Improving Mesothelioma Survival Rate
Mesothelioma survival rates are steadily improving due to new treatments being developed. Survival rate statistics provide more information to patients about their prognosis.
Estimating Mesothelioma Survival Time
Patients with mesothelioma are surviving longer than ever before. One key component of survival rates are the statistics that support them. These statistics help explain a patient’s prognosis and determine their outcome. They accomplish this by examining how long other patients with a similar diagnosis survive.
Underreported Factors Affecting Survival Rates
Current Survival Results
Survival rates don’t always reflect current data. Doctors examine the results of people treated in the past in order to provide patients with survival rates. These survival rates only offer a glimpse into the past, not the future.
New Treatment Options
Survival rates cannot account for new treatment options. In many cases these treatments were not available at the time the data was collected. Mesothelioma treatment options have been developing quickly through clinical trials in the past decade. Get connected to clinical trials for innovative treatments.
Survival rates can be misleading because they include patients who didn’t receive treatment or were treated by general oncologists rather than mesothelioma specialists.
Patients and families should remember that all statistics (including survival rates) have a degree of error. While mesothelioma survival rates tend to be low, overall survival rates are constantly improving due to innovative treatment options.
Doctors record survival rates at yearly intervals to provide a guideline for life expectancy. However, many patients live longer or shorter than these intervals. Mesothelioma survival rates based on location of the tumor may be misinterpreted since this disease can be easily mistaken for other types of cancer. If a patient is correctly diagnosed before the cancer reaches later stages, survival rates may not apply.
However, following the second year after diagnosis, survival rates for pleural patients drop considerably (11 percent), while survival rates for peritoneal patients only experienced a small decrease (35 percent).
This suggests it is equally hard to detect pleural and peritoneal mesothelioma early enough to effectively treat the disease. These numbers also show treatment for a peritoneal patient is more effective than treatment for a pleural patient.
Due to the rarity of pericardial mesothelioma, there are no conclusive studies to show survival rates for these patients. It is only known that the majority of patients (90 percent) with pericardial mesothelioma were diagnosed after death.
Survival rates based on stage are particularly important for determining a prognosis. There is a strong correlation between mesothelioma stage and patient life span. Patients diagnosed at the early stages of mesothelioma (with less metastasis) have significantly longer survival rates.
Mesothelioma is more often diagnosed in the later stages because of the lack of specific symptoms of mesothelioma. Survival rates at this stage are lower because the cancer is more advanced and more difficult to treat. However, there are numerous treatment options for patients at any stage. New, noninvasive treatments, like chemotherapy and radiation, are frequently being developed and improved in ongoing clinical trials.
Cell Type & Histology
Mesothelioma can develop as one of three histological cells types or variations: epithelioid, biphasic or sarcomatoid. Cell type is an important factor in survival rates. Generally, epithelioid mesothelioma has the best survival rate because it reacts better to treatment. Sarcomatoid has the poorest rate due to its ability to spread quickly.
There is a wide range of studies that show the survival rates based on the cell types of patients. Dr. David Sugarbaker completed a study in 1996 involving 120 mesothelioma patients, which illuminated how important cell type is to survival rates in patients undergoing multimodal therapy. It is important to keep in mind multimodal therapy is the most successful type of treatment for mesothelioma and other studies have varying survival rates. However, patients with an epithelioid cell type tend to do markedly better than other cell types.
Survival Rate by Cell Type After Multimodal Therapy
Survival rate statistics for biphasic cell types aren’t consistent because the ratio of epithelioid cells to sarcomatoid cells varies with each patient. However, patients with biphasic mesothelioma who have a higher percentage of epithelioid cells usually live longer. This complies with the survival rates based on epithelioid and sarcomatoid mesothelioma.
Each cell type is unique, which is why patients should find a mesothelioma specialist to treat them. Mesothelioma specialists can offer specific expertise to their patients. Get connected to a specialist using our free Doctor Match program.
