CS Extension

Note 1: AJCC considers "in situ carcinoma of salivary gland" an impossible diagnosis. Any case so coded will be mapped to an unknown AJCC stage, in situ Summary Stage.
Note 2: Periosteum is a fibrous membrane that wraps the outer surface of bones. Mucoperiosteum is a compound structure of mucous membrane and periosteum. Cortical bone is the dense compact outer layer of bone.
Note 3: Use code 300 for localized tumor ONLY if no information is available to assign codes 100 or 305.
Note 4: Use code 305, 310, 408, 625, 810, or 815 if the physician's assignment of T category is the ONLY information available about the extent of the tumor. if the physician's assignment of T category is the ONLY information available about the extent of the tumor.

^For Extension codes 100-350 ONLY, the T category for AJCC 7th Edition staging is assigned based on value of CS Tumor Size as shown in the Extension Size Table for this site.
*For Extension codes 100-350 ONLY, the T category for AJCC 6th Edition staging is assigned based on value of CS Tumor Size as shown in the Extension Size Table for this site.
