Blood Cancer Treatment Advances Have Saved Nearly 26 Million Years of Life Over 75 Years
核心洞察
A new "life-years saved" methodology quantifies that blood cancer treatment advances saved an estimated 25.8 million life-years in the U.S. from 1949 through 2024.
Blood cancers account for nearly 10% of all U.S. cancer diagnoses, with more than 192,000 new cases expected this year, and progress depends almost entirely on therapeutic innovation.
On the current trajectory, blood cancer therapies are projected to add 18.9 million life-years from 2026 to 2040, with up to 1 million additional life-years possible through accelerated innovation and expanded access.
A new analysis published in Blood Advances introduces a novel "life-years saved" methodology that, for the first time, quantifies the impact of blood cancer treatment advances over the past 75 years, beginning when the first chemotherapies emerged. The research, led by Blood Cancer United (搜索), is a retrospective analysis examining progress from 1949 through 2024, and found that advances in therapies for leukemia (搜索), lymphoma (搜索), myeloma (搜索) and other blood cancers have resulted in an estimated 25.8 million life-years saved in the United States.
The methodology translates decades of scientific progress into a universally meaningful measure: more time. Using data from the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) Program, and integrating cancer incidence, mortality and U.S. life expectancy, the life-years saved methodology calculates the amount of life restored because of therapeutic innovation.
A New Way to Measure Progress
Blood cancers account for nearly 10% of all cancer diagnoses in the United States, and incidence has continued to rise over time, with more than 192,000 new cases expected this year. Unlike many solid tumor cancers where prevention and screening drive improved survival, progress against blood cancers depends almost entirely on therapeutic innovation and access to treatment.
"As blood cancer incidence continues to rise and more patients depend on ongoing or lifelong treatment for survival, traditional measures such as five-year survival rates and mortality rates do not capture the full story of progress against blood cancer," said E. Anders Kolb, M.D., president and CEO at Blood Cancer United (搜索). "Life-years saved – the number of additional years of life gained because of treatment advances – provides a more meaningful way to monitor progress over time and assess how changes in healthcare policy, research funding and access to treatment may impact patients' lives."
Life-years saved gives researchers, advocates and policymakers a new way to measure whether scientific advances and access to care are translating into more time for blood cancer patients. This comes at a critical time as remarkable scientific advances over the past few decades have led to life-saving therapies, but continued progress depends on sustained research funding, faster development of promising treatments, clinical trial participation, improving access to care, and healthcare policies that help patients navigate and afford care.
Key Findings and Future Projections
Researchers estimate that blood cancer treatments have saved 25.8 million life-years from 1949 through 2024. On the current trajectory, blood cancer therapies are expected to add 18.9 million life-years from 2026 to 2040, but that projection is not a target or guarantee. Health policy changes that limit coverage, create barriers to care, or limit access to effective treatments could significantly slow progress.
Accelerating scientific innovation and expanding access to care could accelerate the trajectory by 1 million additional life-years by 2040 (with an estimated range of 0.8 million to 1.5 million) beyond what would otherwise be achieved. This is the opportunity Blood Cancer United (搜索) is working to realize through its Bold Goal.
Early gains in life-years saved were driven by cytotoxic therapy, radiation and transplantation. Progress accelerated with the introduction of monoclonal antibodies, kinase inhibitors, and other targeted therapies. Future progress will rely on innovative combinations, precision medicines and next-generation immunotherapies, including bispecific antibodies, antibody-drug conjugates, and cellular therapies.
Progress Varies by Cancer Type
Substantial improvement in Hodgkin lymphoma (搜索) and acute lymphoblastic leukemia (搜索) treatment began decades ago, leading to the largest cumulative life-years saved to this point. About 32% of the total life-years saved is for Hodgkin lymphoma and 25% for acute lymphoblastic leukemia. Non-Hodgkin lymphoma (搜索) accounts for about 21% of all life-years saved, driven by more recent advances in immunotherapies such as rituximab (approved in 1997) and the large incidence of non-Hodgkin lymphoma.
Acute myeloid leukemia (搜索) shows the smallest gains, especially among older adults, pointing to the need for new first-in-class therapies.
Persistent Racial Disparities
The analysis also highlights significant gaps across diseases and racial groups. Black patients experience significantly worse survival than White patients across most blood cancers. Multiple myeloma (搜索) is a notable exception, with equitable or better outcomes for Black patients when access to treatment is comparable.
"This new methodology gives us a clear, intuitive way to measure progress, and to see where we must accelerate it," said co-author Ann-Kathrin Eisfeld, M.D., a hematologic oncologist at The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James). "While millions of life-years have been gained, the data show stark gaps, particularly for Black patients and those with acute myeloid leukemia (搜索). Continued investment in research and equitable access to advanced therapies are essential to ensuring all patients benefit from scientific progress. Now we will be able to track progress, or the lack thereof, moving forward, to be able to provide feedback for critical need areas—and required investments."
The Path Forward
According to the authors, increasing life-years saved will require sustained research investment across federal, nonprofit and industry sectors; broader access to advanced therapies and effective treatments; faster development of first-in-class drugs, especially for acute myeloid leukemia (搜索) and other myeloid cancers; and targeted efforts to close racial and age-based survival disparities.
These priorities align with Blood Cancer United (搜索)'s Bold Goal to enable people with blood cancer to gain more than 1 million years of life by 2040, beyond what would otherwise be achieved. Reaching that goal will require continued investment in research, faster therapeutic innovation and broader, more equitable access to effective treatments. Blood Cancer United plans to develop an annual report to measure progress across blood cancers and toward its Bold Goal.
"The past 75 years prove that when we invest in scientific discovery, we give patients more time," said Dr. Kolb. "Every year of life matters, and millions more are within reach if we sustain research funding, accelerate the next generation of breakthroughs and ensure better access to treatment for everyone."
