A new American Cancer Society study reveals that immune checkpoint inhibitors, while improving survival across all insurance groups, have widened survival disparities between uninsured patients and those with private insurance for advanced melanoma, lung, and kidney cancers.
Two-year survival rates for stage IV melanoma patients increased from 16.2% to 28.3% among uninsured individuals compared to 28.7% to 46.0% among privately insured patients, creating a 6.1 percentage point disparity gap.
The study analyzed 183,440 patients diagnosed between 2002-2019 and found that Medicaid patients showed similar survival improvements to privately insured patients, suggesting Medicaid expansion could help bridge access gaps.
Researchers emphasize the urgent need for health policies expanding insurance coverage and making costly immunotherapies more affordable as these treatments become standard care for early and late-stage cancers.
