改良胸膜活检术联合生物标志物等对不明原因胸腔积液的诊断价值

目的 探讨改良胸膜活检术联合生物标志物、细胞学检查在不明原因胸腔积液中的诊断价值.方法 对216例胸腔积液患者的临床资料进行回顾性分析,其中结核性胸腔积液(结核组)106例,恶性胸腔积液110例(恶性组).所有患者均行改良胸膜活检术检查,胸腔积液细胞学检查,胸腔积液腺苷脱氨酶(ADA)、癌胚抗原(CEA)及乳酸脱氢酶(LDH)检测以及血CEA检测.统计胸膜活检术的确诊率,比较两组胸腔积液的ADA、CEA、LDH以及血CEA、胸腔积液CEA/血CEA水平.结果 216例患者共进行了241次胸膜活检穿刺,首次穿刺取材成功率94.9％ (205/216),首次穿刺成功的胸膜活检材料病理结果有诊断价值的占58.8％ (127/216),总确诊率65.3％(141/216),不良反应发生率为5.8％ (14/241).结核组细胞学检查肿瘤细胞阳性0例,恶性组细胞学检查肿瘤细胞阳性率54.5％(60/110);恶性组中胸腔积液CEA、LDH、血CEA及胸腔积液CEA/血CEA水平及阳性率均显著高于结核组,而胸腔积液ADA水平以及阳性率显著低于结核组,差异均有统计学意义(P＜0.01).结论 改良胸膜活检术、胸腔积液细胞学、胸腔积液生物标志物在单独辅助诊断胸腔积液时均具有一定的局限性,临床上可联合多种指标明确胸腔积液病因,指导治疗.

Diagnostic value of improved pleural biopsy combined with biomarker in pleural effusion of unknown origin

Objective To investigate the diagnostic value of improved pleural biopsy combined with biomarker and cytology detection in pleural effusion of unknown origin.Methods The clinical data in 216 cases of pleural effusion were respectively analyzed including 106 cases of tuberculous pleural effusion(tuberculosis group) and 110 cases of malignant pleural effusion(malignant group).All cases were performed the improved pleural biopsy,cytology examination and detection of pleural effusion ADA,CEA and LDH,and serum CEA.The pleural biopsy diagnosis rate was performed the statistics,and pleural effusion ADA,CEA and LDH,serum CEA,and pleural effusion CEA/serum CEA were compared between the two groups.Results Among 216 cases,241 times of pleural biopsy puncture were conducted,the first time puncture success rate was 94.9 ％ (205/216).Having the diagnostic value among pathological results of pleural biopsy materials in first puncture success accounted for 58.8％ (127/216),and the overall diagnosis rate was 65.3 ％ (141/216).The incidence rate of adverse reactions was 5.8 ％ (14/241).In the tuberculosis group,no case showed cytology tumor cell positive,while the cytology tumor cell positive rate in the malignant group was 54.5％ (60/110);pleural effusion CEA and LDH,serum CEA and pleural effusion CEA / serum CEA levels and positive rates in the malignant group were significantly higher than those in the tuberculosis group,while the pleural effusion ADA level and positive rate were significantly lower than those in the tuberculosis group the difference was statistically significant(P＜0.01).Conclusion Improved pleural biopsy,pleural effusion cytology,pleural effusion biomarkers have a certain limitation in alone auxiliary diagnosis of pleural effusion.The various indicators can be combined to determine the etiology of pleural effusion in clinic for guiding treatment.
