Core Tip

Core Tip: In this review we try to clarify definition of mixed neuroendocrine (NE) non-NE tumours that have been changed along past years and analyze available evidence about their diagnosis and treatment options according to their location and extension. We have to bear in mind that we do not have validated protocols or clinical guidelines on the management of this group of diseases, although most authors propose treating mixed NE non-NE neoplasm with the high-grade NE component as treatment target. In any case, the lack of high-quality scientific evidence, based on randomised clinical trials, makes it essential to deepen our knowledge of this group of neoplasms.
