• Objective： The aim of this study was to identify prognostic factors and imply the appropriate management for lo- cal recurrent osteosarcoma. Methods： The clinical records of 60 patients with local recurrence osteosarcoma were reviewed between January 2002 and December 2010. The mean followed-up time for these patients was 49.1 months （range 13 to 143 months）. The factors of age, gender, tumor site, tumor size, surgical procedure, neoadjuvant chemotherapy, frequency of primary postoperative adjuvant chemotherapy, lung metastasis, metastasis of other sites （except for lung） and treatment after local recurrence were selected as the measurements for this analysis. Kaplan-Meier method was used to measure the overall survival and post-recurrence survival. The univariate analysis was used to determine the prognostic factors related with survival by Log-rank test. The COX proportional-hazard regression model was used to analyze the correlation between the prognostic factor and the survival. Results： The median post-recurrence survival and overall survival of 60 patients were 32 months （95% confidence interval： 16.2-47.8） and 55 months （95% confidence interval： 39.3-70.7） respectively. The 2- and 3-year cumulative survival rates were 81.7% and 55.4%, respectively. The Log-rank univariate analysis showed that age, gender, tumor size, metastasis of other sites （except for lung） and treatment after local recurrence were associated with the prognosis of osteosarcoma with local recurrence （P 〈 0.05）. The Cox regression analysis revealed that gender （P = 0.016）, metastasis of other sites （except for lung, P = 0.017） and treatment after local recurrence （P = 0.028） were the independent prognostic factors of osteosarcoma with local recurrence. On the other hand, the prognosis of local recurrent osteosarcoma was not associated with tumor site, surgical procedure, frequency of primary postoperative adjuvant chemo- therapy, neoadjuvant chemotherapy and lung metastasis （P 〉 0.05）. Conclusion： The independent prognostic factors for local recurrent osteosarcoma were the metastasis of other site （except for lung） and the treatment after local recurrence. The aggressive surgical treatment for local recurrence and distant metastasis could effectively improve the survival of local recurrent osteosarcoma.
