New Research Points to Poor Prognosis with this Mesothelioma Subtype, According to Surviving Mesothelioma

Scientists say a subset of patients with epithelioid mesothelioma – the type of that is usually most responsive to treatment – may face as big a challenge as those with biphasic or sarcomatoid.

Mesothelioma Survival Impacted By Microscopic Differences

Mesothelioma Subtypes and Survival

Our results indicate that pleomorphic subtype is a predictor of poor prognosis.

Doctors in Croatia say not all types of epithelioid mesothelioma respond to treatment in the same way. Their study of microscopic (histological) differences in mesothelioma subtypes is the subject of a newly posted article on the Surviving Mesothelioma website. Click here to read it now.

Researchers at the University of Zagreb School of Medicine analyzed the subtle differences in the tumor cells of 108 mesothelioma patients between 2000 and 2010. They found that those with a particular subtype of epithelioid mesothelioma carried as poor a prognosis as mesothelioma varieties that are usually considered less treatable.

“Our results indicate that pleomorphic subtype is a predictor of poor prognosis and support classifying it with sarcomatoid or biphasic malignant pleural mesothelioma,” writes Dr. L. Brcic, lead author on the paper.

The study, published in the international pathology journal Virchows Archiv, found the pleomorphic subtype in 5 of 98 epithelioid mesothelioma patients.

“It is important for patients and families to understand what histological subtyping means because it can have a major impact on their diagnosis, their treatment, and, ultimately, their outcomes,” says Surviving Mesothelioma Managing Editor, Alex Strauss.
