Colon Cancer Prognosis
The prognosis of colon cancer depends on the extension that has the tumor in the colon wall, the presence or absence of lymph nodes, and the presence or absence of metastasis.
There are a number of factors that determine a worse prognosis:
Preoperative CEA elevation above 5 ng / ml.
Existence of venous invasion.
Presented as an obstruction.
Drilling there colon wall.
Certain genetic alterations in tumor cells.
Overall survival of patients with colon cancer five years after radical surgical resection is around 40-50%, but this percentage is distributed differently in relation to different stages, so that in stage A the 5-year survival reaches 75%, whereas in stage D does not exceed 1%.
