Abortion Ban May Increase Risk of Death for Pregnant Women with Cancer
UCSF Perspective Article Says Ruling May Lead to Compromises in Care and Potential Loss of Life
The repercussions of overturning Roe v. Wade – and the failure of the Supreme Court to provide any guidance on exceptions related to the life and health of the mother – are potentially catastrophic for a subset of women who face a life-threating diagnosis of pregnancy associated cancers (PAC).
In their perspective article, published in JAMA Oncology, Katherine Van Loon, MD, and Jordyn Silverstein, MD, from UC San Francisco discuss the unique challenges PAC poses for women and their care teams, who must balance both safety of the mother and that of the fetus or embryo.
Approximately 1 in 1,000 pregnancies are affected by a concurrent cancer diagnosis. The most common cancers include breast cancer, cervical cancer, lymphoma, ovarian cancer, leukemia, colorectal cancer and melanoma. Termination of the pregnancy occurs in 9% to 28% of cases, with many occurring in the first trimester.
“Restrictions on pregnancy termination will primarily impact cases in which oncologic therapy is urgently needed but contraindicated in pregnancy, and the fetus is not yet viable,” writes senior author Van Loon, UCSF associate professor of clinical medicine and director of the UCSF Global Cancer Program with the Helen Diller Family Comprehensive Cancer Center. “Determinations of whether a termination can occur in a medical emergency, or with a life- threatening physical condition, will be determined by individual state laws. Oncologists who provide care in states with laws in place restricting abortion access will find themselves in precarious situations, in terms of navigating recommendations for termination based upon medical indication."
In 2020, there were a total of 3.6 million births in the United States, and 1.5 million of them (41%) were in the 26 states that will likely ban abortions. The authors estimate that at least 1,500 women will be diagnosed with PAC in the next year in states that will impose restrictions on the right to terminate a pregnancy. Based upon the occurrence rate and estimated rates of termination, they project that between 135 and 420 women with PAC will face compromises in their cancer care and potential loss of life.
Because of the complexity and multidisciplinary nature of cancer treatment during pregnancy, the authors note that the Supreme Court decision will impact oncologists’ ability to deliver optimal care in these complex cases. Particularly in cases in which the fetus is considered viable but still pre-term and therapy for the mother cannot be safely administered during pregnancy, physicians will have to balance risks of pre-term delivery versus risks of delayed cancer treatment for the mother.
“If a woman needs oncologic therapy to save her own life, physicians should not be criminalized for a decision to provide her with the best possible care,” said Van Loon.
