Ch 15 - Cutaneous Squamous Cell Carcinoma of the Head and Neck Flashcards
Tx
Primary tumor cannot be assessed
Tis
Carcinoma in situ
T1
Tumor smaller than 2cm in greatest dimension
T2
Tumor 2cm or larger, but smaller than 4cm in greatest dimension
T3
Tumor 4cm or larger in maximum dimension or minor bone erosion or perineural invasion or deep invasion*
*Deep invasion is defined as invasion beyond the subcutaneous fat or >6mm (as measured from the granular layer of adjacent normal epidermis to the base of the tumor); perineural invasion for T3 classification
is defined as tumor cells within the nerve sheath of a nerve lying deeper than the dermis or measuring 0.1 mm or larger in caliber, or presenting with clinical or radiographic involvement of named nerves without skull
base invasion or transgression.
T4a
Tumor with gross cortical bone/marrow
invasion
T4b
Tumor with skull base invasion and/or skull
base foramen involvement
