根据全国及陕西省恶性肿瘤死亡回顾调查资料:宫颈癌的中国标准人口(1964年全国普查人口)年龄调整死亡率(每10万人口,下略),全国为9.98;陕西省(调整死亡率为16.64)在全国29个省市自治区(台湾资料暂缺)中名列第三;略阳(62.79)、凤县(59.03)及留坝为陕西省宫颈癌的前三位高发县。为了进一步掌握宫颈癌在高发人群中的发病水平和分布规律,探讨其病因及流行因素,并为广泛、深入地开展防治研究工作提供科学依据,从1981年3月至7月对略阳县进行了病因流行病学调查。基本情况略阳县位于陕西省西南部秦岭西段南麓,嘉陵江上游,其西北部与甘肃省相接,东、南部与本省的勉县及宁强县毗邻。该县与成县、徽县、凤县及留坝构成我国陕、甘两省交界处秦岭西段的宫颈癌高发带。该带境内,全为沟壑纵横的多山区。
According to the National and Shaanxi Provincial Cancer Mortality Retrospective Survey, the age-adjusted mortality rate (per 100000 population, slightly less than) of China’s standard population of cervical cancer (national census of 1964) was 9.98 in the whole country; in Shaanxi Province (adjusted mortality rate was 16.64) ranked the third among 29 provinces, autonomous regions and municipalities in Taiwan (data not available in Taiwan); Lueyang (62.79), Fengxian (59.03) and Liuba were the top three high incidence county of cervical cancer in Shaanxi province. In order to further understand the incidence and distribution of cervical cancer in high-risk population, to explore its etiology and epidemic factors, and to provide a scientific basis for extensive and in-depth prevention and treatment work, from March 1981 to July Lueyang County Epidemiological investigation of the cause. Basic situation Lueyang County is located in the southwest of Shaanxi Province, southwest of Shaanxi Province, south of Qinling Mountains, the upper reaches of Jialing River, its northwestern Gansu Province, adjacent to the eastern and southern provinces Mianxian and Ningqiang adjacent. The county and into the county, Huixian County, Feng County and stay dam Shaanxi and Gansu provinces at the junction of the western section of the high incidence of cervical cancer band. The belt, all for the ravine vertical and horizontal mountains.
