Mesothelioma Information

Detailed Mesothelioma Prognosis Statistics

Prognosis for mesothelioma is difficult to assess consistently when looking at different research studies because there are often large differences in the time before diagnosis and the rate of disease progression.  Median survival has been reported as 16 months for patients with malignant pleural disease and 5 months for patients with extensive disease.  However, the National Cancer Institute (NCI) cautions that one must be very careful in relying on these statistics too heavily because of these inconsistencies between studies.  This information applies to pleural mesothelioma prognosis only and not to other mesotheliomas like peritoneal and pericardial.  It is clear however that mesothelioma is an incurable disease at this time.  For detailed mesothelioma prognosis information see this NCI mesothelioma prognosis statement written for health professionals.

Another way to gather more detailed information is to search and read medical journal articles that discuss prognosis.  These are the types of articles that your doctor reads to get a better understanding of prognosis in mesothelioma patients.  The best and easiest way to find medical journal articles is to use PubMed, the massive medical database of the National Library of Medicine.  See this page for more information on PubMed.

What Factors Affect Prognosis in General?

This is a useful general discussion of prognosis, but is not specific to mesothelioma.  A prognosis gives an idea of the likely course and outcome of a disease.  Many factors affect a person’s prognosis, including the type, location, and stage of the disease, as well as the person’s age, general health, and response to treatment.  Survival rates indicate the percentage of people with a certain type and stage of cancer who survive the disease for a specific period of time after their diagnosis.  Survival rates are based on large groups of people.  Doctors cannot be certain about the outcome for a particular patient.  In fact, a person’s prognosis may change over time.

People facing cancer are naturally concerned about what the future holds.  Understanding cancer and what to expect can help patients and their loved ones plan treatment, think about lifestyle changes, and make decisions about their quality of life and finances.  Many people with cancer want to know their prognosis.  They may ask their doctor or search for statistics on their own.

A prognosis gives an idea of the likely course and outcome of a disease—that is, the chance that a patient will recover or have a recurrence (often incorrectly said as re-O-cur).  Many factors affect a person’s prognosis.  Some of the most important are the type and location of the cancer, the stage of the disease (the extent to which the cancer has metastasized, or spread), or its grade (how abnormal the cancer cells look and how quickly the cancer is likely to grow and spread).  Other factors that may also affect the prognosis include the person’s age, general health, and response to treatment.  When doctors discuss a person’s prognosis, they carefully consider all factors that could affect that person’s disease and treatment, and then try to predict what might happen.  The doctor bases the prognosis on information researchers have collected over many years on thousands, or even tens of thousands of people with cancer.  When possible, the doctor uses statistics based on groups of people whose medical situations are most similar to that of an individual patient.

The doctor may speak of a favorable prognosis if the cancer is likely to respond well to treatment.  The prognosis may be unfavorable if the cancer is likely to be difficult to control. It is important to keep in mind, however, that a prognosis is only a prediction.  The doctor cannot be absolutely certain about the outcome for a particular patient.

Survival rates indicate the percentage of people with a certain type and stage of cancer who survive the disease for a specific period of time after their diagnosis.  Often, statistics refer to the 5-year survival rate, which means the percentage of people who are alive five years after diagnosis, whether they have few or no signs or symptoms of cancer, are free of disease, or are having treatment.  Survival rates are based on large groups of people.  They cannot be used to predict what will happen to a particular patient.  No two patients are exactly alike, and treatment and responses to treatment vary greatly.

Cancer patients and their loved ones face many unknowns.  Some people find it easier to cope when they know the statistics.  Other people find statistical information confusing and frightening, and they think it is too impersonal to be of use to them.  The doctor who is most familiar with a patient’s situation is in the best position to discuss the prognosis and to explain what the statistics may mean for that person.  At the same time, it is important to understand that even the doctor cannot tell exactly what to expect.  In fact, a person’s prognosis may change if the cancer progresses, or if treatment is successful.

Seeking information about the prognosis is a personal decision.  It is up to each patient to decide how much information he or she wants and how to deal with it.
