Immunohistochemical Expression of Estrogen and Progesterone Receptors in Neuroendocrine Tumors

#1544

Introduction: Expression of progesterone (PR) and estrogen receptor (ER) in some neuroendocrine tumors (NET) raises the possibility of hormonal regulation in these tumors, but those prevalence and clinical implication are unknown.

Aim(s): To determine presence and prognostic value of ER and PR in NET.

Materials and methods: Immunohistochemical expression of ER and PR were retrospectively examined in NET treated in a single institution between 2007 and 2015 and correlated with clinicopathological features and survival.
