Obstructive Sleep Apnea in Survivors of Hodgkin Lymphoma Treated With Thoracic Radiation (NCT03361020)

🩺 Plain-English Summary (8th-Grade Level)

While thoracic radiation therapy (TRT) has been a primary component in successful treatment of Hodgkin lymphoma, exposure to this treatment has been associated with significant cardiovascular, cerebrovascular, and pulmonary morbidity in long-term survivors. Survivors of Hodgkin lymphoma (HL) are also at risk for fatigue and excessive daytime sleepiness. Insufficient sleep is recognized as an important public health concern, and is associated with cardiovascular disease, diabetes, obesity, neurocognitive problems, and reduced quality of life and productivity. Survivors of HL, who are already at risk for cardiac and neurologic morbidity due to their treatment exposures, could face catastrophic cardiovascular and cerebrovascular events with the added risk associated with obstructive sleep apnea (OSA). The investigators propose to examine indices of sleep quality using polysomnography, and associated neurocognitive performance, brain MRI, and structure and strength of neck muscles in 220 long-term adult survivors of Hodgkin lymphoma treated with thoracic radiation. OBJECTIVES: 1. To estimate the prevalence of OSA in adult survivors of HL treated with thoracic radiation, and compare the frequency to community controls matched on age, gender, race and body mass index. 2. To identify specific therapeutic factors associated with OSA in adult survivors of HL treated with thoracic radiation. 3. To identify biomarkers of OSA in adult survivors of HL treated with thoracic radiation. 4. To examine associations between OSA and cardiac morbidity and brain integrity in the adult survivors of HL treated with thoracic radiation.
