A patient with anaplastic meningioma and lung metastases resistant to conventional treatment underwent radiopeptide therapy with 177Lu- DOTA-octreotate in our institute. The treatment resulted in significant improvement in patient's quality of life and inhibition of tumor progression. This case may eventually help to establish the value of radiopeptide therapy in patients with this rare condition.
BACKGROUND As model system, a solid-tumor patient-derived xenograft (PDX) model characterized by high peptide receptor expression and histological tissue homogeneity was used to study radiopeptide targeting. In this solid-tumor model, high tumor uptake of targeting peptides was expected. However, in vivo SPECT images showed substantial heterogeneous radioactivity accumulation despite homogenous...
introduction: a noninvasive method of detecting exposure of phosphatidylserine (ps) on the external surface of the plasma membrane such as nuclear imaging could assist the diagnosis and therapy of apoptosis related pathologies. the most studied imaging agent for apoptosis is annexin v so far. because of limitations of annexin v other agents have been introduced such as small peptides and molecu...
melanocortin-1 (mc1) receptor is an attractive melanoma-specific target for the development of α-msh peptide based imaging and therapeutic agents. in this work a new lactam bridge α-msh analogue was synthesized and radiolabeled with 99mtc via hynic chelator and tricine as co-ligand. also, stability in human serum, receptor bound internalization and tissue biodistribution in tumor bearing nude m...
BACKGROUND Neuroendocrine tumors are well vascularized and express specific cell surface markers, such as somatostatin receptors and the glucagon-like peptide-1 receptor (GLP-1R). Using the Rip1Tag2 transgenic mouse model of pancreatic neuroendocrine tumors (pNET), we have investigated the potential benefit of a combination of anti-angiogenic treatment with targeted internal radiotherapy. MET...
