PATHOLOGY OF ORAL CANCERS

PATHOLOGY OF ORAL CANCERS

The vast majority (>95%) of oral cavity cancers are squamous cell carcinomas (OCSCCs). The World Health Organization (WHO) tumour grading system, based on cellular di ff erentia - tion, is routinely used in pathological analysis and diagnosis of OCSCC. The histological parameters routinely described in OCSCC include: /uni25CF histological type; /uni25CF tumour grade/di ff erentiation; /uni25CF pattern of invasion; /uni25CF tumour thickness and DOI; /uni25CF perineural invasion (PNI); /uni25CF lymphovascular invasion (LVI); /uni25CF bone involvement; /uni25CF nodal metastases.
