About this study

Official title: Hypo-Fractionated Conformal Radiation Therapy to the Tumor Bed After Segmental Mastectomy

The purpose of this study is to determine whether high dose of radiation therapy (RT) are effective over standard 6-week radiation treatment in patients with breast cancer

Read the detailed description

Hypo-fractionation (several large fractions as the only radiation treatment) for breast cancer irradiation was common in the forties and 50s and, while very successful in achieving tumor control, was found to leave significantly inferior cosmetic results due to severe fibrosis and telangiectasia compared to those obtained with multiple fraction regimens (38-40). These complications were due to the use of very large fields, with the inclusion of a large proportion of uninvolved skin and tissue surrounding the tumor.

Based on these assumptions, a few large fractions can be safely delivered to breast cancers provided that 1) the target volume is sufficiently small and 2) the radiation technique assures maximum sparing of the surrounding normal tissue. Conformal RT to the tumor bed of T1 breast cancers satisfies both requirements.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 6 Gy/ fractionRadiation

    All patients will be treated with 6 Gy (measure of radiation dose) /fraction (each radiation session) delivered in 5 fractions over a 2 week period for a total dose of 30 Gy.

    In addition to routine care, patients may receive antihormonal drugs as part of your base line treatment.

What is being measured

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

  1. Number of participants with treatment-related adverse events as assessed by CTCAE v4.0

    Measured: Up to 5 years

Secondary outcomes (2)
  1. TGF-beta 1 determinations

    Blood specimens will be collected by venipuncture, before starting treatment, immediately after the last treatment fraction

    Measured: From baseline to up to 4 weeks

  2. Ultrasound for target localization

    Ultrasound is ideal for imaging soft tissues unobstructed by bone and has been used successfully in conjunction with the treatment of prostate cancer to verify compliance between the daily location of the prostate and the planned location with respect to the treatment linear accelerator. By using ultrasound to image the post-operative tumor bed of the breast in "real-time", the operator may automatically align the tumor bed with treatment machine on each day of treatment

    Measured: up to 4 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing 6 Gy/ fraction in people with Breast Cancer, run by NYU Langone Health at 1 site 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?

The sponsor lists 7 inclusion and 4 exclusion criteria. 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 21 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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.

What does the primary outcome measure?

Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 (time frame: Up to 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 NCT02883985, which also lists 1 linked publication.

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 21 Dec 2018.
