Leukaemia sufferer Joshua Gillespie-Wong, the young boy whose plight sparked a worldwide donor appeal, has died. Relatives held a funeral service for the four-year-old boy at the Hong Kong Funeral Parlour in North Point yesterday. In a newspaper notice, his family announced: 'Sandie, Willie and Natasha thank everyone who helped Joshua live such a full and active life, filled with love, joy and fun.' A worldwide appeal was launched to find a bone marrow donor for Joshua's Eurasian tissue type after he was diagnosed in early 1996. But doctors advised the Discovery Bay family not to go ahead with the transplant after a donor was found in the United States in September, saying it was too risky to operate. Senior medical officer Dr Godfrey Chan Chi-fung, from the paediatrics ward at Queen Mary Hospital, said Joshua had died at the hospital on December 4. 'He was a lovely and very brave and active boy,' Dr Chan said 'Like many children with cancer, he matured much faster than other children his age. 'We told his parents that even though a donor had been found, there was a strong chance an operation would be risky,' said Dr Chan, who had helped look after Joshua since he was first admitted to the hospital in 1996. Joshua's Scottish mother Sandie Gillespie-Wong, father Willie Wong Tsang-ki and older sister Natasha began an appeal for a donor shortly afterwards. A relapse at Easter meant the transplant could not be carried out. A memorial service will be held at St John's Cathedral, Central, on Wednesday.
