Clinical and epidemiological profile of neuroendocrine differentiation – A hospital-based retrospective study

#4108

Introduction: Global research on neuroendocrine differentiation (NED) in carcinomas remains limited, despite its distinct clinical features, disease progression, pathology, treatment outcomes, and poor prognosis. At the 2023 ENETS Conference, we presented our findings on NED in gastric cancer and colorectal cancer. However, more studies are essential to better comprehend NED's clinical and epidemiological aspects.

Aim(s): The study aims to explore the incidence of NED in a variety of tumors.

Materials and methods: This retrospective study analyzed histopathological samples from patients diagnosed with malignant tumors, employing immunohistochemical techniques to detect NED markers (ChrA, Syno, CD56). The morbidity and prognosis of NED patient would be analysised subsequently. Inclusion criteria were pathologically confirmed breast cancer (BC), lung cancer (LC), esophageal cancer (EC) and prostate cancer (PC) with no prior neoadjuvant chemotherapy or radiotherapy received before surgery. Patients aged 18-75 years with normal organ functions were enrolled.
