Colorectal Cancer: Staging

Staging systems for cancer in general have evolved over time. They continue to change as scientists learn more about cancer. Some staging systems cover many types of cancer; others focus on a particular type. The common elements considered in most solid staging systems are:

  • Location of the primary tumor.
  • Tumor size and number of tumors.
  • Lymph node involvement (spread of cancer into lymph nodes).
  • Cell type and tumor grade (how closely the cancer cells resemble normal tissue).
  • Presence or absence of metastasis.

CRC: Screening

The appropriate age at which CRC screening should be discontinued is not known.

Screening studies have generally been restricted to patients younger than 80 years of age, with colorectal cancer mortality rates beginning to decrease within 5 years of initiating screening.

Yield of screening should increase in older persons (because of higher incidence of colorectal cancer), but benefits may be limited as a result of competing causes of death.

Discontinuing screening is reasonable in patients whose age or comorbid conditions limit life expectancy.

CRC: Surgery

Surgery is the most common treatment for colorectal cancer. It is a type of local therapy. It treats the cancer in the colon or rectum and the area close to the tumor. Small malignant polyps may be removed from the colon or upper rectum with a colonoscope. Some small tumors in the lower rectum can be removed through the anus without a colonoscope.

Types of surgery include:

  • Polypectomy
  • Colon Resection:
    • Colectomy
    • Colostomy
