- Self-reported cancer is a valuable epidemiological tool for
identifying cases in cohort studies. The cost, time, and
resources required, in addition to the efficiency in ascertaining
cases, need to be considered when deciding between
active and passive follow-up approaches. Because Korean
families hold a family-centered approach when making decisions
(1), it is not uncommon for patients to be unaware of
their cancer diagnosis or status. A total of 20% of physicians
and 33% of family members opposed patient notification of
his or her disease status (2), and only 35% of Korean-Americans
would tell a patient about a terminal prognosis (1).
Because of these cultural differences and, thus, inaccuracies
in self-reported information that arise, there is a need to
examine the appropriateness of the active follow-up approach in ascertaining incident cancer cases. The objectives
of the study were to assess the validity and reliability
of self-reported cancer at follow-up and to examine the relative
efficiencies of the active and passive follow-up methods
in identifying incident cancer cases.
