Kagramanov D, Sutradhar R, Lau C, et al. - Given lifelong healthcare is needed for adolescent and young adult cancer survivors in order to address the late impacts of therapy, researchers undertook this retrospective cohort study in Ontario, Canada, to determine the influence of different provider models of long-term follow-up (LTFU) care on adherence to recommended surveillance. Three models of LTFU care were described hierarchically: specialized survivor clinics (SCCs), general cancer clinics (GCCs), and family physician. This analysis included 1574 survivors. In the first 2-years post-index, a GCC (47%) was the highest level of LTFU attended; only 16.7% attended a SCC. By the close of study, 72% no longer attended any of the models of care and, an SCC was still attended by only 2%. Findings revealed sub-optimal LTFU attendance as well as surveillance adherence. SCC follow-up was shown to be related to greater adherence, but such care was received by few survivors, and this proportion declined over time. There is a requirement for interventions to improve LTFU attendance and encourage surveillance adherence.
