Alterations in significant genes located on chromosome 7 - including epidermal growth factor receptor (EGFR) and also v-Raf murine sarcoma viral oncogene homolog B (BRAF) as a mitogen-activated protein kinase (MAPK) - combined or not with numerical imbalances of the whole chromosome (aneuploidy-polysomy) are crucial genetic events involved in the development and progression of malignancies. Identification of EGFR/BRAF-dependent specific somatic mutations and other mechanisms of deregulation (i.e., amplification) is critical for applying targeted therapeutic approaches [tyrosine kinase inhibitors (TKIs] or monoclonal antibodies (mAbs). Thyroid carcinoma is a specific pathological entity characterized by a variety of histological sub-types. Follicular thyroid carcinoma (FTC), papillary thyroid carcinoma (PTC), medullary thyroid carcinoma (MTC), and anaplastic thyroid carcinoma (ATC) represent its main sub-types. In the current review, we explore the role of EGFR/BRAF alterations in thyroid carcinoma in conjunction with the corresponding anti-EGFR/BRAF TKI-based novel therapeutic strategies for patients with specific genetic signatures.
位于7号染色体上的重要基因改变——包括表皮生长因子受体(EGFR)以及作为丝裂原活化蛋白激酶(MAPK)的v-Raf鼠肉瘤病毒癌基因同源物B(BRAF)——无论是否与整条染色体的数量失衡(非整倍体-多倍体)相结合,都是恶性肿瘤发生和发展过程中的关键遗传事件。识别EGFR/BRAF依赖性特异性体细胞突变和其他失调机制(即扩增)对于应用靶向治疗方法[酪氨酸激酶抑制剂(TKIs)或单克隆抗体(mAbs)]至关重要。甲状腺癌是一种具有多种组织学亚型的特定病理实体。滤泡状甲状腺癌(FTC)、乳头状甲状腺癌(PTC)、髓样甲状腺癌(MTC)和未分化甲状腺癌(ATC)是其主要亚型。在本综述中,我们探讨了EGFR/BRAF改变在甲状腺癌中的作用,并结合针对具有特定基因特征患者的基于抗EGFR/BRAF TKI的新型治疗策略。
