世界卫生组织表明：中国癌症发病率世界第一 The World Health Organization shows that China ranks first in the world for cancer incidence 早期癌症治愈率大于90%，晚期治愈率小于10%！ 得了癌症并不可怕，关键是要...... 1 早发现 早诊断 2 3 早治疗 等于 延长寿命！ The recovery rate of early-stage cancer patients is greater than 90%, and forlater-stage patients it is less than 10% Cancer is no cause for alarm. The important thing is to detect, diagnose and treat it early on to prolong lifespan. 定期体检太重要 Regular checkups are extremely important 肺癌 我国发病率，死亡率均第一 肺癌占全部癌症死亡22.7% China ranks first in incidence and mortality of lung cancer patients in the world. Lung cancer accounts for 22.7% of the total cancer mortality rate.  以前：筛查肺癌靠胸片为主 现在：精准诊断，低剂量CT In the past, chest X-rays were the main tool for lung cancer screening Now, low-dose CT provides accurate diagnoses 科普时间到了，为你深扒一下 Time for science popularization, Give you a deep explanation 01 肺结节到底是什么鬼？ What is a lung nodule?  Lung nodules appear on CT scans as small, localised, quasi-circular, dense shadows of single or multiple counts. These nodules are singular, well-defined, opaque in images, with diameters of 3cm or less, and show no signs of hilar enlargement or pleural effusion. 02 报告常说的毛玻璃样结节又是什么？ What are the commonly reported GGNs (ground-glass nodules)?  毛玻璃样结节是一种影像学表现，是指局部结节样区域，肺的模糊度增加，表现为密度轻度增高的云雾状淡薄影或圆形结节，样子像磨砂玻璃一样，所以叫毛玻璃样结节。 GGNs are imaging manifestations that refer to a localised nodule-like area with increased lung ambiguity, showing as a nebulous faint shadow or round nodule with mildly increased density. They have the appearance of ground glass, hence the name 'ground-glass nodules’. 03 为什么我们要这么重视肺毛玻璃结节？ Why should we be vigilant of GGNs? 单纯磨玻璃样变恶性率高达59%-73%；混合性磨玻璃样病灶恶性率>93% 因为毛玻璃结节有可能是早期肺癌，我们不能放任其发展，及早的采取措施，防止向周围及远处脏器转移，甚至造成更为严重的后果。 The malignancy rate of pure GGNs is as high as 59%-73%; the malignancy rate of mixed GGN lesions is greater than 93%. Since GGNs can be early-stage lung cancers, we must intervene by taking early measures to prevent it from metastasizing to surrounding and distant organs, or leading to even more severe consequences.  患者对待毛玻璃结节的两种态度 随它去-体检没什么可做的 太紧张-过度就医 The two types of attitudes patients have towards ground-glass nodules Let it be – checkups are pointless Extremely anxious – excessively visiting the doctor 我们到底该怎么办？ What should we actually do? 很简单 It’s simple  1 找影像科诊断专家问诊 Inquire with a diagnostic radiologist 2 读片，片子就像是“罪犯现场”，专家寻找蛛丝马迹，不放过每个角落，每一病灶。 When reading radiographs, the radiograph is like the “crime scene”, the specialist searches for clues, and scours every nook and every lesion 3 解读片子，具体病例，具体分析、给予最终诊疗方案。 Study the radiograph –conduct a case-specific analysis – and provide the ultimate treatment plans 温馨提示：Tips 孤立的纯毛玻璃样肺结节：如果小于5mm，一年随访一次；如大于/等于5mm，3个月后复查CT，至少每年1次肺CT检查，观察结节大小性质变化。肺部毛玻璃结节一般主张大于8mm，结节形态欠规则，边缘存在分叶，毛刺等恶性征象就需要手术切除。 Solitary pure GGNs: if it is smaller than 5mm, follow up once a year; if it is 5mm or larger, CT scan re-examination after 3 months, and lung CT scan at least once a year to observe changes in size and nature. Excision is required if malignant symptoms appear, such as:GGNs in the lungs become larger than 8 mm, irregular nodule shapes, lobulated margins, and jagged edges. 低剂量肺CT公认为肺癌早期发现早诊断最有效的手段 Low-dose lung CT is widely recognized as the most effective tool for early detection and diagnosis of lung cancer 总结 /Summary/ 在癌症萌芽或者早期状态下，及时切断发展趋势，得癌不可怕，只要早发现，早治疗。 如果您有肺部结节问题的困惑，请及时联系我们的影像科李成州主任， 他可是火眼金睛的“神探”哦。 Put a stop to the growth of cancer before it starts, or while it’s still in its early stages. Getting cancer isn’t scary as long as it is detected and treated early. If you have questions or concerns regarding the Lung nodules , please get in touch with Dr. ChengZhou Li from our imaging department. He is an expert “detective” with a discerning eye.  专家介绍  影像科 【李成州】副主任医师 上海交通大学医学院附属同仁医院影像科行政副主任、核医学科（筹）主任 从事肺癌筛查和影像诊断、PET/CT应用工作，对肺癌的诊断和分期有丰富的经验。 擅长： 肺磨玻璃结节的诊断，肺小结节的鉴别诊断，PET/CT和PET/MR的临床应用。 特需门诊时间：周三上午     |
