Thyroid cancer is one of the most rapidly increasing cancer diagnoses worldwide. Thyroid cancers exhibit the full range of cancer behavior from the relatively indolent occult papillary thyroid cancer to the uniformly aggressive and lethal undifferentiated thyroid cancers. Surgical resection is the principal treatment for thyroid cancer and there are several important areas of controversy in the surgical management of thyroid cancer. Some of these controversies have arisen due ...

Background: Biochemical biomarker DT is used clinically for prognosis prediction in several solid malignancies. The aim of the current analysis was to determine whether biomarker DT has any prognostic utility in patients with NETs.Methods: Patients with NETs (n=184) were enrolled in a prospective study with comprehensive biochemical analysis. The current analysis included subjects with increasing 5-HIAA levels in at least two consecutive measure...

Introduction: Familial non-medullary thyroid cancer(FNMTC) represents 3–9% of thyroid cancer cases. Although the susceptibility genes for syndromic FNMTC are known, most cases of FNMTC are nonsyndromic and the genetic causes are unknown.Patients and methods: We conducted a multicenter study to identify a candidate susceptibility gene for nonsyndromic FNTMC. We collected blood specimens, clinical and pathological data from 38 kindreds with FNMTC (32 ...

Background: About 8–20% of patients with von Hippel-Lindau disease (vHLd) develop pancreatic neuroendocrine tumors (PNETs). However, prognostic markers for these tumors are lacking. The VHL gene mutation type is associated with the clinical phenotype of vHLd. Hence, we aimed to determine whether VHL mutation characteristics may be associated with PNETs phenotype in patients with vHLd.Methods: A prospective study of patients with vHLd and PNETs with ...

Background: Patients with neuroendocrine tumors (NETs) have divergent survival, even when having the same site of primary tumor, and tumor stage and grade. 68Gallium (68Ga)-DOTATATE positron emission tomography (PET)/computed tomography (CT) is a sensitive imaging modality for detecting NETs. The purpose of this study was to determine whether 68Ga-DOTATATE PET/CT imaging has any prognostic utility in patients with NETs.Methods: One hundred and eighty-fou...

Introduction: Germline inactivating mutations of the protein kinase A (PKA) regulatory subunit RIα (the PRKAR1A gene) cause primary pigmented nodular adrenocortical disease (PPNAD); other cyclic AMP (cAMP) signalling defects have been associated with bilateral adrenocortical hyperplasia (BAH), cortisol-producing adenoma (CPA) and related lesions. Recently, PRKACA somatic mutations were detected in single, sporadic CPAs in approximately 40% of patients wi...
