Overview

World health organization classified nasopharyngeal carcinoma into 3 types : keratinizing, nonkeratinizing (differentiated, undifferentiated) and basaloid squamous cell carcinoma.

Classification

World Health Organization (WHO) classification (2005) for nasopharyngeal carcinoma (NPC):[1][2]

Classification Former name EBV Prevalence Prognosis
Keratinizing Type 1, squamous cell carcinoma -ve almost 1/4 of NPC cases poor
Nonkeratinizing, differentiated Type 2, transitional carcinoma +ve less than 1/6 of NPC cases good
Nonkeratinizing, undifferentiated Type 3, lymphoepithelial carcinoma +ve most common good
Basaloid squamous cell carcinoma (BSCC) least common poor
