Key Points

  • An estimated 105,000 new cases of colon cancer were diagnosed in the United States in 2021, of which approximately 39% were localized.
 
  • Stage II cancers are characterized by a lack of metastatic spread or lymph node involvement, and the main treatment is surgical resection of the primary tumor.
 
  • Prognosis after resection is relatively favorable, with an estimated five-year disease-free survival rate of approximately 68–83% with surgery alone.
 
  • In order to eradicate micrometastatic disease following surgery, adjuvant therapy may be considered for patients with a high risk of recurrence, however, the extent to which established prognostic factors can predict response to treatment is not well defined.
