“Lung neuroendocrine tumors (LNETs) are uncommon cancers and there is a paucity of randomized evidence to guide practice. As a result, current guidelines from different neuroendocrine tumor societies vary considerably. There is a need to update and harmonise global consensus guidelines. This paper reports best practice guidelines produced by a collaboration between the Commonwealth Neuroendocrine Tumour Research Collaboration (CommNETs) and the North American Neuroendocrine Tumor Society (NANETS).”
