Impact of Small Cell (SC) versus (vs.) Non-Small Cell (nSC) Morphology on Outcomes of Patients (pts) with Extra-Pulmonary, Poorly Differentiated Neuroendocrine Carcinoma (EP-PD-NEC)

#3027

Introduction: The 2018 SEER data indicates EP-PD-NEC morphology (SC vs. nSC) may impact patient outcomes.

Aim(s): To explore differences in clinical-pathological/survival/treatment outcomes of SC vs. nSC EP-PD-NECs.

Materials and methods: Multicentre data from pts with EP-PD-NEC for whom tumour tissue could be reviewed (2019 WHO) was retrospectively analysed.
