Multidisciplinary management of osteosarcoma: experience in Hong Kong.
All pediatric osteosarcomas treated in our hospital between 1985 and 1995 were reviewed. There were 26 patients, 15 males and 11 females, aged 20 or less at diagnosis. All had limb primaries. Nineteen patients had localized disease and seven presented with metastases. Intensive multiagent chemotherapy was given both pre- and postoperatively. Most patients were treated with the Rosen T10 regimen or its modifications. Only one patient had limb salvage surgery; all others had amputation. With a median follow-up of 74 months, the 5-year disease-free survival among patients with localized disease was 65.2%. Being female and having a high 6-hour postinfusion methotrexate level with a median level greater than 700 mumol/L were good prognostic factors. Three of the seven patients with metastatic disease were alive at 21, 26, and 140 months after diagnosis. All of them had lung secondaries. Survival rates achieved in our center were comparable to those reported in literature. However, our amputation rate was high and further development in expertise for limb salvage treatment is a goal.
