Clinical Trial Summary

The purpose of this study will be to evaluate, in a multi-center setting, the ability of radiofrequency ablation (RFA) of breast cancer lumpectomy sites to extend the "final" negative margin and consequently decrease the rates of re-operation. During the initial breast conservation procedure (lumpectomy), immediately following routine surgical resection of the tumor, radiofrequency energy (RFA) is applied to the wall (bed) of the fresh lumpectomy cavity, thus extending tumor free margin radially beyond the volume of the resected specimen.

Type Measure Description Time frame Safety issue
Primary Estimate the re-excision rate for close (<3mm) or positive margins How many patients must go back for re-excision of margins Post-surgery (defined as 2 weeks after surgery, to allow time for pathology to be completed)
Primary Decrease local recurrence The patient will be followed closely from the time of surgery through a period of 5 years in order to assess the frequency of local recurrence, defined as a new diagnosis of cancer at or near the site of primary surgery. It is our thought that the addition of RFA to the standard surgical treatment will reduce the number of local recurrences. Monitor throughout 5 year follow-up
