Italian Pathologists Find Promise for Better Mesothelioma Diagnosis in Genetic Test, According to Surviving Mesothelioma

New research suggests that a test for the BRCA-1 associated protein 1 (BAP1) gene may offer a better way to distinguish mesothelioma from look-alike conditions.

Scientists from multiple Italian hospitals and universities have just released their findings on the effectiveness of a BAP1 gene test to identify mesothelioma. As Surviving Mesothelioma reports, the results are promising. Click here to read the full story.

Doctors with the University of Brescia and five other Italian medical centers measured BAP1 expression in 266 patients with either mesothelioma (212), benign mesothelial tumors (12), or reactive mesothelial proliferations (42).

“BAP1 immunostain represents an excellent biomarker with an unprecedented specificity (100%) in the distinction between benign and malignant mesothelial proliferations,” writes Dr. Marta Cigognetti, primary author of the study.

According to the report in Modern Pathology, BAP1 was expressed in every one of the benign mesothelial conditions whereas it was only present in about a third of the mesothelioma cases.

“This study suggests that BAP1 staining is a test patients may want to ask about if they have some type of mesothelial condition that could potentially be mesothelioma,” says Alex Strauss, Managing Editor of Surviving Mesothelioma.
