Nature杂志1月28日发表了迄今为止最全面的头颈癌基因组测序分析结果。癌症基因组图谱计划(Cancer Genome Atlas,TCGA)的科学家们揭示了人乳头瘤病毒(HPV)和抽烟对头颈癌的影响,比较了头颈癌与其它癌症的异同,为头颈癌的诊断和治疗提供了新的方向。

HPV是美国最常见的性传播病毒之一,HPV引发的头颈癌正在逐年增加。FDA批准的HPV疫苗能够预防HPV感染,但病毒感染与癌症发展之间往往存在很长的时间间隔。人们亟需理解HPV阳性头颈癌的分子改变,并在此基础上开发新的治疗策略。

“我们揭示了HPV阳性和HPV阴性头颈癌之间的差异,有助于反思目前对头颈癌的处理方式。”文章的资深作者,北卡罗来纳大学的副教授D. Neil Hayes说。

研究人员对279例未经治疗的头颈鳞状细胞癌(HNSCC)进行了基因组分析,其中大多数样本是口腔癌(61%)和喉癌(26%),约80%的样本来自于吸烟者。

这些头颈癌样本只有25%与HPV感染有关。TCGA研究人员发现,HPV引起的肿瘤中存在FGFR3和PIK3CA基因突变,这些突变也出现在与抽烟有关的肿瘤中。EGFR(表皮生长因子受体)基因在HPV阴性肿瘤中频繁突变,但在HPV阳性肿瘤中很少出现异常。这样的信息有助于人们开发新抗癌药物和生物学指标。

研究表明,超过70%的头颈癌存在生长因子受体(EGFR, FGFR, IGFR, MET, ERBB2, DDR2)、信号分子(PIK3CA, HRAS)和细胞分裂调控(CCND1)基因的突变。这些基因在细胞生长和增殖中起到了重要作用,已经成为了药物开发的靶标。

研究人员还发现了头颈癌抵抗药物的新线索。在与抽烟有关的头颈癌中,癌症耐药性与FADD和BIRC2额外拷贝、CASP8基因突变或缺失有关,涉及了程序性细胞死亡。在与HPV有关的癌症中,癌症抗性与TRAF3基因缺失、E2F1基因额外拷贝有关。

这项研究将头颈癌与其它癌症进行了比较,揭示了癌症发展的通用路径,发现了潜在的治疗机会。“头颈癌的基因组与肺鳞状细胞癌和宫颈癌很相似,这让我们很意外。这些癌症形成于不同的器官,但在遗传学上却很类似,”Dr. Hayes说。这些相似的遗传学异常,发生在帮助细胞应对损害和压力的通路中。

这项大规模癌症分析有助于建立各种头颈癌的基因组图谱,为未来的头颈癌研究和治疗提供了重要的新线索。
