Collaborative Stage

Collaborative Stage for TNM 7 - Revised 10/26/2010 [ Schema ]

LacrimalGland

CS Extension

Note 1: AJCC considers "in situ carcinoma of lacrimal gland" an impossible diagnosis. Any case so coded is mapped to TX for AJCC stage and in situ Summary Stage.
Note 2: As noted by the AJCC, "As the maximum size of the lacrimal gland is 2 cm, T2 and greater tumors will usually extend into the orbital soft tissue."
Note 3: Periosteum is a fibrous membrane that wraps the outer surface of bones.

^ For CS Extension codes 100, 300, and 600-630 ONLY, the T category for AJCC 7 staging is assigned based on the value of CS Tumor Size as shown in the Extension Size AJCC 7 Table.
* For CS Extension codes 100, 300, and 610-650 ONLY, the T category for AJCC 6 staging is assigned based on the value of CS Tumor Size as shown in the Extension Size AJCC6 Table.
