Trials stop following patients after a few years, so late side effects and late relapses are missed. Link trial participants to national records so follow-up continues automatically for decades.
Late effects of cancer treatment (second cancers, cardiac disease, endocrine failure) appear decades later, long after trials close. The Childhood Cancer Survivor Study shows the value of long follow-up but relies on costly active contact. The proposal requires consent for registry linkage in every publicly funded trial and funds automated linkage of trial participants to cancer, death and hospital records for 30 years, with pooled analysis across trials.
