pancreas cancer ; Stages Of Cancer Of The Pancreas
Once cancer of the pancreas is found, more tests will be done to find out if the cancer has spread from the pancreas to the tissues around it or to other parts of the body. This is called staging. The following stages are used for cancer of the pancreas:
Stage I Cancer is found only in the pancreas itself, or has started to spread just to the tissues next to the pancreas, such as the small intestine, the stomach, or the bile duct.
Stage II Cancer has spread to nearby organs such as the stomach, spleen, or colon, but has not entered the lymph nodes. (Lymph nodes are small, bean-shaped structures that are found throughout the body; they produce and store infection-fighting cells).
Stage III Cancer has spread to lymph nodes near the pancreas. The cancer may or may not have spread to nearby organs.
Stage IV Cancer has spread to places far away from the pancreas, such as the liver or lungs.
Recurrent Recurrent disease means that the cancer has come back (recurred) after it has been treated. It may come back in the pancreas or in another part of the body.
How Cancer Of The Pancreas Is Treated
There are treatments for all patients with cancer of the pancreas. Three kinds of treatment are used: surgery (taking out the cancer or relieving symptoms caused by the cancer) radiation therapy (using high-dose x-rays or other high-energy rays to kill cancer cells) chemotherapy (using drugs to kill cancer cells).
The use of biological therapy (using the body's immune system to fight cancer) is being tested for pancreatic cancer.
Surgery may be used to take out the tumor. Your doctor may take out the cancer using one of the following operations:
A Whipple procedure removes the head of the pancreas, part of the small intestine, and some of the tissues around it. Enough of the pancreas is left to continue making digestive juices and insulin.
Total pancreatectomy takes out the whole pancreas, part of the small intestine, part of the stomach, the bile duct, the gallbladder, spleen, and most of the lymph nodes in the area.
Distal pancreatectomy takes out only the tail of the pancreas.
If your cancer has spread and it cannot be removed, your doctor may do surgery to relieve symptoms. If the cancer is blocking the small intestine and bile builds up in the gallbladder, your doctor may do surgery to go around (bypass) all or part of the small intestine. During this operation, your doctor will cut the gallbladder or bile duct and sew it to the small intestine. This is called biliary bypass. Surgery or x-ray procedures may also be done to put in a tube (catheter) to drain bile that has built up in the area. During these procedures, your doctor may make the catheter drain through a tube to the outside of the body or the catheter may go around the blocked area and drain the bile to the small intestine. In addition, if the cancer is blocking the flow of food from the stomach, the stomach may be sewn directly to the small intestine so you can continue to eat normally.
Radiation therapy uses high-energy x-rays to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external radiation therapy) or from putting materials that produce radiation (radioisotopes) through thin plastic tubes in the area where the cancer cells are found (internal radiation therapy).
Chemotherapy uses drugs to kill cancer cells. Chemotherapy may be taken by pill, or it may be put into the body by a needle in the vein or muscle. Chemotherapy is called a systemic treatment because the drug enters the bloodstream, travels through the body, and can kill cancer cells outside the pancreas.
Biological therapy tries to get your own body to fight cancer. It uses materials made by your own body or made in a laboratory to boost, direct, or restore your body's natural defenses against disease. Biological therapy is sometimes called biological response modifier (BRM) therapy or immunotherapy. Biological therapy is being tested in clinical trials.
