About this study

Official title: A Prospective, Randomized, Controlled Study to Evaluate Use of the PEAK PlasmaBladeTM 4.0 in Breast Lumpectomy

The purpose of this clinical study is to quantify the difference in thermal injury depth at the surgical margin in breast lumpectomy specimens excised with the PlasmaBlade; to subjectively assess histopathologic sample quality metrics; to examine the role that electrosurgical artifact may play in revision lumpectomy procedures; and to compare these endpoints to the standard of care (SOC) technology.

Read the detailed description

Lumpectomy is a surgical procedure performed to remove a localized mass of breast tissue that is suspicious for malignancy. The purpose of lumpectomy is to minimize the amount of tissue removed from the breast to retain normal breast architecture while simultaneously removing all of the suspected cancerous tissue. Typically, a scalpel is used for the skin incision and a traditional electrosurgical device is used to cut away any cancerous tissue.

The PEAK PlasmaBlade™ uses pulsed radiofrequency (RF) energy and a highly-insulated handpiece design to enable precision cutting and coagulation at the point of application. The PlasmaBlade has received FDA clearance for use in plastic, general, and ear, nose, and throat (ENT) surgery, and has demonstrated a significantly reduced thermal injury profile in incised tissue compared to traditional electrosurgical devices. It is hypothesized that this benefit may improve the pathological analysis of excised breast lumps.

This single site study was granted Institutional Review Board (IRB) approval and conducted between June 2009 and January 2011. Potential subjects were screened against the inclusion and exclusion criteria of the study protocol and were then required to provide informed consent prior to enrollment. Following enrollment, subjects were prospectively randomized to the SOC or PEAK PlasmaBlade study groups and scheduled for lumpectomy.

What participants receive

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

  • PEAK PlasmaBladeDevice

    Also called PlasmaBlade

    The entirety of the lumpectomy will be performed with the PEAK PlasmaBlade including the skin incision

  • Traditional Electrosurgery with scalpelProcedure or surgery

    Also called Scalpel, Electrosurgery, SOC

    The skin incision will be performed using a standard scalpel; the subcutaneous dissection will be performed with traditional electrosurgery using the Cut and Coagulation modes.

What is being measured

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

  1. Histological Metrics: Amount of Overlying Adherent Char on Slide; Damage to Tumor Epithelium; Effect of Electrosurgical Damage on Diagnostic Quality of Lumpectomy Specimen

    Overall histological quality score will be a composite of the histological metrics

    Measured: Intraoperative

Secondary outcomes (1)
  1. Operative Metrics: Operative Time, Estimated Blood Loss, Skin Scarring

    Measured: Intraoperatively and 1-2 weeks postoperatively

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted17 Aug 2009 (estimated)
  2. Study startJul 2009
  3. Primary completionFeb 2012
  4. Study completionFeb 2012

Why it stopped: Termination due to acquisition of PEAK Surgical by Medtronic

Questions about this trial

What is this clinical trial studying?

A study testing PEAK PlasmaBlade and Traditional Electrosurgery with scalpel in people with Breast Cancer, run by Medtronic Surgical Technologies 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?

The sponsor lists 5 inclusion and 7 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: stopped early, as of the sponsor's last update on 8 Jan 2013. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Jan 2013). 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?

Histological Metrics: Amount of Overlying Adherent Char on Slide; Damage to Tumor Epithelium; Effect of Electrosurgical Damage on Diagnostic Quality of Lumpectomy Specimen (time frame: Intraoperative). It is what the study was designed to measure, not a finding.

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 8 Jan 2013.
