Abstract
Background: Malignant pleural mesothelioma (MPM) is a rare cancer of the respiratory system that rarely metastasizes to the brain. We report a case of sarcomatoid MPM (SMPM) managed with Stereotactic radiosurgery (SRS) to achieve intracranial tumor control and improve neurological symptoms.Illustrative case: This 67-year-old female patient underwent SRS twice in order to treat a total of 15 brain metastases. One-month follow-up imaging after the first SRS demonstrated local tumor response and seven tumors with symptomatic vasogenic edema that responded to initial corticosteroids followed by bevacizumab. At a three-month follow-up after the first procedure, eight new tumors were detected and required repeat SRS. Although sustained tumor control resulted in improved neurological function, the patient subsequently expired from systemic disease progression 12 months after initial diagnosis and six months after initial SRS for brain metastases despite the concurrent use of systemic immunotherapy and systemic chemotherapy.Conclusions: Although SRS provided overall tumor control of metastatic brain disease, further advances in systemic therapies will be needed to improve survival in this aggressive rare cancer.
