More than 40 children and teenagers who survived potentially fatal diseases, after undergoing bone marrow transplants at Queen Mary Hospital, gathered yesterday for the first time to celebrate. The young people, from Hong Kong, Macau and the mainland, are among the hospital's 91 former paediatric patients who have recovered over the past 12 years after receiving the transplants. Fifty-two other patients have died from transplant-related complications and cancer. The recovered patients were given 'young warrior' awards, and another 13 donors were hailed as 'benevolent ambassadors' at a celebration party organised by the University of Hong Kong's Department of Paediatrics and Adolescent Medicine and the Children's Centre for Cancer and Blood Diseases. Ha Shau-yin, the University of Hong Kong's clinical associate professor in paediatrics, said apart from celebrating the patients' recovery, they also hoped to draw more bone marrow donors. 'The youngest donor recorded at the hospital is as young as two years old. We hope to spread the message that not only adults can be potential bone marrow donors,' he said. Dr Ha said the young patients made up about 15 per cent of the hospital's 940 transplant cases.
