Collaborative Stage

*The selection of the stage table for AJCC 6 staging of ocular adnexal lymphoma depends on the value of the CS Extension code. If an obsolete CS Extension code is used, the stage grouping is derived directly from the CS Extension code as shown in the AJCC TNM 6 Stage CSv1 table. For all other CS Extension codes, the stage grouping 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" is appended to Stage I-IV in both tables based on coding of CS Site-Specific Factor 2, Systemic Symptoms at Diagnosis.
