Tirosh et al. [16] noted that CgA correlated with total NET tumor volume assessed by SSTR PET/CT in patients with sporadic panNETs (n = 112), while PP correlated with NET tumor volume in the subgroup of hereditary panNETs, including 39 patients with MEN1 and 42 with von Hippel-Lindau disease. The gene discussed is MEN1; the disease is neoplasm.
