If you are 1 of the first 30 patients enrolled in the study, at the first visit you will also complete a questionnaire about your opinion of the symptom questionnaire. For example, you will be asked if the symptom questionnaire was easy to understand and to complete and if there were any other questions that should be included. The study staff will use your opinion to decide if other important symptom questions are missing from the questionnaire. This questionnaire should take about 5 minutes to complete.
