RASSF1A是同样位于3号染色体(3p21.3)上的一种抑癌基因,其同样与肺癌尤其是小细胞肺癌的发生密切相关,Huang等人[4]检索了Pubmed、Web of science、ProQest、Medline等数据库获得15篇文献,对RASSF1A超甲基化与肺癌患病风险进行大数据分析,证实两者之间的显著相关性。平均43.75%的肺癌病人有RASSF1A基因的超甲基化,其中1篇文献[5]中肺癌病人的RASSF1A甲基化检出率达94.44%,4篇文献[5-8]中肺癌RASSF1A甲基化检出率达80%以上。Wang等[9]同样用大数据分析RASSF1A基因甲基化与肺癌预后的关系,结果显示RASSF1A基因的甲基化是肺癌预后差的独立因素。
