Decades of cancer follow-up, waiting for your question.
What it is
A national cancer registry, patient by patient.
SEER (Surveillance, Epidemiology, and End Results) is the US National Cancer Institute's programme of population-based cancer registries. Since 1975 it has recorded every new cancer in its catchment areas, now close to half of the US population, with demographics, primary site and histology, stage at diagnosis, first-course treatment, and vital status updated every year.
What it is built for
Scale, millions of cancer cases, followed for survival since 1975.
Design, survival and competing-risk analysis, conditional survival, treatment effectiveness in trial-excluded groups, nomogram development and validation.
Limits, no recurrence, comorbidity, or systemic-therapy detail; treatment is coded broadly, so questions are designed around that.
How it works
The method, in plain terms.
Define the cohort
ICD-O-3 site, stage, years
Harmonise staging
Across AJCC editions
Describe
Rates, stage, treatment
Survival
Kaplan-Meier, Cox
Competing risks
Fine-Gray models
Model & validate
Nomograms, calibration
How you benefit
Why authors start here.
- Decades of follow-up, ready now. Survival questions that would take a centre twenty years to answer are already recorded.
- Rare cancers become analysable. Population coverage makes uncommon sites and histologies large enough to study.
- Beyond the trial population. Real-world effectiveness in the elderly, in rare stages, and in groups trials exclude.
- You stay the author. We design and run the study with you to ICMJE standards.
Scope the question
We turn your idea into a survival, competing-risk, or prognostic question SEER can actually answer.
Protocol & codes
We pre-specify the cohort, codes, exclusions, outcomes, covariates, and the modelling plan.
Extract & clean
We pull the extract, harmonise staging across editions, and document every exclusion.
Analysis
Survival, competing-risk, and (where planned) nomogram development with validation, in reproducible R code.
Manuscript
We draft a clear paper with you, tables, survival curves, calibration plots, and honest limitations.
Submit & revise
We shortlist the right journals, package the submission, and answer reviewers with you to a decision.
Published examples
