Most patients with malignant pleural mesothelioma (MPM) have a history of exposure to carcinogenic asbestos fibers, and the latent period of this disease is more than 40 years. Therefore, the numbers of the patients are now still increasing. Cetuximab is a chimeric mouse-human antibody directed against the extracellular domain of EGFRand has been shown remarkable effects for colorectal cancer and head and neck cancer. However, no published in vitro or in vivo studies have focused on the effect of cetuximab against MPM. In the present study, we found that cetuximab has potent anti-tumor activity against MPM in combination with the methods to enhance its immunological function, antibody-dependent cellular cytotoxicity (ADCC) activity. Our data indicate the important role of ADCC activity in the mechanism of action of cetuximab and underscore the promising potential of cetuximab as a new class of therapeutic agent for use against MPM.

大多数恶性胸膜间皮瘤（MPM）的患者都有暴露于致癌石棉纤维的史，这种疾病的潜在时期已超过40年。因此，现在患者的人数仍在增加。西妥昔单抗是一种针对Egfrand的细胞外结构域的嵌合小鼠人类抗体，对结直肠癌和头颈癌的影响很大。但是，没有发表的体外或体内研究都集中在西妥昔单抗对MPM的影响。在本研究中，我们发现西妥昔单抗具有对MPM的有效抗肿瘤活性，并结合增强其免疫功能，抗体依赖性细胞毒性（ADCC）活性的方法。我们的数据表明，ADCC活性在西妥昔单抗的作用机理中的重要作用，并强调了西妥昔单抗作为用于MPM使用的新型治疗剂的有希望的潜力。
