Alex Trebek, host of Jeopardy, has good news to share:  He's in "near remission,"  according to doctors.  Some of the tumors have shrunk by more than 50%.  The state 4 pancreatic cancer has a 9 percent survival rate.  "The doctors said they hadn't seen this kind of positive result in their memory," Trebek said.  It doesn't mean he's totally out of the woods yet, but he shed tears of joy when he got the good news.  He credits well wishes from fans and friends around the world.  He still has more treatments to go through, of course, but this news must change his whole outlook.
