What Is the Life Expectancy For Mesothelioma Patients?
Life expectancy summarizes the survival and mortality experiences in groups of people. The meaning of life expectancy is not just a hypothetical estimate of how long a person should expect to live, but the age in which members of a group can expect to pass away.
Doctors can determine an estimation of life expectancy for mesothelioma patients by observing how long other patients live after their diagnosis. The evaluation includes treatment options and success rates, along with other factors.
The estimation of life expectancy in mesothelioma patients generally requires making assumptions based on other patients. However, each case of mesothelioma is unique, making it difficult for doctors to pinpoint exactly. There are patients that live longer than their estimated life expectancy.
What Affects Life Expectancy?
Life expectancy is an important part of a patient’s prognosis, which is the outlook on how the cancer will progress. Several factors influence life expectancy. Cell type, the stage of mesothelioma, and tumor location are factors out of the control of the patient. However, controlled factors such as undergoing treatment and living a healthier lifestyle can significantly impact life expectancy.
Younger patients tend to undergo more aggressive treatments better than older patients, resulting in a longer life expectancy. However, doctors diagnose most mesothelioma patients over the age of 65.
Mesothelioma tumors contain two different cell types: epithelioid and sarcomatoid. Sometimes, tumors can include both cell types, referred to as biphasic. Epithelioid tumors start in the cells that line an organ, while sarcomatoid tumors begin in the bone or soft tissues. Patients with epithelioid tumors tend to have a better life expectancy because the tumors don’t spread as quickly and respond better to treatment.
Male mesothelioma patients have a much lower life expectancy than female mesothelioma patients. Most mesothelioma patients are men who were exposed to asbestos in the workplace. Women make up a small percentage of mesothelioma diagnoses, likely due to the occupations with higher risk of asbestos exposure being dominated by men. Exposure likely happens when women come into contact with asbestos in the home, through secondary exposure.
As the disease becomes more understood by researchers and doctors, treatment options significantly improve over time. Patients in earlier stages are better candidates for curative treatment options, while those in later stages tend to receive palliative care instead.
Patients who have peritoneal mesothelioma tend to qualify for better treatment options than those with pleural or peritoneal mesothelioma, resulting in a better life expectancy.
Doctors commonly use the stage of the cancer as a determinant of a patient’s life expectancy. The location of the cancer, where it has spread, and whether it is affecting other parts of the body typically determine the stage. The life expectancies for each stage of mesothelioma are:
How Can I Improve My Life Expectancy?
The best way to improve life expectancy is to receive the best treatment option for your specific case. Surgery alone has proven to increase the life expectancy of mesothelioma patients. An experienced specialist will be able to explore different options and recommend the best one.
The median life expectancy for stage 4 mesothelioma is around one year after chemotherapy treatment starts, compared to seven months without it.
Clinical Trials and Emerging Treatments
Traditional treatment, like chemotherapy, radiation, and surgery, aren’t always an option for some patients. Emerging treatments and clinical trials are alternative ways to improve life expectancy. Immunotherapy has also shown promising results in mesothelioma patients.
Mesothelioma Life Expectancy Without Treatment
Receiving treatment is an essential part of extending life expectancy for mesothelioma patients. However, the cancer generally advances quickly, and some patients may choose not to receive treatment.
The life expectancy for pleural mesothelioma without treatment is about eight months. Peritoneal mesothelioma patients survive about six months without treatment. However, peritoneal patients respond well to treatment and have a 50 percent chance of living longer than five years when they choose to undergo treatment.
Life Expectancy vs. Prognosis and Survival Rate
While life expectancy is an estimation of how long a patient is likely to live after a diagnosis, many people confuse it with survival rate. Doctors determine the survival rate by calculating the average of the amount of time people with the same type and stage of cancer survive.
Life expectancy takes into consideration multiple factors, rather than just the percentage of the average survival rate.
The prognosis of a cancer patient is similar to life expectancy, but involves more than an estimation of how long they can live with the disease. Prognosis takes into consideration the anticipated progression of the disease.
The life expectancy of mesothelioma patients can be rather poor. However, further research is advancing treatment options to improve the survival rate and quality of life. Learn more about mesothelioma treatment.
