Abstract

Background

Asian Americans have the highest ovarian cancer survival across the major racial groups although it is unclear whether this survival advantage is observed when each Asian ethnic subgroup is examined separately. Disaggregated survival analyses of this heterogeneous population is needed to ensure ethnic-specific disparities are not overlooked.

Methods

Data on ovarian cancer cases diagnosed from 2006 through 2020 from the Surveillance, Epidemiology, and End Results (SEER) Program were analyzed. Age-standardized five-year cause-specific survival was calculated for Non-Hispanic Whites and seven Asian ethnic subgroups in the U.S. (Asian Indian/Pakistani, Chinese, Filipino, Hawaiian/Pacific Islander, Japanese, Korean, Vietnamese) by stage and histotype. Multivariable Cox regression analyses using a weighted approach were conducted to calculate average hazard ratios (AHRs) and 95 % confidence intervals (CIs) to quantify the risk of ovarian cancer death comparing each Asian ethnic subgroup to Non-Hispanic Whites.

Results

Hawaiian/Pacific Islanders were the only Asian subgroup to show lower five-year cause-specific survival than Non-Hispanic Whites (44.99 % versus 47.90 %, respectively); Asian Indian/Pakistanis showed the highest survival (56.12 %). After adjusting for sociodemographic, tumor, and treatment characteristics, Asian Indian/Pakistani ovarian cancer patients were 17 % less likely to die from their disease whereas Hawaiian/Pacific Islander patients were 28 % more likely to die when compared to Non-Hispanic Whites (AHR = 0.83, 95 % CI 0.75–0.92 and AHR = 1.28, 95 % CI 1.07–1.53, respectively).

Conclusions

There are clear ethnic-specific survival disparities among Asian American ovarian cancer patients that are missed when the population is examined as a single group, further highlighting the need for data disaggregation in future ovarian cancer research.

2006-2020 年亚裔美国人卵巢癌存活率的差异。
背景:在各主要种族群体中,亚裔美国人的卵巢癌存活率最高,但目前还不清楚在对每个亚裔亚群进行单独研究时是否能观察到这种存活优势。有必要对这一异质性人群进行分类生存分析,以确保种族特异性差异不被忽视:方法:分析了来自监测、流行病学和最终结果(SEER)计划的 2006 年至 2020 年卵巢癌诊断病例数据。按分期和组织类型计算了美国非西班牙裔白人和七个亚裔亚群(亚裔印度/巴基斯坦人、华人、菲律宾人、夏威夷/太平洋岛民、日本人、韩国人和越南人)的年龄标准化五年特定病因生存率。采用加权法进行多变量考克斯回归分析,计算平均危险比(AHRs)和95%置信区间(CIs),以量化每个亚裔亚群与非西班牙裔白人相比的卵巢癌死亡风险:夏威夷/太平洋岛民是唯一一个五年特定病因生存率低于非西班牙裔白人的亚裔亚群(分别为44.99%和47.90%);亚裔印度/巴基斯坦人的生存率最高(56.12%)。在对社会人口学、肿瘤和治疗特征进行调整后,与非西班牙裔白人相比,亚裔印第安人/巴基斯坦人卵巢癌患者因病死亡的可能性降低了17%,而夏威夷人/太平洋岛民患者因病死亡的可能性增加了28%(AHR = 0.83,95 % CI 0.75-0.92 和 AHR = 1.28,95 % CI 1.07-1.53):结论:亚裔美国人卵巢癌患者中存在明显的种族特异性生存差异,如果将亚裔美国人作为一个单一群体进行研究,则会忽略这些差异,这进一步强调了在未来的卵巢癌研究中进行数据分类的必要性。
