Trial summary

In this protocol we combine two available and reliable treatments - lumpectomy and RFA. This combination method will provide for excision of the cancer as routinely accomplished and ablation of the cancer bed (lumpectomy site) to ensure negative margins without removing large volumes of tissue.

About this study

In this protocol we combine two available and reliable treatments - lumpectomy and RFA. This combination method will provide for excision of the cancer as routinely accomplished and ablation of the cancer bed (lumpectomy site) to ensure negative margins without removing large volumes of tissue. This combined open technique will allow for full histologic analysis of the primary tumor and margin. Because no extra tissue is removed from the breast to generate negative margins it will result in better cosmesis than re-excision to obtain negative margins.

Read the detailed description

While RFA alone is not approved for tumor destruction in breast it is FDA-approved for ablation of soft tissue after the breast cancer is removed. This study seeks to remove the tumor and then ablate a tumor-free zone (margin) of tissue around the lumpectomy site instead of removing more tissue. The primary short-term goal is to obviate the need for re-excision in the event of close or positive margins (< 3 mm) which occurs on average in ~40 percent of the cases. Permanent pathology is only an estimation of margin status since 90% of recurrences occur at the site of the original lumpectomy. RFA ensures a sterilized margin regardless of the accuracy of the permanent pathology.

What participants receive

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

  • AngioDynamics (previously RITA Med,Inc) radiofrequency delivery system (consisting of a generator and Starburst XL probe)Device

    Generator is connected to a single use probe. Probe is inserted into the lumpectomy cavity and heated to 100 degrees Celsius and held there for 15 minutes, after which probe is removed.

What is being measured

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

  1. Number of Patients Requiring 2nd Surgery for Close or Positive Margins

    A "close" surgical margin implies that cancer cells are found on pathology to be very close to the surgical margin, and a "wide" surgical margin implies the tumor exists far from the cut edge or the surgical margin. For this study, we defined "close" as less than 3 mm.

    Measured: Margins assessed at Final Pathology, approximately 1 week post-RF surgery

Secondary outcomes (1)
  1. Recurrence of Breast Cancer at Prior Site of Disease

    Measured: Until study end (2 years)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing AngioDynamics (previously RITA Med,Inc) radiofrequency delivery system (consisting of a generator and Starburst XL probe) in people with Cancer of the Breast, run by University of Arkansas 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 15 inclusion and 10 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 24 Nov 2015. 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?

Yes. Results are posted in the registry (first posted 6 Oct 2015). 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?

Number of Patients Requiring 2nd Surgery for Close or Positive Margins (time frame: Margins assessed at Final Pathology, approximately 1 week post-RF surgery). 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 NCT00571987, 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 24 Nov 2015.
