Recently the number of central type early lung cancer is increasing. In these cases, it is of importance to obtain specimens by bronchial brushing from small lesions or from where forceps cannot reach. Furthermore differential diagnosis between cancer cells and cis or severe metaplastic cells is important. So the quality of the specimen obtained by bronchial brushing is necessary to help its diagnosis.
We developed a new brush wash kit and investigated its usefulness. Compared with conventional brushing cytology, brushing-washing cytology was found to have the following advantages 1. more number of cells, 2. better cellurarity, 3. no dry specimens, 4. effective screening, 5. possibility of preservation of specimens for other special stains, and the following disadvantages 1. necessity of added process (centrifuge), 2. more expensive.
This method does not prolonged examination time and is harmless and is easy. This method has much diagnostic potential in the diagnosis of lung cancer.
