Clinical Trial Summary

The use of breast implants, both in cosmetic and restorative surgery, is common. It is a device consisting of a silicone elastomer envelope and the container of which may be silicone gel or saline. They can be texturing carriers (roughness) on the surface of their envelope. If silicone is considered inert and biocompatible, several phenomena should be noted: - Implant placement results in the formation of a periprosthetic capsule which is the product of the inflammatory reaction and will isolate it from adjacent breast tissue - The periprosthetic capsule and adjacent breast tissue are chronically exposed to implant silicone. - Silicone in implants, even intact, has been shown to diffuse through the shell into the periprosthetic compartment and adjacent breast tissue - There is a phenomenon of erosion of the surface of the implants, particularly textured, responsible for the release of silicone particles within the periprosthetic capsule - The rupture of the prosthetic envelope is a dreaded complication, due to the alteration of the aesthetic result and the possibility of leakage of silicone gel - Since 2016, macrotextured implants have been implicated in the occurrence of anaplastic large cell lymphoma associated with breast implants (LAC-AIM) The presence of silicone in contact with tissues seems to promote an inflammatory environment, and this phenomenon seems increased if the implant is textured. Chronic inflammation induced by these devices can therefore have harmful consequences in the long term. INFLAMA study interested in the consequences of the presence of a silicone implant on local inflammatory phenomena within the periprosthetic capsule.

Type Measure Description Time frame Safety issue
Primary characteristics of inflammation according to the importance of silicone exposure Verify the existence of a relationship between the characteristics of inflammation and the importance of silicone exposure (intact implant, implant rupture in serum or silicone) at the genomic molecular level, by analyzing the level of expression of genes related to the extracellular matrix and inflammation within a periprosthetic capsule fragment immediately after surgery
Secondary characteristics of inflammation according to the type of texturing of implants Check the existence of a relationship between the characteristics of inflammation and the type of texturing of implants (smooth, micro textured or macro textured), on the genomic molecular level, by analyzing the level of expression of genes related to the extracellular matrix and inflammation within a periprosthetic capsule fragment. immediately after surgery
Secondary Characterize the inflammatory reaction within the periprosthetic capsule histologically, depending on the importance of silicone exposure. immediately after surgery
Secondary Characterize the inflammatory reaction within the periprosthetic capsule histologically, according to texturation. immediately after surgery
Secondary Identify a possible relationship between the characteristics of inflammation and the presence of a clinical shell. immediately after surgery
