ABSTRACT
Lung cancer is the leading cause of cancer-related deaths globally. Early detection of lung cancer can lead to more effective treatment and improved survival. Circulatory abnormal cells (CACs) with specific chromosomal variation may be used to diagnose lung cancer and to differentiate benign from malignant nodules. The value of CAC in precancer diagnosis, however, remains controversial. In this study, a systematic review and meta-analysis are conducted to clarify the diagnostic value of CAC in early-stage lung cancer. A systematic literature search was conducted using the following medical topic title terms and text-free words "circulating genetically abnormal cells", "CACs", "liquid biopsy", "early lung cancer", "non-small cell lung cancer", "diagnostic accuracy", "sensitivity" and "specificity" in Science Direct, CNKI and Wanfang databases, respectively. Sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and area under the curve were analyzed by STATA15.0 (MP) software. Deek funnel plots were used to assess potential publication bias. Heterogeneity was tested using the I2 statistic and the Cochrane Q test. 7 major studies were included in this meta-analysis, and a total of 53728 participants were analyzed. In the diagnosis of early lung cancer, CAC had pooled sensitivity, specificity, and receiver operating characteristics of 0.80 (95% CI 0.73-0.86), 0.85 (95% CI 0.69-0.94), and 0.87 (95% CI 0.84-0.90). The combined positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and diagnostic score were 23.36 (95% CI 7.33-74.46), 5.42 (95% CI 2.37-12.43), 0.23 (95% CI 0.16-0.35) and 3.15 (95% CI 1.99-4.31) respectively. Publication bias was not detected. The CAC is effective at detecting lung cancer in its early stages.
