However, symptomatic progression eventually occurs and in this scenario of a refractory CSy; several treatment options have been studied such as dose escalation of SSA, interferon and liver-directed therapies. Nevertheless, recent phase III trials have contributed to the understanding and management of this condition. We performed a comprehensive review of interventional studies examining refractory CSy to provide the evidence for current treatment options and propose a treatment sequence %K carcinoid syndrome %K neuroendocrine neoplasm %K somatostatin %K systematic review %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5298401/
