Cervical cancer mortality trends in Piauí, 2000-2011

Abstract Introduction To evaluate cervical cancer mortality trends in Piauí and 11 its development territories (DT) for the period 2000-2011. Methods We conducted time series analysis with deaths data obtained from the National Mortality Database, and population data from the Brazilian Institute of Geography and Statistics. Mortality rates were corrected on the basis of proportional redistribution of the deaths from “cervical cancer, part unspecified” and standardized for age. Time trends were evaluated by Joinpoint method. Results There was an increase in cervical cancer mortality trends for the State as the whole (APC=+2.3; CI95%=0.2-4.5). In the period, it was observed upward trends in mortality rates DT 5 (APC=+11.6; CI95%=9.4-37.5), and DT 10 (APC=+11.4; CI95%=0.7-23.2). Other DTs presented stable trends. Conclusions In the period 2000-2011, there was upward trend of cervical cancer mortality rates, suggesting difficulty of early diagnosis and treatment of this neoplasm in the State.

【摘要】为评估2000-2011年皮奥伊州（Piauí）及其下辖11个发展辖区（Development Territories，DT）的宫颈癌死亡率变化趋势。方法 本研究采用时间序列分析法，死亡数据取自国家死亡数据库（National Mortality Database），人口数据来源于巴西地理与统计研究所（Brazilian Institute of Geography and Statistics）。研究针对部位未特指的宫颈癌死亡病例开展比例重分配以校正死亡率，并按年龄进行标化；采用连接点回归法（Joinpoint）分析时间变化趋势。结果 全皮奥伊州的宫颈癌死亡率整体呈上升趋势（年度百分比变化（Annual Percent Change，APC）=+2.3；95%置信区间（95% Confidence Interval，CI95%）=0.2~4.5）。研究期内，发展辖区5（DT5）的死亡率呈显著上升趋势（APC=+11.6；95%CI=9.4~37.5），发展辖区10（DT10）的死亡率亦呈上升趋势（APC=+11.4；95%CI=0.7~23.2）；其余发展辖区的死亡率趋势较为平稳。结论 2000-2011年期间，皮奥伊州的宫颈癌死亡率呈上升趋势，提示该州在该恶性肿瘤的早期诊断与治疗方面存在困难。
