Experimental treatments, which are available when entering a clinical trial can offer a better chance to a long-term survival. However, they also involve a high element of risk and it is not guaranteed that they will work for all the patients.

Some experimental therapies, which are being investigated are promising in terms of extending the life expectancy of patients with mesothelioma. They have been proved to be successful in killing cancerous cells and include immunotherapy, gene therapy, and photodynamic therapy.

Over time, a lot of research has been done and significant treatment options have been discovered and, therefore, the prognosis for mesothelioma patients can be improved by entering a clinical trial.
