The aim of this research was to investigate the clinical role and prognostic value of CD117 expression assessed immunohistochemically in lung carcinoma through a comprehensive meta-analysis in which 27 publications were acquired and 2645 patients were ultimately analysed. Statistical analysis and corresponding plots were performed using STATA version 12.0. Publication bias was assessed by Begg’s funnel plots and Egger’s test. Pooled HR and its 95% CI (HR = 1.53, 95% CI: 1.13-2.07, p = 0.007) for overall survival of patients indicated a poor prognostic value for CD117 expression in lung carcinoma, which was accompanied by heterogeneity and publication bias. In the subgroup analysis, there was strong evidence that could support an association between CD117 expression and poor prognosis in NSCLC patients (HR = 2.03, 95% CI: 1.41-2.90, p < 0.001; heterogeneity: I2 = 41.9%, c2 = 15.49, p = 0.078). Multivariate analysis also revealed consistent results in high-quality studies with reported HRs (HR = 2.16, 95% CI: 1.67-2.79, p < 0.001), and Asian patients (HR = 2.12, 95% CI: 1.45-3.10, p < 0.001). The correlations between CD117 expression and age, clinical stage, TNM stage, lymph node metastasis, or histology were not statistically significant. In conclusion, CD117 expression might be a potential marker for predicting poor prognosis, faster tumour growth, and early lymph node metastasis in NSCLC.
