Spleen [68Ga]Pentixafor uptake is positively associated with peripheral blood leukocyte and/or platelet counts in neuroendocrine tumors, NSCLC and SCLC. A Correlation of spleen-to-liver ratio (SUVmaxSpleen/SUVmeanSpleen) with peripheral leucocyte count in patients with neuroendocrine tumors, n = 25 and NSCLC, n = 9. B Correlation of spleen-to-liver ratio (SUVmaxSpleen/SUVmeanSpleen) with peripheral platelet count in patients with adrenal tumors, n = 31; neuroendocrine tumors, n = 25; NSCLC, n = 9 and SCLC, n = 13. All statistical analyses were performed using simple linear regression. R2 and P values as indicated on the graphs
