The Difficulties of Response Assessment After Peptide Receptor Radionucleotide Therapy (PRRT): An Unusual Case of Symptomatic Pseudoprogression Abstract #1394

Introduction: In previous studies patient symptoms, biochemistry (including chromogranin A) and imaging using RECIST criteria have been used to assess tumour response to PRRT.
Aim(s): The optimal methods to assess tumour response to PRRT remains unclear.
Materials and methods: We present the case of a forty-nine year old male with a grade 2 (KI-67 4.7%) well-differentiated metastatic rectal neuroendocrine carcinoma with liver, lymph node and bone metastases. All tumours were gallium DOTATATE avid but had previously enlarged on somatostatin analogue therapy.

#13 Neoadjuvant peptide receptor radionuclide therapy for an inoperable neuroendocrine pancreatic carcinoma
Introduction: Pancreatic endocrine tumors (pNETs) are rare but are among the most common neuroendocrine neoplasms of the abdomen. At diagnosis, many of them are already advanced and difficult to treat.

#26 Molecular imaging of gastroenteropancreatic neuroendocrine tumours with Ga-68 DOTANOC PET/CT and correlation with an immunhistochemical quantification of somatostatin receptors using novel monoclonal and polyclonal antibodies
Introduction: Receptor PET/CT with somatostatin analogues marked with Gallium-68 (SMS-R-PET/CT) is currently the golden standard in diagnosing gastroenteropancreatic neuroendocrine tumors (GEP-NET), which are known for an overexpression of somatostatin receptors (SSTRs).

#80 Metastatic growth hormone secreting pituitary carcinoma treated with peptide receptor radionuclide therapy
Introduction: Pituitary carcinoma (PC) is an extremely rare condition defined by the presence of adenohypophyseal neoplastic tissue outside the pituitary. Clinical experience regarding diagnosis, management and prognosis of PC is very limited. Growth hormone (GH) secreting PC is even rarer and represents a particular challenge to clinical practice. Therapeutic modalities utilized to treat PC include surgery, radiation, hormonal therapy, and cytotoxic drugs. Peptide Receptor Radionuclide Therapy (PRRT) is an emerging therapeutic modality that involves the targeted delivery of an ablative dose of radiolabelled somatostatin analog. PRRT has been applied to various neuroendocrine tumors and results in prolonged survival and enhanced quality of life. As yet, this therapy has not been applied to malignant pituitary tumors.

#117 Synchronous appendiceal neuroendocrine carcinoma and mucinous cystadenocarcinoma: a case report
Introduction: Appendiceal tumors with histological features of both carcinoids and adenocarcinomas are very rare. Carcinomas of the appendix are usually mucinous adenocarcinomas with a tendency to produce peritoneal pseudomyxoma and without metastatic spread until late in the disease course. Carcinoid tumors of the appendix are a common incidental finding.
