Prognostic role of pathologic fracture in osteosarcoma: Evidence based on 1,677 subjects
1Department of Orthopedics, The First Affiliated Hospital of Chongqing Medical University, Chongqing, China.
Introduction:
The prognostic role of pathologic fracture in osteosarcoma has not been settled down, as previous researches have reached contradictory results. This study is prepared to clarify whether pathologic fracture predicts a poor prognosis of patients with osteosarcoma.
Materials And Methods:
After completely retrieved databases including China National Knowledge Infrastructure (CNKI), PubMed, Highwire, EMBASE and Science Direct, all eligible articles were included based on inclusion/exclusion criteria. And we performed a meta-analysis to calculate the pooled prognostic role of pathologic fracture in osteosarcoma.
Results:
Finally, a total of 8 articles met the inclusion/exclusion criteria, involving 1,677 subjects. We found that the pooled hazard ratios (HRs) with 95% confidential interval (CI) of pathologic fracture in osteosarcoma for overall survival (OS) and disease-free survival (DFS) are 2.13 (1.43, 3.15) and 1.58 (1.11, 2.24), respectively.
Conclusion:
This meta-analysis demonstrated that presentation with a pathologic fracture in osteosarcoma was correlated with a poor prognosis. And pathologic fracture might be a poor predictor of survival in osteosarcoma.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
