CT筛查有助于发现可治性肺癌
Dr. Claudia I. Henschke, from Weill Cornell Medical Center in New York, and her group obtained results for nearly 29,000 people who underwent CT screening between 1993 and 2004. A total of 464 cases of lung cancer were screen diagnosed, including 436 non-small cell lung cancers and 28 cases of small cell lung cancer.
根据纽约科那儿医学中心克劳德博士的研究，在1993年至2004年的29000例肺部CT筛查中，发现464例肺癌，包括436例非肺小细胞癌和28例肺小细胞癌。
Among non-small cell lung cancer cases, the proportion of cases with no metastases ranged from 91% of patients in whom the tumor was 15 mm or smaller, to 55% of those with tumors 36 mm or greater.
在非肺小细胞癌中，肺癌小于15毫米的病例91%的没有转移，36mm以上的病理没有转移的约55%或更高。
The lymph node status was positively associated with tumor size for solid nodules -- that is, the nodule obscured the entire lung parenchyma within it -- and "suggestive" for part-solid tumors. However, the relationship was absent for nonsolid nodules, which were diagnosed as noninvasive adenocarcinomas or adenocarcinoma-mixed subtype with a small invasive component.
对于实行结节性病灶，癌的大小与淋巴结状态呈正相关，淋巴结增大提示癌可能为部分实性。但是对于非实性肿瘤，例如非侵犯性腺癌，或者非侵犯性腺癌与侵犯性小细胞癌的混合型中，不存在这种关系。
All of the small cell cancers presented as solid nodules. For these, the proportion of cases with no metastases was 67% for tumors 25 mm or less versus 23% for larger tumors.
所有的小细胞癌都表现为实性细胞癌。对于25mm以下的肿瘤，没有发生转移的病例占到67%，更大的肿瘤不到23%.
"The pattern confirmed herein suggests the usefulness of finding latent cancers at small sizes," the authors point out. "Most lung cancers without evidence of lymph node metastases are curable, with the curability rate being higher at smaller sizes."
“这一病变模式显示了发现隐匿性小体积肺癌的重要性”，作者指出“没有淋巴结转移证据的肺癌是可以治愈的，对于具有淋巴结转移征象的肺癌，病变越小，越容易治愈。”
