Diagnostic utility of cell-block from bronchial washing in pulmonary neoplasms.
In order to evaluate the usefulness of cell-block (CB) bronchial washing in the diagnosis of pulmonary neoplasms, we examined cytological samples of 1,145 bronchoscopies; CBs could be prepared in 777 cases (67.9%) and 201 cases, positive or suspicious for malignancy, were selected for the study (173/201 smears: 86.1%; 174/201 CBs: 86.6%). CBs were positive in 12 cases while the corresponding smears were negative (10 cases) or suspicious (2 cases); 2 cases had suspicious CBs with negative smears. Thus, the use of CBs increased the positive diagnosis from 173 to 185 cases, for an increase of 6.5%. We can conclude that CB could be a routine, inexpensive method, helpful in pulmonary neoplasm's diagnosis; moreover, CB has the advantage of being an histologic specimen, often the only one, useful for other diagnostic procedures.
