Brain Integrity in Survivors of Hodgkin Lymphoma Treated With Thoracic Radiation
Brain Integrity in Survivors of Hodgkin Lymphoma (HL) Treated With Thoracic Radiation
While thoracic radiation therapy (TRT) has been a primary component in successful treatment of a variety of childhood and adult cancers, the exposure to this treatment has been associated with significant cardiovascular and pulmonary morbidity in long-term survivors. Within non-cancer populations, cardiovascular and pulmonary morbidity is associated with increased risk for cerebral vascular accidents (CVAs), accelerated brain atrophy and neurocognitive impairment. Patients with chronic heart disease demonstrate problems with attention, processing speed, memory, and executive functions. Chronic pulmonary disease also increases the risk of stroke, leukoencephalopathy, and neurocognitive impairment in non-cancer populations. The investigators propose to examine indices of brain integrity, including neurocognitive performance and brain MRI/MRA, in long-term adult survivors of Hodgkin lymphoma (HL) treated with thoracic radiation and no direct central nervous system therapy.
OBJECTIVES:
- To evaluate brain integrity in adult survivors of childhood HL treated with thoracic radiation therapy.
- To identify therapeutic factors associated with brain integrity in adult survivors of childhood HL who are at risk for cardiac and pulmonary morbidity.
- To examine associations between cardiac, vascular and pulmonary health and brain integrity in adult survivors of childhood HL treated with thoracic radiation.
調査の概要

詳細な説明
This is an observational study to collect health data from long-term survivors of Hodgkin lymphoma (HL). Data will be collected once at participant enrollment. The long-term effects of thoracic radiation therapy (TRT) given earlier as part of the treatment for HL will be examined in long-term survivors and compared to health data collected from normal volunteers.
HL survivors who were treated at St. Jude Children's Research Hospital (SJCRH) with TRT will be recruited to complete a comprehensive neurocognitive evaluation, brain MRI/MRA, a clinical neurological exam, peripheral pulse contour analysis, non-invasive central blood pressure monitoring, cardiopulmonary exercise testing, and serum biomarkers related to cardiac disease. As part of their standard St. Jude LIFE protocol evaluation, they also complete an echocardiogram, pulmonary function tests and questionnaires designed to evaluate broad health, psychological, socioeconomic and environmental factors that impact everyday life.
A comparison sample of healthy individuals, frequency-matched on age, sex and race will also be recruited. The comparison group will complete the comprehensive neurocognitive evaluation, brain MRI/MRA, clinical neurological exam, pulse contour analysis, non-invasive central blood pressure monitoring, and cardiopulmonary exercise testing. Through the St. Jude LIFE protocol, the comparison sample will also complete an echocardiogram, pulmonary function tests and questionnaires designed to evaluate broad health, psychological, socioeconomic and environmental factors that impact everyday life.

調査対象母集団
SJLIFE is an institutional initiative to establish a lifetime survivor cohort to study physical and behavioral health outcomes in adult survivors of childhood cancer. This protocol includes individuals diagnosed and treated with a malignancy during childhood at SJCRH since 1962, who are now 10 or more years from diagnosis and over 18 years of age.
The current study will recruit participants from the SJLIFE cohort who received thoracic radiation as part of their treatment for Hodgkin lymphoma.
Potentially eligible comparison group participants will be recruited from the relative or friend population who accompany any After Completion of Therapy (ACT) or SJLIFE patient for follow-up at SJCRH.

Hodgkin lymphoma
Participants previously treated at St. Jude Children's Research Hospital with thoracic radiation therapy for Hodgkin lymphoma. Interventions: Neurocognitive Evaluation, Quantitative Brain Imaging, Neurologic Evaluation, Comprehensive Health Questionnaire, Vascular Testing, Cardiopulmonary Exercise Testing, Echocardiography, Pulmonary Function Testing, Serum Biomarkers, and Ophthalmology Examination. |
The neurocognitive evaluation will include measures of academic achievement, intelligence, sustained attention, memory, processing speed, executive functions, functional behavior, and emotional functioning.
Imaging will include raw images to both quantify white matter hyperintensities and hemosiderin deposits, as well as cortical thickness and tissue segmentation.
Brain imaging will be repeated on participants who are concurrently enrolled on BRIGHT and MIND protocols at St. Jude and who completed prior brain imaging during the BRIGHT clinic visit.
The repeat MRI will be done at their 6 month MIND clinic visit.
Evaluation includes a complete review of neurologic symptoms, and interview and examination by the neurologist, assessment of neurologic symptoms and determination of their impact on day-to-day living, and quantified neurologic examination by the neurologist.
Participants will be asked to complete an approximately 450-item survey to assess health history and status, social and demographic factors, health behaviors, and psychosocial constructs.
Digital assessment of endothelial function will be studied, and central blood and pulse pressure and carotid-femoral pulse wave velocity will be non-invasively measured.
Study participants will undergo cardiopulmonary exercise testing by treadmill.
Those participants whose physical performance does not permit walking safely on the treadmill (extreme deconditioning, lower extremity paralysis, balance disorder, acute lower extremity injury) will perform cardiopulmonary exercise testing on a bicycle or upper extremity ergometer using a comparable testing protocol.
A complete 3D as well as 2D echocardiogram with Doppler and M-mode will be performed.
Pulmonary function testing will include spirometry, lung volume measurements by body plethysmography, and single-breath carbon monoxide-diffusion capacity (DLCO).
Blood for serum biomarkers associated with cardiovascular morbidity will be drawn, including high-sensitivity C-reactive protein, serum homocysteine.
Ophthalmology examination will include a review of symptoms, examination, and fundus imaging.
The examination will consist of visual acuity testing, refraction testing, retinoscopy, ocular pressure, and examination under mydriasis.
Fundus photography will be used to capture an image of the retina for examination of potential hypertensive retinopathy.

Association between thoracic radiation dose and sustained attention and memory scores and rate of leukoencephalopathy and hemosiderin deposits in HL survivors.
時間枠：Once, at or near enrollment
|
In HL survivors only, outcome variables will be: sustained attention (continuous), memory (continuous), leukoencephalopathy (dichotomous) and hemosiderin deposits (dichotomous).
Independent variables are radiation dose to cardiopulmonary structures.
Covariates will include chemotherapy exposures, particularly anthracycline exposure.
For each continuous response variable, linear regression model will be used to see its association with these independent variables, adjusted for race/age/sex.
Other possible covariates include educational attainment, employment and occupation, current physical activity, and alcohol and tobacco.
For each dichotomous response variable, logistic regression model will be used to see its association with these independent variables, adjusted for race/age/sex.
AIC criteria will be used to select the final model.
