Pancreatic cancer is a disease in which malignant (cancer) cells form in the tissues of the pancreas.

The pancreas is a gland about 6 inches long that is shaped like a thin pear lying on its side. The wider end of the pancreas is called the head, the middle section is called the body, and the narrow end is called the tail. The pancreas lies between the stomach and the spine.

Anatomy of the pancreas. The pancreas has three areas: head, body, and tail. It is found in the abdomen near the stomach, intestines, and other organs.

The pancreas has two main jobs in the body:

The digestive juices are made by exocrine pancreas cells and the hormones are made by endocrine pancreas cells. About 95% of pancreatic cancers begin in exocrine cells.

This summary is about exocrine pancreatic cancer. For information on endocrine pancreatic cancer, see the PDQ summary on Pancreatic Neuroendocrine Tumors (Islet Cell Tumors) Treatment.

For information on pancreatic cancer in children, see the PDQ summary on Unusual Cancers of Childhood Treatment.

Smoking and health history can affect the risk of pancreatic cancer.

Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn’t mean that you will not get cancer. Talk with your doctor if you think you may be at risk.

Risk factors for pancreatic cancer include the following:

Signs and symptoms of pancreatic cancer include jaundice, pain, and weight loss.

Pancreatic cancer may not cause early signs or symptoms. Signs and symptoms may be caused by pancreatic cancer or by other conditions. Check with your doctor if you have any of the following:

  • Jaundice (yellowing of the skin and whites of the eyes).
  • Light-colored stools.
  • Dark urine.
  • Pain in the upper or middle abdomen and back.
  • Weight loss for no known reason.
  • Loss of appetite.
  • Feeling very tired.

Pancreatic cancer is difficult to detect (find) and diagnose early.

Pancreatic cancer is difficult to detect and diagnose for the following reasons:

  • There aren’t any noticeable signs or symptoms in the early stages of pancreatic cancer.
  • The signs and symptoms of pancreatic cancer, when present, are like the signs and symptoms of many other illnesses.
  • The pancreas is hidden behind other organs such as the stomach, small intestinelivergallbladderspleen, and bile ducts.

Tests that examine the pancreas are used to detect (find), diagnose, and stage pancreatic cancer.

Pancreatic cancer is usually diagnosed with tests and procedures that make pictures of the pancreas and the area around it. The process used to find out if cancer cells have spread within and around the pancreas is called staging. Tests and procedures to detect, diagnose, and stage pancreatic cancer are usually done at the same time. In order to plan treatment, it is important to know the stage of the disease and whether or not the pancreatic cancer can be removed by surgery.

The following tests and procedures may be used:

  • Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
  • Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances, such as bilirubin, released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease.
  • Tumor marker test : A procedure in which a sample of blood, urine, or tissue is checked to measure the amounts of certain substances, such as CA 19-9, and carcinoembryonic antigen (CEA), made by organs, tissues, or tumor cells in the body. Certain substances are linked to specific types of cancer when found in increased levels in the body. These are called tumor markers.
  • MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
  • CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. A spiral or helical CT scan makes a series of very detailed pictures of areas inside the body using an x-ray machine that scans the body in a spiral path.
  • PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. A PET scan and CT scan may be done at the same time. This is called a PET-CT.
  • Abdominal ultrasound : An ultrasound exam used to make pictures of the inside of the abdomen. The ultrasound transducer is pressed against the skin of the abdomen and directs high-energy sound waves (ultrasound) into the abdomen. The sound waves bounce off the internal tissues and organs and make echoes. The transducer receives the echoes and sends them to a computer, which uses the echoes to make pictures called sonograms. The picture can be printed to be looked at later.
  • Endoscopic ultrasound (EUS): A procedure in which an endoscope is inserted into the body, usually through the mouth or rectum. An endoscope is a thin, tube-like instrument with a light and a lens for viewing. A probe at the end of the endoscope is used to bounce high-energy sound waves (ultrasound) off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. This procedure is also called endosonography.
  • Endoscopic retrograde cholangiopancreatography (ERCP): A procedure used to x-ray the ducts (tubes) that carry bile from the liver to the gallbladder and from the gallbladder to the small intestine. Sometimes pancreatic cancer causes these ducts to narrow and block or slow the flow of bile, causing jaundice. An endoscope (a thin, lighted tube) is passed through the mouth, esophagus, and stomach into the first part of the small intestine. A catheter (a smaller tube) is then inserted through the endoscope into the pancreatic ducts. A dye is injected through the catheter into the ducts and an x-ray is taken. If the ducts are blocked by a tumor, a fine tube may be inserted into the duct to unblock it. This tube (or stent) may be left in place to keep the duct open. Tissue samples may also be taken.
  • Percutaneous transhepatic cholangiography (PTC): A procedure used to x-ray the liver and bile ducts. A thin needle is inserted through the skin below the ribs and into the liver. Dye is injected into the liver or bile ducts and an x-ray is taken. If a blockage is found, a thin, flexible tube called a stent is sometimes left in the liver to drain bile into the small intestine or a collection bag outside the body. This test is done only if ERCPcannot be done.
  • Laparoscopy : A surgical procedure to look at the organs inside the abdomen to check for signs of disease. Small incisions (cuts) are made in the wall of the abdomen and a laparoscope (a thin, lighted tube) is inserted into one of the incisions. The laparoscope may have an ultrasound probe at the end in order to bounce high-energy sound waves off internal organs, such as the pancreas. This is called laparoscopic ultrasound. Other instruments may be inserted through the same or other incisions to perform procedures such as taking tissue samples from the pancreas or a sample of fluid from the abdomen to check for cancer.
  • Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. There are several ways to do a biopsy for pancreatic cancer. A fine needle or a core needle may be inserted into the pancreas during an x-ray or ultrasound to remove cells. Tissue may also be removed during a laparoscopy.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) and treatment options depend on the following:

  • Whether or not the tumor can be removed by surgery.
  • The stage of the cancer (the size of the tumor and whether the cancer has spread outside the pancreas to nearby tissues or lymph nodes or to other places in the body).
  • The patient’s general health.
  • Whether the cancer has just been diagnosed or has recurred (come back).

Pancreatic cancer can be controlled only if it is found before it has spread, when it can be completely removed by surgery. If the cancer has spread, palliative treatment can improve the patient’s quality of life by controlling the symptoms and complications of this disease.

Stages of Pancreatic Cancer

KEY POINTS

  • Tests and procedures to stage pancreatic cancer are usually done at the same time as diagnosis.
  • There are three ways that cancer spreads in the body.
  • Cancer may spread from where it began to other parts of the body.
  • The following stages are used for pancreatic cancer:
    • Stage 0 (Carcinoma in Situ)
    • Stage I
    • Stage II
    • Stage III
    • Stage IV

Tests and procedures to stage pancreatic cancer are usually done at the same time as diagnosis.

The process used to find out if cancer has spread within the pancreas or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage of the disease in order to plan treatment. The results of some of the tests used to diagnose pancreatic cancer are often also used to stage the disease. See the General Information section for more information.

There are three ways that cancer spreads in the body.

Cancer can spread through tissue, the lymph system, and the blood:

  • Tissue. The cancer spreads from where it began by growing into nearby areas.
  • Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
  • Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.

Cancer may spread from where it began to other parts of the body.

When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.

  • Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body.
  • Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body.

The metastatic tumor is the same type of cancer as the primary tumor. For example, if pancreatic cancer spreads to the liver, the cancer cells in the liver are actually pancreatic cancer cells. The disease is metastatic pancreatic cancer, not liver cancer.

The following stages are used for pancreatic cancer:

Stage 0 (Carcinoma in Situ)

In stage 0abnormal cells are found in the lining of the pancreas. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ.

Stage I

ENLARGEStage I pancreatic cancer; drawing on the left shows that stage IA pancreatic cancer is smaller than 2 centimeters. The drawing on the right shows that stage IB pancreatic cancer is larger than 2 centimeters. An inset shows that a 2 centimeter tumor is about the size of a peanut. The duodenum is also shown.
Stage I pancreatic cancer. In stage IA, the tumor is 2 centimeters or smaller. In stage IB, the tumor is larger than 2 centimeters.

In stage Icancer has formed and is found in the pancreas only. Stage I is divided into stage IA and stage IB, based on the size of the tumor.

Stage II

In stage IIcancer may have spread to nearby tissue and organs, and may have spread to lymph nodes near the pancreas. Stage II is divided into stage IIA and stage IIB, based on where the cancer has spread.

  • Stage IIA: Cancer has spread to nearby tissue and organs but has not spread to nearby lymph nodes.

Stage III pancreatic cancer. Cancer has spread to the major blood vessels near the pancreas. These include the superior mesenteric artery, celiac axis, common hepatic artery, and portal vein. Cancer may have spread to nearby lymph nodes.

In stage IIIcancer has spread to the major blood vessels near the pancreas and may have spread to nearby lymph nodes.

Stage IV

ENLARGEStage IV pancreatic cancer; drawing shows other parts of the body where pancreatic cancer may spread, including the lung, liver, and peritoneal cavity. An inset shows cancer cells spreading from the pancreas, through the blood and lymph system, to another part of the body where metastatic cancer has formed.
Stage IV pancreatic cancer. Cancer may be any size and has spread to other parts of the body, such as the lung, liver, and peritoneal cavity (the space in the abdomen that contains the intestines, stomach, and liver). Cancer may also have spread to tissues and organs near the pancreas or to lymph nodes.

In stage IVcancer may be of any size and has spread to distant organs, such as the liverlung, and peritoneal cavity. It may have also spread to organs and tissues near the pancreas or to lymph nodes.

Recurrent Pancreatic Cancer

Recurrent pancreatic cancer is cancer that has recurred (come back) after it has been treated. The cancer may come back in the pancreas or in other parts of the body.

Treatment Option Overview

  • There are different types of treatment for patients with pancreatic cancer.
  • Five types of standard treatment are used:
    • Surgery
    • Radiation therapy
    • Chemotherapy
    • Chemoradiation therapy
    • Targeted therapy
  • There are treatments for pain caused by pancreatic cancer.
  • Patients with pancreatic cancer have special nutritional needs.
  • New types of treatment are being tested in clinical trials.
    • Biologic therapy
  • Patients may want to think about taking part in a clinical trial.
  • Patients can enter clinical trials before, during, or after starting their cancer treatment.
  • Follow-up tests may be needed

There are different types of treatment for patients with pancreatic cancer.

Different types of treatment are available for patients with pancreatic cancer. Some treatments are standard(the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

Five types of standard treatment are used:

Surgery

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

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

  • 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

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy:

The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat pancreatic cancer.

Chemotherapy

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them 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 into the cerebrospinal fluid, an organ, or a body cavitysuch as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). Combination chemotherapy is treatment using more than one anticancer drug. The way the chemotherapy is given depends on the type and stage of the cancer being treated.

See Drugs Approved for Pancreatic Cancer for more information.

Chemoradiation therapy

Chemoradiation therapy combines chemotherapy and radiation therapy to increase the effects of both.

Targeted therapy

Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Tyrosine kinase inhibitors (TKIs) are targeted therapy drugs that block signals needed for tumors to grow. Erlotinib is a type of TKI used to treat pancreatic cancer.

See Drugs Approved for Pancreatic Cancer for more information.

There are treatments for pain caused by pancreatic cancer.

Pain can occur when the tumor presses on nerves or other organs near the pancreas. When pain medicine is not enough, there are treatments that act on nerves in the abdomen to relieve the pain. The doctor may inject medicine into the area around affected nerves or may cut the nerves to block the feeling of pain. Radiation therapy with or without chemotherapy can also help relieve pain by shrinking the tumor. See the PDQsummary on Cancer Pain for more information.

Patients with pancreatic cancer have special nutritional needs.

Surgery to remove the pancreas may affect its ability to make pancreatic enzymes that help to digest food. As a result, patients may have problems digesting food and absorbing nutrients into the body. To prevent malnutrition, the doctor may prescribe medicines that replace these enzymes. See the PDQ summary on Nutrition in Cancer Care for more information.

New types of treatment are being tested in clinical trials.

This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website.

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.

Patients may want to think about taking part in a clinical trial.

For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.

Many of today’s standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.

Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.

Patients can enter clinical trials before, during, or after starting their cancer treatment.

Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.

Clinical trials are taking place in many parts of the country. Information about clinical trials supported by NCI can be found on NCI’s clinical trials search webpage. Clinical trials supported by other organizations can be found on the ClinicalTrials.gov website.

Follow-up tests may be needed

Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.

Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
