Vasoactive Intestinal Peptide–Secreting Tumors: A Review

Vasoactive intestinal peptide–secreting tumors (VIPomas) are a group of rare neuroendocrine tumors, which cause a typical syndrome of watery diarrhea. Most of these tumors are found in the pancreas and are usually detected at a later stage. Although curative resection is not possible in most of these tumors, both symptom and tumor control can be achieved by a multidimensional approach, to enable a long survival of most patients. There are no clear-cut guidelines for the management of VIPomas because of the rarity of this neoplasm and lack of prospective data. In this review, we discuss the available evidence on the clinical features and management of these rare tumors.

A 50-year old man was admitted for evaluation of progressive, chronic diarrhea with loss of weight and recurrent hypokalemia. Eventually, a neuroendocrine tumor of the pancreas secreting VIP (VIPoma) could be diagnosed. The patient was cured by a pancreaticoduodenectomy (Whipple procedure). With this case, we want to highlight the importance of a structured work-up in chronic diarrhea including thorough history and clinical assessment, laboratory tests and imaging studies.PMID:34465193 | DOI:10.1024/1661-8157/a003714

ConclusionIn MEN1 patients, pancreatoduodenectomy can be used to control hormone secretions (gastrin, glucagon, VIP) and to remove large NETs. PD was found to control gastrin secretions in about 60% of cases.

Authors: Lam AK, Ishida H Abstract The nomenclature and classification of pancreatic neuroendocrine neoplasms has evolved in the last 15 years based on the advances in knowledge of the genomics, clinical behaviour and response to therapies. The current 2019 World Health Organization classification of pancreatic neuroendocrine neoplasms categorises them into three groups; pancreatic neuroendocrine tumours (PanNETs)(grade 1 grade 2, grade 3), pancreatic neuroendocrine carcinomas and mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) based on the mitotic rate, Ki-67 index, morphological differentiation and/or ...

Conclusion: Patients with suspected functional PanNENs should have a systematic endocrine examination at diagnosis. Multidisciplinary collaborations are essential for precise diagnosis and tumor localization. A successful surgery or other targeted therapies can improve the prognosis of patients with such rare but complex disorders. PMID: 33204258 [PubMed]
