Pancreatic cancer treatments

At the time of diagnosis, only about 20% of pancreatic tumors can be removed by surgery. The standard procedure is called a pancreaticoduodenectomy (Whipple procedure).

This surgery for pancreatic cancer should be done at centers that perform the procedure frequently. Some studies suggest that surgery is best performed at hospitals that perform at least 9 of these surgeries per year.

When the tumor is confined to the pancreas but cannot be removed, a combination of radiation therapy and chemotherapy may be recommended. When the tumor has spread to other organs (metastasized) such as the liver, chemotherapy alone is usually used. The standard chemotherapy agent is gemcitabine, but other drugs may be used. Gemcitabine provides clinical improvement in approximately 25% of patients.

For patients who have biliary obstruction (blockage of the vessels that transport bile) and the tumor cannot be totally removed, the obstruction must be relieved. There are generally two approaches to this, surgery and placement of a biliary stent (similar to stents placed in the arteries of the heart to relieve blockages) during ERCP.

Management of pain and other symptoms is an important part of the treatment of advanced pancreatic cancer. Hospice can be very helpful to patients for both pain and symptom management and psychological support for the patient and the family during the course of the illness.

More detailed information about pancreatic cancer treatments

Three types of standard treatment are used for pancreatic cancer.

Surgery

One of the following types of surgery may be used to take out the tumor:

  • Whipple procedure: A surgical procedure in which the head of the pancreas, the gallbladder, part of the stomach, part of the small intestine, and the bile duct are removed. Enough of the pancreas is left to produce digestive juices and insulin.
  • Total pancreatectomy: This operation removes the whole pancreas, part of the stomach, part of the small intestine, the common bile duct, the gallbladder, the spleen, and nearby lymph nodes.
  • Distal pancreatectomy: The body and the tail of the pancreas and usually the spleen are removed.

If the cancer has spread and cannot be removed, the following types of palliative surgery may be done to relieve symptoms:

  • Surgical biliary bypass: If cancer is blocking the small intestine and bile is building up in the gallbladder, a biliary bypass may be done. During this operation, the doctor will cut the gallbladder or bile duct and sew it to the small intestine to create a new pathway around the blocked area.
  • Endoscopic stent placement: If the tumor is blocking the bile duct, surgery may be done to put in a stent (a thin tube) to drain bile that has built up in the area. The doctor may place the stent through a catheter that drains to the outside of the body or the stent may go around the blocked area and drain the bile into the small intestine.
  • Gastric bypass: If the tumor is blocking the flow of food from the stomach, the stomach may be sewn directly to the small intestine so the patient can continue to eat normally.

Radiation therapy as  pancreatic cancer treatment

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a  radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated.

Chemotherapy for pancreatic cancer treatment

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly in the spinal column, a body cavity such as the abdomen, or an organ, the drugs mainly affect cancer cells in those areas. The way the chemotherapy is given depends on the type and stage of the cancer being treated.

Other types of treatment are being tested in clinical trials.

Biologic therapy

Biologic therapy is a treatment that uses the patient’s immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body’s natural defenses against cancer. This type of cancer treatment is also called biotherapy or immunotherapy.
