2004年-2013年肺癌病例特征分析

目的 了解并分析本地区肺癌患者的流行病学特征。方法 收集2004 年-2013 年在某院初次就诊的肺癌病例的临床资料，对其流行病学特征进行描述，并分析前后五年肺癌发病特征及变化。结果 2004 年-2013 年初次住院的肺癌患者有3399 例，肺癌高发年龄段均为61 岁-70 岁，男性肺癌患者是女性的1.99 倍；有47.10%的病例来源于本市户籍居民；病理类型以腺癌为主，占44.21%。经检验前后五年的肺癌发病的年龄差异无统计学意义（t =-0.77，P =0.44），性别分布差异无统计学意义（χ^2=0.84，P =0.36），病理类型差异有统计学意义（χ^2=56.60，P =0.00）。结论 肺癌住院病例呈逐年递增趋势，发病年龄主要集中在61 岁-70 岁，男性居多，近五年腺癌比例有上升趋势。

Analysis of Cases Characteristics of Lung Cancer from 2004 to 2013

Objective To study the epidemiological characteristics of local lung cancer patients. Methods The clinical materials of lung cancer patients admitted in our hospital from 2004 to 2014 were collected. Those characteristics and dynamic changes were described and analyzed. Results There were 3399 first hospitalized lung cancer patients in our hospital from 2004 to 2013. Lung cancer incidence age was 61to70 years old, male patients with lung cancer is 1.99 times more than that of women. There were 47.10% of the cases from this city residents. The major pathologic type was adenocarcinoma, which accounted 44.21%. There was no statistical significance difference in age （t=-0.77, P=0.44） and gender distribution（ X^2=0.84, P=0.36）,meanwhile the difference was statistically significant in constitute of pathological types（ X^=56.60, P=0.00）. Conclusion Lung cancer cases are increasing year by year, and mainly concentrated in the age of 61 to 70 years old. Those cases most were male and the proportion adenocarcinoma has risen nearly five years.
