摘　　要：目的了解常熟市居民的肺癌生存情况,科学合理地评价常熟市近年来肺癌防治措施的效果。方法对常熟市2008-2010年确诊登记的732例肺癌新发病例的生存情况进行分析,采用Kaplan-Meier法计算中位生存时间和平均生存时间,用对数秩检验（log-rank test）检验它们的差别;采用寿命表法计算观察生存率,EdererⅡ法计算相对生存率。结果常熟市2008-2010年肺癌患者3年观察生存率为39.89%,相对生存率为43.78%。经对数秩检验（log-rank test）,男女性肺癌患者生存时间差别无统计学意义（χ2=3.13,P〉0.05）,不同年龄组肺癌患者生存时间差别有统计学意义（χ2=9.88,P〈0.05）。80~岁年龄组肺癌患者1~3年观察生存率均低于其他各年龄组。结论应进一步采取更具针对性的防治措施,延长肺癌患者的生存时间。Objective To understand the survival state in lung cancer patients in Changshu city and to scientifically evaluate the effect of lung cancer prevention and treatment in recent years. Methods During2008- 2010,732 new diagnosed lung cancer cases were analyzed. The mean and median survival time were calculated by Kaplan- Meier method, and were tested by log- rank test. Observed survival rate was calculated by life table method and relative survival rate was calculated by EdererⅡ method. Results The3- year observed survival rate and relative survival rate of lung cancer cases during 2008- 2010 in Changshu was 39. 89 % and 43. 78 %,respectively. In terms of survival time,the difference was not statistical significance on gender（ χ2= 3. 13, P〈0. 05）, while showed statistical significance in different age groups（ χ2= 9. 88,P〉0. 05）. The 1- 3 year observed survival rates of cases in 80- age group were lower than that of other age groups. Conclusion More targeted preventive and treatment measures should be taken to prolong the survival time of lung cancer patients.
