What Are the Three Subtypes of Mesothelioma?

[MUSIC PLAYING] So these three subtypes of mesothelioma-- again, the sarcomatoid, the mixed, and the epithelial-- have different clinical courses, if you will. They express themselves within the patient in a different manner. And it's important to understand which one of these three the physician is dealing with in any particular patient. And that's because each tumor, such as sarcomatoid, is a very, very aggressive tumor that needs aggressive therapy and needs it more urgently than the other two types. The mixed type of tumor also has a more aggressive clinical course. And we find that, again, in this situation, we need to act more urgently and more aggressively. Now, the epithelial subtype of mesothelioma, again, while it is epithelial mesothelioma, and as one here is the term "mesothelioma," obviously, we are still moving forward in an urgent fashion. Nevertheless, our options for therapy are greater because it's been shown that this cell type does, indeed, respond to more of a variety of treatment strategies. [MUSIC PLAYING]
