Brief summary

This study will investigate the safety, feasibility, and immune response associated with cryoablation of early invasive breast cancer prior to lumpectomy. Based on mouse models, the investigators believe that cryoablation will initiate a stronger immune response relative to the control group. Consenting patients will be randomized to one of two arms: standard of care (control) or cryoablation (intervention). Participants will undergo a blood draw at the time of consent. Those in the control arm will continue with their standard of care lumpectomy. The intervention arm will receive cryoablation 2 weeks before their scheduled lumpectomy and undergo a second blood draw before the lumpectomy.

Interventions

PROCEDURECryoablation

Cryoablation is a non-surgical, minimally invasive freezing procedure used to destroy tumors. In the breast, cryoablation is performed under ultrasound guidance. Due to the analgesic properties of freezing, no IV sedation or anesthesia is required. After administration of local anesthetic, the physician makes a 2-3 mm incision and inserts needle-like cryoprobes into the tumor, commencing a number of freeze-thaw cycles. Then the probe is removed, pressure is applied to the area, and a bandage is placed. The patient leaves the office without stitches and minimal, if any, pain. Any residual pain after the procedure is routinely treated with over the counter analgesics such as acetaminophen.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of treatment-emergent adverse events [safety]1 day after cryoablationAssessed via phone call with participant and including any participant-reported adverse events, such as pain, bruising, bleeding, swelling, and skin changes
Immune responseOne week after lumpectomyImmunohistochemical analysis of biomarkers in blood and resected tissue
Cosmetic outcomeChange from one month to one year after lumpectomyChange in appearance based on distortion and volume loss of the breast
Tumor margin status [effectiveness]7-10 days after lumpectomyAssessment of whether excised tumor's margins are positive or negative for cancer, and whether re-excision is required
