Study on the Value of Liquid-based Cytology Test in the Diagnosis of Lung Cancer
Objective:To study the value of Liquid-based cytology test in the diagnosis of lung cancer.Methods:80 patients were first diagnosed in Department of Respiratory and Critical Care Medicine of People's Hospital of Xinhui district of Jiangmen city from April 2023 to March 2024,and all the patients adopted the methods of traditional bronchoscopy biopsy,brush smear cytology and brush Liquid-based cytology test.Cytology of traditional brush coventional smear(CS)was the control group,bronchoscopy Liquid-based cytology test(LCT)was the fluid base group,and bronchoscopy biopsy was the forceps group.The positive rate of lung cancer diagnosis of each group,the examination of the liquid base group and the control group,and the two groups were compared Examination results of lung cancer tissue types.Results:The positive rate of lung cancer diagnosis in the liquid base group was 40.00％(32/80),which was significantly higher than 25.00％(20/80)in the control group(P＜0.05).However,the difference between the liquid base group and the forceps group was not significant(P＞0.05).The coincidence rate of LCT was 83.33％(10/12),42.86％(6/14),and 75.00％(9/12).The coincidence rate of CS for the diagnosis of squamous cell carcinoma of lung cancer was 41.67％(5/12),the diagnostic concordance rate for adenocarcinoma was 66.67％(8/12)and 35.71％(5/14).The coincidence rate for squamous carcinoma and small cell carcinoma was higher in the control group(P＜0.05),but the difference for adenocarcinoma was not significant(P＞0.05).Conclusion:The diagnosis of lung cancer and should be used in clinical diagnosis.
