肺癌筛查中常见过度诊断最新出版的美国《放射学》杂志一项研究报告指出,肺癌CT检查过度诊断较为普遍,用胸部CT筛查高危人群特别是女性患者可能导致肺癌病例的过度诊断。研究人员连续5年对高风险人群进行年度胸部CT检查,对新增和既有肿瘤病灶,包括肿瘤大小、形态、位置、形态变化、肿瘤生长速率进行了评价。 Common over-diagnosis in lung cancer screening A new study published by the American Journal of Radiology states that over-diagnosis of lung cancer by CT is more common. Chest CT screening of high-risk groups, especially female patients, may lead to overdiagnosis of lung cancer. Researchers conducted annual chest CT scans of high-risk groups for 5 consecutive years to evaluate new and existing tumor lesions, including tumor size, morphology, location, morphological changes, and tumor growth rate.
