Two recent studies have found that Medicaid expansion under the ACA improves overall cancer survival among all racial and ethnic groups and reduces racial disparities in cancer survival.

Both articles review previously documented benefits of expanded eligibility, such as fewer patients without insurance coverage, improved racial and ethnic equity in insurance coverage, a shift to less advanced cancer stages at diagnosis, and better adherence to quality-of-care indicators. However, because of the time necessary for registries to collect survival data, very little is known about the impact of Medicaid expansion on survival after a cancer diagnosis.

The first study, which compares the survival rates of patients with de novo stage IV breast cancer 4 years prior to the Medicaid expansion and 3 years afterward, appears in JAMA Oncology (doi:10.1001/jamaoncol.2022.0159). A second new study, appearing in the Journal of the National Cancer Institute (JNCI), compares survival trends for all cancer types, individually and combined, among patients with a cancer diagnosis residing in states that expanded Medicaid access and those residing in states that did not (doi:10.1093/jnci/djac077).

最近的两项研究发现，根据 ACA 扩大医疗补助计划可提高所有种族和族裔群体的整体癌症生存率，并减少癌症生存率方面的种族差异。

这两篇文章都回顾了先前记录的扩大资格的好处，例如减少没有保险的患者，改善保险范围的种族和民族公平，在诊断时转向不太晚期的癌症阶段，以及更好地遵守医疗质量指标。然而，由于登记处收集生存数据所需的时间，人们对医疗补助扩张对癌症诊断后生存的影响知之甚少。

第一项研究比较了 Medicaid 扩张前 4 年和 3 年后新发 IV 期乳腺癌患者的生存率，发表在JAMA Oncology (doi:10.1001/jamaoncol.2022.0159)。发表在《美国国家癌症研究所杂志》 ( JNCI )上的第二项新研究比较了所有癌症类型的生存趋势，这些癌症诊断的患者居住在扩大医疗补助准入的州和居住在扩大医疗补助准入的州的患者中。不是 (doi:10.1093/jnci/djac077)。
