What Are Mesothelioma Survival Rates?

When discussing mesothelioma survival rates, you may hear other related terms such as life expectancy, which is the average time a person is expected to live based on birth year, current age, gender and other factors.

Mesothelioma affects life expectancy because the cancer reduces the number of years a patient is expected to live.

A 2015 meta study published in Translational Oncology analyzed 20 years of data, collected from 1992 to 2012. The five-year survival rate for peritoneal mesothelioma patients was more than five times higher than the rate for pleural patients.

Pleural and Peritoneal Mesothelioma Survival Rates
Year(s) Pleural Peritoneal
1 year 73% 92%
3 years 23% 74%
5 years 12% 52%
10 years 4.7% 39%

5-Year Relative Survival Rates for Mesothelioma

Relative survival rates are a way of comparing the survival of people with a specific disease over a period of time to those who don’t have the disease. The time period is typically five years after diagnosis.

The rate is calculated by dividing the percentage of patients still alive at the end of the time period by the percentage of people in the general population who are still alive. The resulting rate reveals if the disease shortens life span.

The National Cancer Institute’s Surveillance, Epidemiology, and End Results program, also known as SEER, groups cancer survival rates into localized, regional and distant stages. This essentially distills the four pleural mesothelioma stages into three, with localized representing stage 1, regional roughly representing stages 2 and 3, and distant representing stage 4.

5-Year Relative Survival Rates & Incidence for
Malignant Pleural Mesothelioma Patients
SEER Stage 5-Year Relative Survival Rate % of New Cases Diagnosed at Each SEER Stage
Localized 18% 10.5%
Regional 12% 17.5%
Distant 7% 61.1%
All SEER stages combined 10% 10.9% (unstaged cases)

Factors Affecting Mesothelioma Survival Rates

There are several things that affect how long a person will live after a mesothelioma diagnosis.

Individual Characteristics and Mesothelioma Survival

  • Tumor Location
  • Stage of disease
  • Mesothelioma cell type
  • Age at diagnosis and overall health
  • Gender
  • Race/Ethnicity

A 2018 analysis of 888 cases in the National Mesothelioma Virtual Bank cohort identified median overall survival of 15 months, on average, for pleural and peritoneal patients combined.

The most important factors associated with better survival were age (less then 45), female gender, epithelioid cell type, stage 1 disease, peritoneal occurrence and treatment combining surgery with chemotherapy.

Mesothelioma Tumor Location

There are four types of mesothelioma, and the site where the cancer originates affects patient outcomes. Survival is significantly better for peritoneal patients.

Quick Fact:
Half of peritoneal patients who undergo HIPEC live longer than five years.

An advanced peritoneal mesothelioma therapy called hyperthermic intraperitoneal chemotherapy (HIPEC) has significantly improved survival rates for this cancer.

The procedure combines cytoreductive surgery and heated chemotherapy. Not everyone qualifies for this aggressive procedure, but more than half who do live at least five years.

This compares to a median survival of less than 12 months for patients with pleural tumors. In select studies, heated chemotherapy has boosted peritoneal survival to between 40 and 92 months.

A 2020 study conducted at Brigham and Women’s Hosptial tested the equivalent surgery and heated chemotherapy on pleural mesothelioma patients. It reported acute kidney injury in 48.3% of patients, and none of these patients experienced a survival benefit from the procedure. What works for one type of mesothelioma may not work for another type.

The remaining two types of this asbestos-related cancer are pericardial and testicular. Together, these account for less than 2% of all cases. Median survival for testicular mesothelioma, the rarest type, is 24 months.

Pericardial mesothelioma is very rare, with only 200 documented cases in the medical literature. It develops on the lining of the heart and has a median survival ranging from six weeks to 15 months.

Beating the Odds: Alyssa Hankus

Alyssa Hankus is one of the youngest long-term mesothelioma survivors in the U.S. She was diagnosed with advanced peritoneal mesothelioma at age 15. Thanks to surgery and the HIPEC procedure, Hankus has been in remission since 2002. She now lives every day to the fullest and looks forward to what the next chapter of her life has in store.

Stage of Disease

The stage of mesothelioma at diagnosis is a strong predictor of overall survival. People with stage 1 or stage 2 mesothelioma, before cancer has spread, have the best survival rates.

Early-stage patients who receive prompt treatment experience improved survival. They are more likely to qualify for surgery and other aggressive treatments. More aggressive therapies are associated with better outcomes.

Most cases of pleural mesothelioma are not diagnosed until stage 3 or stage 4.

At these stages, the tumor is large or has spread beyond the original cancer location. Being diagnosed at later stages mean the disease is more difficult to treat and is associated with poorer survival rates.

There is no established cancer staging system for peritoneal mesothelioma. Some researchers have developed their own systems based on the TNM staging system. In TNM, T = tumor size, N = lymph node involvement and M = metastasis (cancer spread) to describe the extent of cancer.

One example is the peritoneal cancer index (PCI), which places this tumor type into three stages instead of the usual four for other cancers. A 2011 international study involving 294 patients treated with cytoreductive surgery and HIPEC, used PCI to describe patient survival.

Peritoneal Mesothelioma Survival by Peritoneal Cancer Index (PCI) Staging
PCI Stage Year 1 Year 5
Stage 1 95% 87%
Stage 2 87% 53%
Stage 3 66% 29%

Pleural mesothelioma does not have favorable survival rates when compared with the survival rates of peritoneal disease. The pleural disease can be harder to treat.

Patients often are not diagnosed early enough to receive the most aggressive available cancer therapies and may not be healthy enough to withstand invasive surgeries in particular.

Beating the Odds: Russell Lamkins

Russell Lamkins was diagnosed with stage 3 inoperable pleural mesothelioma in August 2014. Doctors told him he had a year to live. But Lamkins beat his grim prognosis thanks to Moffitt Cancer Center’s transarterial chemoperfusion study, led by thoracic surgeon Dr. Jacques Fontaine. The novel treatment involves delivering high-doses of chemotherapy directly to specific blood vessels that feed tumors.

Mesothelioma Cell Type (Tumor Histology)

The mesothelioma cell type, or tumor histology, impacts patient survival. The cancer has three primary cell types: Epithelioid, sarcomatoid and biphasic.

The most common cell type is epithelioid, which is also the least aggressive. It responds best to treatment. Median survival for patients with this cell type is 12 to 24 months.

Sarcomatoid mesothelioma is the most aggressive cell type. Patients with this diagnosis have a median survival of six to eight months.

Biphasic tumors have epithelioid and sarcomatoid features. More epithelial cells mean a better prognosis for mesothelioma patients. If the tumor is mostly sarcomatoid cells, life expectancy is decreased. Patients with a biphasic cell diagnosis have a median survival of around 13 months.

Age at Diagnosis and Overall Health

Older mesothelioma patients have lower survival rates, on average, compared with younger patients. More than 55% of patients diagnosed before the age of 50 live one year. Less than 30% of patients 75 or older live the same amount of time.

One-Year Mesothelioma Survival by Age
Age Range 1-Year Survival Rate
< 50 57.2%
50 – 64 51.2%
65 – 74 40.9%
75+ 28.5%

Patients diagnosed before age 50 have an estimated 25% chance of surviving a decade. That drops to 5.4% for patients between the ages of 50 and 64.

The five-year survival rate for mesothelioma patients diagnosed between ages 65-74 is 6.7%. That rate falls to 3.8% for people 75 and older at diagnosis.

Younger patients tend to be healthier than older patients, which means they are eligible for more aggressive and effective therapies.

Younger patients also are less likely to suffer from other chronic conditions such as pulmonary disease, diabetes or a history of other cancers. Better general health allows for enrollment in clinical trials, too.

Mesothelioma survival rate by age and gender table


Most asbestos exposures occur in the workplace. Industrial jobs traditionally held by men present the highest risk. This helps explain why men account for the majority of all cases.

However, even though men make up most cases of the disease, women with mesothelioma appear to survive longer than men regardless of age, cancer stage, race or type of treatment.

For every age group studied in the SEER program, women fared significantly better than men.

Mesothelioma Survival Rates by Gender
Gender 1 Year 2 Years 3 Years 4 Years 5 Years
Males 37.6% 17.4% 10.4% 7.7% 5.9%
Females 45.4% 29.3% 22.2% 18.6% 16.0%

There are several possible reasons why women fare better than men. Some researchers believe the improved survival could be explained by hormonal differences between sexes.

Women are more likely to be diagnosed with peritoneal mesothelioma, too. This tumor type has better survival compared with pleural tumors, which are more common among men. This skews the survival rates to favor women living longer, on average.

Beating the Odds: Sallie Morton

Sallie Morton was 87 when she received her pleural mesothelioma diagnosis in July 2013. She felt she was too old to go through treatment, but that didn’t stop her from living far past her life expectancy. Morton is among the 8.3% of women in her age range who survived more than four years after a diagnosis.

Mesothelioma is almost exclusive to white individuals, who make up 95% of patients.

Part of this difference is because black and Hispanic individuals are less likely to be diagnosed with any type of cancer, including mesothelioma.

Also, non-white individuals historically may have been less likely to hold industrial jobs associated with heavy asbestos exposure. Data from SEER shows blacks and Hispanics account for only 8% of all cancer diagnoses.

Mesothelioma Survival Rates by Race
Race 1 Year 2 Years 3 Years 4 Years 5 Years
White* 39.7% 20.2% 12.9% 9.8% 7.8%
Black and Hispanic 35.2% 21.4% 16% 14.3% 12%
Beating the Odds: Kasie Coleman

Peritoneal mesothelioma survivor Kasie Coleman was 34 when she received her diagnosis. After two cytoreductive surgeries and a pair of HIPEC procedures, Coleman has been in remission since June 2012. When she’s not running her Sugarbelle Bakery business in Baton Rouge, Louisiana, she enjoys traveling with her husband and checking items off her bucket list.

A 2015 study of 13,734 pleural mesothelioma cases in the SEER database found black patients lived longer than white patients despite being less likely to undergo aggressive surgery.

Typically, patients who have surgery survive longer than those who do not.

How Do Mesothelioma Survival Rates Apply to Me?

Thanks to advances in mesothelioma treatments, many patients are beating the odds and living beyond average survival rates.

Cancer survival rates also do not take into account recent advances in treatment, such as immunotherapy and other targeted therapies available through clinical trials.

Survival rates only considers people diagnosed in the past. Anyone diagnosed today may have more available treatment options and a better prognosis going forward.

Beating the Odds: Chris Gibney

Chris Gibney credits his medical team and strong support from his family and friends for his long-term survival. Shortly after his pleural mesothelioma diagnosis in 2005, Gibney underwent an aggressive pleurectomy and decortication surgery. He continues celebrating more than a decade of remission.

Ways to Improve Mesothelioma Survival Rates

Many long-term mesothelioma survivors attribute their success living with the disease to a multidisciplinary approach to treatment. Many in this group include the following factors as helping them do well after diagnosis.

  • Seeking care and treatment from mesothelioma specialists
  • Trying clinical trials
  • Seeking referrals for exercise and rehabilitation to rebuild strength
  • Making nutritional changes to improve health and well-being
  • Trying complementary and alternative therapies in conjunction with, but not in place of, conventional cancer treatment

Common Questions About Mesothelioma Survival Rates

Is mesothelioma always fatal?

Malignant mesothelioma is considered an aggressive and fatal disease. Most mesothelioma patients only survive approximately 12 months after diagnosis. There is no cure for this cancer, but with treatment, patients have extended their life expectancies well beyond their initial prognosis.

What is the difference between a mesothelioma survival rate and mortality rate?

Survival rates refer to the percentage of cancer patients who live a certain number of years after their diagnosis. For example, 23% of pleural mesothelioma patients live for three years or more. The mesothelioma mortality rate is the number of deaths within specific geographical locations and groups of people. For example, in 2015, there were 2,597 mesothelioma deaths in the United States.

How does the survival rate of mesothelioma compare to lung cancer?

The five-year survival rate for mesothelioma patients is approximately 12%. Comparatively, about 18% of asbestos-related lung cancer patients survive more than five years after diagnosis.
