About this study

Official title: Phase III Trial of Tamoxifen Alone vs. Tamoxifen Plus Radiation Therapy for Good Risk Duct Carcinoma In-Situ (DCIS) of the Female Breast

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen by the tumor cells. It is not yet known if radiation therapy is more effective than observation, with or without tamoxifen, in treating ductal carcinoma in situ.

PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with that of observation, with or without tamoxifen, in treating women who have ductal carcinoma in situ.

Read the detailed description

OBJECTIVES:

  • Compare the efficacy of whole breast radiotherapy vs observation with or without optional tamoxifen in decreasing or delaying the appearance of local failure (both invasive and in situ) and preventing the need for mastectomy in women with good-risk ductal carcinoma in situ (DCIS) of the breast.
  • Compare distant disease-free survival of patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to age (under 50 vs 50 and over), final path margins (negative vs 3-9 mm vs at least 10 mm), mammographic size of primary (no greater than 1 cm vs greater than 1 cm to 2.5 cm), nuclei grade (low vs intermediate), and tamoxifen use (yes vs no). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients undergo observation and may receive optional oral tamoxifen once daily (at the discretion of the physician) for 5 years.
  • Arm II: Beginning within 12 weeks after final surgery, patients receive radiotherapy to the whole breast once daily, 5 days a week, for 3.5-5.5 weeks. Patients may receive optional tamoxifen as in arm I.

Patients are followed every 3 months for 1 year, every 6 months for 2 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 1,790 patients will be accrued for this study within 6 years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Local recurrence (e.g., invasive or noninvasive recurrence)

    Measured: From randomization to date of local failure in the treated breast or last follow-up. Analysis occurs after all patients have been potentially followed for 5 years.

Secondary outcomes (4)
  1. Overall survival

    Measured: From randomization to date of death or last follow-up. Analysis occurs after all patients have been potentially followed for 5 years.

  2. Time to distant metastasis

    Measured: From randomization to date of distant metastasis or last follow-up. Analysis occurs after all patients have been potentially followed for 5 years.

  3. Invasive local recurrence

    Measured: From randomization to date of invasive local failure in the treated breast or last follow-up. Analysis occurs after all patients have been potentially followed for 5 years.

  4. Salvage mastectomy rate

    Measured: Analysis occurs after all patients have been potentially followed for 5 years.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing tamoxifen citrate, adjuvant therapy and radiation therapy in people with Breast Cancer, run by Radiation Therapy Oncology Group at 369 sites in 2 countries.

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 25 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 369 sites in United States, Canada. 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.

What does the primary outcome measure?

Local recurrence (e.g., invasive or noninvasive recurrence) (time frame: From randomization to date of local failure in the treated breast or last follow-up. Analysis occurs after all patients have been potentially followed for 5 years.). 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 NCT00003857, which also lists 2 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 25 May 2022.
