Studies have shown increased prevalence rates for breast cancer, relating to higher incidence, longer survival and breast cancer prevention programs among populations. The aim here was to analyze the annual prevalence of breast cancer in Goiânia over a 15-year period.
This was a cross-sectional study on women with breast cancer diagnosed in Goiânia, Goiás, Brazil, from 1988 to 2002.
The breast cancer cases were identified in the database of the Population-Based Cancer Registry of Goiânia. The 15-year period was stratified into three five-year periods. The cases were followed up for five years, and the mortality database was used to exclude deaths. The population of the official census was used as the denominator for rate calculations.
The coefficient of breast cancer prevalence in Goiania was 22.87/100,000 in 1988 and 220.22/100,000 women in 2002. The analyses for periods showed that in the first period, the rate was 19.39/100,000 and that it was 44.79/100,000 in the last period. For the fifteen years analyzed, the prevalence rate for breast cancer was 127.24/100,000 women. The annual percentage change was 27.07 (P < 0.001; 95% confidence interval, CI: 20.79-33.67) from 1988 to 1992 and 9.39 (P < 0.001; 95% CI: 8.52-10.25) from 1992 to 2002.
There was an increase in the breast cancer prevalence rate in the city of Goiânia between 1988 and 2002, possibly relating to the improvement in the screening and treatment of breast cancer.
研究表明，乳腺癌的患病率有所上升，这与人群中发病率升高、生存期延长以及乳腺癌预防项目有关。本研究旨在分析戈亚尼亚市15年间乳腺癌的年患病率。
这是一项对1988年至2002年在巴西戈亚斯州戈亚尼亚市诊断出的乳腺癌女性患者进行的横断面研究。
在戈亚尼亚市基于人群的癌症登记数据库中识别乳腺癌病例。15年期间被分为三个五年期。对病例进行了五年随访，并使用死亡率数据库排除死亡病例。官方人口普查的人口用作计算发病率的分母。
1988年戈亚尼亚市乳腺癌患病率系数为22.87/10万，2002年为220.22/10万女性。各时期分析显示，第一个时期发病率为19.39/10万，最后一个时期为44.79/10万。在分析的15年中，乳腺癌患病率为127.24/10万女性。1988年至1992年的年变化百分比为27.07（P<0.001；95%置信区间，CI：20.79 - 33.67），1992年至2002年为9.39（P<0.001；95%CI：8.52 - 10.25）。
1988年至2002年期间，戈亚尼亚市乳腺癌患病率有所上升，这可能与乳腺癌筛查和治疗的改善有关。
