Approximately 6 months after completion of therapy patients receive a mailed packet introducing the Long-Term Follow-Up Center (LTFC) and containing information related to their individualized, protocol-specific follow-up guidelines. Patients are asked to complete a patient response form, verify information provided in packet, update contact information, and complete a Health Status Update Form. The Health Status Update Form is a brief document including questions about current health status, disease status, and cancer therapy received since the last mailing. Patients receive protocol-specific automatic reminders, and may respond by use of postage prepaid envelopes, email, or 24-hour toll-free telephone number.
