Extension Size Pair AJCC 6 Table
- Note: For CS Extension codes 150-180, 635, and 640, the T category for AJCC 6 staging is assigned based on the values of tumor basal diameter, recorded in CS Site-Specific Factor 2, and thickness, recorded in CS Site-Specific Factor 3. Diameter and thickness are mapped to tumor size pairs in the Tumor Size Pair AJCC 6 Table, and the CS Extension codes and tumor size pairs are mapped to T as shown in this table.
