Fertility Preservation Decisions Among Newly Diagnosed Oncology Patients: A Single-Center Experience

To evaluate fertility preservation decisions and compare controlled ovarian stimulation (COS) and assisted reproductive technology (ART) outcomes between newly diagnosed cancer patients and age-matched healthy controls.

Our retrospective study was conducted at Columbia University's Center for Women's Reproductive Care between 2005 and 2012. Forty-nine women elected to undergo ART with COS for either oocyte or embryo cryopreservation before commencement of cancer therapy. Demographic and descriptive characteristics were collected from the cohort of patients. Treatment outcomes were compared with randomly selected, healthy, age-matched controls undergoing ART with COS during the same time period.

Single women began fertility preservation cycles in half the time of married women (10.4 vs. 22.9 d). All 21 married women chose embryo cryopreservation, whereas 17 of the 28 (61%) single women chose embryo over oocyte cryopreservation. Baseline anti-Mullerian hormone levels and body mass indices were similar among fertility preservation patients and controls. Despite elevated baseline estradiol (E2) levels and luteal phase cycle starts in some cycles to avoid delay of cancer treatment, no significant differences were noted when comparing days of stimulation, total gonadotropins prescribed, numbers of oocytes and mature oocytes retrieved, fertilization rate, or cancellation rate to controls.

Our experience shows that, with appropriate counseling and multidisciplinary care, newly diagnosed cancer patients desiring fertility preservation experience similar outcomes as age-matched healthy controls. These women can pursue oocyte or embryo cryopreservation with likely minimal disruption to the flow of their oncologic care.
