<prompt> Traetment of prolactinoma 7 mm in diameter is?Transsphenoidal resectionDopamine agonistsStereotactic radiosurgeryFractionated stereotactic radiotherapy  <response>: Treatment of Pituitary Tumors Dopamine agonist, bromocriptine, can shrink prolactinomas in 75 of patients with macro adenomas in 6-8 weeks, but only as long as therapy is maintained Bromocriptine may also work on GH-secreting tumors with tumor shrinkage in 20 Octreotide can reduce GH levels in 71 of patients, with significant reduction in tumor volume in 30 cases Indications of surgery as an Initial Treatment GH-secreting tumors Primary Cushings disease Any adenoma causing acute visual deterioration Non prolactin - secreting macro adenomas causing by mass effect Surgical approach of choice : Sublabial or intranasal trans-sphenoidal approach Recurrence rate : 12 most recurrences occur 4-8 years after surgery Radiosurgery can also be used either as primary therapy, as an adjuvant therapy after subtotal resection, or for recurrent disease. Main dose-limiting structure is proximity to the optic chiasma optic nerves within 3-5 mm. In this case, Fractionated EB may be indicated as an adjuvant therapy Ref : Sabiston 20th edition Pgno : 1914
