What is the survival rate for mesothelioma?
For pleural mesothelioma, the type in the lining of the lungs, the 5-year relative survival rate is 15%. Relative survival compares people who have the cancer with similar people of the same age who do not. These figures cover people diagnosed from 2015 to 2021 in the national SEER cancer registry. Grouped by how far the cancer had spread, the rates are 23% localized, 15% regional, and 11% distant. Those groupings are not the same as stages 1 to 4. No rate can tell you what will happen to your loved one.
Can you survive mesothelioma?
Yes, people do survive mesothelioma, sometimes for many years, though it is usually not curable. The National Cancer Institute says standard treatment for all but localized mesothelioma is generally not curative. A specialist center may aim at long-term control for a few people whose disease is still limited to one area. Only a specialist can say whether that applies to your loved one. Immunotherapy uses drugs that help the immune system fight cancer. The American Cancer Society says chemotherapy and immunotherapy combinations have clearly improved outcomes for many people.
Does anyone survive mesothelioma?
Yes, long-term survivors are real, and they have been studied as a group. A 2025 report in the Annals of Thoracic Surgery pooled 276 people who lived five years or more after surgery. Of those, 104 were still alive when the analysis was done. About 9 in 10 had epithelioid mesothelioma, the slower-growing cell type. All were treated at high-volume centers, and everyone counted was well enough for major surgery. The study counted survivors only, so it shows that long survival happens without telling you the odds.
Who is the longest living mesothelioma survivor?
There is no official record of the longest living mesothelioma survivor, because no registry tracks individual survivors that way. You will find personal stories online of people alive 10 or 20 years after diagnosis. Some are genuine, but one story is not a statistic. What is documented is a 2025 study of 276 people who lived at least five years after surgery. They were treated at expert centers, and their median age was 59. Ask your loved one's team what is realistic for them.
What is the difference between a survival rate and life expectancy?
A survival rate is a percentage of people still alive at a set point in time. Life expectancy is usually reported as median survival, which is a length of time. The 15% figure above is a relative survival rate, not a count of 15 people out of every 100. A median of 18 months means half the people in that group lived longer than 18 months and half lived less. A median is a midpoint, not a deadline, and not a prediction for any one person.
What does a 5-year relative survival rate actually mean?
A 5-year relative survival rate compares people who have the cancer with similar people who do not. At 15%, people with pleural mesothelioma were about 15% as likely to be alive five years later. It is not a count of how many people lived that long. It also does not mean anyone lives only five years. These figures cover diagnoses from 2015 to 2021, so they cannot reflect treatments approved since then. The American Cancer Society says people diagnosed now might do better than these numbers show.
Why do mesothelioma survival numbers differ from site to site?
Survival numbers differ from site to site because different sources measure different things. Some quote 5-year relative survival from the SEER registry, which counts everyone diagnosed in a set window. Others quote median survival from one trial or one surgical center, where patients were chosen because they were fit enough for treatment. Neither is wrong, but they are not interchangeable. When you read a figure, look for what it measures, who was counted, and when they were diagnosed.
Are mesothelioma survival rates improving?
Yes, though slowly. The American Cancer Society says chemotherapy and immunotherapy combinations have clearly improved outcomes for many people. The clearest evidence comes from trials. In CheckMate 743, 14% of people given the immunotherapy drugs nivolumab and ipilimumab were alive at five years, against 6% given chemotherapy. Published registry rates cannot show that yet. That drug pair was approved in October 2020, so almost no one counted in the 2015 to 2021 SEER figures received it.
Does cell type affect mesothelioma survival?
Yes, cell type is one of the strongest influences on mesothelioma survival. Epithelioid mesothelioma grows more slowly and has the better outlook. Sarcomatoid is the most aggressive, and biphasic is a mix of both. In the CheckMate 743 trial of advanced pleural mesothelioma, five-year overall survival was 12% with nivolumab and ipilimumab in non-epithelioid disease. Chemotherapy gave 1%, and in epithelioid disease the figures were 14% and 8%. Those subgroups are small, so read them as a direction rather than a promise.
Do age and sex affect mesothelioma survival?
Yes, women with pleural mesothelioma tend to live longer than men. One SEER study followed 14,228 people diagnosed between 1973 and 2009. Five-year survival was 13.4% in women and 4.5% in men. The gap held after adjusting for age, stage, race, and treatment. Those percentages come from an older era and sit below today's rates, so read the gap and not the numbers. Age matters too, and doctors weigh it alongside stage, cell type, and how well your loved one is functioning day to day.
What is the survival rate for peritoneal mesothelioma?
Peritoneal mesothelioma, which forms in the lining of the abdomen, can carry a better outlook than pleural mesothelioma. The strong numbers come from patients selected for surgery. In a registry of 401 people who had surgery to remove visible tumor plus heated chemotherapy, median survival was 53 months. About 47% were alive at five years, and a separate report on 211 people found 41%. Everyone counted was judged fit for major surgery, and only 46% had all or nearly all tumor removed.
Are there survival rates for pericardial and testicular mesothelioma?
Not reliable ones, because both forms are extremely rare. Of US mesothelioma cases reported between 2003 and 2022, about 0.2% were pericardial, in the sac around the heart. About another 0.2% were in the tunica vaginalis, the lining around the testicle. The American Cancer Society does not publish survival rates for them. Any figures you find online come from small groups of case reports, not population statistics. Treat a precise-sounding number with caution, and ask a doctor who has treated these tumors.
Does treatment actually improve mesothelioma survival?
Yes, and randomized trials show roughly by how much. Adding the chemotherapy drug pemetrexed to cisplatin raised median survival from 9.3 months to 12.1 months. In CheckMate 743, nivolumab plus ipilimumab gave a median of 18.1 months against 14.1 months with chemotherapy. At five years, 14% were alive against 6%. In September 2024 the FDA approved the immunotherapy drug pembrolizumab with pemetrexed and platinum chemotherapy, for pleural mesothelioma that surgery cannot remove. It raised median survival from 16.1 to 17.3 months.
Does being treated at a mesothelioma specialty center improve survival?
Very likely yes, and it is one of the few things you can influence. Mesothelioma is rare, with about 2,669 US cases reported in 2022, so most oncologists see very few. The American Cancer Society advises treatment by a team in a center with a lot of mesothelioma experience. It also suggests a second opinion if time allows. The strongest survival figures in the literature all come from high-volume centers. Those centers also treat people who are fitter to begin with, so they are not the whole reason.
What can we do to give the best chance of longer survival?
The most important step is getting your loved one to a mesothelioma specialist quickly. Make sure the exact cell type is confirmed, because it guides treatment. Ask about clinical trials. The American Cancer Society says treatment in a clinical trial should be considered for any type or stage. There is no recommended screening test for mesothelioma, so acting on symptoms early is the closest thing to early detection. Helping your loved one stay strong and well fed matters too, because fitness affects which treatments they can take.
