Prognostic Significance of Clinicopathological Factors Influencing Overall Survival and Event-Free Survival of Patients with Cervical Cancer: A Systematic Review and Meta-Analysis
Background: Cervical cancer (CC) is the most frequent type of cancer among women and its poor prognosis is a main concern, while the prognostic factors for CC have still remained controversial. We conducted this systematic review and meta-analysis to identify the prognostic significance of clinicopathological factors, influencing overall survival (OS), and event-free survival (EFS) of CC patients. Material/Methods: The electronic databases of PubMed, EmBase, and the Cochrane library were systematically searched for identification of eligible studies published until June 2021. The pooled hazard ratio (HR) with 95% confidence interval (CI) were calculated using the random-effects model. Sensitivity and subgroup analyses and assessment of publication bias were also conducted. Results: We selected 140 studies that involved 47 965 patients for the meta-analysis. The results revealed that age, cell type, depth of tumor invasion, the International Federation of Gynecology and Obstetrics stage, hemoglobin level, histological grade, leukocytosis, lymph node involvement, lymph-vascular space invasion, neutrophil-tolymphocyte ratio, parametrial invasion, platelet-to-lymphocyte ratio, resection margin, squamous cell carcinoma antigen level, thrombocytosis, tumor grade, tumor size, and tumor volume were clinicopathological factors influencing OS and EFS of CC patients (P<0.05). Conclusions: This study comprehensively identified the prognostic significance of clinicopathological factors, influencing OS, and EFS of CC patients. However, further large-scale prospective studies should be conducted to verify our findings and develop more accurate prognostic models for CC.
