For instance, Jeong et al. reported a strong correlation between CD68+ TAM immunostaining and 18F-fluoro-deoxyglucose (FDG) uptake on PET imaging (FDG SUVmax; rho = 0.369; P < 0.001 and 40% TLG uptake; rho = 0.355; P < 0.001) in non-small cell lung cancer (NSCLC). Here, CD68 is linked to non-small cell lung carcinoma.
