[目的]分析北京市居民癌症流行趋势 ,为肿瘤预防与控制提供科学依据。[方法]利用北京市肿瘤登记组1982年～1997年收集积累的癌症新发病例资料 ,按ICD 9三位数字进行编码。以3年合并资料进行统计分析。用世界标准人口计算标化发病率。对不同时期资料进行比较。[结果]北京市城区恶性肿瘤发病率呈逐年升高的趋势 ,男性标化发病率从162.8/10万上升到176.7/10万 ,女性从130.0/10万上升到140.9/10万 ,15年间上升8.5%。1985年～1997年不同部位肿瘤中 ,男、女性以肺癌居首位(占22.8%) ,其次是胃癌、肝癌、食管癌、结直肠癌 ,各种消化道肿瘤占41.4%。女性中乳腺癌为最多发肿瘤(占18.9%)。15年间肺癌、结直肠癌、胰腺癌呈上升趋势。女性乳腺癌、卵巢癌迅速升高。而胃癌、食管癌呈下降趋势 ,宫颈癌大幅度下降。[结论]北京市近15年癌症发病呈上升趋势 ,提示与经济发展、居民平均寿命延长、人口老龄化密切相关。同时生活方式、饮食结构和生态环境的变化起着重要作用。
[Objective] To analyze the prevalence of cancer in Beijing residents and provide scientific basis for cancer prevention and control. [Methods] The new cancer cases collected and collected by the Beijing Cancer Registry from 1982 to 1997 were coded according to three digits of ICD 9. Statistical analysis was performed using the combined data for three years. Calculate standardized incidence using the world standard population. Compare data from different periods. [Results] The incidence of malignant tumors in urban areas in Beijing showed an upward trend year by year. The standardized rate of males increased from 162.8/100 000 to 176.7/100,000, and that of women rose from 130.0/lakh to 140.9/l.000, which increased during 15 years. 8.5%. From 1985 to 1997, lung cancer was the highest among men and women (22.8%), followed by gastric cancer, liver cancer, esophageal cancer, colorectal cancer, and 41.4% of all kinds of gastrointestinal tumors. Breast cancer is the most common cancer in women (18.9%). In the past 15 years, lung cancer, colorectal cancer and pancreatic cancer have shown an upward trend. Female breast cancer and ovarian cancer increase rapidly. Gastric cancer and esophageal cancer showed a downward trend, and cervical cancer decreased significantly. [Conclusions] The incidence of cancer in Beijing in the past 15 years is on the rise, suggesting that it is closely related to economic development, long life expectancy of residents, and population aging. At the same time, changes in lifestyle, diet structure and ecological environment play an important role.
