Five-year survival for children and adolescents diagnosed with cancer in the United States climbed to nearly 90% by 2017, up from 60% in 1975, though persistent racial and ethnic disparities remain across multiple malignancies.
Survival Rates Improve but Disparities and Late Effects Remain
- Survival Progress: Nearly 9 out of 10 young patients now live at least five years past their diagnosis, a major leap from roughly 6 out of 10 in 1975.
- Disparities: Non-Hispanic Black patients continue to experience lower overall survival rates compared to non-Hispanic white and Hispanic peers.
- Lifelong Care: Successful treatment requires long-term medical monitoring, as late effects can emerge decades later.
Registry Analysis Tracks Decades of Survival Gains
The overall survival improvements for pediatric and adolescent patients were detailed in a registry analysis published in the Journal of the National Cancer Institute. Investigators drew on the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) 8 and SEER 17 registries. These databases captured patients diagnosed with cancer at ages 0 to 19 years between 1975 and 2022. The SEER 8 cohort included 52,165 patients, and the SEER 17 cohort included 100,110.
In 1975, about six out of ten patients were alive five years after diagnosis, a figure that reached nearly 90% by 2017, UA.News reported. Pediatric oncologist Lindsay Schwartz of Ann & Robert H. Lurie Children’s Hospital of Chicago noted the clinical drivers behind this trajectory.
“More accurate diagnostics, risk stratification, clinical trials, molecularly targeted drugs and immunotherapy may have contributed to the progress,” Schwartz told News-Medical. At the same time, she said that some patients still need more effective and less toxic treatments.
Persistent Racial Gaps Across Multiple Cancers
Despite overall gains, investigators found that improvements have been uneven across cancer types and racial and ethnic groups. Non-Hispanic Black patients had the lowest 5-year overall survival across multiple cancers, a gap that held after adjustment for age and decade of diagnosis. “Understanding drivers of disparities is essential to achieve equitable outcomes for all young cancer patients,” the study authors wrote.
Data from the study show that during the 2000–2017 period, five-year survival across all cancer types combined was 88% among non-Hispanic white patients, 84.5% among Hispanic patients, 85.6% among patients from other racial and ethnic groups, and 80.8% among non-Hispanic Black patients, UA.News reported. Worse outcomes for Black children and adolescents were recorded for most cancer types.
| Patient Population (2000–2017) | Combined 5-Year Survival Rate |
|---|---|
| Non-Hispanic White Patients | 88.0% |
| Patients from Other Racial/Ethnic Groups | 85.6% |
| Hispanic Patients | 84.5% |
| Non-Hispanic Black Patients | 80.8% |
Survival Rates Vary by Specific Cancer Type
Progress varied significantly depending on the specific malignancy. Five-year survival for acute lymphoblastic leukemia, the most common childhood cancer, rose from 43% in 1975 to 95% in 2017, UA.News reported. Survival reached about 72% for acute myeloid leukemia and about 74% for sarcomas.
The research also emphasized the necessity of lifelong medical monitoring for childhood cancer survivors. Among patients treated for Hodgkin lymphoma in the 1970s and early 1980s, survival declined from 87% five years after diagnosis to 63% after 30 years, highlighting long-term treatment-related toxicities and secondary health risks that require ongoing clinical surveillance.
Contraindications & When to Consult a Doctor
Childhood cancer survivors and their families must maintain regular follow-up care with oncology specialists to monitor for late-onset cardiotoxicity, secondary malignancies, and endocrine dysfunction associated with historical therapies. Patients presenting with persistent fatigue, unexplained localized pain, recurrent fevers, or neurological changes require immediate clinical evaluation by a qualified physician.
Five-year overall survival for children and adolescents diagnosed with cancer in the United States improved from 60% in 1975 to 90% in 2017, according to registry data published in the Journal of the National Cancer Institute.
