Radiation therapy during pregnancy poses significant challenges, balancing maternal cancer treatment with fetal safety. Minimizing fetal radiation dose is crucial, with decisions made by a multidisciplinary team.

Area of Science:

  • Oncology
  • Radiation Oncology
  • Maternal-Fetal Medicine

Background:

  • Malignant diseases requiring radiation therapy during pregnancy present complex clinical challenges.
  • Conflicting demands exist between optimal cancer treatment and pregnancy management.
  • Ionizing radiation exposure during gestation requires careful consideration due to potential fetal harm.

Purpose of the Study:

  • To outline the challenges and considerations for managing pregnant patients requiring radiation therapy.
  • To emphasize the importance of minimizing fetal radiation dose.
  • To guide decision-making regarding treatment timing, modality, and pregnancy management.

Main Methods:

  • Review of existing literature and clinical guidelines on radiation therapy in pregnancy.

  • Discussion of risks associated with fetal radiation exposure (e.g., >0.1 Gy).
  • Emphasis on multidisciplinary team approach involving oncologists, radiation oncologists, obstetricians, and ethicists.

    • Main Results:

    • Radiation therapy during pregnancy is associated with detrimental fetal effects, especially at doses exceeding 0.1 Gy.
    • Therapeutic abortion may be recommended in certain scenarios.
    • When radiation is unavoidable, extreme caution and fetal shielding techniques are necessary to minimize dose.

    Conclusions:

    • Decisions on radiation therapy during pregnancy must be individualized.
    • Considerations include disease prognosis, gestational stage, estimated fetal radiation dose, and patient values.
    • A multidisciplinary team approach is essential for optimal patient and fetal management.
