Our study compared cancer incidence rates and stage distribution between non-Hispanic Whites and Hispanic Whites in the United States between 1992 and 2009.
A retrospective cohort study was conducted for the years 1992 through 2009.
Data represent 13 registries in the Surveillance, Epidemiology, and End Results Program, which reflect 14% of the total US population.
The incidence rates for most cancer sites were significantly higher in non-Hispanic Whites than in Hispanic Whites. Exceptions included cancers of the stomach and liver and, for females only, kidney and renal pelvis and cervix uteri. Overall, cancer incidence in non-Hispanic Whites was 40% greater in males and 34% greater in females as compared with Hispanic Whites. Cancer sites with higher incidence rates among non-Hispanic Whites than Hispanic Whites in 2009 compared with 1992 were melanoma, thyroid cancer, oral cavity and pharynx cancer, lymphoma, urinary bladder cancer, and all cancers combined for males and melanoma, thyroid cancer, cervical cancer, and lung and bronchus cancer for females. However, difference in rates narrowed between the ethnicities for colon and rectal cancer and corpus and uterus cancer. Non-Hispanic Whites tended to have a higher percentage of early staged cancer, with little evidence that disparity between the ethnic groups was narrowing in terms of early detection. However, two exceptions involved liver cancer and thyroid cancer in females. The disparity appeared to widen for lung cancer in males.
Cancer incidence rates are generally lower in Hispanic Whites than non-Hispanic Whites. The difference in rates between groups has widened over the study period for many cancer sites, with a few exceptions. Poorer screening practices among Hispanic Whites have tended to persist.
本研究比较了 1992 年至 2009 年间美国非西班牙裔白人和西班牙裔白人的癌症发病率和分期分布。
对 1992 年至 2009 年进行回顾性队列研究。
数据代表监测、流行病学和最终结果计划中的 13 个登记处，反映了美国总人口的 14%。
大多数癌症部位的发病率在非西班牙裔白人中明显高于西班牙裔白人。例外情况包括胃癌和肝癌，以及仅女性的肾癌和肾盂癌和宫颈癌。总体而言，与西班牙裔白人相比，非西班牙裔白人男性的癌症发病率高 40%，女性高 34%。2009 年与 1992 年相比，非西班牙裔白人发病率高于西班牙裔白人的癌症部位包括黑色素瘤、甲状腺癌、口腔和咽癌、淋巴瘤、膀胱癌和所有癌症的男性以及黑色素瘤、甲状腺癌、宫颈癌和肺癌男性和支气管癌。然而，结肠癌和直肠癌以及子宫体癌和子宫颈癌的种族之间的发病率差异缩小。非西班牙裔白人倾向于有更高比例的早期分期癌症，几乎没有证据表明种族群体之间在早期发现方面的差距正在缩小。然而，有两个例外涉及女性的肝癌和甲状腺癌。男性肺癌的差异似乎在扩大。
癌症发病率在西班牙裔白人中普遍低于非西班牙裔白人。在许多癌症部位，种族之间的发病率差异在研究期间有所扩大，但也有一些例外。西班牙裔白人的筛查实践较差，这一现象一直持续存在。
