Insights
Effective acromegaly treatment normalizes mortality by normalizing growth hormone (GH) and IGF-1 levels. Combining therapies like somatostatin analogs (SA) with pegvisomant (PEG-V) or cabergoline may improve outcomes.
Area of Science:
- Endocrinology
- Oncology
Background:
- Acromegaly is a rare, disabling disease with high cardiovascular mortality.
- Mortality risk is reduced to normal levels when GH and IGF-1 levels are normalized through treatment.
Purpose of the Study:
- To review current therapeutic strategies for acromegaly control.
- To explore combination therapies and surgical debulking for optimizing treatment outcomes.
Main Methods:
- Review of epidemiological evidence and current therapeutic approaches for acromegaly.
- Analysis of the efficacy of somatostatin analogs (SA), dopamine agonists (DA), and pegvisomant (PEG-V).
Main Results:
- Somatostatin analogs (SA) control acromegaly in about two-thirds of patients.
- Combination therapy (SA with PEG-V or DA) and surgical debulking show potential for enhanced control and overcoming resistance.
Conclusions:
- Optimizing acromegaly control can be achieved through combination therapies and adjunct surgical debulking.
- These strategies may improve patient outcomes and potentially reduce healthcare costs.
Abstract:
Acromegaly is a rare chronic and disabling disease with many comorbidities leading to a mortality rate three times higher than in the normal population, mainly due to cardiovascular diseases. Based on epidemiological evidence, the mortality rate is normalized to normal population values when treatment brings serum GH levels to <2.5 microg/l and IGF-1 levels to normal age/gender values. Many efficacious therapeutic approaches are currently available to acromegaly control, namely pituitary surgery, radiotherapy and medical therapy, which encompasses dopamine agonists (DA), somatostatin analogs (SA; currently considered the gold standard treatment) and the GH-receptor antagonist pegvisomant (PEG-V). The efficacy and indications of each therapy depend on the tumor size and invasiveness, patient's condition and the local availability of each treatment modality. Treatment with SA analogs controls about two thirds of acromegalics, with recent data highly suggesting that this result can be enhanced by the combination of SA with PEG-V, or with the DA cabergoline. Moreover, surgical tumor debulking, even noncurative, might overcome the resistance of GH-secreting adenomas to SA. Therefore, these strategies may optimize acromegaly control, and potentially reduce treatment costs.
