Pancreatic cancer


Diagnosing pancreatic cancer

If your doctor thinks you may have pancreatic cancer, you will need some tests to confirm the diagnosis. Sometimes you may also have tests to check for gene changes in the cancer.

The tests you have will depend on the symptoms, type and stage of the cancer. You will not have all the tests described below.

Your guide to best cancer care

A lot can happen in a hurry when you’re diagnosed with cancer. The guide to best cancer care for pancreatic cancer can help you make sense of what should happen.

It will help you with what questions to ask your health professionals to make sure you receive the best care at every step.

Blood tests

You are likely to have blood tests to check your general health and see how well your liver and kidneys are working. Some blood tests look for proteins produced by cancer cells. These proteins are known as tumour markers.

Tumour markers

Many people with pancreatic cancer have higher levels of the tumour markers CA 19-9 (carbohydrate antigen) and CEA (carcinoembryonic antigen) in their bloodstream. On their own, however, these tumour markers can’t be used to diagnose.

This is because some people with pancreatic cancer have normal levels of these markers, and other conditions can also raise the levels of these markers in the bloodstream. It is normal for the levels of these tumour markers to go up and down.

Your doctor will look for sharp increases and overall patterns. Raised levels can tell your doctor more about the cancer and, after diagnosis, can also show how well the treatment is working.

Imaging scans

Imaging scans are tests that create pictures of the inside of the body. Different scans can provide different details about the cancer.

Types of imaging tests

 

Molecular and genetic testing

Some people are born with a gene change that increases their risk of cancer (an inherited faulty gene), but most gene changes that cause cancer build up during a person’s lifetime (acquired gene changes).

In some circumstances, your doctors may recommend extra tests to look for acquired gene changes (molecular tests) or inherited gene changes (genetic tests).

Tissue sampling

If imaging scans show there is a tumour in the pancreas, your doctor may remove a sample of cells or tissue from the tumour (biopsy).

This is the main way to confirm if the tumour is cancer and to work out exactly what type of cancer it is. A specialist doctor called a pathologist will examine the sample under a microscope to check for signs of cancer.

Sometimes, the results are not clear and a second biopsy is needed.

A biopsy can be taken in different ways, including:

  • with a needle – a sample of cells may be collected with a fine needle (fine needle biopsy), or a tissue sample may be collected with a larger needle (core biopsy). A fine needle or core biopsy can be done during an endoscopic procedure. Another method is to insert the needle through the skin of the abdomen, using an ultrasound or CT scan for guidance.
  • during keyhole surgery – also called a laparoscopy or minimally invasive surgery, a laparoscopy is sometimes used to look inside the abdomen to see if the cancer has spread to other parts of the body. It can also be done to take tissue samples before any further surgery. 
  • during surgery to remove the tumour – if you are having a larger operation to remove the tumour, your surgeon may take the tissue sample at that time.

“I asked the surgeon what caused it, and he said, ‘We don’t know, Phil.’ He got me to focus on what had to be done and to just get on with it. It’s easy to say now that you need to get on the front foot and work with your treatment team, but the diagnosis is a terrific blow.” Phil

Staging pancreatic cancer

The test results will show what type of pancreatic cancer it is, where in the pancreas it is, and whether it has spread. This is called staging, and it helps your doctors work out the best treatment options for your situation.

Prognosis

Prognosis means the expected outcome of a disease. You may wish to discuss your prognosis with your doctor, but it is not possible for anyone to predict the exact course of the disease.

To work out your prognosis, your doctor will consider:

  • test results
  • the type, stage and location of the cancer
  • how the cancer responds to initial treatment
  • your medical history
  • your age and general health.

As symptoms can be vague or go unnoticed, most pancreatic cancers are not found until they are advanced, which usually means treatment cannot remove all the cancer.

If the cancer is diagnosed at an early stage and can be surgically removed, the prognosis may be better.

It is important to know that although the statistics for pancreatic cancer can be frightening, they are an average and may not apply to your situation.
