中新网3月25日电 据美国世界新闻网编译报道，医学界对白人和非裔美国人罹患癌症的死亡率差异探索已久，但针对亚裔美国人的相关研究寥寥无几。不过波士顿布里翰妇女医院(Brigham and Women’s Hospital，BWH)的新研究显示，亚裔美国人罹患癌症的存活率远高于白人癌症病患。
BWH在“国家癌症研究院期刊”(Journal of the National Cancer Institute)发表的最新研究发现，亚裔美国人因癌症相关疾病致命的死亡率远低于白人。
研究作者之一的泌尿科医师陈国琰(Quoc-Dien Trinh，音译)指出，尽管亚裔美国人仅占美国总人口的5%，但该群体是美国发展最快的族裔。他们的研究不但聚焦亚裔美国人罹患癌症的存活率，更将亚裔美国人分为华裔、菲律宾裔、夏威夷裔、日裔、韩裔、东南亚裔及越南裔等。
陈国琰及研究同事对罹患各类癌症的250多万名病患的数据进行分析后，发现亚裔群体不仅患癌致死的机率低于白人，其内部也存在较大差异。日裔、菲律宾裔和南亚裔癌患的存活率远远高于白人。但日裔在前列腺癌、乳腺癌和直肠癌的存活率更佳，菲律宾裔更能抵御前列腺癌和肺癌，南亚裔则为肺癌和直肠癌。
然而，夏威夷裔及韩裔的“抗癌”却与白人相差无异，华裔和越南裔也只在肺癌的存活率上高于白人。
该研究虽未指出亚裔癌患存活率高于白人的原因，但给未来的相关研究打下基础，更有利于科学家找出存在差异的基因或文化原因。(罗晓媛)

Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
