welcome to Howtodoanything, today we will be talking about Mesothelioma a rare, aggressive form of cancer that develops in the lining of the lungs, abdomen, or heart. which is Caused by asbestos, mesothelioma has no known cure and has a very poor prognosis.so below are the Mesothelioma causes, Symptoms, Diagnosis, Risk Factors, Treatment, Prognosis, Life expectancy.
What is Mesothelioma?
Mesothelioma is caused by asbestos exposure. Over time, asbestos causes tumors to develop in the linings of the lungs, abdomen or heart. Risk factors associated with exposure to asbestos can be occupational, environmental or secondhand.
Types of Mesothelioma
Pleural mesothelioma is a rare and malignant cancer caused by asbestos. Mesothelioma tumors form in the pleura, a thin membrane of cells that line the lungs and chest wall.
Peritoneal mesothelioma is cancer found in the peritoneum, a thin membrane surrounding the abdomen. Caused by exposure to asbestos, peritoneal mesothelioma is extremely rare, and the prognosis is generally poor.
Mesothelioma Prognosis and Treatment Cost
Mesothelioma treatment costs can be significant, regardless of a patient’s prognosis. Some insurance companies may not cover the costs of diagnostic tests, clinical trials, or other experimental therapies.
|Mesothelioma Diagnosis & Treatment Costs||Approximate Cost Range|
|Surgery – Lobectomy/Pneumonectomy (removal of part or all of a lung)||$13,000 – $17,000|
|Radiation||$7,000 – $12,000|
|Chemotherapy – Pemetrexed||$37,000 – $50,000|
|Hyperthermic Intraperitoneal Chemotherapy (HIPEC)||$700 – $1,000|
Average life expectancy for mesothelioma patients is 12 to 21 months. How long a patient lives depends on several factors including age, stage of the disease, and overall health. Approximately 40 percent of patients live past one year; 9 percent live longer than 5 years.
A malignant mesothelioma is an aggressive form of cancer whose symptoms typically don’t show up until later stages. Therefore, life expectancy for mesothelioma patients is generally short, especially without treatment.
Factors Affecting Life Expectancy
The life expectancy of a mesothelioma patient is a complex thing to determine, as it depends on a variety of factors.
An early diagnosis can improve life expectancy significantly. When diagnosed at an early stage (Stage I or Stage II), there is little or no spreading, and treatments are likely to be more effective. However, at Stages III and IV the mesothelioma has expanded beyond the initial location, which makes treatment more difficult.
Another big factor that can affect life expectancy is where the mesothelioma develops. Historically, patients with pleural mesothelioma have had a slightly longer life expectancy than those with peritoneal mesothelioma, while patients diagnosed with peritoneal mesothelioma have a very short life expectancy. However, in recent years, the life expectancy of patients diagnosed with peritoneal mesothelioma has improved, due to the development of more effective treatments.
Generally, older mesothelioma patients have shorter life expectancies, mostly because they are in poorer health and the disease is likely to be at a later stage. One study showed that individuals diagnosed with pleural mesothelioma before the age of 65 lived almost 4 months longer than those diagnosed at age 65, and more than 8 months longer than those diagnosed at age 75 or older.
|Pleural Mesothelioma Life Expectancy
by Age at Diagnosis
|Up to 65 years||12 months|
|65+ years||8 months|
|75+ years||< 4 months|
Mesothelioma can be categorized into three different cell types: epithelioid, sarcomatoid, and biphasic (a mixture of both epithelioid and sarcomatoid cells). Typically, those with epithelioid mesothelioma have a significantly longer life expectancy than those with sarcomatoid mesothelioma, while those with biphasic mesothelioma have a life expectancy in-between.
|Epithelioid||19 months||54 months|
|Biphasic||13 months||4.6 months|
|Sarcomatoid||8 months||Not enough data|
Fewer women have mesothelioma than men, mostly due to occupational differences and risk of asbestos exposure, and life expectancy in women diagnosed with mesothelioma tends to be longer than for men. In general, women diagnosed with mesothelioma live about 5.5 months longer than men with mesothelioma.
Patients diagnosed with early-stage mesothelioma may be eligible for an aggressive treatment program, such as involving surgical removal of the tumor combined with chemotherapy or radiation. The surgery is an extensive procedure, so the patient must be in generally good health and not advanced in age.
Patients who can withstand such aggressive treatments often have a better life expectancy and a chance at long-term survival beyond five years. When developing a treatment program, the oncologist will assess the patient’s health and ability to undergo such mesothelioma treatments.
After a patient is diagnosed with mesothelioma, surgery is one of the standard forms of treatment used to remove tumors, providing relief from symptoms and possibly leading to long-term survival. mesothelioma Surgery is not recommended for all mesothelioma patients, however, especially if they are in poor health or are diagnosed at a late stage.
