The Longitudinal Ovarian Reserve Study

Effects of Chemotherapy Clinical Trial

Official title: The Effects of Cancer Treatment on Ovarian Function: A Longitudinal Study by the Oncofertility Consortium

Status Completed

Clinical Trial Summary

Postmenarchal female cancer patients scheduled to undergo cancer therapy may enroll in this study to assess changes in existing and novel surrogate measures of fertility potential before, during and after chemotherapy. Measures of fertility potential to be tested include ultrasound imaging for antral follicle counts and ovarian volumes, endocrine evaluation, and assessment of oxidative stress.

Clinical Trial Description

Eligible women are asked to complete a structured interview, questionnaires, a monthly menstrual diary, a brief physical examination, a blood test, and an abdominal or pelvic ultrasound at baseline and at 3 month intervals following start of chemotherapy through 6 months post end of treatment.

Within subject changes in continuous variables (hormones, urinary isoprostane levels, ovarian volume, AFC) will be compared using paired t-tests (nonparametric tests as appropriate). Non-Gaussian-distributed variables will be logarithmically transformed prior to analysis. In general, changes from baseline to every 3 month assessment will be compared individually as well as changes from baseline to post treatment. In addition, regression models for repeated measures will be used to describe the pattern of change in these outcomes over time. Additional models will be constructed to adjust for potential confounding variables including age, chemotherapy type, dose and duration of treatment, radiation treatment, gonadotropin releasing hormone agonist use, and hormone use. Finally, regression models will be used to evaluate the association between changes in urinary isoprostane levels over the study with changes in endocrine measures. ;
