Gastroenteropancreatic Neuroendocrine Tumor

509 Background: Based on SEER database, gastroenteropancreatic neuroendocrine tumor incidence has increased 6 fold from 1 in 100,000 cases to about 6 in 100,000 cases over past 3 decades. North American Neuroendocrine Tumor Society estimates that over 100,000 GEPNET patients are currently living in the United States. One of the common quality of life limiting symptom seen in GEPNET patient is diarrhea. 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. A novel amino acid based oral rehydration solution (Enterade) is currently being evaluated in a Phase II clinical trial for antidiarrheal effects in post bone marrow transplant patients (NCT02919670). We conducted a pilot study of Enterade in neuroendocrine tumor patients with quality of life limiting diarrhea to evaluate its antidiarrheal efficacy. Methods: Medical records of all the GEPNET patients treated with Enterade for symptomatic diarrhea were evaluated. Patients were treated at Markey cancer center between May 2017-August 2017. Results: Total 8 patients were treated with Enterade. Five were small bowel NETs and 3 were pancreatic NETs. Five patients had prior bowel resections for removal of primary tumor; 5 patients were on somatostatin analogs at the time of initiation of Enterade. Five (62%) patients reported improvement in diarrhea within 6 days of initiating Enterade. The responders had 50 % reduction in their stool output. Mean stools dropped from 6 per day to 3 per day in responders. Conclusions: These pilot data suggest that Enterade may be an effective option in diarrhea control in NET patients. A prospective Phase II study of Enterade in gastroenteropancreatic neuroendocrine tumor patients with quality of life limiting diarrhea is planned.

Abstract Background Neuroendocrine tumors, although relatively rare in incidence, are now the second most prevalent gastrointestinal neoplasm owing to indolent disease biology. A small but significant sub-group of neuroendocrine tumor patients suffer from diarrhea. This is usually secondary to carcinoid syndrome but can also be a result of short gut syndrome, bile acid excess or iatrogenic etiologies. Recently, an amino acid based oral rehydration solution (enterade® Advanced Oncology Formula) was found to have anti-diarrheal properties in preclinical models. Methods A retrospective chart review of all NET patients treated with enterade® AO was performed after IRB approval. Results Ninety-eight NET patients who had received enterade® AO at our clinic from May 2017 through June 2019 were included. Patients (N = 49 of 98) with follow up data on bowel movements (BMs) were included for final analysis. Eighty-four percent of patients (41/49) had fewer BMs after taking enterade® AO and 66% (27/41) reported more than 50% reduction in BM frequency. The mean number of daily BMs was 6.6 (range, 3–20) at baseline before initiation of therapy, while the mean number of BMs at 1 week time point post enterade® AO was 2.9 (range, 0–11). Conclusions Our retrospective observations are encouraging and support prospective validation with appropriate controls in NET patients. This is first published report of the potential anti-diarrheal activity of enterade® AO in NET patients.

Cell Proliferation Index

Pancreatic neuroendocrine tumor (PNET) refer to tumors originating from the islet of Langerhans and shows various prognosis based on the presence or absence of symptoms due to hormone secretion, the Ki-67 cell proliferation index, and the histologic grade, and according to the degree of disease progression defined by the tumor-node-metastasis (TNM) stage classification. The purpose of medical treatment for PNET is to control symptoms or inhibit tumor growth. Somatostatin analogues can be administered for the purpose of controlling symptoms caused by the secretion of specific hormones, and are accepted as effective drugs for inhibiting the progression of G1/G2 tumors based on World Health Organization (WHO) classification with a Ki-67 cell proliferation index less than 20%. Among the molecularly targeted agents, everolimus and sunitinib can be considered in patients with WHO G1/G2 PNET showing progression after somatostatin analog therapy. Cytotoxic chemotherapy is generally administered to patients with large tumor volume and rapidly progressing metastatic NET, and etoposide/cisplatin combination therapy has been considered as a standard treatment. For the patient group of Grade 3 PNET (well differentiated) newly classified by the WHO 2017 classification, guidelines for standard treatment have not yet been established. As it has been reported, studies are needed to evaluate the treatment response rate of somatostatin analogues or molecularly targeted therapies for the patient with Grade 3 PNET. It is important to consider a multidisciplinary approach with all possible treatment options including medical treatment, radical resection of primary or metastatic lesions, liver-directed therapies, and peptide receptor radionuclide therapy for the patients with PNET.
