1. 1. Molecular studies of endocrine tumors : Insights from genetics and epigenetics

   Författare :Samuel Backman; Per Hellman; Peter Stålberg; Olov Norlén; Robert Bränström; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuroendocrine tumors; Carcinoid; Pheochromocytoma; Aldosterone; Cancer; MEN1; Multiple endocrine neoplasia; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Endocrine tumors may be benign or malignant and may occur in any of the hormone producing tissues. They share several biological characteristics, including a low mutation-burden, and may co-occur in several hereditary tumor syndromes. The aim of this thesis was to identify genetic and epigenetic aberrations in endocrine tumors. LÄS MER

3. 2. Genetic studies of endocrine abdominal tumors

   Författare :Ola Hessman; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; MEN1; LOH; pancreatic endocrine tumors; midgut carcinoid; Smad4 DPC4; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Sammanfattning : Pancreatic endocrine tumors (PETs) occur sporadically or in the familial multiple endocrine neoplasia type 1 (MEN1) syndrome, whereas midgut carcinoids are nonfamilial, malignant endocrine tumors of the intestine. For these tumor entities morphological criteria are of limited use for prognostic prediction and selection of treatment. LÄS MER

4. 3. Genetic Aspects of Endocrine Tumorigenesis : A Hunt for the Endocrine Neoplasia Gene

   Författare :Alberto Delgado Verdugo; Peyman Björklund; gunnar westin; Per Hellman; Filip Farnebo; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exome sequencing; SDHAF2; epigenetics; methylation; methylation array; Sanger sequencing; pheochromocytoma; SI-NETs; carcinoid; oncology; endocrine surgery; parathyroid; Genetics; Genetik; Kirurgi; Surgery;

   Sammanfattning : Endocrine tumors arise from endocrine glands. Most endocrine tumors are benign but malignant variants exist. Several endocrine neoplasms display loss of parts of chromosome 11 or 18, produce hormones and responds poorly to conventional chemotherapeutics. The multiple endocrine neoplasia syndromes are mainly confined to endocrine tumors. LÄS MER

5. 4. Intraoperative scintigraphic detection of abdominal endocrine tumors : Development and evaluation of hand held gamma sensitive probes for¹¹¹In

   Författare :Ulf Öhrvall; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Adrenocortical carcinoma; endocrine pancreatic tumors; mid-gut carcinoids; intraoperative gammadetection; octreotide; scintigraphy; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Sammanfattning : Surgery of endocrine tumors benefit from accurate pre and- intraoperative localization methods,and scintigraphy has become an important contribution in this respect. In the present thesis therequisites for scintigraphic localization of abdominal endocrine tumors and new detectors forintraoperative gammadetection are evaluated. LÄS MER

7. 5. Pancreatic Endocrine Tumors and GIST - Clinical Markers, Epidemiology and Treatment

   Författare :Sara Ekeblad; Britt Skogseid; Peter Stålberg; Barbro Eriksson; Rajesh Thakker; Uppsala universitet; []
   Nyckelord :Medicine; Pancreatic endocrine tumor; Gastrointestinal stromal tumor; Neuroendocrine; Multiple endocrine neoplasia type 1; Prognostic factors; Temozolomide; TNM staging; O6-methylguanine DNA methyltransferase; Growth hormone secretagogue receptor; Ghrelin; Medicin;

   Sammanfattning : Pancreatic endocrine tumors and gastrointestinal stromal tumors are rare. Evidence regarding prognostic factors, and in the former also treatment, is scarce. We evaluated the survival and prognostic factors in a consecutive series of 324 patients with pancreatic endocrine tumors treated at a single institution. LÄS MER
