Surgery
Surgery to remove cancer may be used to treat
metastatic or recurrent colorectal cancer. The type of
surgery chosen depends upon the
stage
of the cancer.
Surgery Choices
Surgical options include:
- Bowel resection. This operation
involves cutting into the abdomen to reach the area of the colon or rectum that
is affected by the cancer. The surgeon cuts out the cancer as well as the parts
of the colon or rectum that are next to it. Then the two healthy ends of the
colon or rectum are sewn back together.
- Liver resection. In this operation the surgeon cuts
out cancer that has spread to the liver, as well as parts of the liver that are
next to the cancer. Up to half of your liver can be removed as long as the rest
is healthy. Two other methods to destroy cancer cells in the liver include
radio waves (radiofrequency ablation) and heat (microwave
coagulation).
- Cryosurgery. Also called cryotherapy, this type of
surgery uses liquid nitrogen to freeze and destroy colorectal cancer that has
spread to the liver. It is used when the tumors in the liver are still fairly
small.
If cancer that has returned to your intestine is large, more of
your colon or rectum may have to be removed. The ends of your colon or rectum
are rejoined during surgery. If they can't be rejoined, you may need a
colostomy. Most people do not need a permanent
colostomy.

When cancer has spread to other parts of the body, the kind of
surgery you will need depends on where the cancer is and how big the tumor is.
Sometimes surgery is used not to cure your cancer but to make your life more
comfortable. If a tumor is blocking your colon, for example, the surgeon may
remove it to allow your intestine to work normally. If advanced cancer is
blocking your rectum, your doctor may place an expandable tube, called a stent,
in the rectum to unblock it.
What To Think About
Surgery may be used to remove metastatic or recurrent colorectal
cancer that is confined to the colon or that has spread to the liver, lungs, or
ovaries. Surgery does not usually cure metastatic or recurrent colorectal
cancer, but it may relieve pain and discomfort, slow the spread of the disease,
and help you live longer.
