What is meant by prognosis?

A prognosis is a doctor’s opinion about how well someone will recover from an illness. The prognosis and survival rates of people with neuroendocrine tumours (NETs, which you may also hear referred to as carcinoid tumours, GI-NETs, GEP-NETS, pancreatic NETs and lung NETs) depend on several factors listed here.

  • Site – where the primary tumour started in your body
  • Metastasis – whether it has spread to other organs
  • Size – how large it is
  • Symptoms – how it affects you physically and emotionally
  • Functional or non-functional – whether it produces excess hormones
  • Stage – how advanced the cancer is
  • Grade – how fast or slow it is growing
  • Complications – what other medical conditions it may have caused

Other factors that will affect what will happen in the long term are your health in general and whether or not you have any other medical conditions.

Ronny, Patient – Living with NETs

“There is no such thing as ‘good’ cancer. Some cancers can be declared in remission after a period but some cancers can stay with you for the rest of your life.”

What is meant by staging and grading of NETs?

To help determine what treatment may be best for a particular situation, doctors often stage and grade tumours.

Cancer staging – gives a measure of how large a tumour is and how far it has spread from the original location (primary site) in the body. Cancer stages range from 1 to 4, with the higher the number the greater the size and spread.

Cancer grading – gives an indication of how quickly or aggressively tumours are growing. Grading involves looking at a sample of tissue under the microscope and provides a measure of how severe the cancer is and how quickly the tumours may develop.

How do doctors use staging and grading information?

NETs are usually classified according to their location in the body.

The information provided by staging and grading may give clues to the likely long-term outcome for a patient but it is important to note that having a high stage or grade alone does not necessarily mean that there is likely to be a worse outcome.

For example, someone with stage IV, grade 1 NETs may live many years with treatment as his or her cancer is relatively slow growing despite being large or spread throughout the body.
