Abstract
Context
9p loss appears a reliable and promising marker able to differentiate specific categories of patients with renal cell carcinoma associated with a worse prognosis.
Objective
The aim was to systematically evaluate relative risk of death, cancer-specific survival (CSS) and disease-free survival (DFS) among patients harboring 9p loss.
Evidence Synthesis
We found a total of 92 potentially relevant articles focused on the detection of 9p loss in patients with renal cell carcinoma and clinical outcomes of this population. Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines were employed to carry out this work. Fourteen studies resulted to be eligible for this analysis; 11 of these reported data on 5-year overall survival, six on CSS and four on DFS. An increased risk of death has been observed in patients harboring 9p loss (pooled relative risk of 3.965; 95% confidence interval [CI] 2.647–5.940, p < 0.001). Similarly, worse CSS (hazard ratio [HR] 6.776; 95% CI 3.824–12.009; p < 0.001) and DFS (HR 2.914; 95% CI 1.245–6.819; p = 0.014) have been observed in this population. Heterogeneity was significant in survival analysis, while no significant heterogeneity was observed in the CSS and DFS analyses.
Conclusions
Patients harboring chromosome 9p loss have worse clinical outcomes in terms of overall survival, CSS and DFS.
