【摘要】 目的探讨有咳血症状肺癌CT表现和病理学类型特点。方法分析手术或支气管纤维镜证实的50例有咳血症状肺癌患者病史和CT资料,50例无血痰症状的肺癌作为对照组。研究两者的病理类型、发生部位、大小、空洞有无等差异。结果研究组(A)和对照组(B)病理类型在腺癌和鳞癌的发生比例分别是48%,26%和23%,31%;两组患者在腺癌发病率上相差显著(P<0.05)。中央型肺癌和周围型肺癌在两组中的比例分别是54%,50%和46%,50%;相差无显著意义(P>0.05)。两组肺癌平均大小分别是30±2.54mm和32±1.93mm;两组肺癌空洞的发生率分别是18%和15%;其大小和空洞发生率均无显著差异(P>0.05)。结论有咳血症状的肺癌与其病理类型有关而与其生长部位、大小及是否出现空洞无关。更多还原

【Abstract】 Objective To explore the CT features and histological types of haemoptysis patients with primary lung cancer. Methods 50 haemoptysis patients (group A) with primary lung cancer confirmed by bronchoendoscopic examination or operation were analyzed. 50 cases of primary lung cancer without haemoptysis were studied as the contrast group (group B). The tumor size, shape, cavity, as well as location and pathological type were compared. Results The proportions of adenocarcinoma and squamous cell carcinoma were 48%, 26% in Group A and 23%, 31% in Group B respectively. The occurrent rate of adenocarcinoma showed significant difference between Group A and B(P>0.05). The proportion of central lung cancer and peripheral lung cancer were 54%, 50% and 46%, 50% in Group A and B respectively. No significant difference occurred in both two types of cancer between two groups (P>0.05). The average size of cancer mass were 30±2.54 mm in Group A and 32 ±1.93mm in group B. The occurrence rate of lung cavity was 18% and 15% respectively in Group A and B. No significant difference existed in size and the occurrence rate of lung cancer mass between Group A and B (P>0.05). Conclusion Haemoptysis in patients of primary lung cancer was correlated with pathology type, instead of location, size and cavities.更多还原
