EDGE non-invasive radiosurgery for gastric neuroendocrine hepatic portal lymph node metastases： a case report

摘要

cqvip: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 g NEN 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 8 Ga-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.
