据CA:A Cancer Journal for Clinicians在线版报道,美国癌症学会(ACS)发布指南,支持对部分高危个体采用小剂量CT扫描进行肺癌筛查,即应当与年龄55～74岁、有至少30包/年吸烟史、目前仍吸烟或戒烟不足15年、身体相对健康者讨论肺癌筛查问题。这部指南围绕全国肺部筛查试验(NLST)中采用的合格标准提出建议。由于获益与风险之间的平衡情况尚不明确,目前不推荐对年龄更小或更大者、一生中烟草暴露时间更短者,以及肺损伤较严重而需要吸氧者进行肺癌筛查。指南作者承认,如果患者的风险接近或超过NLST合格标准中的某一方面,而不符合标准的其他方面,临床医生就需要自己酌情做出判断。由于公立或私立保险机构很少覆盖首次小剂量CT肺癌筛查,决定提供筛查的临床医生有责任帮助患者决定是否要自费接受 According to the online report of CA: A Cancer Journal for Clinicians, the American Cancer Society (ACS) issued guidelines to support the screening of lung cancer in low-dose CT scans of some high-risk individuals, that is, with age 55-74 years, with at least 30 packs / Years of smoking history, smoking or smoking is still less than 15 years, the body is relatively healthy to discuss lung cancer screening. This guide provides recommendations on the eligibility criteria used in the National Lung Screening Test (NLST). As the balance between benefit and risk is not clear, screening for lung cancer is not currently recommended for younger or older people, shorter life-time exposure to tobacco, and more severe lung injury requiring oxygen inhalers. The authors acknowledge that clinicians need to exercise their discretion, if their risk approaches or exceeds one of the NLST eligibility criteria and does not meet other criteria. Because public or private insurance agencies rarely cover the first low-dose CT lung cancer screening, clinicians who decide to provide screening have a responsibility to help patients decide whether to accept it at their own expense
