CS Extension

Note 1: Periosteum is a fibrous membrane that wraps the outer surface of bones. Cortical bone is the dense compact outer layer of bone.Trabecular, cancellous, or spongy bone (spongiosa) is a porous network of tissue filling the interior of bone, decreasing weight and allowing room for blood vessels and marrow.
Note 2: AJCC assigns T value based on size when bone involvement is limited to the cortex. Involvement through cortical bone is required for assignment of T4a.
Note 3: Use code 300 for localized tumor ONLY if no information is available to assign codes 100, 200, 405, 410, or 415.
Note 4: Use code 405, 410, 415, 778, 810, or 815 if the physician's assignment of T category is the ONLY information available about the extent of the tumor.

^ For Extension codes 100 through 535 ONLY, the T category for AJCC 7th Edition staging is assigned based on the value of CS Tumor Size, as shown in the Extension Size Table for this site.
* For Extension codes 100 through 535 ONLY, the T category for AJCC 6th Edition staging is assigned based on the value of CS Tumor Size, as shown in the Extension Size Table for this site.
