Selective transsphenoidal adenomectomy is generally recommended for initial treatment of Cushing's disease (CD) because it achieves a high (70-85%) rate of remission. However, if initial surgery is not successful, the approach to persistent or recurrent CD is more complex. Because residual or recurrent adenoma is typically found at the site of the original adenoma, repeat transsphenoidal surgery is recommended including selective adenomectomy, hemihypophysectomy or total hypophysectomy. If repeat pituitary surgery does not achieve remission, then possible adjuvant therapies include radiosurgery or stereotactic radiotherapy, bilateral adrenalectomy, and/or medical therapy. In all cases of persistent or recurrent CD, successful treatment requires close collaboration of endocrinologists, radiation oncologists and neurosurgeons.

Résumé:

Résumé:

L'adénomectomie transsphénoïale est généralement recommandée comme traitement initial de la maladie de Cushing (MC) parce que le taux de rémission obtenu est élevé, de l'ordre de 70% à 85%. Cependant, si la chirurgie initiale est un échec, la conduite à tenir en cas de persistance ou de récidive de la MC est plus complexe. Étant donné que, de façon typique, l'adénome résiduel ou récidivant est situé a l'endroit où était situé l'adénome initial, une nouvelle chirurgie transsphénoïale est recommandée, avec adénomectomie sélective, hémihypophysectomie ou hypophysectomie totale. Si une réintervention à l'hypophyse n'entraîne pas de rémission, des traitements adjuvants dont la radiochirurgie ou la radiothérapie stéréotaxique, la surrénalectomie bilatérale et/ou le traitement médical sont des options à considérer. Chez tous les cas de MC persistante ou récidivante, le succès du traitement dépend d'une collaboration étroite entre endocrinologues, radio-oncologues et neurochirurgiens.
