本文对877例肺癌尸检材料作回顾性分析,详细讨论了瘤细胞类型、肿瘤部位、空洞形成、咯血和放疗的关系。认为(1)鳞状细胞类型比其他类型更多发生大量咯血(P=0.0002);(2)肿瘤位于主支气管部位者比周围型更多伴发不同程度咯血(P<0.0001);(3)鳞状细胞型肿瘤更倾向空洞形成;可伴发不同程度咯血。大咯血病例伴空洞形成(P<0.001),无咯血病例少见空洞形成。(4)放疗和咯血的关系。临床表现为大量咯血的半数以上、中量咯血的近1/3和无咯血的近1/4的病例中应用了放疗伴有或无其他治疗。大量咯血组与中量咯血组差别
This article retrospectively analyzed the autopsy materials of 877 cases of lung cancer, discussed in detail the relationship between tumor cell type, tumor site, void formation, hemoptysis and radiotherapy. It was considered that (1) squamous cell types had more hemoptysis than other types (P=0.0002); (2) tumors located at the main bronchus site had more hemoptysis with different degrees than peripheral types (P<0.0001); (3) Squamous cell tumors are more prone to void formation; they may be associated with varying degrees of hemoptysis. Hemoptysis was associated with the formation of voids (P<0.001), and the formation of voids was rarely seen in patients without hemoptysis. (4) The relationship between radiotherapy and hemoptysis. More than half of the hemoptysis, nearly one-third of hemoptysis, and nearly 1/4 of hemoptysis were clinically diagnosed with or without other treatments. The difference between massive hemoptysis and middle-dose hemoptysis
