PRESENTER: So they [INAUDIBLE] better understand what the PGTKs are, you need to learn a little bit more about traditional chemotherapy, what the PGTKs are, and how they work, and finally their future potential and current limitations.

To understand why it's so common, so effective, we need to learn what it is, how it works, and why it has such horrible side effects.

Now that we know a little bit more about traditional chemotherapy, we may move on to the new method, the precision-guided tumor killers.

Having learned what the PGTKs are and how they work, we may now focus on why they are better than traditional chemotherapy.

Having learned about the new system-- looking back, we've learned a little bit more about traditional chemotheraphy. We've learned about the system, the PGTKs, and their future potential and current limitations.
