Diagnosis

The approach to diagnosis of Acromegaly is based on a step-wise testing strategy. Below is an algorithm summarising the identification and laboratory diagnosis of Acromegaly.

Characterize the symptoms: ❑ Headaches ❑ Enlargement of the hands (change in ring or glove size) and feet (change in shoe size) ❑ Lethargy ❑ Hyperhidrosis (excessive sweating) ❑ Paraesthesia ❑ Sexual dysfunction ❑ Fatigue ❑ Jaw pain ❑ Body odor ❑ Blood in the stool ❑ Sleep apnea ❑ Weight gain

Examine the patient: ❑ HEENT Changes in facial appearance (large bones of the face, large jaw and tongue, widely spaced teeth) Visual disturbance Hoarseness of voice Enlargement of thyroid gland ❑ Musculoskeletal exam: Joint pain Limited joint movement Swelling of the bony areas around a joint Carpal tunnel syndrome ❑ Neurological exam: Decreased muscle strength and power (Muscle weakness) ❑ Cardiovascular exam: High blood pressure

Treatment

Shown below is an algorithm summarizing the treatment of [[Acromegaly]] according the the [...] guidelines.

Acromegaly

Transphenoidal surgery ❑ Complete resection ❑ Tumors that are unresectable, a surgical debulking procedure may be performed followed by medical therapy

Yes

Patient is not a surgical candidate ❑ Patient preference ❑ High risk due to medical comorbidities ❑ Unresectable tumors

Are the following criteria met postoperatively? ❑ Morning serum GH the day after surgery <1ng/ml ❑ 12 weeks postoperative: Normal serum IGF-1 (for age and gender) No evidence of residual tumor on pituitary MRI

Yes

No

Remission ❑ Monitor with annual IGF-1

Is there residual tumor that appears resectable and readily accessible (eg, not invading the cavernous sinus)?

Perform MRI for clinical or biochemical evidence of recurrence

Medical therapy

Failure of medical therapy

Radiation therapy ❑ Stereotactic radiotherapy is most common method
