Pregnancy and cancer: A delicate balance
The Challenge: Balancing Motherhood and Cancer Care
A new guideline from the American Society of Clinical Oncology (ASCO) sheds light on the complex issue of cancer care during pregnancy. While rare, cancer diagnoses in pregnant women require a careful consideration of the mother's health and the fetus's well-being. This delicate balance is a challenging task for healthcare providers, as they must navigate the needs and preferences of the expectant mother while also addressing the health of the developing baby.
The Statistics: A Rare but Significant Concern
According to Dr. Mikkael A. Sekeres, a coauthor of the guideline and chief of the Division of Hematology at Sylvester Comprehensive Cancer Center in Miami, cancer diagnoses in pregnancy are uncommon, occurring in only about one in 1000-2000 pregnancies. However, the implications are profound, as the health of both mother and fetus must be considered. This rare event highlights the need for specialized care and a multidisciplinary approach.
The Guideline: Evidence-Based Recommendations
The ASCO guideline, published in the Journal of Clinical Oncology, provides evidence-based recommendations for the diagnosis, management, and obstetrical considerations of pregnant patients with cancer. While the quality of evidence is generally low, based on retrospective studies and case reports, the guideline authors deem the recommendations strong, offering valuable real-world data for clinical practice.
The Key Considerations: Balancing Care and Risks
Dr. Ann H. Partridge, a coauthor and director of the Adult Survivorship Program at Dana-Farber Cancer Institute in Boston, emphasizes the importance of understanding the patient's preferences and weighing the risks of the disease and treatment options. She highlights the need to consider the patient's goals, the aggressiveness of the cancer, and the potential risks to the fetus, both from the disease and from the treatment itself.
The Multidisciplinary Approach: Collaborating for Optimal Care
The guideline recommends that pregnant patients with cancer be cared for by a multidisciplinary team, including pharmacists, who can collaborate to develop and adjust individualized treatment plans. Clinicians across disciplines should engage patients and caregivers in informed consent discussions before starting or continuing any form of therapy.
Patient Autonomy and Personal Preference: Prioritizing Individual Needs
The guideline also emphasizes the importance of patient autonomy and personal preference. Cancer may result in medical emergencies that require immediate cancer-directed therapy, and in such cases, termination of the pregnancy may be necessary to prevent the patient's death or mitigate the risk of death. However, the guideline also acknowledges the importance of considering the patient's goals and preferences in the decision-making process.
The Use of Drugs with Unknown Teratogenic Potential: A Challenging Area
One of the most fraught considerations is the use of drugs with unknown teratogenic potential. Dr. Sekeres notes that the evidence for these drugs is limited, and while newer therapies are not exempt from this challenge, pregnant patients are often excluded from trials, leading to a lack of data and a need for careful consideration of the risks and benefits.
The Future: Ongoing Research and Discussion
The guideline serves as a starting point for discussion and further research. Dr. Partridge highlights the need for ongoing dialogue and collaboration among healthcare providers, researchers, and patients to better understand the risks and benefits of cancer care during pregnancy. The ASCO guideline provides a foundation for this discussion, inviting further exploration and adaptation to individual patient needs.
