Common types of upper gastrointestinal cancers include:
- Pancreas, and
These tumours are often found in the lining of tissue in each of these areas. Symptoms are usually not easily demonstrated until the tumour has grown enough in size.
There are various symptoms of an upper gastrointestinal cancer and will vary depending on the location in the tumour. Common symptoms include:
- Difficulty or pain on swallowing
- Constant reflux
- Pain in the chest, upper abdomen or in the back
- Nausea and vomiting
- Rapid weight loss
This group of cancers do have several associated risk factors and those who are concerned should seek consultation with their doctor. Risk factors for upper gastrointestinal cancer include:
- Family history
- Excessive drinking
- Chronic gastro-oesophageal reflux
- History of head neck cancer, coeliac disease or Plummer-Vinson syndrome
Surgery is the most common treatment for most upper gastrointestinal cancers. However, radiation therapy may be recommended in addition to surgery or when a patient is not a suitable candidate to undergo surgery.
External Beam Radiation Therapy for Gastrointestinal Cancer
External beam radiation therapy is the routine approach for these cancer types. The use of intensity modulated radiation therapy, volumetric modulated arc therapy and Brainlab allow for optimal dose coverage of tumour target while minimising dose to nearby organs, such as the heart, spinal cord, bowel, liver and lungs.
The use of these advanced treatment techniques allows for improved management of side effects and increased dose prescriptions to be delivered safely to achieve positive patient outcomes.
Brachytherapy for Gastrointestinal Cancer
High-Dose rate brachytherapy is able to be executed by the implantation of transfer catheters in and around the tumour site. This allows the radioactive source to travel and stop in planned positions to achieve the required radiation dose. The benefit of this treatment approach is the extremely localised delivery of the radiation and the minimal exposure to surrounding healthy tissue.
