Collaborative Stage

Note 1: The parenchyma of the kidney includes the following structures: cortex (outer layer of kidney) and renal columns; medulla, medullary rays, renal pyramids, and renal papillae; nephrons (renal corpuscle, loops of Henle, proximal and distal tubules, collecting duct), glomerulus, and Bowman's capsule. The most common site for renal parenchymal cancer to develop is in the proximal convoluted tubule. Tumor extension from one of these structures into another would be coded to 100 unless there were further signs of involvement.
Note 2: Information about invasion beyond the capsule, venous involvement, and ipsilateral adrenal gland involvement is collected in this field and in Site-Specific Factors 1, 2 and 3 because beyond contributing to the overall assessment of extent of tumor, these factors can have an independent effect on prognosis.
Note 3: ONLY assign code 300 (localized, NOS) when no further information is available to assign code 100, 200 or 310-360.
Note 4: If the ONLY information regarding tumor extension is the physician's statement of the T category, assign code 310-360, 605, 610, 620, 625 or 810. (Refer to CS Tumor Size table for instructions on coding tumor size if assigning code 310-360).

^ For codes 100, 200, 300, 310, 320, 330, 340, 350, and 360 ONLY, the T category for AJCC 7 is assigned based on the value of tumor size, as shown in the Extension Size Table AJCC 7 for this site.
* For codes 100, 200, 300, 310, 320, 330, 340, 350, and 360 ONLY, the T category for AJCC 6 is assigned based on the value of tumor size, as shown in the Extension Size Table AJCC 6 for this site.
