ALB and neoplasm: Unlike earlier studies utilizing albumin-binding molecules to improve tumor accumulation, which reported sustained tumor radioactivity even at later time points post-injection [24,25], our findings showed a marked decline in tumor accumulation for [125I]bcRGDpal and [125I]bcRGDiba at 24 h post-administration (0.3% ID/g and 0.5% ID/g, respectively), suggesting poor tumor retention.
