Collaborative Stage

Note 1: According to AJCC, "Except for pTis and pT4, extent of primary tumor for TNM is classified by radical orchiectomy. TX is used for other categories in the absence of radical orchiectomy." For Collaborative Staging, this means that the categories of T1, T2, and T3 are derived only when Site Specific Factor 4 indicates that a radical orchiectomy was performed. See the Extension Orchiectomy LVI table for details.
Note 2: ONLY assign code 300 (localized, NOS) when no further information is available to assign code 160, 200, 320 or 330.
Note 3: If the ONLY information regarding tumor extension is the physician's statement of the T category, assign code 320, 330, 550 or 810.

^ For extension codes 160, 200, 300, 320, 330, 460, 500 and 550 ONLY, the T category for AJCC 7th Edition staging is assigned based on the values of CS Extension, Site-Specific Factor 4 (Radical Orchiectomy Performed), and Lymph-vascular Invasion, as shown in the AJCC 7 Extension Orchiectomy LVI Table.
* For cases coded under CSv1 (CS Version Input Original less than 020000) ONLY and with extension codes 100, 150, 160, 200, 300, 320, 330, 400, 450, 460, 500 and 550, the T category for AJCC 6th Edition staging is assigned based on the values of CS Extension, Lymph-vascular Invasion, and Site-Specific Factor 4 (Radical Orchiectomy Performed), as shown in the AJCC 6 CSv1Extension Orchiectomy LVI Table. For cases coded under CSv2 (CS Version Input Original greater than 020000) ONLY and with extension codes 100, 150, 160, 200, 300, 320, 330, 400, 450, 460, 500 and 550, the T category for AJCC 6th Edition staging is assigned based on the values of CS Extension, Site-Specific Factor 4 (Radical Orchiectomy Performed), and Lymph-vascular Invasion, as shown in the AJCC 6 CSv2 Extension Orchiectomy LVI Table.
