A seven-county, predominantly black, rural-poor population in Alabama is targeted for a program aimed at improving access to state-of-the-art cancer care. This paper presents combined age-adjusted cancer incidence rates for predominantly black, rural counties in North Carolina and Georgia similar to the Alabama counties and compares these rates with Surveillance, Epidemiology, and End Results (SEER) incidence rates.
Cancer incidence data from 1990 to 1993 were obtained from the Georgia Center for Cancer Statistics for 10 rural counties with predominantly black populations. Likewise, cancer incidence data from 1990 to 1993 were obtained for seven rural-poor counties in North Carolina from the North Carolina Central Cancer Registry. SEER incidence rates from 1990 to 1992 were obtained for nine SEER sites.
The overall cancer incidence rate from North Carolina and Georgia is lower by 22% than the SEER rate. Cancer incidence rates for cancers of the breast, colon/rectum, lung, and prostate were at least 15% lower than the SEER rates, while the invasive cervical cancer rate was 1.78 times higher than the SEER rate.
Blacks comprise about 50% of the population in these counties. In contrast, the SEER population is predominantly white, and the black population is primarily urban. Estimates of the number of cancer cases in black, rural-poor populations based on SEER incidence rates is not reflective of the cancer experience in these populations.
阿拉巴马州一个以黑人为主的七县农村贫困人口群体成为了一项旨在改善获得先进癌症治疗机会的项目的目标对象。本文呈现了北卡罗来纳州和佐治亚州与阿拉巴马州各县类似的以黑人为主的农村县的综合年龄调整癌症发病率，并将这些发病率与监测、流行病学和最终结果（SEER）发病率进行比较。
1990年至1993年的癌症发病数据分别从佐治亚州癌症统计中心获取了10个以黑人为主的农村县的数据。同样，1990年至1993年北卡罗来纳州7个农村贫困县的癌症发病数据从北卡罗来纳州中央癌症登记处获取。1990年至1992年9个SEER站点的SEER发病率也被获取。
北卡罗来纳州和佐治亚州的总体癌症发病率比SEER发病率低22%。乳腺癌、结肠/直肠癌、肺癌和前列腺癌的发病率比SEER发病率至少低15%，而浸润性宫颈癌发病率比SEER发病率高1.78倍。
这些县中黑人约占人口的50%。相比之下，SEER人群主要是白人，且黑人主要是城市人口。基于SEER发病率对黑人农村贫困人口中癌症病例数的估计并不能反映这些人群的癌症患病情况。
