Intervention: Neurocognitive Assessment
Description: All patients at MSKCC will complete a neurocognitive test battery at study entry (prior to RT), and approximately 3, 6 and 12 months and post -RT. The neurocognitive tests consists of standardized, validated and reliable measures of attention, executive functions, and memory, for which age- and education-matched healthy control published data are available. Patients will also complete self-report mood and fatigue scales at each of the same time points. This testing will only be done at MSKCC. Non-English-speaking patients and pediatric patients are exempt from completing the neurocognitive assessments. Neurocognitive assessments will be performed in person at MSK-Manhattan; an option to perform follow up assessments via telehealth will be available only for patients who are not able to go to Manhattan for these visits.
