目前,痰液细胞学检查已成为肺癌诊断的重要方法之一。其阳性率国外报道在70～75％左右。国内约50～80％。我们从1984年元月至1990年12月底共检查9869例,检出癌细胞者为2055例、其中鳞癌1420例、腺癌550例、未分化癌85例、肉瘤2例,阳性率20.08％。我们的体会是: 1 痰液标本 事前应对患者说明检查痰液之目的、方法及对疾病诊断的意义。患者先要漱口。然后咳出喉头的痰弃去。最后做深呼吸从肺部深处咳出新鲜痰液放在防水的干净容器内。立即送检;以晨痰为佳。
At present, sputum cytology has become one of the most important methods for the diagnosis of lung cancer. The positive rate of foreign reports is about 70 to 75%. About 50-80% in China. We examined 9,869 cases from January 1984 to the end of December 1990. Among them, 2,055 cancer cells were detected, including 1,420 squamous cell carcinomas, 550 adenocarcinomas, 85 undifferentiated carcinomas, and 2 sarcomas. The positive rate was 20.08%. . Our experience is: 1 Sputum specimens should be prepared in advance to explain the purpose of the examination of sputum, methods and significance for the diagnosis of the disease. The patient must first rinse his mouth. Then cough out the throat and discard it. Finally, take a deep breath and cough up fresh sputum from the deep lungs in a clean, watertight container. Immediate inspection; better morning.
