68Ga-BBN-RGD PET/CT for GRPR and Integrin αvβ3 Imaging in Patients with Breast Cancer
Purpose: This study was to assess a gastrin-releasing peptide receptor (GRPR) and integrin αvβ3 dual targeting tracer 68Ga-BBN-RGD for positron emission tomography (PET)/computed tomography (CT) imaging of breast cancer and metastasis. Materials and Methods: Twenty-two female patients were recruited either with suspected breast cancer on screening mammography (n = 16) or underwent breast cancer...
متن کاملA new cyclic RGD peptide dimer for integrin αvβ3 imaging.
OBJECTIVE To design a new Arg-Gly-Asp (RGD) peptide that can specifically bind integrin αvβ3 and evaluate the possibility of using 131I-labeled peptide for imaging αvβ3-positive tumors. MATERIALS AND METHODS The structure of the RGD monomer was selected using V-life software. Based on the RGD monomer, a dimer of cyclic RGD [c(RGD)2] linked by Tyr-(D)Ser-Lys-(D)Ser-Ser with a Gly-Gly-(D)Ala-Gl...
متن کاملComplementary, Selective PET Imaging of Integrin Subtypes α5β1 and αvβ3 Using 68Ga-Aquibeprin and 68Ga-Avebetrin.
UNLABELLED Despite in vivo mapping of integrin αvβ3 expression being thoroughly investigated in recent years, its clinical value is still not well defined. For imaging of angiogenesis, the integrin subtype α5β1 appears to be a promising target, for which purpose we designed the PET radiopharmaceutical (68)Ga-aquibeprin. METHODS (68)Ga-aquibeprin was obtained by click-chemistry (CuAAC) trimeri...
متن کاملGastrin-releasing Peptide Receptor Imaging in Breast Cancer Using the Receptor Antagonist 68Ga-RM2 And PET
INTRODUCTION The gastrin-releasing peptide receptor (GRPR) is overexpressed in breast cancer. The present study evaluates GRPR imaging as a novel imaging modality in breast cancer by employing positron emission tomography (PET) and the GRPR antagonist (68)Ga-RM2. METHODS Fifteen female patients with biopsy confirmed primary breast carcinoma (3 bilateral tumors; median clinical stage IIB) unde...
متن کاملClinical Application of Radiolabeled RGD Peptides for PET Imaging of Integrin αvβ3
Molecular imaging for non-invasive assessment of angiogenesisis is of great interest for clinicians because of the wide-spread application of anti-angiogenic cancer therapeutics. Besides, many other interventions that involve the change of blood vessel/tumor microenvironment would also benefit from such imaging strategies. Of the imaging techniques that target angiogenesis, radiolabeled Arg-Gly...
