Colorectal Cancer
Colorectal cancer (CRC), also known as bowel cancer, is a potentially fatal tumour that starts on the inside wall of the bowel. It is quite common, with almost 3000 New Zealanders diagnosed with it each year. Colorectal cancer can develop in any part of the large bowel, including the colon and rectum. Symptoms include:
- Discomfort in the abdomen
- Blood in the stools
- Sudden weight loss
- Weakness or fatigue associated with anaemia (a deficiency in red blood cells)
Note: You should check with your doctor regarding these symptoms so that you get professional advice as these symptoms may not necessarily indicate bowel cancer.
Diagnosis of Colorectal Cancer
There are two main tests for colorectal cancer, and a doctor may choose one or both of them in diagnosis. These are:
- Faecal occult blood test – used to detect blood in the stool, which may indicate colorectal cancer
- Colonoscopy performed by colorectal surgeons or gastroenterologists. A colonoscopy is a procedure where a doctor uses a colonoscope (a long, flexible instrument about 1/2 inch in diameter) to view the lining of the colon.
Treatment for Colorectal Cancer
Most people with CRC will undergo surgery at some point to try and remove the tumour. Dependent on the stage (describes how much the cancer has spread, a low stage is local, Stage 1; a high stage is wide spread, stage 4) and aggressiveness (speed of growth and pathology or how it looks under a microscope) of the cancer, chemotherapy and other medications known as biological therapy can also be given.
Chemotherapy
Xeloda (capecitabine) is fully funded for colon cancer and is the most commonly used chemotherapy in the treatment of early and advanced colon cancer in NZ. Xeloda tablets can be taken at home allowing patients more independence to live their lives, as they spend less time and money travelling to cancer centres to receive treatment. Read more about Xeloda on the site for consumer medicines information (CMI). For more information about Xeloda click on the product logo.
Biologic therapies
Biologic therapies can be given alongside chemotherapy to improve survival times for patients with cancer. Avastin is a biologic therapy (also known as a targeted agent), which has been proven to increase survival times for people with advanced or metastatic colorectal cancer.
Avastin (bevacizumab) is not funded, and patients must pay for this treatment themselves. Your Oncologist or colorectal surgeon will be able to tell you what it may cost you to be treated with Avastin. Read more about Avastin on the site for consumer medicines information.
