PURPOSE: The guidelines for management of prolactinomas during pregnancy are mostly based on retrospective evidence or expert opinion. We conducted a survey to assess the current trends in management of prolactinomas during pregnancy.
METHODS: A case-based electronic questionnaire was sent in January 2011 to all practicing endocrinologists, in four Canadian provinces: Nova Scotia, New Brunswick, Prince Edward Island and British Columbia with three cases of varying severity; ranging from a microprolactinomas to a large macroprolactinomas compressing the optic chiasm.
RESULT: There was a considerable diversity among endocrinologists with regards to monitoring and managing prolactinomas during pregnancy. In case of microprolactinomas, 94% of specialists would discontinue dopamine agonist (DA) therapy upon confirmation of pregnancy, 79% would discontinue serum prolactin measurement during pregnancy, and 94% would not perform routine pituitary imaging in the absence of new symptoms whereas 32% would perform regular formal visual field (VF) testing throughout pregnancy. In the case of macroprolactinomas, 65% chose to discontinue DA therapy upon confirmation of pregnancy, 30% would either perform regular MRI during pregnancy or, if serum prolactin was thought to be elevated out of proportion, with clinical judgment and 40% would not perform regular formal VF monitoring during pregnancy. In management of large macroprolactinomas, 82% elected to continue DA therapy whereas 18% chose surgical excision as the treatment of choice. Forty nine percent would perform regular MRI during pregnancy and 94% would perform regular formal VF monitoring during pregnancy.
CONCLUSION: Among endocrinologists there is considerable diversity in management of prolactinomas during pregnancy, indicating a need for better consensus and clearer guidelines.
