Abstract PDF: In order to evaluate the role of cytopathologic diagnosis of sputum, bronchial washing and bronchial brushing in the diagnosis of lung cancer, we performed this study. The patients included in this study had undergone sputum, bronchial washing and brushing cytology over the 20-month period of 1985 through 1987. The total number of specimens was 5,495 of 2,242 patients, including 4,830 sputa and 665 bronchial washing and brushings. The average number of sputa and bronchial washings and brushings per case was 2.4 and 1.2 respectively. Among them, about 10% were unsatisfactory specimen, and three-fourths were negative specimens. In sputum cytology, the diagnosis of "atypical cells" was given to 3%, "suspicious for malignancy" was given to 1 %, and "malignancy" was given to 13%. In bronchial washing and brushing cytology, the diagnosis of "atypical cells", "suspicious for malignancy" and malignancy" was given to 6%, 3%, and 20% respectively. The cases diagnosed as "atypical cells" in cytology were actually malignancy in 95% and 84.8% of sputum and bronchial washing and brushings respectively, and the "suspicious for malignancy" were actually malignancy in 100% in both methods. The detection rates of malignancy were 50.4% and 55.2% in sputum and bronchial washing and brushing respectively, and the specificity was 100% in both methods. The accuracy of cell typing was 92% in sputum and 89.7% in bronchial washing and brushing.

Abstract PDF: A prospective survey of sputum cytologic specimen was performed for 16 months from Jan. 1993 to Apr. 1994 in Presbyterian Medical Center. The purpose of this study is to find the positive rate of sputum cytology in the diagnosis of lung cancer and to correlate these results with tumor location and stage. Sputum cytologic specimen were received from 104 patients among 168 patients diagnosed as lung malignancy by histologic examination. Cytologic diagnosis of "suggestive of malignancy" was made in 61 patient(59%) and dysplasia in 9 patients(9%), atypia in 14 patients(13%), benign in 15 patients(14%) and inadequate specimen in 5 patients(5%), respectively. Among 84 patients beyond the cytologic diagnosis of atypia, 51 patients(61%) disclosed a central location, while 33patients(39%) showed peripheral lesions. All 54 patients diagnosed as suggestive of non-small cell carcinoma were stage III or over, and all 7 patients diagnosed as suggestive of small cell carcinoma were in advanced stage.

Abstract PDF: A case of metastatic mucoepidermoid carcinoma of the lung, originating from the hard palate, was diagnosed by sputum and bronchial washing cytology. Although the cytologic features of mucoepidermoid carcinoma have been well described, it is easy to confuse mucoepidermoid carcinoma with the more common primary adenocarcinoma or squamous cell carcinoma of the lung. The features distinguishing mucoepidermoid carcinoma from other primary neoplasms includ 1) mucus-secreting cells individually and in clusters admixed with other cell components, 2) epidermoid cells identified by the presence of abundant spread-out cytoplasm and an oval dark nucleus and 3) intermediate cells resembiling normal ductal epithelial cells with moderate-toscanty cytoplasm, a central, round vesicular nucleus and a prominent nucleolus, The morphologic features of metastatic mucoepidermoid carcinoma in the case were similar to those of primary sallvary mucoepidermoid carcinoma.

Abstract PDF: Cytopathologic findings of two cases of adenoid cystic carcinoma of the trachea are reported. The carcinomas grew as a intratracheal mass. By bronchial washing, brushing and/ or post-bronchoscopic sputum cytology, large cohesive sheets, lobulated clusters, or three dimensional ball-like structures were obtained. They had numerous cyst-like spaces containing characteristic globular basophilic material. The tumor cells were uniform and had a small amount of cytoplasm. Nuclei were small and hyperchromatic. Nucleoli were occasionally observed. The cytological diagnosis was confirmed by bronchoscopic biopsies.

Abstract PDF: To evaluate the role of sputum and bronchial washing for the diagnosis of lung carcinoma, we studied the sensitivity of both cytologic techniques using the biopsy confirmed cases from 228 patients. Among them, 123 cases were squamous cell carcinomas, 42 cases were adenocarcinomas, 48 cases were small cell carcinomas, one case was large cell carcinoma, and 14 cases were other types of carcinoma including poorly differentiated carcinomas. Three hundreds and ninety two sputa and 173 sputa were obtained in the pre- and post- bronchoscopic periods. Bronchial washing had been taken once in each patient. The overall sensitivity of the sputum cytology was 0.52 and that of the bronchial washing 0.63, while it increased to 0.83 when a combination of both techniques. Squamous cell carcinomas were diagnosed to the great extent in which sensitivities were 0.59 and 0.74, in sputum and bronchial washing, respectively. The post-bronchoscopic sputa showed higher sensitivity (0.44) than pre-bronchoscopic sputa (0.30). The sensitivity of sputa increased from 0.34 to 0.49 when three samples were examined compared to the single examination. The accuracy of cell typing was 94.0% in sputa and 93.8% in bronchial washing. Repeated sputum examination including post- bronchoscopic sputa is warranted to improve sensitivity and a complementary role of both cytologic techniques can be postulated by these data.

Abstract PDF: To analyze the accuracy and usefulness of sputum cytology as a screening method, 103 cases of histologically proven lung cancer registered from 1998 to 2000 at Kangbuk Samsung Hospital were retrospectively examined. We reviewed the original cytologic and surgical diagnoses for the cases, and the cytology slides of all cytologically negative cases. The overall sensitivity of sputum cytology was 0.83 ; the sensitivity of prebronchoscopy sputum cytology for bronchogenic carcinoma was 0.87. Central tumor location (P=0.002), tumor size (>2.4 cm), (P=0.027) and the number of sputum samples (> or =3) (P=0.001) were associated with a positive cytologic diagnosis. Of the 18 cytologically negative cases, 9 cases (38% of smears) were determined to be insufficient for diagnosis, due strictly to low cellularity and saliva. After a review of the cytology slides of cytologically negative cases, we identified several atypical clusters in one case of bronchioloalveolar carcinoma. This negativity was thus attributed to an interpretation error (1/18, 5.6%). Our results suggest that its sensitivity is more strongly related to the specimen adequacy and the times of sampling than to interpretation error. In terms of sensitivity, specificity, accessibility, cost, and morbidity associated with the screening tests, sputum cytology was found to be an accurate effective screening method for lung cancer.
