This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
The growing U.S. cancer survivor population is projected to hit 26M by 2040. Chemotherapy represents an effective cancer treatment but can diminish cancer survivors' quality of life-particularly cognitive function-through select pathophysiological processes. Research on chemotherapy-induced cognitive impairment (hereafter, 'chemo-brain') is therefore critical. Chemotherapy disrupts immune system function and antioxidant regulation, causing inflammatory molecule release and damaging the brain's blood vessels. The brain's vascular function and, possibly, its neurons, are subsequently impaired-likely contributing to chemo-brain. Type 2 diabetes (T2D), a common cancer survivor comorbidity, shares underlying pathophysiology with chemo-brain. T2D-related insulin resistance can precipitate repeated high blood sugar episodes which increase inflammatory molecule release. In individuals with T2D without cancer, negative relationships are observed between inflammatory molecule concentrations and the brain's vascular and/or cognitive function. Cancer survivors with T2D might thus have higher chemo-brain risk than those without T2D. Yet, more research must compare how the brain's vascular function, as well as cognitive, inflammatory, and cardiometabolic indices, differ between these groups. Physical activity (PA) counteracts chemo-brain's and T2D's pathophysiology, with higher PA/fitness resulting in better vascular function of the brain, lower inflammatory molecule concentrations, and improved insulin sensitivity. We are therefore conducting a 30-participant quasi-experimental pilot study in cancer survivors with (cases) and without (controls) T2D. We will first investigate between-group differences in the brain's vascular function as well as cognitive, inflammatory, cardiometabolic, and epigenetic outcomes. We will then examine between-group changes in these outcomes and select psychosocial metrics during a 12-week technology-based PA program-potentially further elucidating involved mechanisms.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
