The objective of this study is to evaluate whether high-dose chemotherapy is more efficacious than standard-dose chemotherapy in the treatment of primary well-differentiated osteosarcoma. The Cochrane systematic evaluation method was adopted. A database search was conducted in MEDLINE, Embase, OVID, the Cochrane Central Register of Controlled Trials database and the Chinese Biomedical Literature CD-ROM Database.

The objective of this study is to evaluate whether high-dose chemotherapy is more efficacious than standard-dose chemotherapy in the treatment of primary well-differentiated osteosarcoma. The Cochrane systematic evaluation method was adopted. A database search was conducted in MEDLINE, Embase, OVID, the Cochrane Central Register of Controlled Trials database and the Chinese Biomedical Literature CD-ROM Database. The quality of the included studies was jointly evaluated by two reviewers, and homogeneous studies were included for meta-analysis. A total of five studies were included in this meta-analysis, with 1,415 subjects with primary, nonmetastatic, well-differentiated osteosarcoma in the limbs. No statistically significant differences were found between the high-dose chemotherapy group and the low-dose group in 5-year event-free survival [RR 1.04, 95 %CI ], 5-year overall survival [RR 1.02, 95 %CI ], local recurrence rate [RR 0.90, 95 %CI ], proportion of subjects with good histological response [RR 0.93, 95 %CI ], or limb salvage rate [RR 0.97, 95 %CI ]. A statistically significant difference was observed in the 5-year event-free survival between the subjects with good histological response to preoperative chemotherapy and the subjects with poor histological response [RR 1.55, 95 %CI , P < 0.001]. High-dose chemotherapy did not show superior efficacy to low-dose chemotherapy in the treatment of primary well-differentiated osteosarcoma. Further high-quality randomized controlled trials are needed to provide additional reliable evidence for our observation.收起
