Pancreatic Cancer Early Detection, Diagnosis, and Staging
Pancreatic Cancer Early Detection, Diagnosis, and Staging
Pancreatic Cancer Early Detection, Diagnosis, and Staging
Catching cancer early often allows for more treatment options. Some early cancers
may have signs and symptoms that can be noticed, but that is not always the case.
After a cancer diagnosis, staging provides important information about the extent of
cancer in the body and anticipated response to treatment.
Here are some questions you can ask your cancer care team to help you better
understand your cancer diagnosis and treatment options.
● What Should You Ask Your Health Care Team About Pancreatic Cancer?
Screening tests or exams are used to look for a disease in people who have no
symptoms (and who have not had that disease before). At this time, no major
professional groups recommend routine screening for pancreatic cancer in people who
are at average risk. This is because no screening test has been shown to lower the risk
of dying from this cancer.
Sometimes when a person has pancreatic cancer, the levels of certain proteins in the
blood go up. These proteins, called tumor markers, can be detected with blood tests.
The tumor markers CA 19-9 and carcinoembryonic antigen (CEA) are the ones most
closely tied to pancreatic cancer. But these proteins don’t always go up when a person
has pancreatic cancer, and even if they do, the cancer is often already advanced by the
time this happens. Sometimes levels of these tumor markers can go up even when a
person doesn’t have pancreatic cancer. For these reasons, blood tests aren’t used to
screen for pancreatic cancer, although a doctor might still order these tests if a person
has symptoms that might be from pancreatic cancer. These tests are more often used in
people already diagnosed with pancreatic cancer to help tell if treatment is working or if
the cancer is progressing.
Some of the gene changes that increase pancreatic cancer risk can be tested for.
Knowing if you are at increased risk can help you and your doctor decide if you should
have tests to look for pancreatic cancer early, when it might be easier to treat. But
determining whether you might be at increased risk is not simple. Talking to someone
with experience in hereditary cancer syndromes such as a genetic counselor, geneticist,
or an oncologist (doctor who treats people with cancer) is often helpful.
The American Cancer Society strongly recommends that anyone thinking about genetic
testing talk with a genetic counselor, nurse, or doctor qualified to interpret and explain
the test results before they proceed with testing. It’s important to understand what the
tests can and can’t tell you, and what any results might mean, before deciding to be
tested.
Genetic tests look for mutations in your genes that cause inherited conditions. The tests
are used to look for these inherited conditions, not pancreatic cancer itself. Your risk
may be increased if you have one of these conditions, but it doesn’t mean that you have
(or definitely will get) pancreatic cancer.
Doctors are also studying other new tests to try to find pancreatic cancer early.
Interested families at high risk may wish to take part in studies of these new screening
tests

Having one or more of the symptoms below does not mean you have pancreatic cancer.
In fact, many of these symptoms are more likely to be caused by other conditions. Still,
if you have any of these symptoms, it’s important to have them checked by a doctor so
that the cause can be found and treated, if needed.
Signs and symptoms of exocrine pancreatic cancer
Early pancreatic cancers often do not cause any signs or symptoms. By the time they
do cause symptoms, they have often already spread outside the pancreas.
Jaundice is yellowing of the eyes and skin. Most people with pancreatic cancer (and
nearly all people with ampullary cancer) will have jaundice as one of their first
symptoms.
Cancers that start in the head of the pancreas are near the common bile duct. These
cancers can press on the duct and cause jaundice while they are still fairly small, which
can sometimes lead to these tumors being found at an early stage. But cancers that
start in the body or tail of the pancreas don’t press on the duct until they have spread
through the pancreas. By this time, the cancer has often spread beyond the pancreas
as well.
When pancreatic cancer spreads, it often goes to the liver. This can also lead to
jaundice.
Dark urine: Sometimes, the first sign of jaundice is darker urine. As bilirubin levels in
the blood increase, the urine becomes brown in color.
Light-colored or greasy stools: Bilirubin normally helps give stools their brown color.
If the bile duct is blocked, stools might be pale or gray. Also, if bile and pancreatic
enzymes can’t get through to the intestines to help break down fats, the stools can
become greasy and might float in the toilet.
Itchy skin: When bilirubin builds up in the skin, it can start to itch as well as turning
yellow.
Pancreatic cancer is not the most common cause of jaundice. Other causes, such as
gallstones, hepatitis, and other liver and bile duct diseases, are much more common.
Belly or back pain
Pain in the abdomen (belly) or back is common in pancreatic cancer. Cancers that start
in the body or tail of the pancreas can grow fairly large and start to press on other
nearby organs, causing pain. The cancer may also spread to the nerves surrounding
the pancreas, which often causes back pain. Of course, pain in the abdomen or back is
fairly common and is most often caused by something other than pancreatic cancer.
Unintended weight loss is very common in people with pancreatic cancer. These people
often have little or no appetite.
If the cancer presses on the far end of the stomach it can partly block it, making it hard
for food to get through. This can cause nausea, vomiting, and pain that tend to be worse
after eating.
If the cancer blocks the bile duct, bile can build up in the gallbladder, making it larger.
Sometimes a doctor can feel this (as a large lump under the right side of the ribcage)
during a physical exam. It can also be seen on imaging tests.
Pancreatic cancer can also sometimes enlarge the liver, especially if the cancer has
spread to the liver. The doctor might be able to feel this below the right ribcage as well
on an exam, or it might be seen on imaging tests.
Blood clots
Sometimes, the first clue that someone has pancreatic cancer is a blood clot in a large
vein, often in the leg. This is called a deep vein thrombosis or DVT. Symptoms can
include pain, swelling, redness, and warmth in the affected leg. Sometimes a piece of
the clot can break off and travel to the lungs, which might make it hard to breathe or
cause chest pain. A blood clot in the lungs is called a pulmonary embolism or PE.
Still, having a blood clot does not usually mean that you have cancer. Most blood clots
are caused by other things.
Fatty tissue abnormalities
Some people with pancreatic cancer develop an uneven texture of the fatty tissue
underneath the skin. This is caused by the release of the pancreatic enzymes that
digest fat.
Diabetes
Rarely, pancreatic cancers cause diabetes (high blood sugar) because they destroy the
insulin-making cells. Symptoms can include feeling thirsty and hungry, and having to
urinate often. More often, cancer can lead to small changes in blood sugar levels that
don’t cause symptoms of diabetes but can still be detected with blood tests.
Gastrinomas
These tumors make gastrin, a hormone that tells the stomach to make more acid. Too
much gastrin causes a condition known as Zollinger-Ellison syndrome, in which the
stomach makes too much acid. This leads to stomach ulcers, which can cause pain,
nausea, and loss of appetite. Severe ulcers can start bleeding. If the bleeding is mild, it
can lead to anemia (too few red blood cells), which can cause symptoms like feeling
tired and being short of breath. If the bleeding is more severe, it can make stool black
and tarry. Severe bleeding can itself be life-threatening.
If the stomach acid reaches the small intestine, it can damage the cells of the intestinal
lining and break down digestive enzymes before they have a chance to digest food.
This can cause diarrhea and weight loss.
Glucagonomas
These tumors make glucagon, a hormone that increases glucose (sugar) levels in the
blood. Most of the symptoms that can be caused by a glucagonoma are mild and are
more often caused by something else.
Excess glucagon can raise blood sugar, sometimes leading to diabetes. This can cause
symptoms such as feeling thirsty and hungry, and having to urinate often.
People with these tumors can also have problems with diarrhea, weight loss, and
malnutrition. The nutrition problems can lead to symptoms like irritation of the tongue
and the corners of the mouth.
The symptom that brings most people with glucagonomas to their doctor is a rash called
necrolytic migratory erythema. This is a red rash with swelling and blisters that often
travels from place to place on the skin.
Insulinomas
These tumors make insulin, which lowers blood glucose levels. Too much insulin leads
to low blood sugar, which can cause symptoms like weakness, confusion, sweating, and
rapid heartbeat. When blood sugar gets very low, it can lead to a person passing out or
even going into a coma and having seizures.
Somatostatinomas
These tumors make somatostatin, which helps regulate other hormones. Symptoms of
this type of tumor can include belly pain, nausea, poor appetite, weight loss, diarrhea,
symptoms of diabetes (feeling thirsty and hungry, and having to urinate often), and
jaundice (yellowing of the skin and eyes).
The early symptoms of a somatostatinoma tend to be mild and are more often caused
by other things, so these tumors tend to be diagnosed at an advanced stage. Often,
they are not found until they spread to the liver, when they cause problems like jaundice
and pain.
VIPomas
These tumors make a substance called vasoactive intestinal peptide (VIP). Too much
VIP can lead to problems with diarrhea. This may be mild at first, but gets worse over
time. By the time they are diagnosed, most people have severe, watery diarrhea.
Other symptoms can include nausea, vomiting, muscle cramps, feeling weak or tired,
and flushing (redness and warmth in the face or neck).
People with these tumors also tend to have low levels of acid in their stomachs, which
can lead to problems digesting food.
PPomas
These tumors make pancreatic polypeptide (PP), which helps regulate both the
exocrine and endocrine pancreas. They can cause problems such as belly pain and an
enlarged liver. Some people also get watery diarrhea.
Carcinoid tumors
These tumors often make serotonin or its precursor, 5-HTP. When a pancreatic tumor
makes these substances, they first travel to the liver. The liver breaks these substances
down before they can reach the rest of the body and cause problems. Because of this,
carcinoid tumors often don’t cause symptoms until they spread outside the pancreas.
When these tumors do spread, it is most often to the liver. There, the cancer cells can
release hormones directly into the blood leaving the liver. This can cause the carcinoid
syndrome, with symptoms including flushing (redness and warmth in the face or neck),
diarrhea, wheezing, and a rapid heart rate. These symptoms often occur in episodes,
between which the person may feel fine.
Over a long time, the hormone-like substances released by these tumors can damage
heart valves, causing shortness of breath, weakness, and a heart murmur (an abnormal
heart sound).
These tumors don’t make excess hormones, so they don’t cause symptoms in early
stages and often grow quite large before they are found. Most of these are cancers and
start to cause problems as they get larger or spread outside the pancreas. Symptoms
can be like those from exocrine pancreas cancers, including jaundice (yellowing of the
eyes and skin), belly pain, and weight loss.
When pancreatic NETs spread, most often they go to the liver. This can enlarge the
liver, which can cause pain and loss of appetite. It can also affect liver function,
sometimes leading to jaundice (yellowing of the skin and eyes) and abnormal blood
tests.
These cancers can also spread to other organs and tissues. The symptoms depend on
where the cancer is growing. For example, cancer spread to the lungs can cause
shortness of breath or a cough. Spread to bones can cause pain in those bones.

Your doctor will also examine you to look for signs of pancreatic cancer or other health
problems. The exam will probably focus mostly on your belly. Pancreatic cancers can
sometimes cause the liver or gallbladder to swell, which the doctor might be able to feel
during the exam. Your skin and the whites of your eyes will also be checked for jaundice
(yellowing).
If the results of the exam are abnormal, your doctor will probably order tests to help find
the problem. You might also be referred to a gastroenterologist (a doctor who treats
digestive system diseases) for further tests and treatment.
Imaging tests
Imaging tests use x-rays, magnetic fields, sound waves, or radioactive substances to
create pictures of the inside of your body. Imaging tests might be done for a number of
reasons both before and after a diagnosis of pancreatic cancer, including:
The CT scan makes detailed cross-sectional images of your body. CT scans are often
used to diagnose pancreatic cancer because they can show the pancreas fairly clearly.
They can also help show if cancer has spread to organs near the pancreas, as well as
to lymph nodes and distant organs. A CT scan can help determine if surgery might be a
good treatment option.
If your doctor thinks you might have pancreatic cancer, you might get a special type of
CT known as a multiphase CT scan or a pancreatic protocol CT scan. During this
test, different sets of CT scans are taken over several minutes after you get an injection
of an intravenous (IV) contrast.
CT-guided needle biopsy: CT scans can also be used to guide a biopsy needle into a
suspected pancreatic tumor. But if a needle biopsy is needed, most doctors prefer to
use endoscopic ultrasound (described below) to guide the needle into place.
MRI scans use radio waves and strong magnets instead of x-rays to create detailed
images of parts of your body. Most doctors prefer to look at the pancreas with CT
scans, but an MRI might also be done.
Special types of MRI scans can also be used in people who might have pancreatic
cancer:
Ultrasound tests use sound waves to create images of organs such as the pancreas.
Abdominal ultrasound: For this test, a wand-shaped probe is moved over the skin of
the abdomen. It gives off sound waves and detects the echoes as they bounce off
organs. If it’s not clear what might be causing a person’s abdominal symptoms, this
might be the first test done because it is easy to do and it doesn’t expose a person to
radiation. But if signs and symptoms are more likely to be caused by pancreatic cancer,
a CT scan is often more useful.
Endoscopic ultrasound (EUS): This test is more accurate than abdominal ultrasound
and can be very helpful in diagnosing pancreatic cancer. This test is done with a small
ultrasound probe on the tip of an endoscope, which is a thin, flexible tube that doctors
use to look inside the digestive tract.
For this test, you will first be sedated (given medicine to make you sleepy). The scope is
then passed through your mouth or nose, down through the stomach, and into the first
part of the small intestine. It is then pointed toward the pancreas, which is next to the
small intestine. The probe on the tip of the endoscope can get very close to the
pancreas, so this is a very good way to look at the pancreas. If a tumor is seen, a small,
hollow needle can be passed down the endoscope to get biopsy samples of it.
Cholangiopancreatography
This is an imaging test that looks at the pancreatic ducts and bile ducts to see if they are
blocked, narrowed, or dilated. These tests can help show if someone might have a
pancreatic tumor that is blocking a duct. They can also be used to help plan surgery.
The test can be done in different ways, each of which has pros and cons.
The doctor can see through the endoscope to find the ampulla of Vater (where the
common bile duct empties into the small intestine). The doctor guides a catheter (a very
small tube) through the tip of the endoscope and into the common bile duct. A small
amount of dye (contrast material) is then injected into the common bile duct, and x-rays
are taken. This dye outlines the bile and pancreatic ducts. The x-rays can show
narrowing or blockage in these ducts that might be due to pancreatic cancer. The doctor
doing this test can also put a small brush through the tube to remove cells for a biopsy
(see below).
ERCP can also be used to place a stent (small tube) into a bile or pancreatic duct to
keep it open if a nearby tumor is pressing on it. This is described in more detail in the
section on palliative surgery in Surgery for pancreatic cancer.
This test, also known as OctreoScan, can be very helpful in finding pancreatic
neuroendocrine tumors (NETs). A hormone-like substance called octreotide that is
bound to a radioactive substance is injected into a vein. Octreotide travels through the
blood and attaches to the tumor cells of many types of NETs (although it is less helpful
for insulinomas).
Several hours after the injection, a special camera can be used to show where the
radioactivity is in the body. More scans may be done on the following few days as well.
This scan can also help decide on treatment. NETs that show up on SRS scans will
often stop growing if treated with octreotide.
For a PET scan, you are injected with a slightly radioactive form of sugar, which collects
mainly in cancer cells. A special camera is then used to create a picture of areas of
radioactivity in the body.
This test is sometimes used to look for spread from exocrine pancreatic cancers, but
because NETs grow slowly, they do not show up well on PET scans.
PET/CT scan: Special machines can do both a PET and CT scan at the same time.
This lets the doctor compare areas of higher radioactivity on the PET scan with the
more detailed appearance of that area on the CT scan. This test can help determine the
stage (extent) of the cancer. It might be especially useful for spotting cancer that has
spread beyond the pancreas and wouldn’t be treatable by surgery.
Angiography
This is an x-ray test that looks at blood vessels. A small amount of contrast dye is
injected into an artery to outline the blood vessels, and then x-rays are taken.
Angiography can also be used to look for pancreatic NETs that are too small to be seen
on other imaging tests. These tumors cause the body to make more blood vessels to
“feed” the tumor, which can often be seen on angiography.
X-ray angiography can be uncomfortable because the doctor has to put a small catheter
into the artery leading to the pancreas. Usually the catheter is put into an artery in your
inner thigh and threaded up to the pancreas. A local anesthetic is often used to numb
the area before inserting the catheter. Once the catheter is in place, the dye is injected
to outline all the vessels while the x-rays are being taken.
Angiography can also be done with a CT scanner (CT angiography) or an MRI scanner
(MR angiography). These techniques are now used more often because they can give
the same information without the need for a catheter in the artery. You might still need
an IV line so that a contrast dye can be injected into the bloodstream during the
imaging.
Blood tests
Several types of blood tests can be used to help diagnose pancreatic cancer or to help
determine treatment options if it is found.
Liver function tests: Jaundice (yellowing of the skin and eyes) is often one of the first
signs of pancreatic cancer, but it can have many causes other than cancer. Doctors
often get blood tests to assess liver function in people with jaundice to help determine
its cause.
For example, blood tests that look at levels of different kinds of bilirubin (a chemical
made by the liver) can help tell whether a patient’s jaundice is caused by disease in the
liver itself or by a blockage of bile flow (from a gallstone, a tumor, or other disease).
Tumor markers: Tumor markers are substances that can sometimes be found in the
blood when a person has cancer. Two tumor markers may be helpful in pancreatic
cancer:
● CA 19-9
● Carcinoembryonic antigen (CEA), which is not used as often as CA 19-9
Neither of these tumor marker tests is accurate enough to tell for sure if someone has
pancreatic cancer. Levels of these tumor markers are not high in all people with
pancreatic cancer, and some people who don’t have pancreatic cancer might have high
levels of these markers for other reasons. Still, these tests can sometimes be helpful,
along with other tests, in figuring out if someone has cancer.
In people already known to have pancreatic cancer and who have high CA19-9 or CEA
levels, these levels can be measured over time to help tell how well treatment is
working. If all of the cancer has been removed, these tests can also be done to look for
the cancer coming back.
Other blood tests: Other tests can help evaluate a person’s general health (such as
kidney and bone marrow function). These tests can help determine if they’ll be able to
withstand the stress of a major operation.
Blood tests looking at the levels of certain pancreatic hormones can often help diagnose
pancreatic neuroendocrine tumors (NETs). Tests might be done to check blood levels
of:
● Hormones made by different types of NET cells, such as insulin, gastrin, glucagon,
somatostatin, pancreatic polypeptide, and VIP (vasoactive intestinal peptide)
● Chromogranin A (CgA)
● Glucose and C-peptide (for insulinomas)
Carcinoid tumors: For carcinoids, a blood test may be done to look for serotonin,
which is made by many of these tumors. The urine might also be tested for serotonin
and for related chemicals such as 5-HIAA and 5-HTP.
Other common tests to look for carcinoids include blood tests for chromogranin A (CgA),
neuron-specific enolase (NSE), substance P, and gastrin.
Depending on where the tumor might be located and the patient’s symptoms, doctors
might do other blood tests as well.
Biopsy
A person’s medical history, physical exam, and imaging test results may strongly
suggest pancreatic cancer, but usually the only way to be sure is to remove a small
sample of tumor and look at it under the microscope. This procedure is called a biopsy.
Biopsies can be done in different ways.
Percutaneous (through the skin) biopsy: For this test, a doctor inserts a thin, hollow
needle through the skin over the abdomen and into the pancreas to remove a small
piece of a tumor. This is known as a fine needle aspiration (FNA). The doctor guides the
needle into place using images from ultrasound or CT scans.
Endoscopic biopsy: Doctors can also biopsy a tumor during an endoscopy. The doctor
passes an endoscope (a thin, flexible, tube with a small video camera on the end) down
the throat and into the small intestine near the pancreas. At this point, the doctor can
either use endoscopic ultrasound (EUS) to pass a needle into the tumor or endoscopic
retrograde cholangiopancreatography (ERCP) to remove cells from the bile or
pancreatic ducts. These tests are described in more detail above. You will be sedated
(made sleepy) for these tests, but general anesthesia (being put into a deep sleep) is
not usually needed. Major side effects from these types of biopsies are rare.
Surgical biopsy: Surgical biopsies are now done less often than in the past. They can
be useful if the surgeon is concerned the cancer has spread beyond the pancreas and
wants to look at (and possibly biopsy) other organs in the abdomen.
The most common way to do a surgical biopsy is to use laparoscopy (sometimes called
keyhole surgery). You will be sedated or asleep for this procedure. The surgeon makes
several small incisions (cuts) in the abdomen and inserts long, thin instruments. One of
these has a small video camera on the end to let the surgeon see inside the abdomen.
The surgeon can look at the pancreas and other organs for tumors and take biopsy
samples of abnormal areas.
In the past, surgeons often used a laparotomy (a large incision through the skin into the
wall of the abdomen) to examine internal organs and take biopsies. But this type of
surgery requires a longer recovery and is now rarely used.
Rarely, the doctor might not do a biopsy on someone who has a tumor in the pancreas
if imaging tests show the tumor is very likely to be cancer and if it looks like surgery can
remove all of it. Instead, the doctor will proceed with surgery, at which time the tumor
cells can be looked at to confirm the diagnosis. During surgery, if the doctor finds that
the cancer has spread too far to be removed completely, only a sample of the cancer
may be removed to confirm the diagnosis, and the rest of the planned operation will be
stopped.
See Testing Biopsy and Cytology Specimens for Cancer to learn more about different
types of biopsies, how the biopsy samples are tested in the lab, and what the results will
tell you.

The earliest stage pancreas cancers are stage 0 (carcinoma in situ), and then range
from stages I (1) through IV (4). As a rule, the lower the number, the less the cancer has
spread. A higher number, such as stage IV, means a more advanced cancer. Cancers
with similar stages tend to have a similar outlook and are often treated in much the
same way.
● The extent of the tumor (T): How large is the tumor and has it grown outside the
pancreas into nearby blood vessels?
● The spread to nearby lymph nodes (N): Has the cancer spread to nearby lymph
nodes? If so, how many of the lymph nodes have cancer?
● The spread (metastasized) to distant sites (M): Has the cancer spread to distant
lymph nodes or distant organs such as the liver, peritoneum (the lining of the
abdominal cavity), lungs or bones?
The system described below is the most recent AJCC system, effective January 2018. It
is used to stage most pancreatic cancers except for well-differentiated pancreatic
neuroendocrine tumors (NETs), which have their own staging system.
The staging system in the table uses the pathologic stage. It is determined by
examining tissue removed during an operation. This is also known as the surgical stage.
Sometimes, if the doctor's physical exam, imaging, or other tests show the tumor is too
large or has spread to nearby organs and cannot be removed by surgery right away or
at all, radiation or chemotherapy might be given first. In this case, the cancer will have a
clinical stage. It is based on the results of physical exam, biopsy, and imaging tests
(see Tests for Pancreatic Cancer). The clinical stage can be used to help plan
treatment. Sometimes, though, the cancer has spread further than the clinical stage
estimates, and may not predict the patient’s outlook as accurately as a pathologic stage.
For more information, see Cancer Staging.
Numbers or letters after T, N, and M provide more details about each of these factors.
Higher numbers mean the cancer is more advanced. Once a person’s T, N, and M
categories have been determined, this information is combined in a process called
stage grouping to assign an overall stage.
Cancer staging can be complex. If you have any questions about your stage, please ask
your doctor to explain it to you in a way you understand. (Additional information of the
TNM system also follows the stage table below.)
* The following additional categories are not listed on the table above:
Tumor grade
The grade describes how closely the cancer looks like normal tissue under a
microscope.
●Grade 1 (G1) means the cancer looks much like normal pancreas tissue.
●Grade 3 (G3) means the cancer looks very abnormal.
●Grade 2 (G2) falls somewhere in between.
Low-grade cancers (G1) tend to grow and spread more slowly than high-grade (G3)
cancers. Most of the time, Grade 3 pancreas cancers tend to have a poor prognosis
(outlook) compared to Grade 1 or 2 cancers.
Extent of resection
For patients who have surgery, another important factor is the extent of the resection —
whether or not all of the tumor is removed:
● R0: All of the cancer is thought to have been removed. (There are no visible or
microscopic signs suggesting that cancer was left behind.)
● R1: All visible tumor was removed, but lab tests of the removed tissue show that
some small areas of cancer were probably left behind.
● R2: Some visible tumor could not be removed.
● Resectable
● Borderline resectable
● Unresectable (either locally advanced or metastatic)
Resectable
If the cancer is only in the pancreas (or has spread just beyond it) and the surgeon
believes the entire tumor can be removed, it is called resectable. (In general, this would
include most stage IA, IB, and IIA cancers in the TNM system.)
It’s important to note that some cancers might appear to be resectable based on
imaging tests, but once surgery is started it might become clear that not all of the cancer
can be removed. If this happens, only some of the cancer may be removed to confirm
the diagnosis (if a biopsy hasn’t been done already), and the rest of the planned
operation will be stopped to help avoid the risk of major side effects.
Borderline resectable
This term is used to describe some cancers that might have just reached nearby blood
vessels, but which the doctors feel might still be removed completely with surgery.
Unresectable
Locally advanced: If the cancer has not yet spread to distant organs but it still can’t be
removed completely with surgery, it is called locally advanced. Often the reason the
cancer can’t be removed is because it has grown into or surrounded nearby major blood
vessels. (This would include some stage III cancers in the TNM system.)
Surgery to try to remove these tumors would be very unlikely to be helpful and could still
have major side effects. Some type of surgery might still be done, but it would be a less
extensive operation with the goal of preventing or relieving symptoms or problems like a
blocked bile duct or intestinal tract, instead of trying to cure the cancer.
Metastatic: If the cancer has spread to distant organs, it is called metastatic (Stage IV).
These cancers can’t be removed completely. Surgery might still be done, but the goal
would be to prevent or relieve symptoms, not to try to cure the cancer.

The stages of pancreatic NET range from I (1) through IV (4). As a rule, the lower the
stage, the less the cancer has spread. A higher number, such as stage IV, means
cancer has spread more. Although each person’s cancer experience is unique, cancers
with similar stages tend to have a similar outlook and are often treated in much the
same way.
● The size and extent of the main tumor (T): How large is the tumor? Has it grown
into nearby structures or organs?
● The spread to nearby lymph nodes (N): Has the cancer spread to nearby lymph
nodes?
● The spread (metastasis) to distant sites (M): Has the cancer spread to distant
organs? (The most common site of spread is the liver.)
Numbers or letters after T, N, and M provide more details about each of these factors.
Higher numbers mean the cancer is more advanced. Once a person’s T, N, and M
categories have been determined, this information is combined in a process called
stage grouping to assign an overall stage. For more information, see Cancer Staging.
The system described below is the most recent version of the AJCC system, effective
as of January 2018. It is used to stage well-differentiated pancreatic NETs, but not high-
grade pancreatic NETs (known as neuroendocrine carcinomas) or other types of
pancreatic cancer, which have their own staging system.
Pancreatic NETs are typically given a clinical stage based on the results of a physical
exam, biopsy, and imaging tests (as described in Tests for Pancreatic Cancer). If
surgery is done, the pathologic stage (also called the surgical stage) is determined by
examining tissue removed during the operation.
Staging for pancreatic NETs can be complex. If you have any questions about the stage
of your cancer or what it means, please ask your doctor to explain it to you in a way you
understand.
* The following additional categories are not listed in the table above:
Tumor grade
The grade describes how quickly the cancer is likely to grow and spread. For pancreatic
NETs, an important part of grading is measuring how many of the cells are in the
process of dividing into new cells. This is determined by:
●The mitotic count, which is the number of cells seen under a microscope that are
in the process of splitting into two new cells (mitosis).
●The Ki-67 index, which is a measure of the portion of cells that are almost ready to
start splitting.
Based on these tests, NETs are divided into 2 main groups:
Tumor functionality
The outlook for pancreatic NETs can be affected by whether the tumor is functioning
(making hormones) or non-functioning. For functioning tumors, the type of hormone can
also be important. For example, insulinomas (NETs that make insulin) tend to have a
lower risk of spreading than other types of NETs.

But remember, the 5-year relative survival rates are estimates – your outlook can vary
based on a number of factors specific to you.
● The numbers below are among the most current available. But to get 5-year
survival rates, doctors have to look at people who were treated at least 5 years ago.
As treatments are improving over time, people who are now being diagnosed with
pancreatic cancer may have a better outlook than these statistics show.
● These statistics are based on the stage of the cancer when it was first diagnosed.
They do not apply to cancers that later come back or spread, for example.
● The outlook for people with pancreatic cancer varies by the stage (extent) of the
cancer – in general, the survival rates are higher for people with earlier stage
cancers. But many other factors can affect a person’s outlook, such as age and
overall health, and how well the cancer responds to treatment. The outlook for each
person is specific to their circumstances.
Your doctor can tell you how these numbers may apply to you, as he or she is familiar
with your particular situation.
● The 5-year survival rate for people with stage IA pancreatic cancer is about 14%.
For stage IB cancer, the 5-year survival rate is about 12%.
● For stage IIA pancreatic cancer, the 5-year survival rate is about 7%. For stage IIB
cancer, the 5-year survival rate is about 5%.
● The 5-year survival rate for stage III pancreatic cancer is about 3%.
● Stage IV pancreatic cancer has a 5-year survival rate of about 1%. Still, there are
often treatment options available for people with this stage of cancer.
Remember, these survival rates are only estimates – they can’t predict what will happen
to any individual person. We understand that these statistics can be confusing and may
lead you to have more questions. Talk to your doctor to better understand your specific
situation.

During treatment
Once treatment begins, you’ll need to know what to expect and what to look for. Not all
of these questions may apply to you, but getting answers to the ones that do may be
helpful.
After treatment
● Are there any limits on what I can do?
● What symptoms should I watch for?
● What kind of exercise should I do now?
● What type of follow-up will I need after treatment?
● How often will I need to have follow-up exams and tests?
● How will we know if the cancer has come back? What should I watch for?
● What will my options be if the cancer comes back?
Along with these sample questions, be sure to write down some of your own. Keep in
mind that doctors aren’t the only ones who can give you information. Other health care
professionals, such as nurses and social workers, can answer some of your questions.
