Alex Trebek is going back on chemotherapy for his late-stage pancreatic cancer, the renowned gameshow host said in a video update released on Tuesday.
Trebek first revealed his diagnosis in March of this year. Despite the dire prognosis, the 78-year-old host announced a few months later that his chemotherapy treatment had gone astoundingly well — with his doctors saying that he was in "near remission."

Soon, Trebek was back at work and taping the new season of "Jeopardy!" as scheduled.
"One of the things I've learned in the past six months is that the course of pancreatic cancer treatment is not a straight-forward affair," Trebek said in his Monday update.
The host said that the decision for him to end his chemo treatments and begin immunotherapy over the summer had been "premature," and over-optimistic. Soon, doctors were telling him that his numbers had "gone south" again.
"It appears I will be having more chemo treatments ahead of me," Trebek said. The host said that he expects good results again from the chemo, and asked his audience to keep him in their thoughts.
