    Abstract:
    BACKGROUND: The objective of this report was to estimate long-term outcome and prognostic factors in adult patients with high-grade osteosarcoma. The intended therapeutic strategy included preoperative and/or postoperative chemotherapy as well as surgery of all operable lesions. PATIENTS AND METHODS: We reviewed the clinical data of 36 newly diagnosed adult patients (aged 19-82, average 37.5, median 28.5 years) with high-grade osteosarcoma of the trunk or limbs evaluated by a multidisciplinary team and treated between 1999 and 2010 in Brno. Forty-five percent of patients were over thirty, more than 36% over forty. Thirty-one percent of patients had metastasis at the time of diagnosis. Demographic parameters, tumor-related and treatment-related variables included possible prognostic factors and their impact on response, overall survival (OS) and event-free survival (EFS) were analyzed. RESULTS: All the patients were followed up after treatment. Seventy-three percent of patients were poor responders to chemotherapy. Sixteen patients are alive, and twenty patients died. The survival time ranged from 2 to 177 months (average 45 months, median survival 23 months). The 5-year OS of all patients was 52.4%. OS of patients without metastasis was 68.12%, while 2-year OS with metastasis was 26% only. 5-year EFS was 38.7%. Univariate analysis revealed that the prognosis of adult osteosarcoma patients was significantly related to distant metastasis (p = 0.006), surgical stage (p = 0.00582), serum alkaline phosphatase (ALP) level (p = 0.00841) and serum lactatdehydrogenase (LD) level (p = 0.047). The other analyzed prognostic factors including age had no statistically significant influence on outcome of osteosarcoma in adult patients. CONCLUSION: The prognosis of osteosarcoma in adult patients was significantly correlated to surgical stage, distant metastasis, serum ALP and LD.
