A National Pathology Registration Analysis of Applied Terminology in Pulmonary Neuroendocrine Tumors/Carcinomas: Is the WHO 2004 Classification in Line with Clinical Practice?

#1184

Introduction: Nomenclature of the WHO 2004 should be used for pulmonary neuro-endocrine tumors (NET) and carcinomas (NEC) classification.

Aim(s): To analyze if current practice is in line with the WHO 2004 terminology (TI), conclusions (CN) of pathology reports of NET/NEC diagnosed in the Netherlands were analyzed.

Materials and methods: CN of NET/NEC diagnosed from 2003-2012 were selected from the Dutch Pathology Registry through 4 queries of SNOMED codes (e.g. NET grade I, M8242_) and ‘free text’ (e.g. carcinoma + endocrine). All CN were screened; CN describing non-lung, non-NET/NEC, small cell cancer, or autopsy were excluded. CN were clustered into biopsy/cytology (Bx) or resection (Rx) and compared with current TI.
