Four-year-old Oscar Knox is currently in America after suffering a setback in his battle against neuroblastoma, which causes tumours to develop in the stomach, spine, chest and neck, but can also spread to other parts of the body.
It is an aggressive childhood cancer which could kill him.
Oscar's parents were able to make the journey to Philadelphia after they managed to raise £250,000 towards immunotherapy thanks to a Twitter campaign which went global.
But on Wednesday Stephen and Leona Knox were told that the specialist treatment was no longer an option as Oscar is suffering from a heart problem. He is currently in intensive care.
"Oscar fighting harder than he's ever fought before. It's working, things slowly moving in right direction!" his parents tweeted.
In his hometown big names in show-business and sport, including Belfast Olympic boxers Paddy Barnes and Michael Conlon, turned out at the Europa Hotel for a special fundraising ball to rally support for the little boy's continuing fight.
"Everyone knows Oscar is such a fighter, he had a good night last night so everything seems to be looking up," explained Sarah McCarthy who is a friend of the family and helped organise the ball.
"It's really just to raise as much money as possible for whatever treatment that Oscar may need now or in the future you know, he has a very bright future ahead of him and we want to make sure that we raise a lot of money for him and his family," she added.
"It's great to have Olympians here to support Oscar," Pat McCarthy, Oscar's grand uncle, said.
John Linehan, aka 'May McFettridge', said the campaign reminds us of what is important.
"It's alright for us you know, we can go home our kids are fine, that's what I want everybody to do tonight, just think about the family, think about the child you know, we can go home to ours... so it's a hard old thing but we'll try and raise as much as we can tonight," he said.
