A positive expression of oestrogen-receptors has recently been demonstrated in pancreatic neuroendocrine tumours as well as in non-neoplastic islet-cells. This prompted us to systematically analyse the expression of both oestrogen and progesterone receptors in a series of GEP neuroendocrine tumours. We analysed oestrogen- and progesterone-receptor in 69 foregut GEP, 25 midgut GEP and seven hindgut GEP. Namely, the foregut GEP included 53 pancreatic NET. All tumour samples were...
