View original scientific description
SURVIVORS Study participants are being asked to take part in this research study called HODNIRS because the participant is a survivor of Hodgkin Lymphoma (HL) treated with chest radiation and bleomycin at St. Jude Children's Research Hospital. The study is being done to help investigators understand the link between long term effects of chest radiation and bleomycin for HL and brain function in survivors. Primary Objective To evaluate dynamic changes in CBF and oxygenation during exercise with Near Infrared Spectroscopy (NIRS) in HL survivors and non-cancer controls matched for age, sex, race, and ethnicity. . Secondary Objectives To examine the degree of CO2 clearance (DLCO/ETCO2) during rest and exercise in Hodgkin Lymphoma (HL) survivors compared to non-cancer controls matched for age, sex, race, and ethnicity. CONTROLS Volunteers are being asked to take part in this research study because they are non-first degree relative or friend of someone who received treatment for a childhood cancer or similar illness at St. Jude Children's Research Hospital or are an employee/affiliate of St. Jude Children's Research Hospital and have agreed to be a St. Jude Life Cohort Study (SJLIFE) community control.
Interventions
DEVICE
Near Infrared Spectroscopy (NIRS)
NIRS is a portable, non-invasive, brain imaging device.
Primary outcome measures
Near-Infrared Spectroscopy (NIRS)
Time frame: Baseline
a non-invasive imaging technology that is used to measure regional or global cerebral tissue oxygenation and cerebral blood flow (CBF) during exercise. NIRS takes advantage of the fact that oxygenated blood and de-oxygenated blood absorb light differently. By measuring the reflected light from blood, the concentration of both oxygenated hemoglobin (HbO2) and deoxygenated hemoglobin (HbdO2) using the modified Beer-Lambert Law can be calculated.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria

- \<21-years old at diagnosis; currently ≥18-years of age and ≥2-years post therapy.
- SJLIFE or ACT/SJLIFE participants
- English language proficiency. Community Controls
- SJLIFE control.
- ≥18-years of age at the time of enrollment with age sampling to broadly match the HL survivors.
Exclusion criteria
- HL Survivors
- History of cranial or total-body irradiation therapy.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
