If you agree to take part in this study, you may be asked to fill out a questionnaire called the MD Anderson Symptom Inventory (MDASI) before your scheduled pleural effusion treatment procedure, 24 hours after your procedure, and then weekly for the next 4 months. During this time, a member of the study staff or a computer system will call you at home on your desired day and time to complete the questionnaire. The MDASI for lung-related symptoms has 22 questions about the possible symptoms caused by the disease, and how the symptoms may affect the activities of your daily life, which you will rate on a scale of 0-10. The MDASI will take about 5 minutes to complete each time.
