A patient’s mesothelioma life expectancy may be improved by selecting a mesothelioma specialist and undergoing a variety of treatment options to extend and improve life.

How Can I Improve My Life Expectancy?

Life expectancy is the number of months or years a patient is expected to live with a disease or illness. Mesothelioma life expectancy often ranges from about 12-21 months. However, there are many factors that contribute to life expectancy and each patient is unique. Through treatment and healthy habits, some patients are able to outlive their prognosis significantly.

Factors Affecting Life Expectancy

  • Mesothelioma Stage Icon


    The stage of a patient’s disease is a designation of how advanced it is. Less advanced stages (1 and 2) have longer life expectancies.

  • Mesothelioma Location Icon


    The location of a patient’s tumor affects the type of treatment available. Certain treatment options are more effective than others.

  • Mesothelioma Cell Type Icon

    Cell type

    The patient’s life expectancy varies by cell type. Certain cell types spread more quickly than others.

When a patient is diagnosed with mesothelioma, the first question that tends to come to mind once the shock subsides is, “How long do I have left?” Patients want to know how much longer they can expect to live in a straightforward way without being overwhelmed by confusing statistics.

Nearly half of all patients are now living 12 months or longer.

Although there is no way to tell for sure how long an individual patient’s life expectancy will be, an estimate based on the experience of other patients can be provided.

Early Stage Pleural Mesothelioma

Early stage (stage 1 or 2) pleural mesothelioma patients have the best prognosis compared to patients diagnosed with late stage pleural mesothelioma. Patients diagnosed with stage 1 pleural mesothelioma have an average life expectancy of 38 months.

Those diagnosed with stage 2 pleural mesothelioma have a life expectancy of 19 months. These life expectancies include all the cell types of mesothelioma (epithelioid, sarcomatoid, and biphasic) and are based on patients whose average age was 60 years old.

The life expectancy for the different cell types of mesothelioma varies. Life expectancies for pleural mesothelioma patients with epithelioid cell types are higher than patients with sarcomatoid cell types.

This is because sarcomatoid type cells can spread faster than epithelioid type cells. Early stage patients are typically eligible for surgical treatment regardless of cell type, which, in most cases, can improve life expectancy.

Those who have been diagnosed with biphasic pleural mesothelioma do not have as clear a picture as those with other cell types. The biphasic cell type is a combination of epithelioid and sarcomatoid cells, and the life expectancy varies on the ratio of the two cell types.

If there is a heavier epithelioid influence, the life expectancy is longer than if there is a larger presence of sarcomatoid cells.

The average life expectancy for patients with biphasic pleural mesothelioma is about 21 months, but this average can be substantially higher for some patients.

Detection of pleural mesothelioma at stage 1 or 2 is rare. However, the earlier the mesothelioma is detected, the sooner the treatment can begin. Curative surgeries, like the extrapleural pneumonectomy (EPP) and the lung-sparing pleurectomy, are performed on patients with early stage pleural mesothelioma, and in some cases these surgeries are even used on late stage patients.

Late Stage Pleural Mesothelioma

Patients with late stage pleural mesothelioma have a poorer life expectancy than early stage pleural mesothelioma. Patients diagnosed with stage 3 pleural mesothelioma have a life expectancy of 11 months, while patients with stage 4 pleural mesothelioma are expected to live around seven months.

Patients in these stages who are over the age of 65 have an average survival of six months, but some patients at this age live much longer, especially if they are in otherwise good health.

Late stage patients with epithelioid pleural mesothelioma have a life expectancy of 10-12 months. These patients tend to respond best to treatment, such as chemotherapy and radiation. Patients with a sarcomatoid or biphasic cellular makeup do not respond to treatment as well as epithelioid patients, but treatment is still an option.

Please input the data for the chart.

After patients are diagnosed with late stage pleural mesothelioma, there are a number of things they can do to increase their prognosis. Patients can seek the help of a mesothelioma specialist who can determine the best treatment plan for their unique diagnosis.

Late stage pleural mesothelioma patients can also get involved in several clinical trials, which may present previously unavailable treatment options.

These trials can potentially open up treatment options, such as surgery or novel therapies, that weren’t previously available to the patient. Get involved in clinical trials available for your diagnosis.

Pleural Mesothelioma Life Expectancy by Stage

Pleural Mesothelioma Life Expectancy

Peritoneal Mesothelioma

There is no accepted staging system for peritoneal mesothelioma; however specialists do categorize it as localized or metastatic. Patients with localized tumors are considered an early stage diagnosis in cases of peritoneal mesothelioma.

The unusual origins pertaining to peritoneal mesothelioma and its development means methods for diagnosis, staging and management haven’t been definitely established. Less is understood about peritoneal mesothelioma because it is more rare (about 1/4 of all mesothelioma cases) than pleural mesothelioma. However, the average life expectancy for patients diagnosed with peritoneal mesothelioma is 12 months.

Factors such as age, gender and cell type tend to have the same effect on life expectancy in peritoneal patients as other types of mesothelioma. There are very few approximations of life expectancy for biphasic or sarcomatoid cell types because these diagnoses are extremely rare.

Despite the rarity of peritoneal diagnoses, there is some good news for these patients:

  • Peritoneal patients have some of the longest life expectancies
  • The cancerous growth doesn’t seem to spread as quickly as pleural mesothelioma
  • Surgical treatment depends more on overall health and less on the stage

Some studies suggest the life expectancies for the biphasic and sarcomatoid cell types are about six months. As may be expected, patients whose tumor is localized (and hasn’t spread) have longer life expectancies, while those whose peritoneal mesothelioma has spread have shorter life expectancies. Early diagnosis also plays a huge role in improved life expectancies.

A study conducted by Dr. Paul Sugarbaker, a leading peritoneal mesothelioma specialist, showed that life expectancies are significantly improved in patients who have cytoreductive surgery with intraoperative chemotherapy.

The average life expectancy for patients who had surgery is 50-60 months, equating to approximately half of patients living up to five years. This life expectancy is more common among patients with an epithelioid cell type.

Other studies report even higher survival times. One such study in 62 patients demonstrated an overall survival time of 79 months. It is assumed in the mesothelioma community that life expectancies are higher when cytoreductive surgeries are successful in removing as much of the cancerous tumor as possible.

Life Expectancy by Cell Type

Cell type is another important factor affecting life expectancy. Cell type is important because certain cells are able to spread more quickly than others. Preventing metastasis is the most important aspect of having a better life expectancy.

Epithelioid cell types show the best life expectancies in all mesothelioma patients regardless of their age, gender or mesothelioma type because these cells aren’t as capable of spreading as biphasic and sarcomatoid cell types.

  • Epithelioid Mesothelioma


    Longest Life Expectancy
    Epithelioid cells are the most prevalent and also the most treatable. They are also found in other malignancies including lung cancers, so there is plenty of information on what treatment is most effective

  • Biphasic Mesothelioma


    Medium Life Expectancy
    Biphasic cell variations are the most difficult because it is a combination of both epithelioid and sarcomatoid cells. The unpredictable nature of these cells can complicate treatment. Patients tend to live longer when epithelioid cells make up the majority of biphasic mesothelioma.

  • Sarcomatoid Mesothelioma


    Shorter Life Expectancy
    Sarcomatoid cells are often more difficult to treat because they form fluid pockets rather than a singular distinctive tumor. This allows these cells to rapidly spread to lymph nodes and other organs.

The success of treatment is largely determined by cellular makeup of the mesothelioma. There are unique treatment options available for each cell type. This is why it’s important to locate a mesothelioma specialist who specializes in your cell type.

Common Questions About Mesothelioma Life Expectancy

What is the usual life expectancy for mesothelioma?

The average life expectancy for mesothelioma is 1-2 years, more specifically 12-21 months. This length of time is improving due to advancements in treatment and medical care, in addition to a growing number of experienced specialists and more knowledge of this cancer.

How does life expectancy change by type of mesothelioma?

The life expectancy for peritoneal mesothelioma without treatment is 1-2 years, similar to pleural mesothelioma. However, there are more stories of long-term survival for people with peritoneal mesothelioma who receive aggressive surgery, which can lead to a life expectancy of 3-5 years.

How does the stage of mesothelioma affect life expectancy?

The earlier stages of mesothelioma (stage 1 and stage 2) have a much better life expectancy than the later stages. Stage 1 mesothelioma, for instance, has a life expectancy of 2-3 years. The other stages are:

  • 19 months for stage 2
  • 16 months for stage 3
  • 11 months for stage 4

What is the life expectancy for the three cell types of mesothelioma?

Epithelioid mesothelioma, the most common type of this cancer, has the best life expectancy of the three cell types. Epithelioid mesothelioma has a life expectancy of 27 months. For the other two cell types:
