Alex Trebek says he's undergoing chemotherapy again after his "numbers went sky high"

Good Morning America

The Jeopardy! host tells Good Morning America that doctors have decided to have him undergo another round of chemo after he lost a large amount of weight and his numbers sky rocketed right after finishing his first round of treatment for stage 4 pancreatic cancer. “I was doing so well," Trebek said in an interview that aired this morning. "And my numbers went down to the equivalent of a normal human being who does not have pancreatic cancer. So we were all very optimistic. And they said, 'Good, we're gonna stop chemo, we'll start you on immunotherapy.' I lost about 12 pounds in a week. And my numbers went sky high, much higher than they were when I was first diagnosed. So, the doctors have decided that I have to undergo chemo again and that's what I'm doing."
