Endocervical adenocarcinoma classification systems: The 2014 World Health Organization system and the International Endocervical Adenocarcinoma Criteria and Classification (IECC, 2018) system. The WHO classification system categorizes tumors based primarily on morphology, while the IECC system divides tumors into those that are human papillomavirus associated (HPVA) and those that are not (NHPVA) based on more detailed diagnostic criteria, resulting in the reclassification of many WHO-defined tumors.
