Collaborative Stage

Collaborative Stage for TNM 7 - Revised 11/11/2010 [ Schema ]

LymphomaOcularAdnexa

CS Lymph Nodes

Note 1: Peripheral nodes are located in the upper and lower limbs, including axillary and inguinal nodes. Central lymph nodes are located in the trunk, including mediastinal, para-aortic, and mesenteric nodes.
Note 2: Involvement of peripheral and central lymph nodes, distant nodes for ocular adnexal lymphomas, is coded in CS Lymph Nodes and not in CS Mets at DX.

*Stage grouping for AJCC 6 staging of ocular adnexal lymphoma is derived from a combination of CS Extension, CS Lymph Nodes, and CS Mets at DX codes as shown in the AJCC TNM 6 Stage table. A or B classification is appended to Stage I-IV based on coding of CS Site-Specific Factor 2, Systemic Symptoms at Diagnosis.
