简要总结
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.
详细描述
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.

结局指标
主要结局
Infertility
时间窗: Up to 4 years
The American Society of Reproductive Medicine's definition of "infertility" as "... the failure to achieve a successful pregnancy after 12 months or more of regular unprotected intercourse" will be used to categorize patients as to a history of infertility. Based on interview questions regarding each subject's personal and partner's history of medical investigations and treatment for infertility, an attempt will be made to further distinguish each subject's history of infertility as being due to the male (study subject), the female or indeterminate. Will determine whether infertility differ in male osteosarcoma survivors treated with cisplatin with or without ifosfamide compared to male controls without a history of cancer. Will be analyzed using unconditional logistic regression models to estimate odds ratios and 95% confidence intervals for the associations of chemotherapy group with abnormal values as defined in clinical practice.
Sperm concentration
时间窗: Up to 4 years
Sperm concentration (per mL) will be assessed by Computer Assisted Sperm Analysis. Three separate counts will be performed and the results averaged. Will be analyzed using unconditional logistic regression models to estimate odds ratios and 95% confidence intervals for the associations of chemotherapy group with abnormal values as defined in clinical practice.
Luteinizing hormone levels
时间窗: Up to 4 years
Will be measured by immunofluorometric assay. Will be analyzed using unconditional logistic regression models to estimate odds ratios and 95% confidence intervals for the associations of chemotherapy group with abnormal values as defined in clinical practice.
Testosterone levels
时间窗: Up to 4 years
Will be measured by radioimmunoassay. Will be analyzed using unconditional logistic regression models to estimate odds ratios and 95% confidence intervals for the associations of chemotherapy group with abnormal values as defined in clinical practice.
Follicle stimulating hormone levels
时间窗: Up to 4 years
Will be measured by immunofluorometric assay. Will be analyzed using unconditional logistic regression models to estimate odds ratios and 95% confidence intervals for the associations of chemotherapy group with abnormal values as defined in clinical practice.
Serum inhibin B
时间窗: Up to 4 years
Will be measured by enzyme-linked immunosorbent assay. Will be analyzed using unconditional logistic regression models to estimate odds ratios and 95% confidence intervals for the associations of chemotherapy group with abnormal values as defined in clinical practice.
Sperm morphology
时间窗: Up to 4 years
Sperm morphology will be assessed. Will be analyzed using unconditional logistic regression models to estimate odds ratios and 95% confidence intervals for the associations of chemotherapy group with abnormal values as defined in clinical practice.
Sperm deoxyribonucleic acid methylation
时间窗: Up to 4 years
Genome-wide differentially methylated regions will be identified using methylated deoxyribonucleic acid immunoprecipitation followed by next generation sequencing analysis methylated deoxyribonucleic acid immunoprecipitation sequencing using pooled deoxyribonucleic acid. Sperm deoxyribonucleic acid differentially methylated regions will be confirmed in the pooled samples by bisulfite treatment of genomic deoxyribonucleic acid to convert cytosine to thymine followed by next generation sequencing for a bisulfite-sequencing analysis. Thus, methylated deoxyribonucleic acid immunoprecipitation- sequencing is used to identify the differentially methylated regions and bisulfite sequencing used to confirm the differentially methylated regions at the CpG level resolution. Pyrosequencing will be used involving next generation sequencing after polymerase chain reaction of individual sperm deoxyribonucleic acid samples to assess individual differentially methylated regions.
