Abstract

Squamous cell carcinomas of the lung, head and neck, esophagus, and cervix account for more than two million cases of cancer per year worldwide with very few targetable therapies available and minimal clinical improvement in the past three decades. Although these carcinomas are differentiated anatomically, their genetic landscape shares numerous common genetic alterations. Amplification of the third chromosome's distal portion (3q) is a distinguishing genetic alteration in most of these carcinomas and leads to copy-number gain and amplification of numerous oncogenic proteins. This area of the chromosome harbors known oncogenes involved in squamous cell fate decisions and differentiation, including , , , and . Furthermore, novel targetable oncogenic kinases within this amplicon include , , , and . TCGA analysis of these genes identified amplification in more than 20% of clinical squamous cell carcinoma samples, correlating with a significant decrease in overall patient survival. Alteration of these genes frequently co-occurs and is dependent on 3q-chromosome amplification. The dependency of cancer cells on these amplified kinases provides a route toward personalized medicine in squamous cell carcinoma patients through development of small-molecules targeting these kinases.

摘要

肺、头颈部、食管和宫颈的鳞状细胞癌每年在全球导致超过 200 万例癌症病例,可用的靶向治疗方法很少,在过去三十年中临床改善甚微。尽管这些癌在解剖学上有所不同,但它们的遗传景观有许多共同的遗传改变。第三号染色体远端部分(3q)的扩增是这些癌中的一个显著的遗传改变,导致许多致癌蛋白的拷贝数增加和扩增。染色体的这一区域包含已知的参与鳞状细胞命运决定和分化的致癌基因,包括、、、和。此外,这个扩增子内新的可靶向致癌激酶包括、、和。TCGA 对这些基因的分析表明,在超过 20%的临床鳞状细胞癌样本中存在扩增,与患者总体生存率的显著下降相关。这些基因的改变经常同时发生,并依赖于 3q 染色体的扩增。癌细胞对这些扩增激酶的依赖性为鳞状细胞癌患者通过开发针对这些激酶的小分子提供了一条个体化医疗的途径。
