    Input: The objective of this study was to estimate the time to treatment failure and survival rate of the three‐drug combination of doxorubicin , cisplatin , and ifosfamide as primary and postoperative , adjunctive treatment for teenagers and adults with osteosarcoma ( OS ) 
    Output:
    
Conclusion This meta- analysis indicated that the abnormally expressed lncRNAs might significantly affect the survival of osteosarcoma patients .
Combined use of these lncRNAs may serve as potential novel biomarkers for the indication of clinical outcomes of osteosarcoma patients as well as the selection of adjuvant chemotherapy strategies for clinical treatment of this disease
