Abstract

Background

Cancer survival is generally lower in Black persons compared with White persons and in rural areas compared with urban areas. The authors examined variations in age-standardized, stage-specific, 5-year cancer survival and receipt of cancer surgery, chemotherapy, and radiotherapy between Black and White persons in large metropolitan (population ≥1 million), small-medium metropolitan (<1 million), and nonmetropolitan areas.

Methods

Data were obtained for all, lung, female breast, prostate, and colorectal cancers diagnosed in 2015–2021 in individuals aged 15 years and older from the Surveillance, Epidemiology, and End Results 22 registries.

Results

The overall 5-year cancer survival rate for localized-stage, regional-stage, and distant-stage cancers was lower in nonmetropolitan areas than metropolitan areas in both Black and White persons by 2, 5, and 3–7 percentage points and was lower in Black persons compared with White persons across categories of urbanicity by 12, 7, and 4–7 percentage points, respectively. By cancer type, stage-specific survival was lower in Black persons compared with White persons across most categories of urbanicity, especially in large metropolitan areas in those younger than 65 years, for breast and colorectal cancers, and for some stages and categories of urbanicity for lung and prostate cancers. The receipt of cancer surgery for localized-stage and regional-stage cancers were lower in Black persons compared with White persons for most evaluated cancers and categories of urbanicity, whereas the receipt of chemotherapy and radiotherapy varied by cancer, stage, and urbanicity. Lower 5-year cancer survival generally aligned with lower receipt of cancer treatment.

Conclusions

The large differences in stage-specific 5-year cancer survival between rural and urban areas and between Black and White persons likely reflect disparities in the receipt of guideline-concordant care.

2015-2021年,美国按居住县城市化程度划分的黑人和白人癌症分期生存率
背景:黑人的癌症存活率一般低于白人,农村地区的癌症存活率一般低于城市地区。作者检查了大城市(人口≥100万)和中小城市黑人和白人之间年龄标准化、分期特异性、5年癌症生存率和接受癌症手术、化疗和放疗的差异。方法:从监测、流行病学和最终结果22个登记处获得2015-2021年15岁及以上个体诊断的所有肺癌、女性乳腺癌、前列腺癌和结直肠癌的数据。结果:在非大都市地区,黑人和白人的局部期、区域期和远处期癌症的总体5年生存率分别比大都市地区低2、5和3-7个百分点,在不同的城市化类别中,黑人比白人低12、7和4-7个百分点。就癌症类型而言,在大多数城市化类别中,黑人的分期特异性生存率低于白人,尤其是在大城市地区,年龄小于65岁的乳腺癌和结直肠癌患者,以及某些阶段和类别的肺癌和前列腺癌患者。在大多数评估的癌症和城市化类别中,黑人接受局部期和区域期癌症手术的比例低于白人,而化疗和放疗的接受程度因癌症、分期和城市化程度而异。较低的5年癌症生存率通常与较低的癌症治疗接受率一致。结论:农村和城市地区以及黑人和白人之间5年癌症分期生存率的巨大差异可能反映了接受指南一致性治疗的差异。
