This research trial studies saliva, semen, and blood samples to determine effects of chemotherapy on fertility in osteosarcoma survivors. Study biospecimen samples from osteosarcoma survivors in the laboratory may help doctors learn whether chemotherapy causes fertility problems and to learn more about the long term effects.

Official Title

Effects of Modern Chemotherapy Regimens on Spermatogenesis and Steroidogenesis in Adolescent and Young Adult (AYA) Survivors of Osteosarcoma


PRIMARY OBJECTIVES: I. Determine whether infertility and/or biomarkers of spermatogenesis and steroidogenesis differ in male osteosarcoma survivors treated with cisplatin with or without ifosfamide compared to male controls without a history of cancer. II. Evaluate whether cisplatin with or without ifosfamide for the treatment of osteosarcoma alters sperm deoxyribonucleic acid (DNA) methylation. EXPLORATORY OBJECTIVES: I. Evaluate the role of genetic susceptibility in the development of impairments in spermatogenesis or steroidogenesis with contemporary regimens for the treatment of osteosarcoma. OUTLINE: Participants complete a health questionnaire over 30-45 minutes. Patients also provide saliva and semen samples and undergo collection of blood.
