Incidence of metastatic well-differentiated thyroid cancer in cervical lymph nodes.

Objective: To determine the incidence of clinically positive lateral cervical nodes at presentation and after initial treatment in patients with well-differentiated thyroid cancer.

Design: Retrospective chart review.

Setting: University-affiliated teaching hospitals.

Sestamibi scans and intraoperative parathyroid hormone measurement in the treatment of primary hyperparathyroidism.

Objective: To assess the value of preoperative sestamibi scanning and intraoperative parathyroid hormone (IOPTH) measurement in the treatment of patients with primary hyperparathyroidism due to multiple gland disease (MGD).

Design: Retrospective medical record review.

Setting: Tertiary care academic medical center.

The value of frozen section examinations in determining the extent of thyroid surgery in patients with indeterminate fine-needle aspiration cytology.

Objectives: To determine the usefulness of intraoperative frozen section (FS) examinations in establishing the diagnosis of thyroid cancer in patients undergoing thyroidectomy for nodules with indeterminate cytological features and to determine the cost-effectiveness of FS examinations in this situation.

Design: Retrospective medical record review. The results of fine-needle aspiration biopsies (FNABs), FS examinations, and final pathologic examinations are compared.
