1981～2000年梧州市肺癌发病情况及趋势分析

Analysis of lung cancer incidence in Wuzhou city from 1981 to 2000

目的 了解梧州市肺癌发病情况及趋势 ,为梧州市肺癌防治提供科学依据。方法 利用梧州市1981～ 2 0 0 0年恶性肿瘤登记报告资料 ,对肺癌进行发病率统计分析 ,计算各年龄段、各时期发病率 ,并对各时期发病率进行比较。以世界标准人口计算标化发病率、截缩率。结果 梧州市肺癌发病率高 ,其发病占全癌发病总数的 2 1.65 %。 2 0年间 ,梧州市肺癌发病率呈显著性上升趋势 (P <0 .0 0 1) ,男性由 2 5 .33× 10 -5,上升至 47.73× 10 -5,升高了 88.43% ;女性由 10 .12× 10 -5,上升至 2 4.66× 10 -5,升高了 12 1.2 2 %。调整年龄后 ,标化发病率也同样呈上升趋势。发病的中位年龄男性为 64 .5岁 ,女性为 65 .6岁 ,多发于 5 5岁以上的人群 ,5 5岁以上发病占 88.8%。结论 梧州市肺癌不但发病率高 ,而且发病趋势上升十分显著 ,是梧州市恶性肿瘤防治研究的重点之一。

Objective To investigate the incidence of lung cancer and the trend of the incidence in Wuzhou. Methods Based on the lung cancer patients’ data collected in Wuzhou from 1981 to 2000, statistical analysis of the lung cancer incidence rates was performed, the lung cancer incidence rates for age groups and for periods of time were calculated, and the incidence rates for different periods were compared. Using standard world populations the standardized incidence rates of lung cancer and the intercept standardized rate were also calculated. Results The lung cancer incidence rate was high in Wuzhou. The lung cancer accounted for 21.65% (1 264/5 838) of all cancers. From 1981 to 2000, the incidence rate of lung cancer in Wuzhou increased markedly (P<0.001); the incidence rate for males increased by 88.43% from 25.33×10 -5 to 47.37×10 -5 ; the rate for females rose by 121.22% from 10.12×10 -5 to 24.66×10 -5 . So was the standardized incidence rate. The median age for the male was 64.5 years old, while the median age for the female was 65.6. 88.8% of the patients were in the age of 55 year old or more. Conclusion The lung cancer incidence rate in Wuzhou is high, and the incidence is significantly increased. Therefore, preventing lung cancer is one of the main cancer prevention tasks in Wuzhou.
