脱落细胞学检查、DNA 倍体分析与血清肿瘤标志物联合检测诊断恶性胸腹水的价值

摘要

Objective:To compare the clinical value of the detection of exfoliative cytology,serum tumor markers and DNA heteroploid analysis in the diagnosis of malignant pleural effusion and ascite. Methods:The exfoliative cytology, serum tumor markers, DNA heteroploid analysis in 128 patients with peural effusion and ascite were investigated, the sensibilities between three tests were compared. Results:The positive rate of exfoliative cytology testing was 43. 75%. The positive rate of exfoliative cytology joint DNA heteroploid analysis was 83. 33%,with individual exfoliative cytology,the positive rate was statistically significant(P<0. 01). The positive rate of serum tumor markers joint testing was 81. 25%, the difference had statistically significant compared with CA125 and AFP single detection(P<0. 01). Conclusions:The jiont detection of exfoliative cytology,serum tumor markers and DNA heteroploid analysis can improve the detection rate of malignant pleural effusion and ascite.%目的：：比较脱落细胞学检查、DNA倍体分析与血清肿瘤标志物联合检测对恶性胸腹水的诊断价值。方法：对128例患者胸腹水同时进行脱落细胞学检查与DNA倍体分析，并抽取静脉血作血清肿瘤标志物检测，比较三者敏感性。结果：脱落细胞学检查阳性率为43.75％。恶性胸腹水脱落细胞学检查联合DNA倍体分析的检测阳性率为83.33％，与单项脱落细胞学检查的阳性率差异有统计学意义(P<0.01)。血清肿瘤标志物联合检测阳性率为81.25％，与血清标志物癌抗原125和甲胎蛋白单项检测差异均有统计学意义(P<0.01)。结论：脱落细胞学检查、DNA倍体分析与血清肿瘤标志物检测联合运用，可提高恶性胸腹水的检出率。
