Popis: | Signal transducer and activator of transcription 5 (STAT5) plays a key role in the malignancy of many tumors and has been identified as a therapeutic target. However, the role of STAT5A in osteosarcoma is still unclear.98 osteosarcoma patients were obtain from the Therapeutically Applicable Research to Generate Effective Treatments (TARGET). The relationship between STAT5A and clinical features was analyzed using the Wilcoxon signed-rank test and logistic regression. Kaplan-Meier method, univariate and multivariate Cox regression analyses were performed to assess the prognostic value in event-free survival (EFS) and overall survival (OS). Gene Set Enrichment Analysis (GSEA) was performed.STAT5A low expression was not linked to age, gender, tumor site, surgical approach, tumor region, histologic response, and metastasis, but was correlated with progression (OR = 5.2, P = 0.012). Kaplan-Meier survival curve showed that patients with STAT5A low expression had worse EFS and OS than those with STAT5A high expression (P 0.01). Furthermore, the multivariate analysis revealed STAT5A was an independent prognostic factor for poor OS (HR = 3.29, P = 0.0408)) and EFS (HR = 7.29, P = 0.0025). GSEA showed that the complemen, metabolism, apoptosis, interferon-gamma response, inflammatory response, Notch, Kras, reactive oxygen species, VEGF, IL-6/JAK/STAT3, IL-2/Stat5, B-cell receptor, and p53 pathways were significantly associated with the STAT5A gene.STAT5A may be a novel prognostic factor for osteosarcoma and may act as a molecular target in the treatment of osteosarcoma. |
