Capsular contracture is the most common serious breast surgery complication. The cause of capsular formation remains unknown, but chronic inflammation is commonly considered to cause excessive fibrosis. Curcumin has anti-inflammatory effects and thus can relieve the symptoms of inflammatory diseases, as demonstrated in animal studies. This study aimed to evaluate the effects of curcumin on the fibrous envelope covering silicone implants in a rat model.
Two solid 1.8-cm oval-shaped silicone implants were placed beneath both sides of the back in 20 Sprague-Dawley rats. The control group included 10 rats that were fed a normal diet (group A), while the experimental group (group B) included the remaining 10 rats that were fed ground curcumin. En bloc excision was conducted at 8 postoperative weeks. Capsular thickness and inflammatory cell distribution were examined using a fixed tissue sample.
Gross findings and histologic differences between the groups were observed. The experimental group had a significantly lower mean total capsular thickness than the control group (177.4±31.4 μm vs. 145.9±32.5 μm, P=0.007). A significant decreasing tendency was found in several inflammatory cells in the experimental group (7,070±744.3/mm2 vs. 2,640±301.7/mm2, P=0.001).
Curcumin significantly reduced the inflammatory reaction, and will help to lower the risk of capsular contracture. Long-term studies are required to determine whether this hypothesis can provide a basis for a viable therapeutic strategy to reduce capsular contracture.
