T: Size

•T1,T2,T3,T4 - size and/or extension of primary tumor

N: Degree of regional lymph node involvement
•Nx - Lymph nodes cannot be evaluated
•N0 - Tumor cells absent from regional lymph nodes
•N1 - Regional lymph mets present
•N2 - Tumor spread to an extent, between N1 & N3
•N3 - Tumor spread to more distant or numerous regional lymph nodes

M: Presence of metastasis
•Mx - Distant metastasis cannot be evaluated
•M0 - No distant metastasis
•M1 - Metastasis to distant organs (beyond regional lymph nodes)
