目的: 本研究探讨老年人及中青年人细支气管肺泡癌( BAC) 的临床症状、诊断、影像学特点，治疗方
案及预后。方法: 用统计学方法回顾性分析北京世纪坛医院2001－10 ～ 2012－06 期间收治的经病理证实的55 例
细支气管肺泡癌。结果: 本组病例男女之比1． 0: 1． 2，老年人占64%( 35 /55) ，青年占36% ( 20 /55) ，老年人中位
生存期为43mo，青年人中位生存期为35mo，老年人手术方式、术后辅助化疗等因素对病人生存期的影响无统计
学意义( P＞0． 05) 。青年人手术联合化疗相对于其他方式有较长的生存期，有统计学意义( P＜0． 05) 结论: 细支
气管肺泡癌( BAC) 相对于其他非小细胞肺癌亚型有自己的特点，青年BAC 的治疗手术联合化疗优于单一手术
治疗，能提高病人长期生存率。

Objective: To discuss clinical symtoms，diagnosis，path ological type， image characteritics，
treatmentprinciple and prono－sis of bronchioloalveoar cell carcinoma( BAC) between olde man and
young． Mehtod we retrospectively analyzed the clinical data of 55 BAC paitients who were adimitted to
Beijing shijitan hospital from october 2001 to June 2012． Results: The case the ratio of males to famales
was 1． 0: 1． 2，The old man cases in this study are accounted for 64%( 35 /55) ，The young man cases
in this study are accounted for 36% ( 20 /55 ) The median overall survivale was 43． 7months，The
median old man survivale was 43months，The median young survivale was 35months． there was no significant
difference in the old man survival rates of surgery treatment and chemotherapy facters ( P
＞0． 05) effect of surgery and chemotherapy was superior to the surgery treatment of young( P＜0． 05) ．
Conclusion: the incidence of BAC similar between men and women，bronchioloalveoar is not commonly
seen in BAC，effect of surgery and chemotherapy was superior to the surgery treatment of young ( P
＜0． 05) ． surgery and chemotherapy treatment can Improve the patients survival rate．
