The SEER program provides active follow-up on all living patients of cancer except those with in situ cancer of the cervix uteri. This method requires a great deal of resources.
Many Cancer Registries do not have sufficient resources to conduct active follow-up on patients. The aim of this study is to see whether the passive method of follow-up yields similar and reliable results to those using more resource-intensive methods.
A survival analysis is an ideal tool to measure this, since it depends on current vital status and information about each patient.
