methotrexate in people with Breast Cancer, run by Scottish Cancer Therapy Network at 9 sites in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Nov 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in United Kingdom. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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.
Where can I read the original study information?
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 6 Nov 2013.
