Prognostic factors and staging systems in parathyroid cancer: a multicenter cohort study.

Background: Parathyroid carcinoma (PC) is an uncommon disease that generally is detected postoperatively and traditionally is associated with a poor prognosis. Our purpose was to evaluate treatment outcomes, prognostic factors, and usefulness of some proposed staging systems for this disease.

Methods: A multicenter review of patients with surgically resected PC was performed, led by the Spanish Association of Surgery.

[Primary hyperparathyroidism and acute toxic hypercalcaemic crisis].

Objectives: To describe the clinical characteristics and surgical treatment of patients with acute hypercalcaemia due to primary hyperparathyroidism (PHPT) and compare them with other patients with PHPT without associated acute hypercalcaemia.

Material And Methods: A prospective, observational study (1998-2010) was conducted on 158 patients with PHPT treated by parathyroidectomy. Those with acute hypercalcaemia (>14 mg/dl -3.

Objectives: 1. To assess the sensitivity of scintigraphy using methoxy isobutyl isonitrile (MIBI). 2.

[Development and outcomes of the surgical management of multinodular goiter].

Objectives: The aims of this study were to: 1. Define our criteria and the results obtained in the surgical management of multinodular goiter (MNG); 2. Compare the results of partial thyroidectomies with those of total thyroidectomies; 3.
