Late Effects of Treatment for Sarcomas in Children

Study Overview
=================
Brief Summary
-----------------
This study will examine late effects of treatment for sarcoma (bone and soft tissue cancers) in children. Survival of patients with these diseases has improved over the years, but long-term adverse effects of treatment have also been noted. Patients previously treated for sarcoma in the NCI's Pediatric Oncology Branch who are in their first remission from sarcoma after completion of therapy and who have had no further cancer treatment (chemotherapy, radiation therapy, cancer related surgery or immunotherapy) for at least 24 months may be eligible for this 3- to 4-day study. It will review the incidence and extent of the following late effects of therapy. Heart problems-The chemotherapy drug doxorubicin can cause acute and late injuries to the heart muscle. Patients will undergo magnetic resonance imaging (MRI) of the heart to look for changes and compare the findings with information obtained by standard echocardiogram (ultrasound test of the heart) and by MUGA (nuclear medicine scan of the heart). Gonadal dysfunction-The chemotherapy drug cyclophosphamide may affect sex hormone production, leading to infertility, early menopause or brittle bones. Low sex hormone levels may also increase the risk for heart attack, obesity or fracture. Patients will have blood tests to measure hormone levels as well as mineral levels, lipid levels and blood cell counts. They will also have a DEXA scan to measure bone mineral density and a CT scan of the abdomen to evaluate the distribution of fatty tissue in the abdomen. Males will be offered a semen analysis as part of the fertility evaluation. Psychosocial problems- Cancer diagnosis and treatment pose a major life stress that can lead to problems with personal relationships, jobs, insurance, education, health care, and personal and professional goal setting. Some patients may become depressed or develop a psychiatric illness. Patients will fill out a questionnaire about their treatment, recovery, and aspects of their current life and will meet with a psychologist and psychiatrist. Changes in bodily function and capabilities-Patients who undergo surgery and radiation to treat sarcoma treatment may experience muscle, bone and joint changes. Patients will be interviewed about their performance of daily activities, physical limitations, and changes in skill levels. They will do a series of exercises and will have measurements of strength, mobility and physical skills, focusing on the parts of the body that were affected by the sarcoma and subsequent local therapy. Exposure to viruses-A number of patients received blood transfusions as part of their cancer treatment. Some transfusions were given before HIV screening became available. Patients will be tested for this virus as well as the hepatitis virus and HTLV-1 (human T-cell leukemia virus-1), for which there are also small transfusion-associated risks. Kidney function-The chemotherapy drug ifosfamide may affect kidney function. Patients will provide a urine specimen for kidney function tests. Immune function-Chemotherapy affects the function of infection-fighting immune cells called T-lymphocytes. A blood sample will be drawn for studies of the time involved in recovering full immune function.

Detailed Description
-----------------
Childhood cancers mark a relatively infrequent disease entity with an annual age adjusted rate in children age 0-14 years of 14 per 100,000. Over the last 30 years a striking increase in survival due to improved diagnosis and aggressive treatment approaches has vastly enhanced the outlook in this patient population. 75% of children under 15 years age of can be expected to survive the diagnosis of cancer for more than 5 years. However, reports of improved survival have been followed by increasing awareness of a multitude of long-term treatment-related side effects, in addition to an overall death rate 9.6 times higher than in the sex- and age-matched general population. Over the last 35 years, patients with pediatric sarcomas have been treated in the Pediatric Oncology Branch (POB) of the National Cancer Institute. Since 1971 adriamycin and cyclophosphamide in escalating doses have been incorporated in all multimodality treatment protocols. Ifosfamide became an integral part of therapy in 1986. The survival rate of patients with these diseases has improved over this period of time. Accordingly there exists a group of long-term survivors of therapy employed in a series of POB sarcoma protocols who represent a valuable source of information on treatment-associated late-effects, e.g. cardiotoxicity, gonadal dysfunction, growth delay and stress-related neuroendocrine abnormalities. In addition there may be evaluable rehabilitative impairments and alterations in psychosocial behavior that may only manifest over time, and prove to be characteristic for this population. This protocol will systematically enumerate and describe the incidence and extent of treatment related long-term toxicities in this patient population.

Eligibility Criteria
-----------------
INCLUSION CRITERIA: Diagnosis of sarcoma. Previous enrollment on one of the POB protocols or enrollment on the Natural History protocol and treated according to POB outlines for the treatment of sarcomas. Chemotherapy delivered according to one of previous POB trials. Patients must be either in first continued remission from sarcoma after completion of therapy, or in continued remission of more than 5 years after completion of salvage therapy for disease relapse. Patients must have had no chemotherapy, radiation therapy, cancer related surgery and/or immunotherapy for at least 24 months. Patients must have had stable disease greater than 24 months or be NED by history. Must be able to travel to NCI/POB. Alternatively, subjects may consent on a separate consent document to the mail-in questionnaire component of the study only, which will not require travel to the NIH. Must be able to understand and sign consent. Minors must be accompanied by a parent or guardian legally permitted to give consent. Written assent will be obtained from all minors age 12 years or older. Patients who elect to complete the mail-in questionnaire must be greater than or equal to 18 years old. Negative pregnancy test in all female patients. Pregnant or lactating women are ineligible for study enrollment while they are pregnant or lactating, but may be enrolled at a later point once these conditions have ceased to exist. For eligible subjects consenting to participation in the mail-in questionnaire component of the study only, a urine pregnancy test will not be required.
