Pleural Mesothelioma Stages - People often confuse the terms “prognosis” and “diagnosis.”
A prognosis is the likely outcome of a disease — like a forecast of how the
disease will affect a person. A diagnosis is the medical classification of
which disease a person has. A pleural mesothelioma prognosis is usually not
favorable, but it varies depending on the stage of the cancer and many other
factors.
Some of these factors, such as the cancer’s stage, cell
type, your age and gender, are beyond your control. However, you do have some
control in modifying other factors to positively influence your prognosis. Many
patients have lived well past their initial life expectancies by electing
treatment, improving their overall health and following the advice of knowledgeable
specialists.

Medical professionals regularly use these three related
terms to discuss prognosis. Although they are similar, they are not
interchangeable.
Prognosis
A prognosis is a prediction made by a qualified physician of
the likely result of your cancer. Doctors base your cancer prognosis on
statistics gathered from others with your type of cancer and stage of disease.
However, it is only an assessment. Many people have outlived their initial
prognoses, and you might be able to improve yours, too, by discussing it with
your doctor or our Patient Advocates.
Asbestos Mesothelioma Life Expectancy
Life expectancy is the estimated amount of time someone will
live after a diagnosis. A median life expectancy means half of patients are
expected to live longer and half are expected to live shorter.

What stages are
The stage of a cancer tells the doctor where it is, how big
it is and whether it has spread. The tests and scans you have when diagnosing
your cancer give some information about the stage. Knowing the stage helps your
doctor decide about the treatment you need.
Most people who are diagnosed with mesothelioma have an
advanced stage of cancer.
The staging used for mesothelioma in the chest (pleural
mesothelioma) is different to the staging for mesothelioma in the abdomen
(peritoneal mesothelioma).
Staging describes or classifies a cancer based on how much
cancer there is in the body and where it is when first diagnosed. This is often
called the extent of cancer. Information from tests is used to find out the
size of the tumour, which parts of the organ have cancer, whether the cancer
has spread from where it first started and where the cancer has spread. Your
healthcare team uses the stage to plan treatment and estimate the outcome (your
prognosis).
Pleural mesothelioma starts in the lining (membrane) that
protects and cushions the lungs (called the pleura). The most common staging
system for pleural mesothelioma is the TNM system. For this type of cancer,
there are 4 stages. Often the stages 1 to 4 are written as the Roman numerals
I, II, III and IV. Generally, the higher the stage number, the more the cancer
has spread. Talk to your doctor if you have questions about staging.
Only pleural mesothelioma is staged using the TNM system.
There is no staging system for mesothelioma of the lining of the abdomen
(peritoneal mesothelioma) or for rare types of mesothelioma. Find out more about staging cancer.
Stage 1A Mesothelioma
Cancer is in the lining of the chest wall (parietal pleura)
or the lining covering the lung (visceral pleura) on the same side of the chest
as the tumour.
Stage 1B Mesothelioma
Cancer is in the parietal or visceral pleura on the same
side of the chest as the tumour. It has also spread to at least one of the
following:
- the diaphragm
- the tissues of the lung
Cancer is in the parietal or visceral pleura on the same
side of the chest as the tumour. It has grown into at least one of the
following:
- the connective tissue (fascia) that makes up part of the chest wall
- the fat in the space between the lungs
- the soft tissues of the chest wall (but only one area)
- the lining of the heart (the pericardium) but not all of the way through it
Stage 2 Mesothelioma
Cancer is in the lining of the chest wall or the lining
covering the lung on the same side of the chest as the tumour. It may have also
grown into at least one of the following:
the diaphragm
the tissues of the lung
Cancer has spread to the lymph nodes within the chest on the
same side of the body as the tumour.
Stage 3A Mesothelioma
Cancer is in the parietal or visceral pleura on the same
side of the chest as the tumour. It has grown into at least one of the
following:
- the connective tissue that makes up part of the chest wall
- the fat in the space between the lungs
- the soft tissues of the chest wall (but only one area)
- the lining of the heart but not all of the way through it
- Cancer has also spread to the lymph nodes within the chest on the same side of the body as the tumour.
Stage 3B Mesothelioma
Cancer is in the lining of the chest wall or the lining
covering the lung on the same side of the chest as the tumour. It may have also
grown into at least one of the following:
- the diaphragm
- the tissues of the lung
- the connective tissue that makes up part of the chest wall
- the fat in the space between the lungs
- the soft tissues of the chest wall (but only one area)
- the lining of the heart but not all of the way through it
- Cancer has spread to the lymph nodes on the other side of the chest from the tumour.
Cancer is found in the parietal or visceral pleura on the
same side of the chest as the tumour. It has also grown into at least one of
the following:
- the chest wall and may have grown into the ribs
- the peritoneum
- the parietal or visceral pleura on the other side of the chest
- the esophagus, windpipe (trachea), heart or large blood vessels in the space between the lungs (mediastinum)
- the bones of the spine (vertebrae)
- the spinal cord
- through the lining of the heart
Stage 4 Mesothelioma
The cancer has spread to other parts of the body (called
distant metastasis), such as to the lung on the other side of the body, liver
or bones. This is also called metastatic pleural mesothelioma. Mesothelioma Life Expectancy Stage 4 is about 12 months. In most cases, the cancer will continue to spread, resulting in respiratory or heart failure.
Recurrent mesothelioma
Recurrent mesothelioma means that the cancer has come back
after it has been treated. It can come back in the part of the body where
mesothelioma starts, including the pleura, peritoneum, pericardium or the
lining that covers the testicles (tunica vaginalis). If it comes back in the
same place, it’s called local recurrence. If it comes back in tissues or lymph
nodes close to where it first started, it’s called regional recurrence. It can
also recur in another part of the body. This is called distant metastasis or
distant recurrence.
Mesothelioma Survival Rate
Survival rate refers to the percentage of people who survive
for a certain period of time after a diagnosis. These rates are usually
measured in 1- and 5-year increments. For example, the 1-year survival rate for
pleural mesothelioma is approximately 38 percent, meaning more than one-third
of patients live one year or longer after their diagnosis. Pleural Mesothelioma Stages.
