Effect of chemotherapy on the uterus of young adult cancer survivors.

Objective: To investigate the impact of chemotherapy on the uterus. Design: Cross-sectional pilot study. Setting: Single university fertility clinic. Patients: Twelve patients with a history of alkylating agent chemotherapy exposure after Hodgkin lymphoma (cancer) vs. 12 normally menstruating women (controls). Interventions: The inclusion criteria were age of 18-45 years and consent for endometrial biopsy. The exclusion criteria were the absence of the uterus, completed pelvic radiation, uterine or cervical cancer, and metastatic cancer. Each participant underwent endometrial biopsy and pelvic ultrasound. All study visits were conducted in the late proliferative phase of the menstrual cycle. Main Outcome Measures: Uterine volume, blood flow, endometrial thickness, histology, deoxyribonucleic acid methylation pattern, and relative ribonucleic acid (RNA) expression level during the same phase of the menstrual cycle. Results: In the study group, visits were conducted at a median of 31.5 (13.5-42.5) months after chemotherapy. The median uterine volume among cancer survivors was 36 (11.3-67) cm Conclusions: Approximately 2.5 years after chemotherapy, a time at which several survivors of Hodgkin lymphoma may resume family-building, endometrial thickness and endometrial histology were not significantly affected by a history of alkylating agent chemotherapy exposure.
