Surveillance, Epidemiology, and End Results. It is a premier source for cancer statistics in the United States, managed by the National Cancer Institute. The program systematically collects data on cancer incidence, prevalence, and survival from specific geographic areas representing a significant portion of the U.S. population. Its data is foundational for clinical research, public health policy, and understanding the burden of cancer across diverse communities.

Overview and Purpose

Established in 1973, the program was created to provide reliable, ongoing data for studying cancer trends and outcomes. Its primary purpose is to monitor cancer statistics to reduce the burden of this disease on the population. The information supports the work of agencies like the Centers for Disease Control and Prevention and informs national initiatives such as the Cancer Moonshot. By tracking patterns over time, it helps assess the effectiveness of prevention efforts, including those championed by the American Cancer Society.

Data Collection and Sources

Data originates from a network of high-quality population-based registries covering specific states, counties, and metropolitan areas, such as those in California and Georgia. These registries collect detailed information on patient demographics, tumor characteristics, first course of treatment, and vital status. Sources include hospital records, pathology reports, and vital records from entities like the National Center for Health Statistics. The data is rigorously coded using standards like the International Classification of Diseases for Oncology.

Program Structure and Governance

The program is a core project of the National Cancer Institute's Division of Cancer Control and Population Sciences. Governance and scientific oversight are provided by committees involving experts from institutions like the Mayo Clinic and the Fred Hutchinson Cancer Research Center. Its registry network includes collaborations with state health departments, such as the Louisiana Tumor Registry, and covers specific populations like those in the SEER 18 regions. Funding and direction are tied to the broader mission of the National Institutes of Health.

Key Cancer Statistics and Findings

The program's reports have been instrumental in identifying disparities and trends, such as the rising incidence of melanoma and variations in prostate cancer survival rates. It has documented significant improvements in survival for cancers like Hodgkin lymphoma and testicular cancer since the 1970s. Statistics regularly reveal disparities among racial and ethnic groups, with notable differences in outcomes for breast cancer between Black and White women. Landmark findings have influenced screening guidelines for colorectal cancer nationally.

Research Applications and Impact

Data is extensively used by researchers at institutions like the MD Anderson Cancer Center and the Dana-Farber Cancer Institute for epidemiological studies and clinical trials. It supports investigations into the effectiveness of new treatments approved by the Food and Drug Administration. The statistics are crucial for modeling the future cancer burden, work often conducted in partnership with the American Society of Clinical Oncology. Findings directly inform public health campaigns and resource allocation by state agencies and organizations like the World Health Organization.

Limitations and Challenges

While comprehensive, the data has limitations, including a lag time in reporting that can affect real-time analysis. It does not capture complete treatment histories over a patient's lifetime or detailed information on cancer recurrence. Challenges include maintaining consistent data quality across all registries and adapting to changes in medical coding systems like the International Classification of Diseases. Furthermore, while representative, the coverage areas may not fully capture cancer patterns in all rural regions or among specific groups like Native American populations.
