Prostate cancer has a highly tumor-restricted prostate-specific membrane antigen (PSMA) and may be the ideal solid-organ malignancy for treatment with radioimmunotherapy. Encouraging results using lutetium-177-labeled anti-PSMA monoclonal antibody J591 from a phase II study by Tawaga and colleagues support the continued clinical and preclinical development of radioimmunotherapy for solid tumors.

Neuroendocrine tumours (NETs) are a heterogeneous group with significant variation in morphological characteristics and functional behaviour. This poses challenges in terms of both biochemical and imaging assessment. Somatostatin receptor (sst) overexpression is documented in several malignancies. The sst subtype 2 (sst2) is overexpressed in NETs [1] and can be targeted for both somatostatin re...

The study assessed a radiolabeled depsipeptide conjugate (68Ga-DOTA-TBIA101) for its potential as an imaging agent targeting infection or infection-associated inflammation. 68Ga-labeled DOTA-TBIA101 imaging was performed in (NZR1) healthy rabbits; (NZR2) rabbits bearing muscular sterile inflammation and Staphylococcus aureus (SA) infection; and (NZR3) rabbits infected with Mycobacterium tubercu...

The biodistribution of the anti-CD37 radioimmunoconjugate (177)Lu-tetraxetan-tetulomab ((177)Lu-DOTA-HH1) was evaluated. Biodistribution of (177)Lu-tetraxetan-tetulomab was compared with (177)Lu-tetraxetan-rituximab and free (177)Lu in nude mice implanted with Daudi lymphoma xenografts. The data showed that (177)Lu-tetulomab had a relevant stability and tumor targeting properties in the human l...

UNLABELLED It is highly desired to develop new imaging probes for early detection of melanoma as early diagnosis and prompt surgical removal are a patient's best hope for a cure. The purpose of this study was to determine whether (99m)Tc- and (111)In-labeled alpha-melanocyte-stimulating hormone (alpha-MSH) peptides could be used as imaging probes for primary and metastatic melanoma using dual-m...

177Lu-DOTA-HH1 (177Lu-HH1) is a novel anti-CD37 radioimmunoconjugate developed to treat non-Hodgkin lymphoma. Mice with subcutaneous Ramos xenografts were treated with different activities of 177Lu-HH1, 177Lu-DOTA-rituximab (177Lu-rituximab) and non-specific 177Lu-DOTA-IgG1 (177Lu-IgG1) and therapeutic effect and toxicity of the treatment were monitored. Significant tumor growth delay and incre...
