 If you are one of the first 20 patients enrolled in the study, you will be asked questions about your opinion of the symptom questionnaire. For example, you will be asked if the symptom questionnaire was easy to understand and complete, and if there were any other questions that should be included. The study staff will use your opinion to decide if changes should be made to the questionnaire or if important symptom questions are missing from the questionnaire. This questionnaire should take about 5 minutes to complete.
