To evaluate whether a country's Human Development Index (HDI) can help explain the differences in the country's breast cancer and gynecological cancer incidence and mortality rates in the Pan-American region.
Ecological analysis.
Pan-American region countries with publicly available data both in GLOBOCAN 2012 and the United Nations Development Report 2012 were included (n = 28). Incidence and mortality rates age-standardized per 100,000 were natural log-transformed for breast cancer, ovarian cancer, corpus uteri cancer, and cervical cancer. The mortality-to-incidence ratio (MIR) was calculated for each site. Pearson's correlation test and a simple linear regression were performed.
The HDI showed a positive correlation with breast cancer and ovarian cancer incidence and mortality rates, respectively, and a negative correlation with cervical cancer incidence and mortality rates. The HDI and corpus uteri cancer showed no association. MIR and the HDI showed a negative correlation for all tumor types except ovarian cancer. An increment in 1 HDI unit leads to changes in cancer rates: in breast cancer incidence β = 4.03 (95% confidence interval [CI] 2.61; 5.45) P < 0.001, breast cancer mortality β = 1.76 (95% CI 0.32; 3.21) P = 0.019, and breast cancer-MIR β = -0.705 (95% CI 0.704; 0.706) P < 0.001; in cervical cancer incidence β = -3.28 (95% CI -4.78; -1.78) P < 0.001, cervical cancer mortality β = -4.63 (95% CI -6.10; -3.17) P < 0.001, and cervical cancer-MIR β = -1.35 (95% CI -1.83; -0.87) P < 0.001; in ovarian cancer incidence β = 3.26 (95% CI 1.78; 4.75) P < 0.001, ovarian cancer mortality β = 1.82 (95% CI 0.44; 3.20) P = 0.012, and ovarian cancer-MIR β = 5.10 (95% CI 3.22; 6.97) P < 0.001; in corpus uteri cancer incidence β = 2.37 (95% CI -0.33; 5.06) P = 0.83, corpus uteri cancer mortality β = 0.68 (95% CI -2.68; 2.82) P = 0.96, and corpus uteri cancer-MIR β = -2.30 (95% CI -3.19; -1.40) P < 0.001.
A country's HDI should be considered to understand disparities in breast cancer and gynecological cancer in the Pan-American region.
评估一个国家的人类发展指数(HDI)是否有助于解释泛美地区乳腺癌和妇科癌症发病率和死亡率的差异。
生态分析。
纳入了在 GLOBOCAN 2012 和联合国发展报告 2012 中均有公开数据的泛美地区国家(n=28)。使用自然对数转换了乳腺癌、卵巢癌、子宫癌和宫颈癌的每 100,000 人标准化发病率和死亡率。计算了每个部位的死亡率与发病率比(MIR)。进行了 Pearson 相关检验和简单线性回归。
HDI 与乳腺癌和卵巢癌的发病率和死亡率呈正相关,与宫颈癌的发病率和死亡率呈负相关。HDI 与子宫癌无关联。除卵巢癌外,MIR 与 HDI 呈负相关。HDI 每增加 1 个单位,癌症发生率就会发生变化:乳腺癌发病率β=4.03(95%置信区间[CI] 2.61;5.45)P<0.001,乳腺癌死亡率β=1.76(95%CI 0.32;3.21)P=0.019,乳腺癌-MIRβ=-0.705(95%CI 0.704;0.706)P<0.001;宫颈癌发病率β=-3.28(95%CI -4.78;-1.78)P<0.001,宫颈癌死亡率β=-4.63(95%CI -6.10;-3.17)P<0.001,宫颈癌-MIRβ=-1.35(95%CI -1.83;-0.87)P<0.001;卵巢癌发病率β=3.26(95%CI 1.78;4.75)P<0.001,卵巢癌死亡率β=1.82(95%CI 0.44;3.20)P=0.012,卵巢癌-MIRβ=5.10(95%CI 3.22;6.97)P<0.001;子宫癌发病率β=2.37(95%CI -0.33;5.06)P=0.83,子宫癌死亡率β=0.68(95%CI -2.68;2.82)P=0.96,子宫癌-MIRβ=-2.30(95%CI -3.19;-1.40)P<0.001。
应考虑一个国家的人类发展指数(HDI),以了解泛美地区乳腺癌和妇科癌症的差异。
