目的 研究CA19- 9在胃癌手术患者腹腔灌洗液中的含量及其临床意义。方法 应用放射免疫法测定55例胃癌患者腹腔灌洗液CA19 9的含量。结果 胃癌腹腔灌洗液CA19- 9检测阳性率为40. 0%(22 /55),明显高于脱落细胞的检出率23. 6% (13 /55)。结论 腹腔灌洗液CA19- 9检测比脱落细胞检查更准确、敏感,对判断胃癌腹膜隐性播散和患者预后有一定的指导意义。
Objective To study the content and clinical significance of CA19-9 in peritoneal lavage fluid of gastric cancer patients. Methods The content of CA19 9 in peritoneal lavage fluid of 55 patients with gastric cancer was determined by radioimmunoassay. Results The positive rate of CA19-9 in gastric peritoneal lavage fluid was 40.0% (22/55), which was significantly higher than that of exfoliated cells (23.6%, 13/55). Conclusion The detection of CA19-9 in peritoneal lavage fluid is more accurate and sensitive than that of exfoliated cells, which is of guiding significance in judging the peritoneal recessive dissemination of gastric cancer and the prognosis of patients.
