Journal ArticleDOI
A Transplantable Human Carcinoid as Model for Somatostatin Receptor-Mediated and Amine Transporter-Mediated Radionuclide Uptake
Lars Kölby,Peter Bernhardt,Håkan Ahlman,Bo Wängberg,Viktor Johanson,A. Wigander,Eva Forssell-Aronsson,Sven Karlsson,Bo Ahrén,Göran Stenman,Ola Nilsson +10 more
TL;DR: A human midgut carcinoid tumor was successfully transplanted into nude mice and propagated for five consecutive generations (30 months) with well-preserved phenotype as discussed by the authors, and the human origin of transplanted tumor cells was confirmed by cytogenetic and fluorescence it situ hybridization analyses.
Journal ArticleDOI
Uptake of meta-iodobenzylguanidine in neuroendocrine tumours is mediated by vesicular monoamine transporters.
Lars Kölby,Peter Bernhardt,A.-M. Levin-Jakobsen,Viktor Johanson,Bo Wängberg,Håkan Ahlman,Eva Forssell-Aronsson,Ola Nilsson +7 more
TL;DR: VMATs and secretory granules are of importance for the uptake and retention of 123I-MIBG in NE tumours and information about the type and degree of expression of VMATs may be helpful in future to select patients suitable for radiation therapy with radio-iodinated MIBG.
Journal Article
Internalization of indium-111 into human neuroendocrine tumor cells after incubation with indium-111-DTPA-D-Phe1-octreotide
P. Andersson,Eva Forssell-Aronsson,Viktor Johanson,Bo Wängberg,Ola Nilsson,Martha Fjälling,Håkan Ahlman +6 more
TL;DR: Indium-111 DTPA-D-Phe1-octreotide might be useful for radiation therapy of patients with surgically incurable tumors having high somatostatin receptor densities.
Journal ArticleDOI
Prognostic factors for survival after surgery for adrenal metastasis
TL;DR: Surgery for adrenal metastasis is safe and the indication for this procedure in an individual patient can be supported by several prognostic factors, and the survival benefit in patients with adrenalectomy for potential cure indicates a therapeutic value of Adrenalectomy in selected patients.
Journal ArticleDOI
The neuroendocrine phenotype, genomic profile and therapeutic sensitivity of GEPNET cell lines.
Tobias Hofving,Yvonne Arvidsson,Bilal Almobarak,Linda Inge,Roswitha Pfragner,Marta Persson,Göran Stenman,Erik Kristiansson,Viktor Johanson,Ola Nilsson +9 more
TL;DR: A large-scale inhibitor screening showed that cell lines from pancreatic NETs to a greater extent, when compared to small intestinal NETs, were sensitive to inhibitors of MEK and neuroendocrine NET cells originating from the small intestine were considerably more sensitive to a group of HDAC inhibitors.
