Shared Care Planning for a pregnant patient with uveal melanoma treated with interventional radiotherapy (brachytherapy)

Introduction: Uveal melanoma (UM) is the most prevalent primary intraocular tumor in adulthood, with an important risk of metastasis, notably to the liver, rendering standard chemotherapy ineffective. Cases of UM onset during pregnancy are rare but can exhibit accelerated tumor growth. For these cases the best conservative treatment is interventional radiotherapy (IRT) also known as brachytherapy (BT). It is a form of radiotherapy that demonstrates efficacy comparable to the more common enucleation, while mitigating any risks of intrauterine toxicity. Objective: We reported the case of M., a 39-year-old pregnant patient, diagnosed with UM and undergoing brachytherapy treatment. Our aim is to make pertinent ethical considerations about: a. The ethical and clinical approach favouring a treatment strategy that preserves the affected organ and its functionality, b. The advance care planning process conducted within a multidisciplinary team. Case discussion: With the objective of preserving the mother’s health and ensuring the protection of the foetus, the team unanimously agreed, through a collaborative decision-making process, to proceed with the viable brachytherapy intervention. This approach results in a lower burden and maximizes benefits for both the patient and the unborn child. Conclusions: Considering a holistic evaluation, especially considering the patient’s pregnancy, the multidisciplinary approach proves fundamental. Collaboration between bioethicists and health-care professionals facilitated the development of a shared document for healthcare ethics planning, expressing the team’s ethical-clinical considerations.
