Breast implants are extensively employed for both reconstructive and esthetic purposes. However, the safety of breast implants with textured surfaces has been questioned, owing to a potential correlation with anaplastic large-cell lymphoma and the recurrence of breast cancer. This study investigates the immune response elicited by different prosthetic surfaces, focusing on the comparison between macrotextured and microtextured breast implants. Through the analysis of intraoperatively harvested periprosthetic fluids and cell culture experiments on surface replicas, we demonstrate that macrotextured surfaces elicit a more pronounced chronic-like activation of leucocytes and an increased release of inflammatory cytokines, in contrast to microtextured surfaces. In addition, in vitro fluorescent imaging of leucocytes revealed an accumulation of lymphocytes within the cavities of the macrotextured surfaces, indicating that the physical entrapment of these cells may contribute to their activation. These findings suggest that the topography of implant surfaces plays a significant role in promoting a chronic-like inflammatory environment, which could be a contributing factor in the development of lymphomas associated with a wide range of implantable devices.
乳房植入物广泛应用于重建和美容目的。然而,由于其与间变性大细胞淋巴瘤和乳腺癌复发的潜在相关性,表面纹理的乳房植入物的安全性受到质疑。本研究调查了不同假体表面引起的免疫反应,重点比较了粗糙表面和微纹理乳房植入物。通过对术中采集的假体周围液和表面复制品的细胞培养实验分析,我们证明与微纹理表面相比,粗糙表面会引起白细胞更明显的慢性样激活和炎症细胞因子的释放增加。此外,白细胞的体外荧光成像显示淋巴细胞在粗糙表面的腔室内积聚,表明这些细胞的物理捕获可能有助于其激活。这些发现表明,植入物表面的拓扑结构在促进类似慢性的炎症环境中起着重要作用,这可能是与各种植入式设备相关的淋巴瘤发展的一个因素。
