TNM Staging System (Tumor, Node, Metastisis) Tumor T1: Tumor invades submucosa. T2: Tumor invades muscularis propria. T3: Tumor invades through the muscularis propria into the subserosa, or into the pericolic or perirectal tissues. T4: Tumor directly invades other organs or structures, and/or perforates. Node N0: No regional lymph node metastasis. N1: Metastasis in 1 to 3 regional lymph nodes. N2: Metastasis in 4 or more regional lymph nodes. Metastasis M0: No distant metastasis. M1: Distant metastasis present.
Stage Groupings Stage I: T1 N0 M0; T2 N0 M0 Cancer has begun to spread, but is still in the inner lining. Stage II: T3 N0 M0; T4 N0 M0 Cancer has spread to other organs near the colon or rectum. It has not reached lymph nodes. Stage III: any T, N1-2, M0 Cancer has spread to lymph nodes, but has not been carried to distant parts of the body Stage IV: any T, any N, M1 Cancer has been carried through the lymph system to distant parts of the body.
