胰腺癌-Cancer of the Pancreas
来源:医学全在线 更新:2008/9/1 字体:

 

What are the treatment options cancer of the pancreas?

Treatment options that may be considered include surgery, chemotherapy and radiotherapy. The treatment advised for each case depends on various factors such as the stage of the cancer (how large the cancer is and whether it has spread), and your general health.

You should have a full discussion with a specialist who knows your case. He or she will be able to give the pros and cons, likely success rate, possible side-effects, and other details about the various possible treatment options for your type of cancer.

You should also discuss with your specialist the aims of treatment. For example:

Surgery
If the cancer is at an early stage, then there is a modest chance that surgery can be curative. (An early stage means a small tumour which is confined to within the pancreas and has not spread to the lymph nodes or other areas of the body).

The reason why the chance of cure is only modest is because in a number of cases thought to be in an early stage, some cells have already spread to other parts of the body but are not yet detectable by scans or other staging tests. In time they grow into secondary tumours.

If the cancer is at a later stage then surgery is not an option to cure the disease. Some surgical techniques may still have a place to ease symptoms. For example, it may be possible to ease jaundice caused by a blocked bile duct. A 'bypass' procedure may be used, or a stent may be inserted into the bile duct. (A stent is a small rigid tube made of plastic or metal which aims to keep a duct or channel open. It is usually inserted by instruments attached to an endoscope.)

Chemotherapy and Radiotherapy
Chemotherapy is a treatment which uses anti-cancer drugs to kill cancer cells, or to stop them from multiplying. Radiotherapy is a treatment which uses high energy beams of radiation which are focussed on cancerous tissue. This kills cancer cells, or stops cancer cells from multiplying. (There are separate leaflets which give more details about chemotherapy and radiotherapy.)

Chemotherapy or radiotherapy may be used alone, or may be used in addition to surgery.

What is the prognosis (outlook)?

If a cancer of the pancreas is diagnosed and treated at an early stage then there is a modest chance of a cure with surgery. As a rule, the smaller the tumour, and the earlier the tumour is diagnosed, the better the outlook. Some tumours which develop in the head of the pancreas are diagnosed very early as they block the bile duct and cause jaundice fairly early on. This obvious symptom is then investigated and surgery to remove a small tumour may be curative.

However, most cancers of the pancreas are advanced before they cause symptoms and are diagnosed. A cure is unlikely in most cases. However, treatment may slow down the progression of the cancer.

The treatment of cancer is a developing area of medicine. New treatments continue to be developed and the information on outlook above is very general. The specialist who knows your case can give more accurate information about your particular outlook, and how well your type and stage of cancer is likely to respond to treatment.
