Background: Diarrhea is a common quality of life limiting symptom seen in neuroendocrine tumor patient. Diarrhea in these patients could be due to excessive serotonin production, secondary to post-operative short gut syndrome, steatorrhea from somatostatin analogs, bile acid colitis or intestinal bacterial overgrowth. In this study we summarize our single center experience with enterade. Methods: Medical records of all the NET patients treated with enterade for symptomatic diarrhea were retrospectively reviewed after appropriate IRB approval. Patients were treated at Markey cancer center between May 2017-June 2019. Results: Total 98 patients were offered enterade. enterade was instructed to be taken as one 8 Oz bottle BID for 1 week. Antidiarrheal efficacy data was available on 49 patients at the time of abstract submission. 37 (75%) patients had GEPNETs, 8 had bronchial NETs, 1 gynecological NET and 3 patients had unknown primary. 28 (57%) patients had history of prior bowel resection either for primary neuroendocrine tumor resection or debulking. 28 (57%) patients were on somatostatin analog at the time of initiation of enterade. 42 (85%) out of 49 patients reported subjective improvement in diarrheal symptoms. 27 (64%) out of these 42 responders reported at least 50 percent reduction in diarrhea frequency. Conclusions: 85% (42/49) neuroendocrine tumor patients reported improvement in diarrhea with enterade. 64% (27/42) reported more than 50% reduction in diarrhea frequency. A prospective Phase II study of enterade in neuroendocrine tumor patients with quality of life limiting diarrhea is currently being conducted (NCT03722511).
