Radiofrequency Ablation in Treating Patients With Early Invasive Breast Cancer or Ductal Carcinoma in Situ
A study testing conventional surgery, neoadjuvant therapy and radiofrequency ablation in people with Breast Cancer, run by University of California, Davis at 1 site in United States.
Trial summary
RATIONALE: Radiofrequency ablation uses a high-frequency, electric current to kill tumor cells. Giving radiofrequency ablation before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Read more about this study

About this study
Official title: A Pilot Study of Radiofrequency Ablation of Early Invasive and In Situ Breast Cancer
RATIONALE: Radiofrequency ablation uses a high-frequency, electric current to kill tumor cells. Giving radiofrequency ablation before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
PURPOSE: This clinical trial is studying how well radiofrequency ablation followed by surgery works in treating patients with early invasive breast cancer or ductal carcinoma in situ.
Read the detailed description
OBJECTIVES:
Primary
- Determine the effectiveness of radiofrequency ablation (RFA), in terms of amount of tumor coagulated and viable cell count, in patients with early invasive breast cancer or low- or intermediate-grade ductal carcinoma in situ.
Secondary
- Determine the size, configuration, and pathological features of human breast tumors after treatment with RFA.
- Determine whether RFA energy applied to breast cancer will result in cancer cell death.
- Determine whether tumor-free margins are achieved by RFA in these patients.
- Determine the rate of acute toxicities to skin after surgery in patients treated with this regimen.
OUTLINE: This is a pilot study.
- Pre-radiofrequency ablation (RFA) procedures: Patients undergo staging by MRI assessment to determine the size of their tumor. Patients with nonpalpable lesions must undergo placement of a metallic clip in the center of their tumor and a hook wire to guide surgical excision by intraoperative ultrasound imaging. Patients with invasive breast cancer undergo axillary lymph node dissection or sentinel lymph node biopsy (SLNB) for axillary lymph node staging. Patients with ductal carcinoma in situ proceed directly to RFA/resection since they do not require axillary staging.
- RFA: Patients undergo RFA comprising insertion of a multiple-needle electrode into the breast tumor under direct guidance of ultrasonography and the metallic clip placed preoperatively in the lesion.
- Surgical resection of RFA area: After RFA is completed, the electrode is removed and patients undergo wide local excision of the residual tumor or mastectomy.
After completion of study therapy, patients are followed periodically for up to 4 months.
PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
conventional surgeryProcedure or surgery
Standard of care lumpectomy or mastectomy following RFA
neoadjuvant therapyProcedure or surgery
Standard of care lumpectomy or mastectomy following RFA
radiofrequency ablationProcedure or surgery
Also called RFA
A small diameter needle is inserted through the skin and directly into the tumor for the purpose of supplying RF current. Initial power of the RF generator will start at 5-10 watts. The power will increase by 5-10 watts every minute until impedance of the system automatically stops the RF treatment.
| Study group | Role | What they receive |
|---|---|---|
| RFA prior to surgery | Experimental | Not described Receives: Procedure: conventional surgery; Procedure: neoadjuvant therapy; Procedure: radiofrequency ablation |

Questions about this trial
What is this clinical trial studying?
A study testing conventional surgery, neoadjuvant therapy and radiofrequency ablation in people with Breast Cancer, run by University of California, Davis 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 9 inclusion and 6 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 29 Mar 2010. 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.
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 and proportion of patients with viable cancer cells remaining in the resected specimen as measured by enzyme cell viability analysis and amount of tumor coagulated at post-treatment biopsy (time frame: At completion of study). 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 29 Mar 2010.
