Fertility concerns and preservation in younger women with breast cancer.
Nearly 30% of breast cancer cases present in women younger than 50 years old. While newer treatment regimens employed are less gonadotoxic, regimens still consist of combination medications that include cyclophosphamide, known to deplete the number of primordial follicles, thereby potentially leading to infertility. For common regimens such as adriamycin/cytoxan (AC), the risk of premature ovarian failure was thought to be largely dependent on patient age, with the risk of complete ovarian failure <10% in women <30, and nearly 100% in women >40 (Hortobagyi et al. (1986) [1]); however recent studies indicate that AC is considered to have intermediate risk for gonadotoxicity in women >40 years age. This review examines major strides in the field of reproductive medicine over the past 20 years including the use of leuprolide acetate, embryo cryopreservation, oocyte cryopreservation and ovarian tissue banking. We also discuss the role of gestational carriers and adoption in establishing families as a viable option for many of these cancer patients who may be unable to avail themselves of other alternatives to fertility preservation.
