This study, called HODNIRS, is looking at how Hodgkin Lymphoma (HL) survivors who received bleomycin and/or chest radiation therapy at St. Jude Children's Research Hospital are doing. Researchers want to understand if there's a connection between these past treatments and brain function. They will use a portable, non-invasive (meaning it doesn't go inside your body) device called Near-Infrared Spectroscopy (NIRS) to measure blood flow and oxygen in the brain during exercise. The study aims to compare these measurements in HL survivors to people who haven't had cancer. You might be able to join if you are an HL survivor treated at St. Jude, were under 21 at diagnosis, are now at least 18 and at least 2 years past treatment, and speak English. Community controls who are at least 18 years old can also join.

Study design

This is an observational study planning to include 100 participants, including Hodgkin Lymphoma survivors and community controls.

What's involved

You would have your brain blood flow and oxygen measured using a wearable NIRS device during physical activity at baseline.
