Successful palliative peptide receptor radionuclide therapy for impending compression of vena cava due to unresectable liver metastasis of neuroendocrine tumor.

Abstract

We present the case of a 77 year old male patient with metastatic pancreatic neuroendocrine tumor (NET). The patient was initially treated by extensive surgical resection that however, led to severe complications with delayed recovery. During follow-up, a number of new liver metastases were detected, one of which was in segment I with impending compression of the inferior vena cava. Due to age and general condition of the patient, instead of further surgical treatment, the patient received four cycles of 177Lu-DOTATOC resulting in an overall partial response with successful tumor reduction in liver segment I, resolving an impending compression of vena cava.
