All patients will have complete checkups, including blood and urine tests 2 or 3 times during the first 12 weeks of the study. Tumors will be measured by CT or MRI and gallium scans. Patients will be asked to fill out a survey about quality of life issues (maintaining normal routine, family life, social life, pain). It takes about half an hour to fill out the survey. A bone marrow sample may be taken. A test of heart function will be done. Checkups and tests will be done every 3 months for 1 year and then every 6 months for 4 more years.
