Review of Cortina criteria for the diagnosis of acromegaly.

Diagnostic protocols for acromegaly have evolved over time reflecting the refinement of assays for the biochemical assessment of the GH-IGF-I axis and greater understanding of disease process. In February 1999, an International Consensus Conference was held in Cortina, Italy, to define the criteria for cure of acromegaly. This review paper summarizes the diagnostic guidelines proposed in the consensus statement by Giustina et al. In recent years, however, the criteria for both biochemical assessment and long-term monitoring in patients with acromegaly have changed with the development of increasingly sensitive and specific GH assays coupled with the widespread availability of reliable IGF-I assays. For this reason, constant updating of the assessment criteria proposed in the workshop held in Cortina, in 1999, would be advisable.
