Cervical lymph node metastasis in differentiated thyroid carcinoma: does it have an impact on disease-related morbid events?

Purpose: The aim of the study was to evaluate the prognostic impact of cervical lymph node (CLN) metastasis in well-differentiated thyroid cancer (WDTC).

Patients And Methods: A cohort of 164 patients who underwent thyroidectomy for WDTC in the last 12 years was studied. Patients were classified into those with CLN metastasis (group 1) and those without (group 2), with 82 patients in each group.

Patients with end-stage renal disease: optimal diagnostic and prognostic performance of myocardial gated-SPECT, initial results.

Purpose: We investigated the role of Tc-99m sestamibi myocardial perfusion gated single photon emission computed tomography (GSPECT) in identifying those patients with end-stage renal disease (ESRD) in whom optimal diagnosis of coronary artery disease and prediction of cardiac events (CEs) could be achieved.

Methods: This was a prospective study that included 41 asymptomatic ESRD patients who had been undergoing hemodialysis for 12 months or less (22 men and 19 women) with restricted selection criteria (asymptomatic traditional risk). Tc-99m sestamibi GSPECT was carried out for all patients, whereas coronary angiography (Cath) was carried out only for abnormal GSPECT patients, with a 2-year follow-up for CEs.
