Objectives

Narrative objectives1

To analyze whether a combination of systemic venous sampling of FGF23 and imaging studies, such as FDG-PET/CT and octreoscan, shows higher sensitivity and positive predictive value compared to imaging studies alone to localize responsible tumors in TIO.

Interventions/Control_1

Perform octreoscan and FDG-PET/CT in patients with probable TIO. Perform systemic venous sampling of FGF23 in those with no accumulation on these imaging studies or those with tumors that need more conclusive localization before high-risk surgery.Collect 22 blood samples from major veins of the patients using catheter that inserted in the femoral vein.Measure serum FGF23 value in each sample using human FGF23 ELISA kit. The region where serum FGF23 value is 1.3 times higher than that of the minimum value is considered as a candidate.If the localization of the tumor is clarified by these studies, either biopsy or surgical removal of the tumor is performed. Immunohistochemical staining for FGF23 is performed on tissue samples.
