Malignant Mesothelioma is a tumor associated with exposure to mineral fibers such as asbestos and erionite. 1 In spite of stringent regulations introduced in the 1970s and 80s to limit asbestos exposure, the incidence of Malignant Mesothelioma reached 3,200 cases per year in the US in 2003 and it has remained stable since then. 2 The incidence of Malignant Mesothelioma has also sharply increased worldwide over the past 50 years. 1
Malignant Mesothelioma is an almost uniformly fatal malignancy. 1
While early detection is associated with better responses to therapy and prolonged survival 3 over 90% of Malignant Mesotheliomas are diagnosed at a late stage, when survival may only be extended by ~11 weeks with the standard of care. 3 Thus, to make an impact on the disease, there is a critical need to understand etiology and develop diagnostics for early detection of Malignant Mesothelioma, particularly in high-risk cohorts. There is a long latency of 20-60 years between initial exposure to mineral fibers and Malignant Mesothelioma development, which provides opportunities for prevention, early detection or intervention at the early stages of disease, provided that interventions and reliable biomarkers for exposure and early detection are available. 1
Malignant Mesothelioma can appear in several areas of the body:
- Pleura - The most frequently occurring type of Malignant Mesothelioma. The tumor affects the pleural lining, which is a thin layer of tissue that lines the chest and chest wall. About 75% of all Malignant Mesotheliomas diagnosed are pleural based.
- Peritoneum - The peritoneum is a lining of cells surrounding the abdominal cavity. About 20 - 25% of Malignant Mesotheliomas are peritoneal.
- Pericardium - The tumor invades the pericardial lining that surrounds the heart. This is a very rare type of Malignant Mesothelioma.
- Testes (in males) - This extremely rare form of Malignant Mesothelioma affects the membrane that surrounds the testes.
Dr. Carbone’s research aims at finding ways to easily diagnose Malignant Mesothelioma in extremely early stages, even before an individual experiences symptoms of the disease. Simple blood and saliva tests are being developed to identify individuals at risk of developing mesothelioma and some other types of cancer associated with a genetic alteration of BAP1. By detecting at-risk individuals sooner, and identifying their cancer at the earliest possible phase, there is hope for longer, more comfortable life, as well as hope for an eventual cure.
