Note 2: AJCC does not define TNM staging for these sites. Note 3: Adrenal gland primaries (C74.0, C74.1, and C74.9) are included in the Adrenal Gland schema. Note 4: Pituitary gland (C75.1), craniopharyngeal duct (C75.2), and pineal gland (C75.3) primaries are included in the Intracranial Gland schema. &generalsize; CS Extension Code Description TNM 7 Map TNM 6 Map SS77 Map SS2000 Map 000 In situ; intraepithelial, non-invasive NA NA IS IS 050 ERROR NA NA NA 100 Invasive tumor confined to gland of origin NA NA L L 300 Localized, NOS NA NA L L 400 NA NA RE RE 600 NA NA RE RE 800 Further contiguous extension NA NA D D 950 No evidence of primary tumor NA NA U U 999 NA NA U U ¬appcsextevalnontnm; CS Lymph Nodes Note 1: Code only regional nodes and nodes, NOS, in this field.
