Presence of clinical symptoms and signs specific for suspected illness is, in general, a condition sine qua non to start diagnostics procedures. However, some diseases may proceed with various and disparate symptoms, which often suggests completely different diagnosis. One of them is pheochromocytoma – rare, usually benign neoplasm derived from chromaffin cells of adrenal medulla. It is very important to diagnose the disease while it is curable by surgery like ma...

Adrenal cortex scintigraphy has been used as early as in the 1970s, however, in recent years, it has been a rarely performed and unappreciated examination. In fact, this examination does not provide a perfect view on morphology of adrenal glands, however it provides an assessment of the examined tumor’s function. The aim of this work is to present our experience with adrenal cortex scintigraphy in assessment of adrenal tumors.We present a series of ...

Objective: According to some authors a higher incidence of subclinical hypercortisolaemia is found among patients with bilateral adrenal tumors with benign phenotype than with unilateral ones. The question is whether all patients with bilateral adrenal tumors and subclinical hypercortisolemia should undergo surgery and, if yes, which of the tumors should be removed first.Patients and methods: The investigated group consisted of 25 patients with benign bi...

Introduction: Ultrasound imagining of parathyroid lesions is often challenging, as they may be difficult to distinguish from thyroid lesions or enlarged lymph nodes.Aim: The aim of the study was to assess the value of parathyroid hormone determination in ultrasound-guided fine-needle aspirates-(FNA) in preoperative localization of parathyroid lesions.Materials and methods: We measured FNA–PTH in 30 consecutive patients with pr...

Background: MEN1 is an autosomal dominant inherited syndrome. Primary hyperparathyroidism, tumors of the endocrine pancreas, and of the pituitary, are the characteristic features of the syndrome.Objective: To present a case of MEN1 in a patient with extreme obesity, causing serious difficulties in diagnostic procedures leading to localization of pancreatic tumors.Case presentation: 22-year-old male with extreme obesity (BMI 59), hy...

Background: There are no effective blood biomarkers for bronchopulmonary carcinoids (BPC). We examined the utility of a neuroendocrine multigene transcript ‘liquid biopsy’ (NETest) in bronchopulmonary carcinoids (BPC) for diagnosis and monitoring of disease status.Aim: To independently validate the utility of the NETest in diagnosis and management of BPC in a prospective multicenter, multinational blinded study.Material a...

Introduction: Data demonstrating antiproliferative effects of somatostatin analogs (SSAs) in enteropancreatic NETs are limited; only one prospective trial so far has shown this for patients with midgut tumors and low hepatic tumor load (HTL). CLARINET is the first large phase 3, randomized, placebo-controlled trial evaluating such effects for the SSA lanreotide in patients with non-functioning enteropancreatic NETs.Methods: Patients who had well/moderate...

Objective: Incidentally found adrenal tumour (adrenal incidentaloma = AI) is the most frequent adrenal disorder. Every patient with AI has to be evaluated carefully to choose the best method of management. We present our experience with a group of 1300 patients with AI, registered at our department.Material and methods: Material consisted of 1300 patients (female/male ratio 2.6, age 10–87 years) with AI ranging in size from 0.8 to 23.0 cm. Methods: ...

Background: The efficacy of PRRT is based upon NET over expression of somatostatin receptor (SSR) to deliver targeted isotope therapy. SSR expression (Krenning scale) compared to Predictive Quotient Index (PQI) (circulating NET transcript analysis mathematically integrated with grade) indicates the latter is more accurate for predicting PRRT efficacy. We evaluated whether PQI was specifically predictive or was prognostic for PRRT compared to other therapeutic strategi...

Background: There is currently no effective blood biomarker for lung neuroendocrine neoplasia diagnosis and management. We describe the clinical utility of a 51 neuroendocrine-specific gene expression set in blood to diagnose bronchopulmonary neuroendocrine tumors (BPNETs) and define their clinical status.Methods: The discovery set included BPNETs (n=154) and controls (n=90), randomly assigned (1:1) to a test and validation set. Specifi...
