Abstract:
PURPOSE: Bone involvement is known to develop in 40-70Yo of pediatric acute leukemia. We aimed to analyze the clinical course and result of therapy in pediatric acute leukemia with bone involvement. METHODS: Twenty-seven patients diagnosed as pediatric acute leukemia at Dong San Medical Center from Jan. 1996 to Aug. 1998 were evaluated. According to bone X-ray and whole body bone scan, the patients were divided into two groups. RESULTS: Twenty-seven patients were enrolled in this study with 14 patients(52Yo) showing definite bone involvement on simple X-ray or bone scan. Mean age of patients with bone involvement was 5.5 years. Regarding the type of leukemia, 9 patients(64%) were acute lymphocytic leukemia. Ten patients(71%) out of 14 with bone involvement complained of bone pain at the involved bony site. Site of involvement was most frequent in the lower extremity. On simple X-ray, osteolytic lesion was found in 7 patients(50%), diffuse osteopenia in 2 patients(14%) and pathologic fracture in 2 patients(14%). In bone scan, radioactivity was increased in whole cases of patients with bone involvement. Thirteen patients(93%) were completely remitted by chemo-therapy, but, one AML patient died due to induction failure. CONCLUSION: Bone involvement occured in 52% of pediatric acute leukemia. Bone involvement was more frequent in male patients in the lower extremity, and osteolytic lesion was the most frequent finding on simple X-ray. There was no relevence between bone involvement and prognosis. Further study will be needed to evaluate long-term survival and prognosis. (J Korean Pediatr Soc 2000;43:806-813)
