  1. 1. Pharmacokinetics and dosimetry of radiolabelled octreotide for tumour therapy

    Författare :Peter Bernhardt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacokinetics; radiation dosimetry; therapy; radionuclides; octreotide; neuroendocrine tumours; nude mice; patients;

    Sammanfattning : Somatostatin (SS) receptors (sstr) are usually highly expressed on neuroendocrine (NE) tumours. The radiolabelled SS analogue 111In-DTPA-D-Phe1-octreotide is today widely used to scintigraphically visualise NE tumours, and high 111In activity concentrations are obtained in tumour vs. normal tissues.

  3. 2. Labelling of various macromolecules using positron emitting 76Br and 68Ga : Synthesis and characterisation

    Författare :Ulrika Yngve; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; 76Br; Radiobromination; Prosthetic Groups; Macromolecules; Oligonucleotides; 68Ga; PET; Octreotide; Metal Chelates; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : Different prosthetic groups containing a trialkylstannyl- and an electrophilic group have been synthesised and labelled with the accelerator produced 76Br (T1/2=16 h) through oxidative bromination. The labelled prosthetic groups were conjugated to amino-containing macromolecules such as proteins and 5´-modified oligonucleotides. LÄS MER

  4. 3. 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

  5. 4. Midgut carcinoid tumours - biochemical and therapeutic aspects

    Författare :Gunnel Westberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carcinoid syndrome; valvular heart disease; 5-HT; chromogranins; octreotide; hepatic arterial embolization;

    Sammanfattning : The biology of human midgut carcinoid tumour was studied experimentally in primary cell culture and clinically in patients with the midgut carcinoid syndrome. In cell cultures, tumour cells had a secretory pattern of 5-HTP, 5-HT and 5-HIAA specific for each tumour indicating individual regulation of synthesis/degradation. LÄS MER

  7. 5. Aspects on Diagnosis and Treatment of Gastrointestinal Neuroendocrine Tumours

    Författare :Christina Swärd; Göteborgs universitet; []
    Nyckelord :Carcinoid; Endocrine pancreatic tumour; Neuroendocrine; Octreotide; Somatostatin receptor; Peptide receptor; Radionuclide therapy; Absorbed dose; Chromogranin A; Liver transplantation;

    Sammanfattning : Aspects on Diagnosis and Treatment of Gastrointestinal Neuroendocrine Tumours Background. Gastroenteropancreatic neuroendocrine tumours (GEP-NETs) originate from endocrine cells of the intestinal mucosa and pancreas. LÄS MER
