Treatment

Your treatment will depend on what type of small bowel cancer you have. This page is about the treatment you might have if you have small bowel adenocarcinoma.

Treatment for other types of small bowel cancer, such as neuroendocrine tumours and lymphoma will be different.

Deciding which treatment you need

A team of doctors and other professionals discuss the best treatment and care for you. They are called a multidisciplinary team (MDT).

The treatment you have depends on:

  • where your cancer is
  • how far it has grown or spread (the stage)
  • the type of cancer
  • how abnormal the cells look under a microscope (the grade)
  • your general health and level of fitness

Your doctor will talk to you about your treatment, its benefits and the possible side effects.

Treatments can include:

  • surgery
  • radiotherapy
  • chemotherapy

If your cancer hasn't spread to other parts of the body

You will probably have surgery if your cancer hasn’t spread and you are fit enough. Your surgeon removes the cancer along with a clear border of tissue around it. They also remove the nearest lymph nodes.

Having chemotherapy after surgery (adjuvant treatment) might help to reduce the risk of your cancer coming back, especially if your cancer began in the duodenum. But more evidence is needed into the benefits of adjuvant chemotherapy.

If your cancer has spread nearby, you might not be suitable for surgery.  But your doctor might recommend chemotherapy at first and then depending on how you respond you might have surgery afterwards.

If your cancer has spread to other parts of the body

Treatment options include:

  • surgery to relieve a blocked bowel
  • unblocking the bowel with a tube called a stent
  • chemotherapy
  • radiotherapy

Treatment

Surgery to remove the cancer

The type of surgery you have to remove the cancer depends on where the cancer is in the small bowel.

You are most likely to have a type of surgery called wide excision.

In a wide excision, your surgeon will remove the:

  • cancer
  • surrounding tissues
  • lymph nodes

But for cancer in the top of the duodenum you might have a pancreaticoduodenectomy. The surgeon removes:

  • part of your pancreas
  • your gallbladder

The surgeon also might remove part of your stomach. 

Taking out the head of the pancreas

For cancer on the side of your (distal) ileum the surgeon might also remove part of your large bowel.

Surgery for bowel obstruction

Sometimes cancer can grow so that it completely blocks the bowel. This is called a bowel obstruction. The waste from the food you have digested can't get past the blockage. 

To relieve symptoms, it is sometimes possible to:

  • unblock the bowel by putting in a tube called a stent
  • remove the blocked section of bowel

After removing the part of bowel with the cancer, your surgeon will join the two ends of the remaining bowel together. You might need an ileostomy if this is not possible. This is when part of the small bowel is brought up onto the surface of the abdomen to form a stoma.

You wear a special bag over the stoma to collect your bowel movements (faeces).

Chemotherapy 

Chemotherapy uses anti cancer (cytotoxic) drugs to destroy cancer cells. The drugs circulate throughout the body in the bloodstream.

You might have chemotherapy to reduce or control symptoms of advanced cancer. 

You might have:  

  • fluorouracil (5FU)
  • folonic acid, fluorouracil and oxaliplatin (Folfox)
  • oxaliplatin and capecitabine (Capox)
  • folonic acid, fluorouracil and irinotecan (Folfiri)

Radiotherapy 

Radiotherapy uses high energy rays to destroy cancer cells.

Radiotherapy isn’t used much for small bowel cancer. It is mainly used to treat more advanced small bowel cancers. Advanced cancer means that the cancer has spread to another part of the body.

Small bowel cancer may be advanced either when it is diagnosed or if it comes back after treatment. Radiotherapy can help to control symptoms you have because of advanced cancer, such as pain. 

Research into treatment

Finding out how well treatments work when a cancer is rare is difficult. It is harder to organise trials because there are fewer people that can take part. This means it takes longer to get meaningful results.

Researchers are interested in:

  • whether chemotherapy after surgery can improve survival
  • comparing different cancer drugs

Coping

Coping with a diagnosis of a more aggressive cancer can be especially difficult, both practically and emotionally. Being well informed about your cancer and its treatment can make it easier to make decisions and cope with what happens.

Talking to other people who have the same thing can also help.

Our discussion forum Cancer Chat is a place for anyone affected by cancer. You can share experiences, stories and information with other people who know what you are going through.

The Rare Cancer Alliance offer support and information to people affected by rare cancers.
