Integrated VA Care Linked to Equitable Cancer Survival for Black Veterans

Black veterans receiving cancer care through the Veterans Health Administration (VHA) had overall survival (OS) and cancer-specific survival (CSS) that were comparable to, or slightly better than, those of White or non-Black veterans, according to findings from a systematic review and meta-analysis published in JAMA Network Open.¹ This pattern diverges from disparities long documented in the broader US population, the researchers noted.

What Did the Meta-Analysis Find on Overall and Cancer-Specific Survival?

Researchers pooled data from 603,256 veterans with cancer treated between 1983 and 2017 across 39 studies identified through a PubMed search spanning January 2015 to April 2022; 29 of those studies had sufficient data for meta-analysis. The pooled HR for OS among Black veterans was 0.93 (95% CI, 0.89-0.97), and for CSS, 0.94 (95% CI, 0.90-0.98)—both indicating modestly favorable outcomes relative to White or non-Black veterans. Of 27 articles evaluating OS, 17 (63%) reported similar outcomes by race, 9 reported better outcomes for Black veterans, and 1 reported worse outcomes. Findings for CSS followed a similar pattern across 17 articles.

How Did Outcomes Vary by Cancer Type?

Prostate cancer dominated the evidence base, accounting for 20 of the 29 meta-analyzed studies (69%). Among veterans with prostate cancer, pooled HRs were 0.94 (95% CI, 0.88-0.99) for OS and 0.90 (95% CI, 0.85-0.96) for CSS, favoring Black veterans. Non–small cell lung cancer (NSCLC), evaluated across 4 studies, showed pooled HRs of 0.92 (95% CI, 0.84-1.00) for OS and 0.98 (95% CI, 0.89-1.07) for CSS. Survival advantages for Black veterans were also observed in bladder, laryngeal, oropharyngeal, and plasma cell (myeloma) cancers, while pancreatic, esophageal, and breast cancer studies generally showed no measurable racial differences. Between-study heterogeneity was characterized as low to moderate, and funnel plots suggested minimal publication bias.

What Did a Direct Comparison With the General US Population Show?

One study included in the review compared VHA outcomes directly against the broader US population.² The analysis, which drew on 4,485,170 veterans with cancer (718,720 of whom were Black [16.0%]), compared OS and CSS between VHA patients and the general population stratified by race and ethnicity using National Center for Health Statistics mortality files. The study found fewer racial and ethnic disparities within the VHA than in the general population, though the authors noted that equal-access health care may only partially explain the pattern, with other nonhealth care factors also likely contributing.

What Explains the Survival Parity Seen in VHA Care?

The authors point to the VHA's structure as a likely driver: the system offers standardized, near-equal access to care without insurance premiums and with minimal copayments, alongside colocated primary, specialty, and diagnostic services and ancillary supports such as transportation and housing assistance.¹ This contrasts with the broader US population, where disparities in cancer survival by race persist even after adjustment for age, sex, and disease stage, and where lower socioeconomic status, unequal access to care, and higher exposure to environmental and occupational carcinogens have been implicated as contributing factors. The authors concluded that integrated health systems providing more equitable access to comprehensive cancer care may substantially reduce or eliminate the outcome disparities seen elsewhere.

The Study Limitations

The authors cautioned that the evidence base is heavily weighted toward prostate cancer, limiting generalizability to other tumor types, including colorectal and pancreatic cancers, which were underrepresented or absent. They also raised the possibility of a "healthy Black veteran effect," in which veterans who sustain long-term VHA engagement may be positively selected with respect to health or resilience, as well as potential collider bias from unmeasured factors influencing cohort inclusion. Geographic clustering of Black veterans in the Southern US, and the concentration of their care within a limited number of VHA medical centers, may further limit how broadly the findings apply.
