摘要

相关性:肺癌相关的慢性阻塞性肺疾病(COPD)在吸烟患者中很常见。计算机断层扫描(CT)在发现肺癌,评估区域性肺实质破坏和COPD气道重塑方面至关重要。本研究旨在确定COPD合并肺癌的CT特征。方法:本回顾性研究包括56例40岁以上、吸烟史10年及以上、疑似慢性阻塞性肺病患者的胸部CT检查。46.43%的患者有肺癌合并COPD的CT征象。结果:肺癌患者中桶状胸(19.23%)、马刀鞘气管(7.69%)、支气管扩张(15.38%)较少见。96.15%诊断为隔旁肺气肿和小叶中心肺气肿,其中大泡型占73.33%。支气管管腔狭窄和管壁增厚在所有叶状支气管、段状支气管和亚段状支气管中均有发现。结论:肺膈旁、小叶中心肺气肿及肺上叶大泡是COPD合并肺癌患者的主要CT表现。叶支气管、节段支气管、亚节段支气管均可见管腔狭窄、壁增厚。

COMPUTED TOMOGRAPHY FEATURES OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE ASSOCIATED WITH LUNG CANCER
Relevance: Chronic obstructive pulmonary disease (COPD) associated with lung can-cer is common in smoking patients. Computed tomography (CT) is vital in detecting lung cancer, assessing regional lung parenchymal destruction, and airway remodeling in COPD. The study aimed to determine the CT features of COPD associated with lung cancer. Methods: This retrospective study included chest CT exams of 56 patients over the age of 40 with a smoking history of 10 years and more and with suspected COPD. 46.43% of patients had CT signs of lung cancer associated with COPD. Results: Barrel-shaped chest (19.23%), saber-sheath trachea(7.69%), and bronchiecta-sis (15.38%) were less common in patients with lung cancer. 96.15% were diagnosed with paraseptal and centrilobular emphysema, bullae – 73.33%. Bronchial narrowing of the lumen and wall thickening were identified for all lobar bronchus, segmen-tal bronchus, and subsegmental bronchus. Conclusion: Paraseptal and centrilobular emphysema and bullae in the upper lobes of the lungs were predominant CT features in patients with COPD associated with lung cancer. Lumen narrowing and wall thickening of lobar bronchus, segmental bronchus, and subsegmental bronchus were also revealed.
