[A Scandinavian multicenter study will investigate the question: surgery or not in mild primary hyperparathyroidism?]

Primary hyperparathyroidism is a common endocrine disease particularly prevalent among elderly women. A majority of these patients diagnosed today are mildly hypercalcaemic, and many seem to lack manifest symptoms or complications. In such cases, conservative follow-up rather than parathyroid surgery may be suggested. However, long-term follow-up may entail costly investigations and be difficult to accomplish. Moreover, conservative follow-up is associated with a risk of subsequent complications or even premature death due to cardiovascular disorders. A Scandinavian multicentre study has been initiated to assess survival, morbidity and quality of life in surgically vs. conservatively treated patients.
