Spleen [68Ga]Pentixafor uptake levels show a wide variety within different entities, and are not affected by systemic treatment. A Comparison of spleen-to-liver ratios (SUVmaxSpleen/SUVmeanLiver) of patients with adrenal cancer, n = 31; cholangiocarcinoma, n = 4; DSRCT, n = 9; hepatocellular carcinoma, n = 6; mesothelioma, n = 6; neuroendocrine Tumors, n = 25; NSCLC, n = 9; pancreatic adenocarcinoma, n = 9; renal cell carcinoma, n = 4; sarcoma, n = 7; SCLC, n = 13 and control, n = 5. B Comparison of spleen-to-liver ratios (SUVmaxSpleen/SUVmeanLiver) of patients of all tumor entities included in the study, comparing patients without ongoing (no systemic treatment, n = 85) to those with an ongoing systemic therapy or systemic treatment within the last month prior to imaging (systemic treatment, n = 63)
