Collaborative Stage

Note 1: The substantia propria is the stromal tissue of the conjunctiva underlying the epithelium. The bulbar conjunctiva covers the eyeball, the palpebral conjunctiva lines the eyelids, and the forniceal conjunctiva covers the junction of the eyelid and eyeball. The caruncle is the fleshy prominence at the inner corner of the eye lined by conjunctival epithelium.
Note 2: Tumors confined to the epithelium are staged as Tis in AJCC 7th Edition. Unless corneal extension is present, they are staged as T1 in AJCC 6th Edition.
Note 3: Quadrants of involvement are coded in CS Site-Specific Factor 3.

^ For Extension codes 300, 310, 315, 320, 325, 330, 335, 445, 450, 470, 475, 480, 485, 490, 495, and 500, the pathologic T category is assigned based on the value of CS TS/Ext Eval and thickness recorded in CS SSF 1, as shown in the Pathologic Eval Extension Thickness AJCC 7 table (eval codes 2,3,6,8). This table is also used if the CS TS/Ext Eval code is blank and CS SSF 1 does not equal 998. The clinical T category is assigned based on the value of CS TS/Ext Eval and quadrants recorded in CS SSF 2, as shown in the Clinical Eval Extension Quadrants AJCC 7 table (eval codes 0,1,5,9). This table is used if the CS TS/Ext Eval code is blank and CS SSF 1 equals 998.
^^For Extension codes 710, 720, 730, and 740, the T category is assigned based on the value of CS TS/Ext Eval as shown in the Eval Extension T3 AJCC 7 table for this site.
* For Extension codes 005, 300, 310, 315, 320, 325, 330, 335, 415, 425, 430, and 435, the pathologic T category for AJCC 6th Edition staging is assigned based on the value of CS TS/Ext Eval and thickness recorded in CS SSF 1 as shown in the Pathologic Eval Extension Thickness AJCC 6 table (eval codes 2,3,6,8). This table is also used if the CS TS/Ext Eval code is blank and CS SSF 1 does not equal 998. The clinical T category for AJCC 6th Edition staging is assigned based on the value of CS TS/Ext Eval as shown in the Clinical Eval Extension AJCC 6 table (eval codes 0,1,5,9) for this site. This table is used if the CS TS/Ext Eval code is blank and CS SSF 1 equals 998.
