Prevalence of conception and pregnancy outcomes after hematopoietic cell transplantation: Report from the bone marrow transplant survivor study
We conducted a retrospective study to describe the magnitude of compromise in reproductive function and investigate pregnancy outcomes in 619 women and partners of men treated with autologous (n=241) or allogeneic (n=378) hematopoietic cell transplantation (HCT) between 21 and 45 years of age, and surviving 2 or more years. Median age at HCT was 33.3 years and median time since HCT 7.7 years. Mailed questionnaires captured pregnancies and their outcomes (live birth, stillbirth, miscarriage). Thirty-four patients reported 54 pregnancies after HCT (26 males, 40 pregnancies; eight females, 14 pregnancies), of which 46 resulted in live births. Factors associated with reporting no conception included older age at HCT (≥30 years: odds ratio (OR)=4.8), female sex (OR=3.0), and total body irradiation (OR=3.3). Prevalence of conception and pregnancy outcomes in HCT survivors were compared to those of 301 nearest-age siblings. Although the risk for not reporting a conception was significantly increased among HCT survivors (OR=36), survivors were not significantly more likely than siblings to report miscarriage or stillbirth (OR=0.7). Although prevalence of conception is diminished after HCT, if pregnancy does occur, outcome is likely to be favorable. Patients should be counseled prior to transplant regarding strategies to preserve fertility. © 2006 Nature Publishing Group. All rights reserved.
