Malignant Mesothelioma: Your Chances for Recovery (Prognosis)
What is a prognosis?
Prognosis is the word your healthcare team may use to describe your likely outcome from cancer and cancer treatment. A prognosis is a calculated guess. It’s a question many people have when they learn they have cancer.
Making a choice
The decision to ask about your prognosis is a personal one. It’s up to you to decide how much you want to know. Some people find it easier to cope and plan ahead when they know their prognosis and the statistics for how well a treatment might work. Other people find statistics confusing and frightening. Or they might think statistics are too general to be useful.
A healthcare provider who is most familiar with your health is in the best position to discuss your prognosis with you and explain what the statistics may mean in your case. At the same time, you should keep in mind that your prognosis can change. Cancer and cancer treatment outcomes are hard to predict. For instance, a favorable prognosis (which means you’re likely going to do well) can change if the cancer spreads to key organs or doesn’t respond to treatment. An unfavorable prognosis can change, too. This can happen if treatment shrinks and controls the cancer so it doesn’t grow or spread.
What goes into a prognosis
When figuring out your prognosis, your healthcare provider will consider all the things that could affect the cancer and its treatment. He or she will look at risk estimates about the type and stage (extent) of the cancer you have. These estimates are based on what results researchers have seen over many years in other people with the same type and stage of cancer.
If your cancer is likely to respond well to treatment, your healthcare provider will say you have a favorable prognosis. This means you’re expected to live many years and may even be cured. If your cancer is likely to be hard to control, your prognosis may be less favorable. The cancer may shorten your life. It’s important to keep in mind that a prognosis states what’s likely or probable. It is not a prediction of what will definitely happen. No healthcare provider can be fully certain about an outcome.
Your prognosis depends mainly on:
The type and location of the cancer
The stage (extent) of the cancer
Your overall health
Your treatment decisions
How well your cancer responds to treatment
Understanding survival rates
Survival rates show what portion of people live for a certain length of time after being told they have cancer. The rates are often grouped for people with certain types of cancer. Many times, the numbers used refer to the 5-year survival rate. That’s how many people are living 5 years after diagnosis. The survival rate includes:
People who are cancer-free
People who still have signs of cancer. (These people may or may not be getting treatment for their cancer.)
What are the survival rates for malignant mesothelioma?
In general, the prognosis for people with mesothelioma tends to be better if the cancer is caught early enough where surgery is an option for treatment.
Here are the 5-year survival rates for mesothelioma, according to the National Cancer Institute.
Overall, the 5-year survival rate for mesothelioma is about 9 percent.
People who are younger at the time of diagnosis tend to do better than those who are older. For instance, if mesothelioma is diagnosed before the age of 65, the 5-year survival rate is about 18 percent. In people 65 or older, the 5-year survival rate is about 6 percent.
These numbers are adjusted to account for the fact that some people with mesothelioma may die from other causes.
Talk with your healthcare provider
You can ask your healthcare provider about survival rates and what you might expect. But remember that statistics are based on large groups of people. They cannot be used to say what will happen to you. No two people are exactly alike. Treatment and how well people respond to treatment vary.
