Similarly, Dreher et al. showed that [68Ga]Ga-Pentixafor PET/CT imaging detected CXCR4 overexpression in SCLC and other solid tumors, suggesting its role in guiding targeted therapy selection for patients with CXCR4-enriched tumors (Dreher et al., 2024). This evidence concerns the gene CXCR4 and small cell lung carcinoma.
