Researchers report aspects of mesothelioma survival rates

On November 5, 2010, the Journal of Thoracic Oncology reported a study done by University of Rochester researchers looking for significant factors associated with longer life expectancy of mesothelioma patients. Spanning decades of case studies, researchers found several factors associated with life expectancy and survival rates of mesothelioma victims.

Mesothelioma is a rare cancer with no known cure. Aggressive mesothelioma treatments include surgery, radiotherapy, chemotherapy and rehabilitative therapies. A combination of treatments is typical for mesothelioma cases. However, many mesothelioma patients choose palliative treatments rather than fighting the cancer directly. Palliative care focuses on pain management and quality of life.

Mesothelioma cancer is specific to the lining of lungs and other abdominal cavities. Most typically associated with the toxic chemical asbestos, mesothelioma can begin to develop after asbestos fibers are inhaled. These fibers begin a mutation process which results in growth and spread of irregularly patterned tumors.

Development times for mesothelioma are characteristically long. Often patients do not demonstrate signs or symptoms until decades after exposure to asbestos. Many mesothelioma patients have no idea they were exposed to the toxic fibers until they have been diagnosed with mesothelioma, and the symptoms are easily assumed to be that of pneumonia or other treatable respiratory illnesses. These factors make mesothelioma difficult to detect early.

The study by University of Rochester looked at 9,701 mesothelioma cases diagnosed between 1973 and 2006. Results proved survival rates dropped drastically as time extended from original diagnosis. Survival rates were 55% after six months, 33% after one year and 5% after five years.

Factors proving positive in patient survival were varied. Female patients and patients in younger years had longer life expectancies. Tumor grade and histology also played a part in survival rates with lower tumor grade and epithelioid histology (a more common structure of mesothelioma cells) being associated with higher survival rates. Cancer-direct surgery and radiotherapies also proved to have greater impact on patient’s potential for longer life.

The Department of Radiation Oncology at James P. Wilmot Cancer Center at University of Rochester is one of the nation’s leading research institutes in cancer and radiation technology. Their mission “is to cure cancers when possible while always aiming to improve the quality of life of patients, to advance the science of cancer therapy through clinical and basic research, and to train young oncologists to carry these goals forward.”
