Breast Capsular Contracture Clinical Trial
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.
