Management of a Patient With Metastatic Gastrointestinal Neuroendocrine Tumor and Meningioma Submitted to Peptide Receptor Radionuclide Therapy With 177 Lu-DOTATATE

Abstract

A 76-year-old woman affected by pancreatic neuroendocrine tumor previously subjected to surgery with progressive liver disease and a concomitant mild symptomatic meningioma of the left pontocerebellar angle underwent 4 cycles of peptide receptor radionuclide therapy with 177 Lu-DOTATATE. A prophylactic therapy with corticosteroids was carried out before each treatment cycle, and the neurosurgery unit was alerted in case of cerebral edema and related neurologic symptoms. A 68 Ga-DOTATOC PET/CT scan performed after the completion of the 4 cycles' treatment documented a hepatic partial response and a substantial stability of the brain mass. No neurological complications occurred during treatment and follow-up.
