痰液癌细胞学检查,是检查肺癌的重要手段之一。但是肺部肿瘤细胞能否随痰排出体外,是痰细胞学检查成败的关键。以前我们虽然用了很多方法检查痰细胞,但诊断阳性率仅达30%左右,尤其 X线检查很典型的肺癌经反复查痰仍为阴性。故此,我们采用新斯的明诱痰和痰液浓缩制片法,检查痰细胞55例次,阳性者40例次,阳性率为72.7%。效果满意,现将其方法介绍如下。 Sputum cytology, lung cancer is one of the important ways. However, the lung tumor cells can be excreted with the sputum, sputum cytology is the key to the success or failure. Although we used a lot of methods to check sputum cells before, the diagnostic positive rate was only about 30%. In particular, lung cancer with typical X-ray examination was still negative after repeated sputum aspiration. Therefore, we use neostigmine induced sputum and sputum concentration preparation method, check the sputum cells in 55 cases, 40 cases were positive, the positive rate was 72.7%. Satisfactory results, now the method described below.
