For example, the early diagnosis of mesothelioma is considered to be important for prognosis, and mesothelin may be useful as a blood tumour marker in the early diagnosis of mesothelioma in a mass examination [70, 71], as well as to identify genetic imbalances that could play an important role in the initial development of mesothelioma [72]. The gene discussed is MSLN; the disease is mesothelioma.
