About this study

Official title: A Phase I/II Trial to Evaluate Three Dimensional Conformal Radiation Therapy (3D-CRT) Confined to the Region of the Lumpectomy Cavity for Stage I and II Breast Carcinoma

RATIONALE: 3-dimensional conformal radiation therapy delivers a high dose of radiation directly to the tumor and may kill more tumor cells and cause less damage to normal tissue.

PURPOSE: Phase I/II trial to study the effectiveness of 3-dimensional conformal radiation therapy in treating women who have undergone lumpectomy and axillary node dissection for stage I or stage II breast cancer.

Read the detailed description

OBJECTIVES:

  • Determine the technical feasibility and reproducibility of three-dimensional conformal radiotherapy confined to the region of the lumpectomy cavity in women with stage I or II breast cancer.
  • Determine the cosmetic results in patients treated with this regimen.
  • Determine the complication rates in patients treated with this regimen.
  • Determine the local control rate in patients treated with this regimen.

OUTLINE: This is a multicenter study.

Patients undergo three-dimensional conformal radiotherapy twice daily for 5 days beginning within 8 weeks after surgery.

Patients are followed at 6 weeks, every 3 months for 1 year, every 4 months for 1 year, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 19-46 patients will be accrued for this study within 6.3 to 15.3 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing radiation therapy in people with Breast Cancer, run by Radiation Therapy Oncology Group at 2 sites in United States.

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 4 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

On the ClinicalTrials.gov record for NCT00068263, 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 4 Jan 2017.
