目的 观察拥有116万人口的启东市1973—2000年宫颈癌发病率。方法根据以人群为基础(population-based)的癌症登记报告制度,采用发病登记报告资料,计算启东市宫颈癌的发病率;采用1964年全国标准人口构成及1960年世界标准人口构成,计算标准化发病率,并观察宫颈癌分布的特点与发病趋势。结果启东市1973～2000年28年的宫颈癌发病登记共631例,占启东市同期女性恶性肿瘤的3.25％(631/19 339),居女性全部恶性肿瘤的第8位。28年中,宫颈癌发病率平均为3.96/10万,中国人口标准化发病率(CASR)为2.67/10万,世界人口标准化发病率(WASR)为3.66/10万。1973～1986年前14年的发病率平均为5.01/10万,1987—2000年后14年的发病率平均为2.97/10万,宫颈癌发病率呈显著的下降趋势,前后14年比较,差异有极显著性(P<0.01)。55岁以上各年龄组宫颈癌发病率下降趋势尤其显著,差异有极显著性(P<0.01)。结论以人群为基础的癌症登记资料表明,启东市的宫颈癌为相对低发区,中老年妇女的发病率呈下降趋势;本资料可为宫颈癌的防治提供基础资料和决策依据。
Objective To observe the incidence of cervical cancer in Qindong City with a population of 1.16 million from 1973 to 2000. Methods According to the population-based cancer registration and reporting system, the incidence of cervical cancer in Qidong was calculated by using the registration report of incidence. Using the national standard population in 1964 and the world standard population in 1960, the standardized incidence was calculated Rate, and observe the distribution of cervical cancer characteristics and incidence trends. Results A total of 631 cervical cancer cases registered in Qidong for 28 years from 1973 to 2000 accounted for 3.25% (631/19 339) of women with malignant tumors in Qidong and 8th of all malignant tumors in women. In 28 years, the average incidence of cervical cancer was 3.96 / 100,000. The CASR was 2.67 / 100,000 and the World Population Standardized Rate (WASR) was 3.66 / 100,000. The average incidence rate of 14 years from 1973 to 1986 was 5.01 / 100000. The incidence of 14 years after 1987-2000 was 2.97 / 100000. The incidence of cervical cancer showed a significant downward trend. The difference between the two groups was 14 years Significantly (P <0.01). The incidence of cervical cancer in all age groups over the age of 55 showed a significant decrease, with significant difference (P <0.01). Conclusions Population-based cancer registration data show that the incidence of cervical cancer is relatively low in Qidong and the incidence of middle-aged and elderly women is on the decline. This data can provide basic information and decision-making basis for the prevention and treatment of cervical cancer.
