Patients complete Linear Anologue Self Assessment (LASA) and Symptoms Distress Scale (SDS) questionnaires, including fatigue, diarrhea, and rash assessment, at baseline, after 2-3, 5-6, and 18 months of treatment, and 5 years after completion of treatment. Patients are also randomized to 1 of 2 arms to complete additional quality of life questionnaires at these same time points.
