He elaborated why he was suprised in the rest of the video. Here is the quote from Twitter from the Imugene account.

"What we've seen in bile duct cancer has been quite surprising... This is a disease I've treated for 40 years. When someone has stage four, widespread disease, usually their lifespan is in months, and usually, #chemotherapy and #radiation don't work. In our trial, patients had to have failed chemotherapy to enter. To have a patient that is actually now disease-free, all the #cancer is gone, and has been without treatment for over a year and still disease-free.
