Overall Survival of Well-Differentiated Neuroendocrine Tumors Evaluated by F-18-FDG-PET

#470

Introduction: Today, grading, and thereby choice of treatment strategy for patients with neuroendocrine (NE) tumors, is mainly based on the proliferation index, Ki-67. As a supplement to this pathological evaluation, a whole body image analysis could be of value.

Aim(s): To investigate the prognostic value of FDG-PET in patients with WHO grade I and II NE tumors.

Materials and methods: Eighty-one prospectively enrolled patients with NE tumors grade I and II underwent FDG-PET imaging. The prognostic value of the FDG-PET scan was evaluated. There were 47 grade I tumors (Ki-67 index2<20). Follow-up time after the FDG-PET scan was 31 ± 12.6 months (mean ± SD).
