This randomized pilot clinical trial studies how well image guided cryosurgery works in managing post mastectomy pain syndrome in patients that have undergone mastectomy, partial mastectomy, lumpectomy, or breast reconstruction. Image guided cryosurgery involves using a computed tomography (CT) scan to help guide a needle inserted through the skin into the targeted nerve, and uses a freezing effect that may work better in reducing the pain felt from the mastectomy, partial mastectomy, lumpectomy, or breast reconstruction.


I. To establish the validity of the cryoablation comparative peripheral nerve block approach in patients with post-mastectomy pain syndrome (PMPS) and to compare the response to cryoablation to that of a therapeutic peripheral nerve block on improvements in PMPS symptoms over a follow-up period of 6-months.

I. Evaluating differences in health-related quality of life variables over the course of 6 months in patients with PMPS that undergo cryoablation compared to those that receive a therapeutic peripheral nerve block injection (tPNB).

I. To support all efficacy conclusions, complementary analyses will be performed to determine if there are differences in the safety and tolerability profiles between cryoablation and tPNB.
II. To empower clinicians and researchers with a set of thresholds that can be used to determine which patients have responded to treatment.

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP 1: Patients undergo CT and then undergo cryosurgery for the targeted nerve over 25-45 minutes.

GROUP 2: Patients undergo CT and then receive injection of bupivacaine hydrochloride and betamethasone into the targeted nerve.

After completion of study treatment, patients are followed up for 180 days.
