不同年龄肺癌患者发病及病理类型临床分析

Clinical analysis on pathological types and incidences of lung cancer patients

目的 研究2002至2008年我院收治的各年龄段肺癌患者的发病及病理类型情况.方法 采用前3年（2002年9月至2005年8月）和后3年（2005年9月至2008年9月）两个时间段作对比,并将患者分为20～35、36～50、51～65、66～80岁年龄段,对其性别、吸烟情况及肺癌病理类型,进行统计学分析比较.结果 前3年性别比为1.59：1;后3年性别比为1.35：1,两者差异有统计学意义（P＜0.05）,男、女肺癌高发年龄段均在51～65岁.前3年吸烟有144例（占59.02%）,其中男94例（占38.52%）,女50例（占20.49%）;后3年吸烟有138例（占56.56%）,其中男92例（占37.70%）,女46例（占18.85%）,大部分患者有吸烟史.前3年51～65岁年龄段鳞癌占首位,为48例（占19.67%）,其次为小细胞癌32例（占13.11%）;后3年51～65岁年龄段鳞癌亦占首位,为54例（占22.13%）,其次为腺癌28例（占11.48%）.结论 前、后3年肺癌的病理类型以鳞癌占多数,多在51～65岁年龄段发生,考虑原因主要是与吸烟关系密切.

Objective To study the incidence of lung cancer in different ages patients and the pathological types in our hospital from 2002 to 2008. Methods All 488 patients were divided into two sections, the first 3 years group （from September 2002 to August 2005） and the following 3 years group （from September 2005 to September 2008）. Meanwhile the patients were also divided into 4 groups according to age：20 ～ 35 years old, 36 ～50 years old, 51 ～ 65 years old and 66 ～ 80 years old. The gender, smoking history and lung cancer pathologic type were statistically analyzed and compared. Results The sex ratio was 1.59：1 in the first 3 years group, and 1.35：1 in the following 3 years group. The difference was significantly different（P 〈0.05）. There were 144 patients in the first 3 years and 138 cases in the following 3 years who had smoking history. Conclusions Before and after three years of lung cancer pathological type to the majority, squamous cell carcinoma in 51 ～65 years of age, consider main reason is closely associated with smoking. Stop smoking is an effective way to prevent lung cancer.
