Abstract
BackgroundNeuroendocrine tumors are rare, heterogeneous neoplasms that produce a wide variety of clinical symptoms. Diarrhea in neuroendocrine tumors is incredibly common and is usually benign in nature. We report two extreme cases of diarrhea in metastatic neuroendocrine tumors that threatened fatality and provide evidence for steroids as a novel agent in the management of vasoactive intestinal peptide tumors.Case presentationA 63-year-old Caucasian male with a grade 2 (Ki-67 17%) metastatic small bowel neuroendocrine tumor, and a 43-year-old female with a grade 2 (Ki-67 5%) metastatic pancreatic vasoactive intestinal peptide tumor. Both patients suffered life-threatening diarrhea despite extensive treatment modalities, including new systemic agents. This case explains how a lack of compliance and patient under-reporting of symptoms contributed to their challenging clinical course. Only steroids had a significant sustained effect on the diarrhea of the patient with vasoactive intestinal peptide tumor.ConclusionsThis report discusses two rare cases of life-threatening diarrhea in neuroendocrine tumors and stresses the importance of accurate clinical history taking, patient education, and compliance for symptom control. The report suggests steroids as a potential novel pharmaceutical option in the management of vasoactive intestinal peptide tumors; this is of great significance as it may provide a new approach to their management and potentially act as a life-saving agent in other oncology patients.
