Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Capsular contraction is the one of the most common complications of both esthetic and reconstructive breast surgery, with high incidence after radiotherapy. The mechanism of the contraction is unclear, but is believed to be similar to the formation of hypertrophic scarring.

Dimethyl sulfoxide (DMSO) has demonstrated its use as an anti-inflammatory, anti-proliferative, and antibacterial agent.

The aim of this study is to test the effect of DMSO on the incidence and severity if capsular contracture after breast alloplastic reconstruction in irradiated patients.

We conduct a prospective randomized-control single-surgeon study in the tertiary academic Rabin Medical Center.

110 female candidates for mastectomy, radiotherapy and immediate two-stage reconstruction will be included. They will be divided into two groups: the DMSO treatment group, which will be treated according to our protocol, and the control group, that will be treated with the same protocol but with 0.9% saline instead.

Several measures will be taken, including: capsular contracture grading by two plastic surgeons, a VAS-score of breast pain, maximal capsular thickness (MCT) in sonography evaluation, and pathology examination of the capsule (biopsy will be taken during the second stage operation).

Rates and grades of capsular contracture evident clinically, radiologically and pathologically, will be evaluated and compared.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

DMSO treatment group

The treatment group will be exposed to DMSO according to our built protocol. On the seventh post-operative day, the patient will be guided to set 10 cc of DMSO soaked gauze compresses on the breast, twice a day for 20 minutes, for the term of 6 weeks. This treatment will be holed for 24 hours on tissue expander inflation dates. A repeated course of compresses will be taken after adjuvant radiotherapy, starting 24 hours after the last therapy.
