PRolaCT - Three Prolactinoma RCTs

"Neurosurgical consultation consists of at least one consult with a neurosurgeon and at least one consult with an endocrinologist with relevant experience. If the multidisciplinary team (MDT) agrees the patient is a good surgical candidate, the patient is asked consent for surgery, as is a custom part of preoperative requirements. When the patient decides not to have the surgery, (s)he will receive standard medical treatment, but will continue study follow up in the intervention group.~Surgery only takes place if both the MDT and the patient agree to it and should then be planned within three months after randomization. Surgery is performed by one or two trained neurosurgeons in the hospital where the counseling took place. A standard, semi-protocolled, endoscopic trans-sphenoidal surgical resection of the prolactinoma is performed according to standard practice."

"The treating physician adheres to the treatment protocol in general, but has freedom to choose treatment to his/her ideas how to deliver best care.~Current first line treatment consists of a dopamine agonists: cabergoline (currently the most used), bromocriptine or quinagolide. All dopamine agonists are taken orally, and the dosage may be raised based on its effect. It is usually titrated to achieve a normal or suppressed prolactin level and restoration of the gonadal axis. Dopamine agonist treatment is discontinued after 2 years of treatment, unless a normal prolactin level cannot be achieved. The dopamine agonist is restarted when prolactin levels rise after the medication is discontinued.~In standard care, surgical treatment is reserved for patients who don't tolerate medication, or whose adenoma fails to show a sufficient response. Patients in the control group with an intolerance for dopamine agonists or an insufficient response may be offered surgery as part of standard care."
