Colorectal Carcinoma

Also called: Colon cancer, colon carcinoma, adenocarcinoma of the colon

What is colorectal carcinoma?

Colorectal carcinoma is a cancer that can occur anywhere along the colon (large intestine) or rectum (the last few inches of the digestive tract).

Colorectal carcinomas are diagnosed in stages 0 to IV, depending on how severe the disease is:

  • At stage 0, the cancer is still contained within the immediate area where it formed. By stage IV, the cancer has spread outside the colon or rectum to at least one other organ.

How common is colorectal carcinoma?

  • About 150,000 people develop colorectal carcinoma in the United States each year.
  • Childhood colorectal carcinoma is rare. Fewer than 100 U.S. children younger than 20 are affected each year—about one in a million.

When it occurs, childhood colorectal carcinoma most often affects children with the following:

  • A family history of these cancers
  • An inherited condition called familial intestinal polyposis, if the small-intestine polyps (growths) are cancerous

What are the symptoms of colorectal carcinoma?

Symptoms of colorectal carcinoma include the following:

  • Pain in the abdomen (belly)
  • Constipation or diarrhea
  • A lump in the abdomen
  • Unexplained weight loss
  • Loss of appetite
  • Blood in the stool

How is colorectal carcinoma treated?

Colorectal carcinoma treatment is based mainly on the stage when the cancer is diagnosed. For the best chance of a complete cure, the tumor must be completely removed by surgery. If the tumor is too large to start with, chemotherapy and/or radiation may be used to try to shrink it.

  • Stage 0 — If the cancer is small enough, surgeons may remove the tumor along with any precancerous polyps (growths) that may be present. If the tumor is large, surgeons may take out the affected section of the colon or rectum and sew the remaining parts back together.
  • Stage I — Treatment usually involves surgery to remove the cancer along with a small amount of tissue in the area. For most patients, no other treatment is needed.
  • Stages II and III — Surgeons may remove the affected section of the colon or rectum and sew the remaining parts back together.
  • Stage III — Chemotherapy may be added following surgery.
  • Stage IV — Treatment may include the following:
    • Surgery to remove the cancer, along with the tissue around the cancer. The surgeon will then sew the remaining parts back together and remove parts of other organs to which the cancer has spread.
    • Chemotherapy (“chemo”) is used to shrink the tumor before surgery and to treat any remaining cancer. Chemo uses powerful medicines to kill cancer cells or stop them from growing (dividing) and making more cancer cells.
  • Recurrent Disease — (disease that returns) Treatment may include the following:
    • Surgery to remove the cancer and to remove parts of other organs where the cancer has spread.
    • Radiation (high-energy X-rays or other types of radiation used to kill cancer cells or stop them from growing) or chemo to relieve symptoms and improve the patient’s quality of life.

What are the survival rates for colorectal carcinoma?

  • The five-year survival rate for adults is about 90% for stage I, 75% for stage II, 60% for stage III and less-than 10% for stage IV.
  • The rarity of colon cancer in patients less than 20 years old makes it hard to figure survival rates.
  • Most information suggests that younger patients often have stage III or IV disease by the time they are diagnosed.
