Summary

Surgery offers higher remission rates for prolactinomas (pituitary neuroendocrine tumours) than dopamine agonists, with fewer side effects. Early referral to specialized centers ensures optimal, individualized treatment decisions for these common pituitary tumors.

Area of Science:

  • Neuroendocrinology
  • Oncology
  • Neurosurgery

Background:

  • Prolactinomas, a type of lactotroph pituitary neuroendocrine tumor, are common and impact quality of life.
  • Dopamine agonists (DA) control prolactinomas but have low remission rates and psychiatric side effects.
  • Surgical outcomes for prolactinomas have improved with advanced techniques.

Purpose of the Study:

  • To compare the efficacy and safety of surgery versus dopamine agonists for prolactinoma treatment.
  • To evaluate the benefits of surgical remission in mitigating long-term treatment burdens.
  • To inform decision-making regarding upfront surgery versus upfront medical management.

Main Methods:

  • Comparative analysis of surgical outcomes versus dopamine agonist therapy.

  • Review of current evidence on surgical techniques for varying tumor sizes and invasiveness.
  • Discussion of multidisciplinary approaches for patient management.

    • Main Results:

    • Surgery achieves higher biochemical remission rates than DA for microadenomas and non-invasive macroadenomas.
    • Surgical remission avoids DA-related side effects, costs, and treatment anxiety.
    • Even invasive tumors may be candidates for curative resection with surgical advancements.

    Conclusions:

    • Surgery is a safe and effective option for many prolactinomas, offering superior remission rates and fewer long-term complications than DA therapy.
    • Individualized treatment decisions, weighing surgical risks against benefits, are crucial and best made at specialized pituitary tumor centers.
    • Further research is needed to identify optimal candidates for upfront surgery and the impact of preoperative DA therapy.
