Osteosarcoma, the most prevalent primary bone cancer, tends to relapse or metastasize quickly. Hypoxia-inducible factor-1 alpha (HIF-1α) affects tumor metabolism, differentiation, angiogenesis, proliferation, and metastasis. Many studies have investigated the possible inconsistent prognostic value of HIF-1 α. This study evaluated the correlation between HIF-1 α expression and prognosis in osteosarcoma patients. : A total of 978 patients from 12 studies were followed up. A meta-analysis was conducted on articles investigating HIF-1 α prognostic value in osteosarcoma patients. The authors excluded articles with overlapping data, duplicate data, reviews, case reports, and letters that did not provide original data. Calculation of the hazard ratios (HR) and pooled risk ratios (RR) with corresponding 95% confidence intervals were used to determine the association degree (CIs). It was determined that HIF-1 α in osteosarcoma patients had a prognostic value based on the RRs and HRs. The results showed that high HIF-1 α expression was associated with a worse prognosis when compared to low or undetectable HIF-1 α expression. HIF-1 α overexpression was found to predict poor outcomes in osteosarcomas. The present study suggests that HIF-1α is a useful prognostic biomarker to predict OS in patients with osteosarcoma.
