新HPV疫苗能预防80%宫颈癌

2015-05-15 佚名 生物谷

美国的一项新研究表明,在儿童十二岁之前给他们注射最新的人乳头瘤病毒(HPV)疫苗能有80%的概率预防宫颈癌。 研究表明,该疫苗(被称为9-Valent)能预防9中不同的人乳头瘤病毒株,同时也可能能预防19,000种其他癌症,包括肛门癌和阴茎癌。新的HPV疫苗相比前一代而言,其保护作用提升了11%。研究还发现,这种疫苗可以预防5.7%的咽喉癌,而咽喉癌则是常见癌症中第二个最与HPV相关的癌症。

美国的一项新研究表明,在儿童十二岁之前给他们注射最新的人乳头瘤病毒(HPV)疫苗能有80%的概率预防宫颈癌。

研究表明,该疫苗(被称为9-Valent)能预防9中不同的人乳头瘤病毒株,同时也可能能预防19,000种其他癌症,包括肛门癌和阴茎癌。新的HPV疫苗相比前一代而言,其保护作用提升了11%。研究还发现,这种疫苗可以预防5.7%的咽喉癌,而咽喉癌则是常见癌症中第二个最与HPV相关的癌症。

美国疾病控制中心和美国Cedars-Sinai Samuel Oschin癌症防治中心检测了从1993年到2005年2670位癌症患者的HPV的DNA样本。他们试图找出有多少癌症病例是由上文提到的9种HPV引起的。

癌症防治中心的该项研究的资深领导者Marc T. Goodman在一次新闻发布会上说:“这是全球第一个关于这方面的研究,该研究不仅减少了全球癌症负担,也在一定程度上指导了儿童接种疫苗。我们还发现了70%的病人的口咽癌组织样本中含有HPV,这比以往研究中发现的都要多。可能是因为性行为的变化,如口交的增多。”而研究结果则已发表在《美国国家癌症研究所杂志》上了。

如果你已经接种了其他HPV疫苗,也无须担心。早些时候的研究已经表明,这些疫苗在预防各种癌症上都有着不小的成效,只是新的9-Valent疫苗能多提供11%的保护。不过,对抗癌症的保护自然是多多益善的。
