This study was undertaken to evaluate the renal radioactivity levels of a newly designed 67Ga-labeled antibody fragment with a linkage cleaved by enzymes present on the brush border membrane (BBM) lining the lumen of the renal tubule. EXPERIMENTAL DESIGN: 67Ga-labeled S-2-(4-isothiocyanatobenzyl)-1,4,7-triazacyclononane-1,4,7-triacetic acid (SCN-Bn-NOTA) was conjugated with an antibody Fab fragment through a Met-Val-Lys linkage (67Ga-NOTA-MVK-Fab) considering that a Met-Val sequence is a substrate of enzymes on the renal BBM and 67Ga-NOTA-Met is excreted from the kidney into the urine. The enzymatic recognition of the...

ConclusionThe specificity, overall accuracy, and PPV of whole-body DWIBS are significantly lower than those of18F-FDG PET/CT because of a high incidence of false-positive findings particularly for detecting bone metastasis, whereas whole-body DWIBS shows a similar level of sensitivities for detecting lymph node and bone metastases to those of18F-FDG PET/CT. DWIBS should be carefully used for cancer staging in children because of its high incidence of false-positive findings in skeletons.

A 39-year-old woman with papillary thyroid cancer underwent 131I therapy after thyroidectomy. Posttherapeutic 131I whole-body scan accidentally showed symmetric “hot spots” in the pelvic region beyond known bone metastases. SPECT/CT was immediately added and revealed metal artifacts with 131I accumulation in the nearby uterus. Further inquiry discovered that she underwent tubal ligation 19 years ago. Our case demonstrates that 131I accumulation can occur at the site of oviducts many years after tubal ligation, which should be distinguished from 131I-avid metastases.

In this study, we prepared multifunctional microspheres from 131I-labeled hollow copper sulfide nanoparticles loaded with paclitaxel (131I-HCuSNPs-MS-PTX) for imaging and therapeutics of W256/B breast tumors in rats. 18F-fluordeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) imaging detected that the expansion of the tumor volume was delayed (P<0.05) following intra-tumoral (i.t.) injection with 131I-HCuSNPs-MS-PTX plus near-infrared (NIR) irradiation. The immunohistochemical analysis further confirmed the anti-tumor effect. The single photon emission computed tomography (SPECT)/photoacous...

CONCLUSION: Residual nodal metastasis following initial surgical treatment for regionally advanced differentiated thyroid cancer is rather common on highly sensitive 131-I scans with SPECT/CT and is due to both unrecognized nodal involvement preoperatively and incomplete removal of metastatic lymph nodes during compartment-orientated nodal dissection. The surgical management of high-risk DTC should include preoperative imaging to evaluate for nodal metastases in the central and lateral neck and compartment-orientated nodal dissection of involved compartments. Attention should be given to complete dissection in levels VI, I...

AbstractPurposeThe gastrin-releasing peptide receptor (GRPR), overexpressed on various tumor types, is an attractive target for receptor-mediated imaging and therapy. Another interesting approach would be the use of GRPR radioligands for pre-operative imaging and subsequent radio-guided surgery, with the goal to improve surgical outcome. GRPR radioligands were successfully implemented in clinical studies, especially Sarabesin 3 (SB3) is an appealing GRPR antagonist with high receptor affinity. Gallium-68 labeled SB3 has goodin vivo stability, after labeling with Indium-111; however, the molecule shows poorin vivo stability...

Authors: Liu C, Gong Q, Chen T, Lv J, Feng Z, Liu P, Deng Z Abstract Multidrug resistance (MDR) is an obstacle for cancer chemotherapy. It was reported that 20(S)-ginsenoside Rg3 (hereafter Rg3) was able to regulate MDR in mouse leukemia cells. The present study investigated the effect of Rg3 on the MDR of A549 lung cancer cells. A cell viability assay revealed that Rg3 treatment increased cisplatin (DDP) cytotoxicity in DDP resistant A549 cells (A549/DDP). Furthermore, Rg3 increases the antitumor effect of DDP on A549/DDP xenograft mice. The expression of MDR-mediated proteins, including P-glycoprotein (P-gp), mul...
