UNASSIGNED: In this retrospective, population-based longitudinal cohort study, we identified patients diagnosed with first primary prostate cancer between 1995 and 2019, with follow-up until Dec 31, 2019, using population-based cancer registries\' data from the Surveillance, Epidemiology, and End Results (SEER) Program. We calculated the cumulative incidence of death for each racial/ethnic group (Black, white, Hispanic, Asian or Pacific Islander [API], and American Indian or Alaska Native [AI/AN] people), by diagnostic period and cause of death. We quantified absolute disparities using rate changes for the 5-year cumulative incidence of death between racial/ethnic groups and diagnostic periods. We estimated relative (Hazard ratios [HR]) racial/ethnic disparities and the percentage of potential factors contributed to racial/ethnic disparities using Cox regression models.
UNASSIGNED: Despite a decreasing trend in the cumulative risk of death across five racial/ethnic groups, AI/AN and Black patients consistently had the highest rate of death between 1995 and 2019 with an adjusted HR of 1.48 (1.40-1.58) and 1.40 (1.38-1.42) respectively. The disparities in all-cause mortality between AI/AN and white patients increased over time, with adjusted HR 1.32 (1.17-1.49) in 1995-1999 and 1.95 (1.53-2.49) in 2015-2019. Adjustment of stage at diagnosis, initial treatment, tumor grade, and household income explained 33% and 24% of the AI/AN-white and Black-white disparities in all-cause death among patients with prostate cancer.
UNASSIGNED: The enduring racial/ethnic disparities in patients with prostate cancer, call for new interventions to eliminate health disparities. Our study provides important evidence and ways to address racial/ethnic inequality.

■在这次回顾中,基于人群的纵向队列研究,我们确定了1995年至2019年间诊断为第一原发性前列腺癌的患者,随访至2019年12月31日,使用来自监测的基于人群的癌症登记数据,流行病学,和最终结果(SEER)计划。我们计算了每个种族/族裔群体的累计死亡发生率(黑人,白色,西班牙裔,亚洲或太平洋岛民[API],和美洲印第安人或阿拉斯加原住民[AI/AN]人),诊断期和死因。我们使用种族/族裔群体和诊断期之间5年累计死亡发生率的比率变化来量化绝对差异。我们使用Cox回归模型估计了相对(危害比[HR])种族/族裔差异以及导致种族/族裔差异的潜在因素百分比。
■尽管五个种族/民族的累计死亡风险呈下降趋势,AI/AN和Black患者在1995年至2019年期间的死亡率始终最高,调整后的HR分别为1.48(1.40-1.58)和1.40(1.38-1.42)。AI/AN和白人患者之间的全因死亡率差异随着时间的推移而增加,1995-1999年调整后HR1.32(1.17-1.49),2015-2019年调整后HR1.95(1.53-2.49)。诊断阶段的调整,初始治疗,肿瘤分级,和家庭收入解释了33%和24%的AI/AN-白色和黑白差异前列腺癌患者的全因死亡。
■前列腺癌患者中持久的种族/民族差异,呼吁采取新的干预措施来消除健康差距。我们的研究提供了解决种族/民族不平等的重要证据和方法。
