1989-2001年四川省死因监测点恶性肿瘤死亡变化趋势

Epidemic Trend Analysis of Malignant Tumors in Death Cause Surveillance Areas of Sichuan Province From 1989 to 2001

目的掌握四川省死因监测点恶性肿瘤死亡变化趋势。方法应用1989-2001年四川省死因监测资料,对恶性肿瘤死亡及其构成比进行趋势变化分析。结果1989-2001年期间,四川省死因监测地区恶性肿瘤死亡一直位居总死因的第3位,各年度构成比占总死因构成的比例在15%～25%之间,并呈逐年上升趋势;总标化死亡率由1989年的123.4/10万上升到2001年的156.8/10万,平均增长速度1.38%,其中男性(1.68%)高于女性(0.6%),农村(2.02%)高于城市(0.5%);男性和女性、城市和农村的粗死亡率、标化率均呈上升趋势(趋势卡方检验,P<0.01);居前4位的癌种为食管癌、胃癌、肝癌、肺癌,其粗死亡率在13/10万～30/10万之间,并呈上升趋势;膀胱癌、肺癌、肝癌平均增长速度均接近在4%以上;白血病、鼻咽癌和子宫颈癌呈下降趋势。结论四川省监测地区恶性肿瘤死亡水平呈逐年上升趋势,在男性群体和农村地区中更为显著,危害健康的主要癌种呈现多样化、复杂化趋势,主要为食管癌、胃癌、肝癌和肺癌等。

Objective To explore the trend of malignant tumor in death cause surveillance areas of Sichuan Province.Method Epidemic trend of mortality and proportion of malignant tumor were analysed from the data of death cause surveillance areas in Sichuan Province during 1989-2001.Results During 1989-2001,malignant tumor was ranked as the third death cause of all deaths in death cause surveillance areas of Sichuan Province.The malignant tumor proportion in all deaths was between 15%-25% every year and increased year by year.The total standardized mortality of malignant tumor rose from 123.4/105 in 1989 to 156.8/105 in 2001 with a mean increase rapidity of 1.38%.The mena increase repidity of male（1.68%）and of the country（2.02%）showed a higher increase than that of the female（0.6%）and the city（0.5%）.The crude and standardized mortality of malignant tumor in male,female,city and country increased year by year during 1989-2001（trend chi-square test,P〈0.01）.The ratio of mortality of malignant tumor between male and female was at a range of 1.6-2.0,and the ratio between city and country was at 0.9-1.3.The top 4 causes of death in all malignant tumors were oesophagus cancer,stomach cancer,liver cancer,and lung cancer,respectively,and their crude mortality was between 13/105 to 30/105 and increasing year by year.The mean increase rapidity in bladder cancer,lung cancer and liver cancer was above 4%.The crude mortality of leukaemia,nasopharyngeal carcinoma and cervix uteri cancer decreased during 1989-2001.Conclusion The mortality of malignant tumors showed an increasing trend year by year in death cause surveillance areas of Sichuan Province,especially in male and in country.The main malignant tumors were oesophagus cancer,stomach cancer,liver cancer and lung cancer.The malignant tumors showed a diverse and complex trend.Malignant tumor has become a common disease which was severely hazardous to people＇s life and health in death cause surveillance areas of Sichuan Province.
