[The treatment of Cushing's disease].

The differential diagnosis of Cushing's disease remains difficult to establish. The selective transsphenoidal adenomectomy is the initial treatment of choice. In a group of 65 patients, 50 (77%) initially responded to surgery with correction of their hypercortisolism. Forty-three out of 51 (84%) patients with small pituitary tumors responded favourably to surgery, but recurrency occurred in 10% of the cases. Medical treatment with steroids inhibitors or antagonists is only an adjuvant treatment. In case of surgery failure or recurrency, bilateral adrenalectomy is usually performed. Conventional radiotherapy may be used after surgery in presence of macroadenomas or invasive adenomas. Correction of the hypercortisolism, after a second surgery, was achieved in 50% of the cases and was always associated with a panhypopituitarism.

[The treatment of acromegaly].

Acromegaly is a rare disease which can significantly reduce life expectancy. Clinical features are diverse and the patient may consult a variety of medical and surgical specialists before the diagnosis is suspected. However, the disease is easily confirmed by the appropriate laboratory tests, namely GH and IGF1 measurements. In most cases, acromegaly is secondary to a micro or macrosomatotrope pituitary adenoma. Those lesions are easily visualized by a pituitary CT Scan or Magnetic Resonance Imaging. Visual fields have to be evaluated by a neuro-ophthalmologist, and a thorough evaluation of other pituitary functions have to be performed. Selective removal of the adenoma by the transsphenoidal route is the treatment of choice for acromegaly. When performed by an experienced neurosurgeon, normalization of GH secretion can be expected in approximately 75% of cases. The surgical outcome is modulated by the volume, the extension of the tumor and the preoperative GH level. Octreotide, radiotherapy or bromocriptine are indicated whenever the patient remains with an elevated level of GH with persistency of symptoms.
