Abstract:
      Treating metastatic gastric neuroendocrine neoplasms (gNENs) is challenging, especially for those with progressive disease during somatostatin analog processing. In this report, we present a case of a welldifferentiated grade 2, type 3 gNEN with metastatic hepatic portal lymph nodes. EDGE non-invasive radiosurgery (800 cGy × 5 F) was performed to radiate the metastatic hepatic portal lymph nodes. Three months after the hyperfractionated radiotherapy, no signs of metastatic hepatic portal lymph nodes were observed using 8Ga-dotatate positron emission tomography-computed tomography or magnetic resonance imaging. Therefore, EDGE non-invasive radiosurgery could be a potential option for treating local metastatic nodes.
