Cancer survival statistics derived from population-based cancer registry data provide important measures for cancer control efforts. Information about vital status after diagnosis for every cancer patient is essential to this purpose, yet can be challenging to collect, particularly for immigrants who leave the country to obtain cancer care and/or to die abroad. Such “medical” migration may partly explain the “healthy immigrant effect,” or, among the US Hispanic population, the “Hispanic paradox”, which notes that some immigrant groups have better cancer and other health outcomes than their socioeconomic conditions would predict. This cancer registry-based study will systematically examine the follow-up process and procedures within the California Cancer Registry, identify patient subgroups with differential follow-up, and develop and propose approaches for addressing differential follow-up.
