A number of studies have investigated the relationship between fibroblast growth factor receptor1 (FGFR1) gene copy number and survival in non-small cell lung cancer (NSCLC) patients. However, conclusions reported by different parties seem to be inconsistent, especially regarding the differences among different histopathologic subtypes. To derive a more precise estimate of the prognostic significance of FGFR1 gene copy number, we have reviewed published studies and carried out a meta-analysis.The meta-analysis was conducted in accordance with PRISMA guidelines. The required data for estimation of individual hazard ratios (HRs) for survival were extracted from the publications and an overall HR was calculated.We identified 6 eligible studies, all dealing with NSCLC. The global quality score ranged 32.5-80%, with a median of 53.33%. For FGFR1 amplification in three studies including differed according to histological type, the overall RR was 0.86 which 95% confidence interval (CI) was 0.75 to 0.99 and P value was 0.048. Combined HR for the six evaluable studies was 1.17 (95% CI: 0.95 to 1.43). In the subgroup of squamous cell lung cancer (SQCC), the combined HR was 1.24 (95% CI: 0.89 to 1.73). For the Asian populations' studies, the combined HR was 1.67 (95% CI: 1.1 to 2.52).FGFR1 amplification significantly was more frequent in SQCC. FGFR1 was not associated with poorer survival in patients with NSCLC. Furthermore studies will be needed in terms of survival implications. |
