Multimodality treatment for gastric carcinoid tumor with liver metastases.
Carcinoid tumors are the most common neuroendocrine tumors in the gastrointestinal tract, and between 10% and 30% of these tumors are gastric in origin. Three types of gastric carcinoid tumors are recognized: type I, associated with chronic atrophic gastritis type A; type II, associated with multiple endocrine neoplasia; and type III, sporadic and the most malignant. We present a patient with an aggressive, sporadic-type gastric carcinoid that metastasized to the liver. Her symptomatic treatment included the somatostatin analog octreotide. Octreotide scintigraphy demonstrated that this tumor avidly bound the peptide. The patient's gastric carcinoid (assessed by endoscopy and endoscopic ultrasound) regressed and she underwent hepatic artery embolization for her liver metastases. After initial partial CT resolution the tumor grew, compressing the inferior vena cava. The patient underwent orthotopic liver transplant with excellent recovery, although she was subsequently found to have two small lung metastases. She has responded well to adjuvant Indium-111 octreotide receptor targeted therapy. This case highlights the therapeutic options for metastatic neuroendocrine tumors, including liver transplantation and adjuvant receptor targeted therapy.
