Is Chemotherapy an Emergency When Fertility Is at Risk?
A 20-year-old married female presents to the emergency room with a white blood cell count of 800,000. She informs the medical team she is 10 weeks pregnant and shortly after begins to complain of abdominal pain. After a rapid and extensive workup, the medical team informs the patient she has suffered a miscarriage and possibly has newly diagnosed leukemia. After moments of sobbing with her husband, the patient looks up at the physician and says “This was my miracle baby. Will I be able to have another baby?”
The ability to conceive and have a child is often on the minds of patients during childbearing age when they are diagnosed with cancer. Chemotherapy, radiation, hormone therapy, and even stem cell transplantation has the ability to cause infertility. These therapies can interfere with uterine function, prevention of ovaries from being released, and/or fetuses from being carried full term leading to miscarriage. In men, these drugs can impact their erection and ability to produce semen. Drugs such as busulfan, carmustine, cyclophosphamide, doxorubicin, melphalan, thiotepa, and vincristine are commonly given in high doses that can cause permanent damage to fertility. Hormones such as Tamoxifen can interfere with the ability to have children as well as induce birth defects. Targeted therapies such as bevacizumab (Avastin) can lead to permanent ovary damage and thalidomide can cause birth defects. And finally prior to stem cell transplantation, high dose chemotherapy and radiation are given which lead to a disruption eggs from being released from the ovaries.
The American Society of Clinical Oncology recommends those with cancer discuss the risk of infertility and preservation prior to starting chemotherapy. Even if the medical and nursing staff do not initiate the conversation, it is important that patients advocate for themselves to ensure they are equal partners in their care. Those who choose not to discuss their fertility prior to therapy may still have children after treatment however they should wait one year before conceiving. In the event, a patient is pregnant at diagnosis, therapy can be given to preserve the fetus until safe to electively deliver with minimal risk.
So, is chemotherapy an emergency? Not necessarily.
