A 36-years-old male with mild hypertension was diagnosed with pseudocystic tumor (67 mm) in pancreatic region and liver metastasis in April 2010. One month later, the extirpation of retroperitoneal mass and metastasis was performed in local medical centre. Pathohistological diagnosis was metastatic paraganglioma (Ki67, 3.5%). In June 2010, he was transferred to our Institution, and (131) I-metaiodobenzylguanidine (MIBG) scintigraphy was negative. However ((18) F) fluorodeoxygl...

Introduction: Most patients with neuroendocrine tumors (NETs) present with liver involvement at the time of diagnosis. Trans-catheter arterial chemoembolization (TACE) is accepted treatment of patients with non-resectable hepatic metastases from NETs.Aim: To analyze objective tumor response and clinical outcome in patients with hepatic metastases from NETs who underwent TACE.Methods: Thirty-one patients underwent 140 TACE procedure...

Introduction: The coexistence of adrenal tumors (AT) in patients with neuroendocrine tumors (NETs) has not been extensively studied. The aim of our study was to investigate their prevalence and clinical significance in these patients.Materials and methods: We retrospectively studied 447 patients with NETs of all localizations, treated at our department between 2004 and 2012. Diagnosis was established pathohistologically, classification performed accordin...

Introduction: It has been shown that most women with polycystic ovary syndrome (PCOS) have increased adrenal androgen production, enhanced peripheral metabolism of cortisol and elevated in urinary excretion of its metabolites. Simultaneously, this increased cortisol clearance in PCOS was shown to be followed by a compensatory overdrive of the hypothalamo–pituitary–adrenal (HPA) axis. The aim of this study was to determine HPA axis sensitivity in women woth PCOS.<...

Introduction: Women with polycystic ovary syndrome (PCOS) are characterized with insulin resistance and hyperinsulinaemia. Adiponectin and leptin are adipose tissue-specific products and are correlated with insulin resistance. The aim of the study was to access the relation of adiponectin with anthropometric, metabolic and hormonal parameters in a group of women with PCOS.Methods: We studied 57 non-obese women with PCOS diagnosed using ESHRE/ASRM criteri...

Introduction: Generously supported by IPSEN)-->The coexistence of acromegaly and secondary polycythemia has been described in a few patients. This association was ascribed to GH/IGF1 proliferative effect on bone marrow progenitor cells. In contrast, the presence of myeloproliferative neoplasm (MPN) with documented JAK2 mutation so far has been described in only one acromegalic patient.Methods: We analyzed the p...

Introduction: Intronic BclI polymorphism of glucocorticoid receptor (GR) gene and adrenal adenomas of incidental discovery are frequently associated with metabolic syndrome. We studied in these patients metabolic and hormonal parameters, the sequence alteration in BclI polymorphism of the GR gene from constitutive DNA and the expression of Hsp70 within the tumor and in tissue adjacently to tumor.Patients and methods: We assessed 114 healthy...

Background: Several susceptibility genes have been found to be associated with development of pheochromocytoma (PHEO): RET, VHL, SDHB and SDHD. We investigate the frequency of germ-line mutations in SDHB and VHL genes in patients with apparently sporadic PHEO.Material and methods: Fifty patients (38 women, mean age 42) with apparently sporadic adrenal and extra-adrenal PHEO were screened. DNA was extracted from whole blood and from paraffin embedded tumo...

Background: Mutational screening of the MEN1 gene has been recommended for patients who fulfill clinical criteria for familial or sporadic MEN1 and those suspicious or atypical of MEN1.Patients and methods: Eighteen apparently unrelated individuals (6 males; 12 females, age range 16–71) with clinical manifestations of MEN1 were analised. In addition, we evaluated 7 relatives. Genomic DNA from peripheral blood leucocytes was extracted using st...

Several RET proto-oncogene germline mutations with dominant inheritance, predispose to hereditary medullary thyroid carcinoma (MTC), and whether the MTC is sporadic or hereditary should be determined by a direct analysis of the RET proto-oncogene. 85% of MEN IIA patients and 30% of patients with familial medullary thyroid carcinoma have mutations at codon 634 (exon 11). In 88 consecutive patients with MTC, the characterization of RET mutations in exon 11 had been done by PCR w...
