The volumetric PET parameters, whole-body Metabolic Tumor Volume (MTV), whole-body TLG and standard uptake value (SUV) peak, were quantified using 50%-isocontour volumes of interests (VOIs) and correlated with the following serologic parameters: lactate dehydrogenase (LDH), S-100 protein, C-reactive protein (CRP) and alkaline phosphatase (AP). Here, CRP is linked to neoplasm.
