Answer:
Stage IV - There is a primary tumor, lymph node involvement and metastases.
Explanation:
Staging is the extent of spread of tumor within the patient.
The American Joint Committee on Cancer (AJCC) divides all cancers into Stages 0 - IV, incorporating into each stage several TNM (tumor/node/metastasis) stages usually with the same prognosis.
Staging is essential in determining the patient prognosis.
The approximate 5-year survival rate for colorectal cancer patients of all stages is 64.4% (In the United States) and survival is inversely related to stage.
Surgery usually provides the only curative option for patients diagnosed with Stage IV colon cancer.
